The new feeders of the «Gió» range, specifically developed for great poultry farms, thanks to the easiness in the regulation of the feed and to the absence of grill (that avoid chicks perching) have many advantages: they are easy to use and their cleaning is extremely easy and fast too, leading to an overall reduction in labour costs.

EDITORIAL Poultry products represent a great part of the display in butcher shops and on the butcher counters of supermarkets. There is a wide assortment, which ranges from whole, oven-ready chickens to convenience products. During the last few years, no other meat sector has done so well. This growing interest depends on the introduction of new products, the nutritional and dietary qualities, as well as the new positive image of poultry.

On the other hand, however, some fundamental difficulties remain. The first that comes in mind is the outdated pricing system. It is a real paradox that, after many years of radical change in the production, processing and distribution of poultry, the pricing system is almost immutable.

The predominance of non-brand products represents another underlying contradiction. Brand loyalty is a marketing goal, and producers are investing in innovating, in new brands and trademarks, which aim at capturing consumer confidence by offering health and quality guarantees. This is certainly possible today as a result of evolution of the processing companies. Today’s consumer is aware that the processing industries offer the very best guarantees of hygiene. However, these products are more costly and the public is still choosing to save a few pennies.

The processing industries, together with the large-scale modern distributors, have been successful with products, which are quick and easy to prepare, in portions which enable the consumer to create personal and appealing menus.

A wide gamma of chicken and turkey products is already on the market. Chicken and turkey breasts are the most popular of the traditional products.

The consumer still has the last word and the attitudes, which determine the public’s choices and preferences, are complex. There is no doubt that the poultry industry perfectly respond to any market change and consumer’s need and seems to be in an excellent position to maintain the trust of the public.

USPOULTRY and the USPOULTRY Foundation announced the completion of a funded research project at the U.S. National Poultry Research Center, USDA ARS, in Athens, Ga., in which a researcher completed initial steps toward developing an experimental vaccine that may provide better Salmonella control in poultry.

Dr. Hung-Yueh Yeh, at the U.S. National Poultry Research Center, USDA ARS, in Athens, Ga., recently finalized a research project in which he completed the initial steps toward developing a vaccine to protect poultry against multiple serotypes of Salmonella. He identified and purified multiple proteins from Salmonella which when combined in a vaccine provided significant protection against Salmonella colonization of the intestinal tract of chickens.

Further refinement of this experimental vaccine may provide a valuable food safety tool for the poultry and egg industry.

BD Agricoltura Italia headquarters

BD Agricoltura Italia – meet the team (left to right): Sergio Ferri, Giulia Ferri, Mirco Gautieri

BD Agricoltura Italia in new offices with warehouse for increased local presence Big Dutchman establishes a subsidiary in Italy Big Dutchman, the poultry equipment supplier from Germany, is now present with a subsidiary in Italy, which started operating from Castiglione delle Stiviere recently. The new premises have 120 square meters of office space and 430 square meters of storage space. The subsidiary’s location in the valley of the Po in Northern Italy was selected for a good reason: the town of Castiglione is situated in the hub of the Italian poultry industry.

“We believe in the potential of this market. Founding BD Agricoltura Italia was therefore a logical step to increase our local presence and truly place our focus on the customer,” explains Big Dutchman Area Sales Manager Frank Moormann.

In the past, the Italian market was served from Germany. “With our own warehouse, we can meet our customers’ needs much quicker,” says Sergio Ferri, Managing Director of BD Agricoltura. The portfolio of the market leader for housing equipment in poultry production includes traditional and computer-controlled feeding systems as well as poultry climate control and exhaust air treatment systems. The scope of services ranges from small to large, fully integrated turnkey poultry farms.

A new exhibition hall will display the Big Dutchman product range in Castiglione delle Stiviere. “Having the actual products here helps us demonstrate how our poultry equipment works.

An exhibition hall is also a great platform for presenting industry trends with regard to animal welfare and environmental protection,” states Ferri.

Many poultry keepers in Italy already know the newly appointed managing director. He has been working with and advising Big Dutchman customers from Italy for several years now. Ferri and his team in Italy have many years of experience and an outstanding knowledge of poultry equipment. They equip new houses and also always find innovative solutions when renovating old ones.

AVIAGEN® Ranger Gold

COMPANY NEWS

Aviagen’s slower-growing Ranger Gold makes inroads into German market Ranger Gold achieves accreditation by German animal protection organization, demonstrating commitment to animal health and welfare.

Aviagen® is pleased to announce that its slower-growing breed, the Ranger Gold™, has been awarded full accreditation by the German animal protection organization Tierschutzlabel, Deutscher Tierschutzbund e.V. (DTSchB).

The Ranger Gold is part of the Aviagen Rowan Range® product portfolio and yields excellent welfare characteristics, as well as reliable meat production performance and ease of management.

“On the basis of the information given by Aviagen, the Deutsche Tierschutzbund e. V. has approved Ranger Gold to be used in the certifi cation scheme of the Tierschutzlabel ‘Für Mehr Tierschutz’ trademark,” said Inke Drosse, head of the department farm animals, Deutscher Tierschutzbund.

Future looks “golden” for slower-growing breeds The Ranger Gold offers considerable advantages to growers, such as favourable meat yield, consistently strong production performance and excellent feed conversion.

Various retail chains have recently announced a move toward organic, slower-growing and free-range poultry based on a growing consumer demand worldwide.

Aviagen anticipated the need for breeds aligned to the needs of this emerging market early on, and developed the Rowan Range portfolio of slower-growing and colored-feathered birds for this segment, which is gaining traction, especially in Europe and the U.S.

R&D focus brings to market broad consumer choices A major strength for Aviagen has always been the genetic-line diversity of its R&D program. This diversity has enabled the company to consistently offer a wide selection to address a range of market needs.

“To help our customers remain competitive, Aviagen’s goal is to proactively respond to ever-advancing consumer requirements,” says Henk Steenblik, Commercial and Technical Manager, Aviagen EPI. “We are currently seeing an increasing interest in slower-growing breeds across the region and further afi eld in Europe, and have developed the Ranger Gold specifi cally for customers in this niche market segment. Along with a slower-growing option that gives performance and productivity, customers benefi t from the long-term knowledge and experience of a company that thoroughly understands their challenges and is committed to their success.”

Focus on animal health and welfare Animal health and welfare has always been the highest priority in every aspect of Aviagen’s breeding program. In addition to DTSchB accreditation, the Rowan Range slower-growing products have met the criteria for many accredited animal welfare programs worldwide, including the Royal Society for the Prevention of Cruelty to Animals (RSPCA) in the U.K. and Beter Leven (Better Life) in the Netherlands.

REPORTAGE

First stop in Venice

The Great Journey This title was the pleasant theme given by Massimo Finco to the celebration of 60 years of activity recorded by the Facco company headquarted in Marsango (Padua). A great festival, the essence of which went beyond commercial interests, as intended by the host, to embrace convivial moments and to create an opportunity for social and cultural exchanges.

The event took place from 6th to 8th September, and included guided tours of Venice and Padua and concluded with a grand gala evening in the company's renovated Marsango home.

The inspiration for the theme given to the event was born out of the idea of linking the Facco company to a profoundly motivated hypothetical

This day's activities concluded in Padua with an exclusive visit to the Basilica of Sant'Antonio, rich in art masterpieces and food for thought on the compassionate figure of a Saint open to embracing various other cultures and religions.

The 8th September also commenced with an insight into art and culture during a guided tour of Padua University, the second oldest university in the world founded in 1222 and where Galileo Galilei lectured. This institute remains to this day a nursery where well-trained students are encouraged and nurtured ready to implement innovation and research. These values are hugely shared by the Facco company and the company continues to have a close collaborative rapport with the university.

The New Facco In January 2016 a large fire caused considerable damage to the company headquarters at Marsango and, as commented

The programme for the 8th September included a visit to these new production and logistics units.

At the company headquarters activities are concentrated on R & D; engineering; operations; production control and quality.

The reorganization phase really took birth between the end of the last century and the beginning of the present one, when Facco transformed itself from an international company into a multi-national corporation, capable of also providing a better bespoke solution to customers local needs thanks to a local production and presence.

During the factory visit, a highly efficient and state-of-the art facility, we were shown various equipment at work, futuristic and sophisticated machines capable of producing high quality components with unique quality control and certification. All departments are divided by colour to make it easier for staff to identify various production sections. The level of sophistication

is very high and almost unique, suffice to say, that Maserati turned to a Facco facility to produce component parts for its 4-door model.

In the paint and welding departments for example, there are avant-garde robotic machinery which, with utmost precision under the guidance of specialized personnel, machine and assemble individual parts, even those with nanotechnological applications.

To ensure a long service life for equipment destined for use in varying farming operations, particular attention is paid to the quality of the raw materials used particularly with regard to counteracting the appearance of rust which is a major problem.

The Facco company carry out extensive tests and checks to ensure that each of their products are reliable and up to required standards.

The company's logistical requirements are entrusted to a shipping company that effectively manage the continuous flow of Facco products destined to be shipped all around the world.

The industrial area where the Facco company and its 30 subsidiaries and joint ventures are located, covers tens of thousands of square meters in the northeastern area of Padua with the company's headquarters building covering 40,000 square meters. Hundreds are employed in the area including the 150 Facco employees.

join them on this occasion, Massimo Finco traced all the stages of the journey made by the company up to the present time where today we see the realization of an industrial complex with a turnover of one billion, 200 million euros and 3000 people employed worldwide. It was also an opportunity for him to thank his father and founder of the company Luigi Finco, and his mother and his many other collaborators for their constant support. Elisa Finco, the third generation of the family and a member of the Board of Directors, also presented a forwardlooking and incisive overview of the company and its future prospects.

In his conclusive remarks, Massimo underlined how entrepreneurial insight had anticipated future market needs. It was precisely, thanks to the ingenious foresight of Luigi Finco and Giuseppe Facco, that in the second half of the 1950s, they designed the first automatic cage â&#x20AC;&#x201C; anticipating the needs of today's modern poultry farming.

During this era, aware that poultry production was already developing outside Italy in countries such as the Netherlands, France and the United States, Luigi Finco and his collaborators began to make their first trips abroad including the Paris Fair, all such trips being carried out with great anticipation.

Facco quickly became a presence in international markets and new offices had to be built, warehouses extended, new investments made, and equally they had, in moments of market crisis, to find new outlets for their produced products.

The 1970s were characterized by economic growth in the Middle East which required the development of turnkey projects.

The 1980s were witness to great change worldwide as new challenges emerged, The company sought new markets to conquer such as the Asian ones of Canton and Beijing. The

company was called upon by the Beijing University to teach the new Chinese business elite how to manage laying flocks.

They also participated in an African FAO project with the sale of equipment to Algeria to encourage agricultural development in the area.

During these years Massimo Finco took up the position of CEO and another stage of “The Great Journey” commenced. Firstly the company embarked on a major marketing study covering new countries such as Australia, Japan and the United States. Business trips began to other countries such as Jordan, Pakistan, Australia etc to meet and build relationships with the major producers in these areas.

These were the years of technological change with the introduction in France of plastic cages which over a short period of years saw this material being used in all pyramid cage layouts and in the 100 meter long American cage layouts.

Massimo Finco speaking about the great journey of Facco

In these years Facco USA and Facco Japan were established with this move turning out to be a winning card in the subsequent development of the company.

Facco, already a company with strong engineering credentials, began focusing on product development, identifying new systems, improving automation and above all finding answers to market brand new requirements that differed to those previously in existence. This meant that along with their involvement in turnkey operations the company needed to provide technological innovation, ultra-modern automatic and efficient equipment systems that, in addition, would be simple to operate.

Facco thus became a global company recognized internationally as a leader in its field.

During the 90s the industry saw the introduction of layouts which were the precursor to today's alternative systems in countries such as Switzerland, Austria and Great Britain. These projects were also taking place in countries further afield namely Australia, Japan and the Far East. The new century saw Facco continuing to penetrate new markets in the Middle east, America and especially in the former Soviet Bloc countries with the opening of an office in St Petersburg.

Over the last 5 years turnover has doubled as have margins and investments. There was a desire to penetrate the Latin American market from within and to this end the company purchased the important Brazilian company Artabas.

In a drive to increase market presence new offices have been opened in Moscow Russia, in Beijing China, and in the United States in Chicago, where new innovative forms of supplying have been studied not only regarding the product range but also regarding customer service.

During this time “cage free” systems have come to the fore which has led to fundamental changes within the company. Interesting to think that in 2016, 50% of turnover was for product lines that 4 years previously would not have been seen on the market.

Elisa Finco presenting a forward-looking overview of the company and its future prospects

The Facco company is involved in 40 countries around the world. Today the company has a strong manufacturing heritage and produces solid products and has an ever-increasing global presence. It continues to research, develop and innovate ready to face future challenges and continually keeps customer and market needs at the centre of company thinking. It is a company that uses revolutionary logistics as it integrates production across the globe. Digital realities, which bring together engineering skills, poultry knowledge, electronics, environmental and animal welfare issues, are all used to create the “know how” which help the company anticipate market demands.

The Facco of today not only produces the numbers but also capitalizes on its experience by actively cooperating with universities and research centres giving encouragement to the young and innovation. A heritage born out of years of operating at a world level, where diversity and sharing with clients at both a personal and professional level are fundamental facets of life.

“The end of a trip is just the beginning of another”, stated Massimo Finco quoting a famous comment by José Saramago.

There is therefore no need for fast or high capacity distribution systems nor does the grower need to raise or lower the line for the fi lling and distribution of feed and neither is there a need for a weighing scale. Everything is handled by the SELF-DOSY dispenser system.

Like all our feed lines, the SELF-DOSY is easy to clean; the bottom of the pan is easy to remove which allows for a convenient and complete cleaning of all the internal parts”.

The anti waste ring, used during the transition from the fi rst to the second growing phase can be mounted and dismantled quickly without the need for screws or tools. It is also securely fi xed to withstand any impact.

The optimum depth of the feed pan ensures birds can easily access the feed from day old and do not try to enter the feed pan. The top part of the feed pan is made from fl exible rubber material which withstands impact and causes no bird damage.

Biostreamer HD - Petersime

A new specialised turkey hatchery for Turkmenistan An interview to Mr. Maksat Ibragimov, Company Coordinator MAKSADA OKGUNLY A new hatchery complex near Ashgabat, the capital of Turkmenistan fully equipped with Petersime BioStreamer™ 4TS setters and a BioStreamer™ 4TH hatcher.

What you are constructing is more than a new turkey hatchery in Turkmenistan. You are building a complete complex for producing turkey meat.

“That’s right. My sister Zerey Ibragimova and I are building a complex that includes a hatchery for incubating turkey eggs. We purchased the hatchery equipment from Belgium, 22 turkey houses from Germany, the slaughterhouse from France, the complex for deep meat processing from Italy and other European countries, and specialised feeds from Germany. Our complex is being constructed in the Gökdepe District, about 65 kilometres away from Ashgabat, the capital of Turkmenistan. Within easy reach of the complex, we have built a waste processing factory for producing bone meal and disposing of waste.”

Why is the construction of this turkey complex so important for Turkmenistan?

“Because this is a way to ensure that the country will be supplied with quality healthy turkey meat.

The Turkmen government plans to guarantee the supply of high-grade meat to the domestic market and, eventually, to export turkey meat in the long term. Our turkey hatchery, as well as the complex, will be the first specialised project in Turkmenistan to be built on an industrial scale. It will allow us to produce high-quality competitive products, which in turn will find their customers both in Turkmenistan and abroad.”

INTERVIEW

Mr Maksat Ibragimov, Company Coordinator MAKSADA OKGUNLY and FSE Igor Baryshnikov from OOO Petersime.

The Turkmen government is supporting your expansion.

How did you secure this support?

“Back in 2013, we were the fi rst entrepreneurs in Turkmenistan to import turkey eggs. For two years, we produced meat on a small scale, proving that we were capable of providing a balanced supply of turkey meat. In early 2015, our esteemed President allocated, for the second time already, US$100 million for 10 years at 1% per annum with a grace period of fi ve years. The Union of Industrialists and Entrepreneurs carefully studied the projects submitted by entrepreneurs, and eventually selected over 37 projects, including ours. The winning projects were also allocated free plots for construction and irrigation. Our company received 23 ha for construction and 230 ha for irrigation.”

What output can we expect from MAKSADA OKGUNLY? “The output will be increased gradually. During the fi rst phase, we will produce 3,200 tons of turkey meat, of which 1,500 tons will be deep-processed to manufacture more than 46 various products (link sausages, sausages, smoked products, etc.).

During the second phase, we will supply 1,600 tons more.

We have purchased four Petersime BioStreamer™ 4TS setters and a BioStreamer™ 4TH hatcher, and now, thanks to the most advanced technologies, we have the capacity to hatch 730,000 turkeys per year. Our project includes 22 houses to raise them in and a slaughterhouse that can handle 400 turkeys per hour; we can process 4,800 tons of meat per year into 65 different products. So, the Turkmen market will have a wide selection of turkey meat.”

When will the first turkeys be supplied?

“We plan to have the fi rst phase of the complex, including the hatchery, up and running by the end of 2017. It will be our New Year gift to guests and residents of Turkmenistan. According to the schedule, the second phase will be completed by the end of 2018.”

What are your plans for the future?

“First of all, we intend to launch the second phase and reach the maximum production output of turkey meat.

Further, we, together with our European partners, plan to make a technological transfer to Turkmenistan, and to start exporting hatching eggs and chicks to the neighbouring countries. We also have projects to diversify production, e. g. projects to produce duck and goose meat.

In addition, we are developing a unique project, which has never yet been implemented either in Turkmenistan or in the neighbouring countries. I assure you, this will be a sensation in the world industry”.

MARKETING

The poultry meat business in Europe and beyond It is a great challenge in a rapidly changing world to keep a business model up to date and profitable The market orientation of the poultry sector allows the industry to correlate rapid responses to consumer demands and to adapt in case of a sudden crisis.

Market orientation Market orientation is defined as “a business model which focuses on delivering products designed to meet customer desires, needs, and requirements, in addition to product functionality and production efficiency”. Poultry producers are continuously developing products; modes of production; brands and processing methods which respond to consumer needs and behaviour regarding the consumption of meat. The market

orientation of the poultry meat sector is favoured by the characteristics of the poultry meat production which include many advantages when compared to other meat sectors.

Short production cycles The short production cycle enables poultry producers to respond quickly to market signals. This short cycle also allows for rapid improvements in genetics, animal health, and feeding practic-

or lamb meat); convenience; absence of religious restrictions; health image (low fat content and good and balanced protein content) and good environmental performance with low GHG emissions. Starting a poultry business implies step by step growth with the business running comfortably alongside other agricultural activities.

Thanks to the short production cycles and lower labour and maintenance costs per unit of production should lead to a faster return on investment.

Vertical integration in the supply chain Vertical integration is organized in different ways. The strongest form is when a company is active in two or more adjacent stages of the production chain, from breeding to consumption, which sometimes includes involvement in the important feed supply stage of the chain.

Poultry companies cooperate in partnership with each other at different production stages in order to benefit from the economies of scale by grouping different activities along the production chain.

Vertical integration gives producers also the chance to respond well to specific consumer demands.

Today, in the EU poultry meat sector, vertical integration is common practice with it being essential for businesses to control all aspects of the production chain starting from the breeding activities through the hatching of the eggs; feed milling; growing of the birds then to the slaughtering and further processing of the poultry meat and finally to the delivery to consumer through the retail, food service, institutes etc. sector. Many companies are at least semi-integrated meaning that the slaughterhouse and or feed manufacture are managing the poultry supply chain in at least one other stage from the parent stock farm, the hatchery and the rearing of poultry.

Characteristics of the poultry meat The market orientation of the poultry meat sector is also reinforced by several comparative advantages when compared to other meats. Among these different characteristics one can mention affordability (the price per kg of poultry meat is cheaper than pork, beef

MARKETING

The market orientation of the poultry sector has also contributed to the development of internal and external trade in the EU. The EU poultry meat market is the most open meat sector in the EU in terms of trade as the EU is importing more than 800,000 tonnes and is exporting more than 1.4 Million tonnes to third countries. As consumers in the EU have a preference for boneless meat cuts mainly from the breast, EU production is more focused on breast meat for this EU market while the dark meat is delivered to third country markets, where this dark meat is preferred for taste or budget reasons.

This increase in consumption of chicken cuts has influenced the structure of the EU trading in a manner similar to that which occurred in the US where consumers preference for white meat lead to the exporting of the surplus of dark meat to world markets.

This market flexibility promoted increased demand for poultry meat, leading to an increase in per capita chicken meat consumption of 7,2 kg between 2000 and 2014 (from 14,8 to 22 kg per capita). On a global scale, poultry meat consumption has continuously increased over the last decades and is predicted to do the same in the future.

The characteristics and structure of the poultry meat sector offer a framework that can adapt to consumer expectations and demands. Thanks to this market orientation, poultry meat producers in the EU have successfully reoriented their businesses to match consumer needs leading to growth of poultry meat consumption.

â&#x20AC;&#x153;Today, in the EU poultry meat sector, vertical integration is common practice with it being essential for businesses to control all aspects of the production chain starting from the breeding activities through the hatching of the eggs; feed milling; growing of the birds then to the slaughtering and further processing of the poultry meat and finally to the delivery to consumer through the retail, food serviceâ&#x20AC;?

The market orientation of the sector has influenced the evolution of the European poultry meat sector over the past 10 years.

In particular the products on offer have noticeably changed in recent years with a reduction of whole chickens in favour of the more profitable cuts and processed products. Although there are clear differences between Member States with several countries (Spain, Italy, France) still traditionally consuming more whole chicken, consumer preference for chicken cuts and further processed products is widespread in the majority of Member States and is expected to continue.

Kipster farm

Dekalb White

Revolutionary layer farm Kipster officially opened The fi rst Kipster farm was officially opened. This is the most state-ofthe-art layer farm in the world. The farm is located on the Wusterveld in the town of Venray.

This area is intended for innovative agriculture, with an eye for animal welfare and the environment.

Hendrix Genetics is a proud partner in this concept and will be delivering Dekalb White laying hens to be housed at Kipster.

Hendrix Genetics has recently been partner in the realisation of an innovative layer farms which will produce and sell eggs to Lidl, one of biggest European food retail.

- field cases -

FIELD CASES

These are the main innovations realized on one farm: • A great deal of innovations has been used.

• This farm concept is designed around the instincts and needs of the chicken.

Maurits Groen of Kipster: “Our aim is an affordable egg, which has been produced sustainably and climate positive, with a clear eye on animal welfare as a starting point, and a decent income for the farmer. We have succeeded in that aim.”

• 1,100 solar panels make the farm energy-positive.

• Fuel emissions are limited to an absolute minimum using energy systems not used in the agricultural sector before.

• The facility includes an area for visitors and a center for education and information.

• The chickens eat newly developed feed made from surplus foodstuffs from the food industry which minimize the environmental impact and do not compete with food for human consumption.

The eggs will be sold directly to Lidl, one of the major retailers in Europe. Lidl will also sell the meat of the male chicks. Lidl is the first retailer in The Netherlands to do this.

Development of the Kipster farm concept Kipster is an initiative of four entrepreneurs combing expertise in the fields of poultry, sustainability, farming and communication. Four years of development went into the design of the Kipster farm. This project is truly unique as it involved numerous parties including animal welfare and sustainability organizations in the design phase. The end result is a farm concept that is future proof, flexible and scalable.

Styn Claessens of Kipster: “With common sense and the latest technology, we have built the farm of the future.”

Dekalb White an essential part of the Kipster farm concept Dekalb White laying hens are an essential part of the Kipster farm concept. With the performance of the Dekalb White it is possible to combine animal welfare and environmentally friendliness in a financially feasible way. The Dekalb White is a perfect fit for innovative farms like Kipster.

The first 24,000 laying hens arrived last September at the Kipster farm. These were Dekalb White hens from the Hendrix Genetics breeding company, reared and distributed by Belgian distributor Vepymo.

Dekalb White hens are docile in behavior, making them highly suited to this new, innovative system. Furthermore, these hens produce large amounts of eggs with an excellent shell quality.

The egg weight is very consistent with minimal increases by the end of the active laying period.

Ruud Zanders of Kipster: “Lots of innovations, and plain old common sense, make Kipster the most state-of-the-art layer farm in the world. We have the ambition to conquer the world with this innovative concept.”

Frans van Sambeek - Director Research & Development at Hendrix Genetics: “We breed for balanced laying hens that produce top quality eggs. Meaning stronger - and happier laying hens with a prolonged life. This gives our customers, like Kipster and Lidl, a more sustainable production cycle in total.”

Olivier Wegloop of Kipster: “We aim to bring poultry farms worldwide to an animal and environmentally friendly level.

There is already interest from the US, Canada and some European countries.”

Big Dutchman’s Natura Step

Great Britain changing lanes: barn or free-range egg production?

Great Britain is currently experiencing many changes, political and others. One of them specifi cally concerns the egg production in the country.

In addition to the challenges posed by the Brexit, the egg industry is facing another “exit”: Tesco, one of the country’s largest retailers, has announced that it will no longer sell eggs produced in enriched colony systems from 2025. Other major companies have also committed to going cage-free,

such as the food services provider Sodexo, whose decision includes shell eggs and liquid eggs. The supermarket chains Sainsburyâ&#x20AC;&#x2122;s, Waitrose and Aldi have already phased out eggs produced in enriched colony units. The National Farmersâ&#x20AC;&#x2122; Union, active in England and Wales, expects the industryâ&#x20AC;&#x2122;s most radical change since the ban on poultry cages in 2012. As much as 43 percent of the 1.4 billion shell eggs sold by Tesco are produced in enriched colony systems.

This means that numerous egg producers will have to refurbish their houses in the next eight years.Â

Barn egg production, not free-range egg production The Big Dutchman distributor Newquip Ltd. of Yorkshire has already noticed that the industry is gaining momentum, as illustrated by an increased interest in their systems for barn egg production, reports the renowned magazine The Ranger on its website. In a country where nearly 50 percent of all marketed eggs are free range eggs, this interest is not surprising. Only a small number of farmers affected by the phase-out has sufficient space for the required outside range. Barn egg production with the NaturaStep aviary system is therefore a genuine alternative, affirms Newquip expert Richard Buchan. The aviary can easily be installed in refurbished old houses.Â

NaturaStep â&#x20AC;&#x201C; a multi-tier open-access aviary system

Safe cleaning & disinfection

The Natura Step is a completely open multi-tiered system, giving full freedom to the birds to move in and out of the aviary at all times. The name comes from the unique steps which are designed to allow easy movement from one tier to another. These steps (as all the system's wire mesh) are made with zinc-aluminium wire coating, resulting in three to four times better protection against corrosion compared to galvanized wire.

Perches and perch placement: Thereâ&#x20AC;&#x2122;s science in design and placement of perches. They allow birds to have a place to relax, and their design provides maximum comfort. Perch placement encourages flock movement which relaxes the flock. At the same time it maximizes proper air circulation, resulting in a healthy and comfortable environment.

The patented approach perch is designed to protect any mislaid eggs. It also positions the hens to face outside of the system while roosting, allowing the manure to fall onto the manure belt, resulting in lower ammonia levels and a cleaner system.

The entire flock has easy access to fresh feed and water whenever they want it. The drinking nipples are placed outside the nests to provide birds with fresh water after they lay their eggs. Feed access is strategically placed inside the system to promote bird movement and open up quality space.

Natura aviaries: “We are one family” Big Dutchman introduced the first aviary system for egg production as a reaction to the ban on cage eggs in Switzerland 30 years ago. The production range has grown to include more than 20 different versions. Therefore, an appropriate solution can be found for every poultry house, whilst also facilitating economic and simultaneously animal- and user-friendly egg production.

Hence the list of Big Dutchman’s references is quite impressive: more than 74 million bird places have been equipped with Natura aviary systems, first in Europe and later also in Australia, Canada, New Zealand and the USA. Big Dutchman experts have implemented many customer requests and experiences to improve and further develop the Na-

Nests are located in areas that comply with the hens' sense of security. After an egg is laid, it gently rolls out onto the egg collection belt and then automatically heads to the egg packing area.

The nest average acceptance is 98%, but for those rare times when an egg is laid outside of the nest, we have built in a system egg tray to make picking up the mislaid eggs easy and fast.

Uniformity of lighting and ventilation along with system design result in even spacing of the hens throughout the house allowing the litter to dry thoroughly. This is ideal for the flock as they dust bathe, scratch, and act out other natural behaviours.

Main features:

tura aviaries in the past decades. The result: today, the Natura aviaries are a flexible and modular system. Egg producers will find a solution for virtually any situation. Whether a farmer has an old building or is planning a new one, whether the house is large or small: Natura aviary systems offer a wide range of intelligent solutions.

There is one idea at the heart of all Natura systems, whether they are intended for free range or barn egg production: an aviary system must guarantee the birds’ well-being, but also be economic. Characteristics that all Natura aviaries share; therefore including a high laying capacity, a low number of mislaid eggs, minimum inspection and management efforts and happy birds.

Dirk Mertens tests the Natural Beak Smoothing pans by Roxell

Roxell Technical Service

Beak treatment is often used as the solution of choice to reduce damage caused by pecking. Due to the growing interest in animal welfare, however, beak treatment has gradually being banned by law. Solutions that both improve animal welfare and allow time and cost efficiencies are the future.

Roxell once more takes the lead and provides a high quality and durable solution for the new market trends and upcoming animal welfare regulations.

At Roxell, they believe it is better to use nature as a reference to develop new feeding solutions. The animal behaviour and the design of their feeding systems go hand in hand.

Therefore the Belgium-based company launched the â&#x20AC;&#x2DC;Natural Beak Smoothing conceptâ&#x20AC;&#x2122;, in order to meet the specifi c market demands and animal welfare regulations.

- technical column -

TECHNICAL COLUMN Â&#x160;

Test results show that Roxellâ&#x20AC;&#x2122;s natural beak smoothing pans save feed and leads to better uniformity, reduced mortality and less stress.

Dirk Mertens talks about his test experience Today, Dirk Mertens has a rearing farm with five houses for broiler breeders 90,000 females and 10,000 males - in Wuustwezel, Belgium. He started out in the poultry sector in 1981 when he set up a commercial layers farm at another location, which he later converted to a broiler breeders production farm. His son took over that breeding farm, and since 2009, Dirk has been running the broiler breeder rearing farm together with his wife, his daughter Mieke and his son-in-law.

Responding to the behavior of birds "We've been working with Roxell products since the eighties. Initially, there were the cockerel pans. Today's houses are equipped with 7,500 Roxell Vitoo feeder pans, installed by housing specialist VSI," says Dirk Mertens. "Over the past eight years, we have gradually expanded from two to fi ve houses, for which we were able to rely on Roxell's sustainable and efficient systems, which are tailored to the behaviour of the birds.

I also fi nd it important to invest in systems that promote animal welfare. That's why, four years ago, we immediately agreed to participate in a trial project on natural de-beaking. Beak treatment has not yet been banned in Belgium, but is gradually being phased out in neighbouring countries. Our country may be expected to follow suit."Â

Testing the Natural Beak Smoothing concept From the outset, there was a close collaboration between Roxell and international breeding companies - Aviagen, Cobb and Hubbard - for testing the Nat-

ural Beak Smoothing concept. Roxell has provided the existing Vitoo feeder pans with an integrated rough structured bottom pan that naturally controls beak growth during feeding. Current beak treatments such as mechanical hot blade de-beaking and IR trimming, become superfluous, resulting in significant cost savings.

However, the advantages go much further. â&#x20AC;&#x153;I notice there is less mortality among our chicks, because they don't suffer a relapse following beak smoothing. They have less stress and can just continue eating during the fi rst days. We also notice a greater uniformity among the chicks. All these things eventually lead to a better end result,â&#x20AC;? Dirk concludes. â&#x20AC;&#x153;We've now had several fl ocks with Natural Beak Smoothing pans. Despite the fi ne structure of the metal, cleaning the pans doesn't take more time.â&#x20AC;?

On-farm traying: a smart idea?

On breeder farms eggs are traditionally collected in paper or plastic trays that each hold 30 eggs. Typically, these are stacked six-high and transported to the hatchery in boxes, crates, trolleys or on pallets.

Before incubation, hatchery staff have to transfer the trayed eggs to setter trays, either manually or (semi)-automatically. So far, each hatching egg has already been handled at least twice before incubation begins - and each time with the risk of causing hairline cracks and contamination that will ultimately undermine hatch results.

Gerd de Lange Senior Poultry specialist, Pas Reform Academy

32

On-farm traying, both manual and automatic, is becoming increasingly popular as it minimizes labour and reduces the need for egg handling. With the eggs already placed on setter trays at the breeder farm, they are then transported in specially designed farm trolleys to the hatchery, where the setter trays are transferred from the farm trolleys to setter trolleys. The eggs are not handled individually any more - and even this final transfer before incubation can be automated.

When choosing a tray type for egg collection on the farm and subsequent transport to the hatchery, there are several important considerations that will also have important consequences for managing the hatching eggs:

- technical column -

TECHNICAL COLUMN

Rate of cooling down Egg temperature at the moment of collection varies from egg to egg. For those still holding a temperature of >25°F/77°F, further cooling is required. When placed at the centre of a paper tray and covered by the next full tray, a newly laid egg with a temperature closer to that of the hen’s body (41°C/105.8°F), will take much longer to cool down than an egg placed at the side of the paper tray. And packing warm eggs on paper trays directly into egg boxes will certainly lead to high embryonic mortality.

With a more open construction and the fact that they are not stacked directly on top of each other, filled setter trays allow sufficient freely circulating air to pass around the trayed eggs.

This greatly promotes uniform cooling, but if temperature in the egg collection room is too low, there is a risk that the eggs will cool too rapidly, especially if exposed to cold air or a draught.

Plastic trays provide a mid-point between paper trays and setter trays, because plastic is not as good thermic insulator as paper and it will allow some air flow over the eggs.

bryonic structure and hairline cracks in the shell. Eggs are generally very well cushioned when transported on paper trays, so where road conditions are poor or trucks have poor suspension, paper trays may be the best choice. In other cases, well-designed setter trays without sharp edges provide good support for the hatching eggs and, when placed in farm trolleys with shock absorbing wheels, offer a valid alternative.

Further treatment of hatching eggs Placing eggs on setter trays is essential for effective disinfection or pre-storage incubation, neither of which is possible when eggs are tightly packed together on paper or plastic egg trays, as there is no free space around each egg.

Advice • Think broadly about the various ‘touchpoints’ that hatching eggs will be subjected to from farm to hatchery when choosing a tray type.

Mechanical impact

• Choose paper trays when road or vehicle conditions from breeder farm to hatchery are poor.

During loading, transport and unloading, shocks and jolts should be avoided, both to prevent damage to the fragile em-

• Recognise that eggs on setter trays may cool down too quickly after egg collection; do not place them immediately in the cold room.

Roles of certain parts of the digestive tract of chickens seems to have been lost with the evolution of time and commercial practices. Gizzards no longer serve their grinding purposes, having become more like transit organs and crops have lost their function with the abandonment of discontinuous feeding systems.

The extremely fast transit time in the anterior digestive tract is regarded as a limitation to the performance of exogenous enzymes. Manipulation of feed retention time in these gut segments via meal Table 1 Chemical composition of experimental diets, as calculated AME Kcal/kg

feeding vs. ad libitum, lighting management programs, presence of structural components in the diet and coarse vs. fine feed particles may further enhance the efficacy of exogenous enzymes.

Following an adaptation starter period until d10, six-hundred twenty four one-day-old ROSS 308 male broilers were subjected to two different lighting programs (referred to as ‘continuous’ – 18L:6D or ‘intermittent’ – 1L:3D:1L:3D:1L:3D:1L:3D:2L:6D) and fed isoenergetic (on an ME basis) and isonitrogenous wheat-, sorghum- and soybean meal-based diets (Table 1) with or without the supplementation of phytase and xylanase over 34 days.

Chicks were randomly allocated to eight treatments (2x2x2) with six replicates per treatment. Data were analysed using ANOVA (SPSS Statistics, ver. 24). Means were compared using the Tukey multiple range test.

At d10, after the initial adaptation period, body weight (BW) of chicks was virtually the same for both treatments (290 g vs.

288 g, for continuous lighting (CL) and intermittent lighting (IL) groups, respectively).

At d34, birds submitted to CL were numerically heavier than those in IL (2,224 g vs. 2,159 g, P = 0.08) and presented statistical significant higher mortality-corrected FCR (FCRc) (1.390 vs. 1.370, P = 0.003). Phytase supplementation significantly (P = 0.004) improved final BW (2,247 vs. 2,137 g, for supplemented and unsupplemented bids, respectively) and FCRc was numerically better for supplemented animals (1.375 vs. 1.286). Xylanase addition to basal diets significantly (P = 0.001) improved FCRc (1.370 vs. 1.391, for supplemented and unsupplemented bids, respectively).

There was a statistical significant (P < 0.05) interaction between phytase and xylanase supplementation on final body weight, which shows the additive/synergistic effect of these enzymes. No further interactions were observed between factors.

Further markers’ and digestibility analysis will help understand the exact mechanism through which these improvements were achieved. So far we hypothesise intermittent lighting had an effect on feed retention in the upper gastro-intestinal tract, evidenced by the lower pH found in the crop and gizzard of birds in IL groups (data not shown), and that this enabled better digestibility of nutrients. Also, phytase-activity analysis will hopefully explain why phytase supplementation did not seem to have a positive effect in IL birds further to that achieved with CL.

Dermanyssus gallinae, a wide concern for medical science The potential health risk presented by bird mites such as Dermanyssus gallinae is exacerbated by the fact that they can carry and transmit zoonotic diseases.

- management -

Parasitic bird mites present a significant threat to poultry production. Increasing reports of bird-mite attacks on humans suggest that avian ectoparasitosis (gamasoidosis) may be of increasing medical concern. This may be of particular interest to those living or working in close association with poultry, as the species most often responsible are typically linked with domestic fowl (i.e. Dermanyssus gallinae and Ornithonyssus sylviarum). Though the threat that bird mites pose to poultry is relatively well understood, the risks posed to humans have been less well explored.

ŠParis Farmers Union

MANAGEMENT

The potential health risk presented by gamasoidosis is exacerbated by the fact that bird mites such as D. gallinae can carry and transmit zoonotic diseases. Though the vector capacity of these mites is still an emerging science, mite-to-bird transmission has been demonstrated in a number of cases for D. gallinae - first reviewed by Valiente Moro et al., 2009 and later updated in George et al., 2015 -, increasing the likelihood that relevant diseases carried may also be passed from birds to mammals, humans included.

Examples of disease spread to humans through bird mite vectors are rare in the literature, though transmission of spirochetes, rickettsiae, Salmonellae, Bartonellae, Pasteurellae, Sporozoa, hemogregarines, fl agellates, and fi lariae have all been suggested, with more recent evidence supporting acquisition of Bartonella via Dermanyssus spp. per se.

The results of a recent review support that reported cases of gamasoidosis are increasing throughout the globe, with evidence that the majority of cases are linked to D. gallinae, and that mammalian companion animals and livestock may also be at risk.

Table 1 Results of a preliminary survey of suspected gamasoidosis in a selected internet user group.

Method: Members of a selected internet user group (birdmites.org) were asked to complete a basic questionnaire on their experience of gamasoidosis. This user group was composed of global members afflicted with avian mites.

Historically, group membership ranged in the hundreds, though at the time of survey (Oct-Nov 2012) activity was limited to around 25 individuals.

Questions, criteria and responses are summarized below.

PCO = Pest Control Organization SE = standard error * Information not extractable from one respondent. **Treatment type unknown in one respondent; treatment not yet attempted in one respondent. ***Treatment not yet attempted in one respondent.

Further survey data from a subset of individuals afflicted by gamasoidosis confirm wide-spread occurrence, supporting the vector capacity of the mites responsible and adding Lyme disease to the expanding list of pathogens potentially transmitted by these mites (Table 1). Other issues identified through this survey included widespread misdiagnosis of gamasoidosis and (in some cases related) treatment failure and persistent infestation (Table 1).

Diagnosing gamasoidosis based on presenting symptoms (as is often undertaken) is inadequate and a suspected cause of large-scale misdiagnosis for similarly presenting parasitoses, such as scabies and pediculosis, general dermatitis or physiological conditions including delusional ectoparasitosis. Treatment is equally problematic, with species such as D. gallinae being hard to target and widely resistant to standard acaricides.

Furthermore, the different mite species concerned display varied ecologies - with some living on hosts and others residing off hosts and feeding intermittently - that necessitate divergent treatment approaches. In cases of human infestation, positive identification of species, or at least functionally similar groups based on life-history patterns, and recommendation of suitable treatment requires an understanding of mite taxonomy and ecology that many healthcare professionals and pest control organisations do not currently possess.

38

Overall it appears that although reported cases of gamasoidosis on humans remain relatively rare, D. gallinae represents a species of particular concern to medical health due to its reported genetic plasticity, occasional evidence of permanent infestations on mammals, and high vector potential. Previous review suggests that incidences of gamasoidosis per se may be exacerbated by increased mite-novel host encounter rates and occurrence of certain ‘risk factors’ in the ‘new’ host, such as a breakdown in immune function. It follows that rising human populations, with anticipated increased incidences of immunocompromised individuals as a result of modern medical practises, may further promote gamasoidosis.

Though only preliminary, work in this area suggests that more attention should be given to gamasoidosis as a threat to human health, supporting that the mites responsible, and especially D. gallinae, could be considered an ‘occupational hazard’ to those working with poultry.

Though cases of gamasoidosis have been reported since the 17th century, documented in the leading medical literature since at least the 1920s and reviewed twice in the last 15 years, the full extent of gamasoidosis as a threat to human health has still to be explored.

Evaluating hen behaviour and physiological stressors during ventilation shut down

Project No. BRU007 Evaluating hen behaviour and physiological stressors during VSD for the development of humane methodologies for mass depopulation during a disease outbreak Kenneth Anderson, Ph.D. North Carolina State University, USA

40

The completion of a funded research project at North Carolina State University in Raleigh, N.C. was announced in which researchers provided insight on using ventilation shut down as a humane depopulation method. USPOULTRY approved $550,000 in emergency funding in October 2015 to support further Avian Infl uenza research and communication. This research is the third project completed with the funding. A brief summary of the completed research is shown below.

In 2015, the egg industry was hit with the worst highly pathogenic Avian Influenza outbreak in U.S. poultry history. Timely depopulation was identified as a critical measure to contain the outbreak. Current depopulation methods, including CO2 kill carts, CO2 injection and fire-fighting foam, were quickly overwhelmed and prolonged the suffering of infected birds.

- management -

MANAGEMENT

The overall goal of this project was to evaluate welfare parameters of ventilation shut down (VSD) for depopulating laying hens in caged systems through monitoring environmental parameters, behaviour and stress physiology.

The specific objectives were to: 1) determine the time to brain death from VSD using electroencephalograms (EEG), and

This project provided the means to develop and evaluate VSD and other depopulation methods including VSD combined with heat (VSDH) and CO2 (VSDCO). The first aspect of this project was to develop an environmental profile of an individual hen housed in a cage layer facility. Environmental conditions included building volume (3.4 ft3/hen) and temperature, relative humidity (RH) and CO2 recordings to understand the dynamics within the environment for each method. This allowed for the determination of the duration to time of death (TOD). The environmental temperature, CO2 and RH were similar at the start of each test at 89°F, 0.22 percent and 31.6 percent, respectively.

At the end of the tests the environmental temperature was highest for VSDH at 107 °F. VSDCO had the highest level of CO2 at 31.5 percent. RH increased in VSD and VSDH to 62.5 and 66.0 percent, respectively. The high level of RH appears to have contributed to the diminished ability to reduce core body temperature (CBT). At TOD the CBT was highest for VSD (113.1 °F) and VSDH (115.3 °F) while VSDCO CBT was (105.8 °F). The time to reach TOD was longest in VSD at 91 minutes followed by VSDH at 54 minutes and VSDCO with the shortest TOD at 12 minutes. Comparing EEGs and behaviour profiles demonstrated that VSD hens spent 82 percent of the time unconscious while the VSDH and VSDCO hens were unconscious 56 percent and 65 percent of the time, respectively. It was also observed that the stress indicator of heat shock protein 70 (HSP70), for hens exposed to stressors such as heat, humidity or CO2, declined in the VSD and VSDH environments from time 0 to TOD possibly due to the duration of the unconscious state of the hens.

2) examine the effectiveness of VSD in a multi-level, commercial cage setting.

A field scale up of the process to evaluate the effectiveness of VSD, VSDH and VSDCO in a multi-tier cage system was conducted using white leghorns housed in 2-tier stair step cage system at industry densities (72 in2/hen). The environment was a force ventilated negative static pressure room sealed to prevent air exchange of any type. An inner chamber around the cages emulated the building volume per hen found in the industry.

The data collected included CO2, RH, environmental temperature profiles, CBT and HSP70. We found that VSD by itself did not result in 100 percent euthanasia of the flock with 4 percent of the hens surviving. When we added heat or CO2 to the VSD system we accomplished 100 percent mortality. The duration to TOD was no different between VSDH and VSDCO. Based upon these field studies, VSDH and VSDCO appear to be the most humane methods of depopulating large numbers of caged hens.

Practical applications of nutrigenomics in poultry nutrition Novel molecular techniques such as microarray technologies have spurred the development of the fi eld of nutrigenomics.

Using microarrays to evaluate gene responses allows us to assess the activity of thousands of genes at the same time, thus permitting a rapid measure of physiological changes. Nutrigenomics can provide a powerful tool for understanding how nutrition impacts performance, health and disease in poultry. This paper will serve as a review of current applications of Nutrigenomics in poultry nutrition.

The wealth of information obtained from nutrigenomics studies can help nutritionists and producers better understand how to feed poultry to ensure optimal health and performance.

Nutrigenomics is the study of how nutrients, forms of nutrients, and nutritional strategies impact the genome. The use of DNA microarray technology allows us to begin to understand how nutrition modulates gene expression and how this modulation relates to animal health and performance. These molecular technologies also allow for the rapid evaluation of nutritional strategies. Advancements in the area of bioinformatics have enabled investigators to decipher the functional and biological relevance of nutrigenomic data sets. Together, these technological advances are creating new opportunities in poultry research that could lead to improved animal health and production.

Gastrointestinal tract The avian gastrointestinal tract (GIT) plays a central role in the digestion of feed and absorption of nutrients. Its proper function is essential for optimal health and growth. The GIT not only includes the tissue and cells of the intestine but also the complex community of microbes it harbors. Nutrigenomics can provide a systems biology approach to understanding how nutrients influence intestinal health through interaction with gut cells and the microbiota in the intestine (which in turn can change gut cell dynamics).

Both prebiotics and probiotics can improve gut health resulting in improved feed efficiency and growth in broilers. The cellular mechanisms behind these improvements have been elucidated utilizing nutrigenomics. For example, adding mannan oligosaccharides (MOS) to broiler diets not only increases the

Nutrigenomics data suggest that the antioxidant mimics vitamin E at a transcriptional level by inducing the expression of genes involved in lipid metabolism, cell morphology and cellular oxidation.

Nutrigenomics has also been used to determine the underlying reasons why we see a production response with one nutrient form but not with another (e.g., organic versus inorganic minerals).

An even newer area of research that is increasing our knowledge about the interaction of nutrition and GIT health is microbiomics. Microbiomics uses molecular biology techniques, such as advanced DNA sequencing, to study the ecology of the GIT microbial communities. Currently this field is in its infancy and research is limited to general characterization of the unique communities present in each segment of the intestine. Eventually molecular profiling should provide the data needed to equip us to optimize the microbiome through nutrition for improved bird health and production.

intestine. For example, Brennan et al. (2011 & 2012) showed that, in both male and female birds, different forms of selenium activate transcription of different functional groups of genes, explaining why organic selenium improves reproduction over inorganic selenium.

Nutritional programming Over the past several years, researchers have begun to investigate how restricted, “programmed” nutrition during the neonatal and early-life periods can affect animals during adulthood.

Nutrigenomics can be used to explain why we sometimes see differences between nutrient forms. For example, vitamin E supplementation of broilers is known to confer antioxidant benefits and to improve meat quality and shelf life. Nutrigenomics studies have also shown that vitamin E acts a transcriptional regulator in lipid metabolism and oxidation, helping to further explain its beneficial effects. In other studies, nutrigenomics has been used to determine why different nutrients can sometimes have the same effects on physiological markers. For example, Xiao et al. (2011) showed that a commercial algae-based antioxidant

NUTRITION

In chickens, for example, more than 24 h of fasting post-hatch has been shown to have unfavorable effects on weight gain, gut health and meat quality in adult broilers. Conversely, feeding chicks posthatch diets with reduced protein levels has been shown to benefit bird growth and development throughout adulthood, even after chicks are switched to a traditional diet. Delayed access to feed posthatch has been shown to alter hepatic gene expression.

(e.g., weight gain, egg production) from whole-animal studies help us to better understand how nutrients affect animal health and production. Nutrigenomics provides a way to identify precisely which nutrients or nutrient combinations are optimal and when they should be delivered to elicit maximum benefits. Through the application of nutrigenomics, we anticipate improved poultry production economics stemming from streamlined feeding strategies, leading to improved feed efficiency and bird health.

Nutrigenomics can help us understand how nutritional programming works by revealing the gene expression patterns associated with early-life nutrition. For example, feeding 100% of the NRC recommendations (normal) for trace minerals for the first 96-h post-hatch can have positive effects on gene expression even after birds are switched to low (20% of the NRC recommendations) mineral diets. In this study, higher levels of minerals fed during the post-hatch period were shown to increase the expression of genes such as Cyclin D1, which play a key role in cell cycle regulation, a biological function essential for gut mucosal growth and repair. The expression of solute carrier proteins, a family of transporters essential for the active and passive transport of nutrients in the small intestine, were upregulated in adult birds that received the normal post-hatch diet, as was the expression of genes involved in the uptake of minerals and other nutrients. In the study by Brennan et al., there was no effect on performance. However, considering the importance of proper intestinal function and health, these changes are considered beneficial. Overall this study demonstrated that post-hatch nutrition can alter gene expression patterns longterm, which can have lifelong implications for bird health.

Commercial applications We anticipate that the application of nutrigenomics research will lead to the implementation of improved precision feeding strategies by the poultry industry.

Modification of the chicken intestinal epithelial physical barrier

Y. Guo, D. Liu and B. Zhang Faculty of the State Key Laboratory of Animal Nutrition, College of Animal Science and Technology Agricultural University, Beijing, China

46

The intestinal epithelial physical barrier is the most critical element of maintaining an intact intestinal barrier and made up of a layer of columnar epithelial cells and intercellular junctional complexes including tight junctions, adherens junctions and desmosomes.

Tight junctions (TJ), which are formed by proteins including claudins, occludin, junctional adhesion molecule and zonula occludens (ZO), are primarily responsible for the permeability of the paracellular pathway.

The function of the intestinal barrier function in poultry is evaluated by measuring intestinal permeability.

Few studies have shown the developmental profile of intestinal barrier function and tight junction proteins in the intestinal epithelium of chicks in embryonic phase or/and the early post-hatch period.

Several feed additives, including nutrients (i.e. Zn), probiotics, prebiotics, functional polysaccharide, enzymes and epidermal growth factor, were shown to regulate intestinal barrier function by modifying expression and localization of TJ proteins.

adhesion and intracellular communication, respectively. The cytoskeleton is an intricate structure of protein filaments that extends throughout the cytosol that is essential for maintaining the structure of all eukaryotic cells. Disruption of the cytoskeleton is linked to the loss of intestinal barrier integrity.

The intestinal epithelial physical barrier

Tight junctions are formed by protein dimers that span the space between adjacent cell membranes. There are over 50 proteins with well recognized roles in tight junction formation.

These proteins comprise four integral transmembrane proteins (e.g. occludin, claudins, junctional adhesion molecules (JAM) and tricellulin), and cytosolic scaffold proteins, such as zonula occludens (ZO) proteins. The extracellular domains of the transmembrane proteins form the selective barrier by hemophilic and heterophilic interactions with the adjacent cells. The intracellular domains of these transmembrane proteins interact with ZO proteins, which in turn anchor the transmembrane proteins to the perijunctional actomyosin ring. The interaction of TJ proteins with the actin cytoskeleton is vital to the maintenance of TJ structure and function. In addition, the interaction of the TJ complex with the actomyosin ring permits the cytoskeletal regulation of TJ barrier integrity. The function of occludin is not yet fully understood, but numerous studies using animals and cell cultures indicate that it is required for TJ assembly and barrier integrity in the intestinal epithelia. Occludin has been linked to

The intestinal epithelium forms the largest and most important barrier between internal and external environments of animals. The intestinal epithelial barrier is made up of a layer of columnar epithelial cells that forms the first line of defense between the intestinal lumen and inner milieu. The intestinal epithelial cells are mainly absorptive enterocytes (over 80%) but also include entero-endocrine, goblet, and Paneth cells.

The epithelium allows the absorption of nutrients while providing a physical barrier to the permeation of pro-inflammatory molecules, such as pathogens, toxins, and antigens, from the luminal environment into the mucosal tissues and circulatory system. The epithelial selective permeability includes two pathways: the transcellular and the paracellular pathway. The transcellular pathway is involved in the absorption and transport of nutrients, including sugars, amino acids, peptides, fatty acids, minerals, and vitamins. As the cell membrane is impermeable, this process is predominantly mediated by specific transport-

Injured intestinal barrier is characterized by increased intestinal permeability, which allows luminal antigenic agents (e.g., bacteria, toxins, and feed-associated antigens) to leak across the epithelium to sub-epithelial tissues, to result in inflammation, malabsorption, diarrhea, and potentially systemic diseasesâ&#x20AC;?

ers or channels located on the apical and basolateral membranes. The paracellular pathway is associated with transport in the intercellular space between the adjacent epithelial cells.

These epithelial cells are tightly bound together by intercellular junctional complexes that regulate the paracellular permeability and are crucial for the integrity of the epithelial barrier.These junctions allow the passage of fluids, electrolytes, and small macromolecules, but inhibit passage of larger molecules.

The junctional complexes consist of the tight junctions, gap junctions, adherens junctions, and desmosomes. Tight junctions are the most apical and are primarily responsible for controlling permeability of the paracellular pathway. Adherens junctions are located beneath the tight junctions and are involved in cell-cell adhesion and intracellular signaling. Both tight junctions and adherens junctions (together known as the apical junctional complex) are associated to the actin cytoskeleton. Desmosomes and gap junctions are involved in cell-cell

the regulation of intermembrane diffusion and paracellular diffusion of small molecules. The claudin proteins are considered to be the structural backbone of TJ. Claudins consist of at least 24 members in humans and mice, and each isoform shows a unique expression pattern in tissues and cell lines. In contrast to their structural similarities, claudins perform different functions and can be roughly divided into two types: those involved in barrier formation (decreasing paracellular permeability) and those in channel pores (increasing paracellular permeability).

In the intestines, claudin-1, -3, -4, -5, -8, -9, -11, and -14 can be categorized as barrier-forming claudins, while claudin-2, -7, -12, and -15 are pore-forming claudins. Several plaque proteins have been identified, including the zonula occludens (ZO) proteins, ZO-1, ZO-2, and ZO-3. Plaque proteins potentially play a central role in TJ regulation, because they can cause reorganization of the cytoskeleton. Claudin-1, claudin-2 , claudin-3, claudin-5, claudin-16, ZO-1, ZO -2 and occludin are reported in poultry.

b) Bacterial translocation The disruption in barrier functions was associated with viral and bacterial translocation across the epithelial monolayers.

Bacterial translocation is defined as the passage of viable bacteria from the intestinal tract through the epithelial mucosa into extra-intestinal organs. Impaired mucosal surfaces can increase vulnerability of the intestinal epithelium with an augmented risk of bacterial and viral penetration, or bacterial overgrowth in the in the intestine. c) Plasma LPS concentrations

TJ are not static barriers but highly dynamic structures that are constantly being remodeled due to interactions with external stimuli, such as food residues and pathogenic and commensal bacteria. Regulation of the assembly, disassembly, and maintenance of TJ structure is influenced by various physiological and pathological stimuli. Signaling pathways involved in TJ regulation, and interactions between transmembrane proteins and the actomyosin ring are controlled by several signaling proteins, including protein kinase C (PKC), mitogen-activated protein kinases (MAPK), myosin light chain kinase (MLCK), and the Rho family of small GTPases.

Assessment of the epithelial physical barrier function in poultry a) Intestinal permeability Intestinal permeability is defined as the non-mediated diffusion of large (i.e., molecular weight >150 Da), normally restricted molecules from the intestinal lumen to the blood. The primary means of determining intestinal permeability in humans or animals is by measuring the passage of high molecular weight probes across the gastrointestinal tract barrier. In humans, this involves ingestion of a solution containing nontoxic, non-metabolizable substances (such as sucrose, lactulose, sucralose) and assessing their excretion in the urine. The appearance of probes in the urine indicates loss of barrier function in the gastrointestinal tract. However, that method is unsuitable for poultry because of the mixture of urine and feces. In animal models including poultry, intestinal permeability is usually determined by infusing fluorescent probes, such as fluoroisothiocyanate (FITC)-dextrans, into the intestinal area of interest and measuring plasma concentrations over time. The probe horseradish peroxidase was also reported.The Ex vivo Ussing chamber is the most sensitive to test the intestinal permeability by measuring transepithelial electrical resistance (TER), as it reflects the opening of the tight junctions between epithelial cells and the paracellular permeability of the intestinal mucosa.

48

LPS is a highly pathogenic component of the walls of gram negative bacteria and is found in the intestinal tract in high concentration. Its presence in the portal blood of animal models indicates passage from the intestinal lumen to the circulation.

Increased LPS concentration in the systemic circulation likely indicates severe intestinal barrier dysfunction.

Development of the epithelial physical barrier Kawasaki et al. (1998) determined the developmental expression of occludin in the gastrointestinal tract of 3- to 21-day-old chick embryos and reported that occludin mRNA was first detected by RTâ&#x20AC;&#x201C;PCR in the chick embryo on day 3 of incubation, by northern blot analysis on day 4, and by western blot analysis on day 5, suggesting that synthesis of occludin begins in the chick embryo at a very early stage of development. The immune-histochemical assay revealed that occludin began to be weakly expressed only along the apical surface of the gastrointestinal epithelium of the 4-day-old chick embryo. As the embryo developed, the immunoreactivity gradually became stronger and formed more complex networks near the apical surface, which indicated that the developmental expression of occludin in the gastrointestinal tract is closely correlated with the morphological as well as functional development of the tight junction. Roberts et al. (2005) reported that the small intestinal epithelial barrier function of broiler chicks hasnâ&#x20AC;&#x2122;t developed well at hatching, and the jejunal TER increased more than 3-folds and the ileal TER increased one-fold during d2 to d11 of age.

Jejunal occludin expression increased linearly with age, but did not reach a plateau by d11, even though no effects of age on ileal occludin or on zonula occludens-2 expression were observed. Their work shows that the epithelial barrier function of the ileum is not fully developed in broiler chicks until later than d 14 of age for the ileum. More research are required to develop nutritional solutions beneficial for the small intestinal barrier function development and gut health.

mentation reduced gut lesion scores and the intestinal permeability and increased expression of ZO-1 and occludin in mammals. Zn deprivation induced a decrease of TER and altered tight and adherens junctions. Zhang et al. (2012) reported that Zn (as ZnSO4) up-regulated occludin and claudin-1 mRNA expression in the ileum and tended to reduce plasma endotoxin levels in the chickens challenged with Salmonella Typhimurium, and indicated that regulation of occludin and claudin-1 expression by Zn could be involved in ameliorating the increased intestinal permeability induced by Salmonella Typhimurium challenge. Hu et al. (2013) showed that supplemental ZnO or ZnSO4 did not affect ileal and colonic barrier function and intestinal microflora in broiler chickens; however supplemental 60 mg of Zn/kg as ZnO-MMT (zinc oxide-montmorillonite hybrid) increased colonic TER values, and reduced colonic probe mannitol permeability as well as ileal or colonic inulin permeability of the chickens.

claudin-1 and occludin, and the increased goblet cell numbers and sIgA level in the jejunum of the broiler chickens. Parson et al. (2014) reported that in chickens, dietary supplementation with soluble non-starch polysaccharide (NSP) plantain NSP reduced invasion by S.Typhimurium, as reflected by viable bacterial counts in splenic tissue, and plantain NSP inhibited adhesion of S.Typhimurium to a porcine epithelial cell-line and to primary chick caecal crypts in vitro. d) Enzymes

b) Probiotics and Prebiotics

Clostridium perfringens challenge increased the intestinal lesion score and also resulted in passive transcellular permeability and higher plasma endotoxin in the chickens, and dietary addition of xylanase or enzyme complex containing xylanase, glucanase and mannanase could alleviate the alteration caused by C. perfringens infection, indicating that dietary enzyme supplementation could benefit for gut barrier integrity of the C. perfringens-challenged chickens.

In the study by Rajput et al. (2013), compared to treatments with Saccharomyces boulardii and Bacillus subtilis B10, the tight junctions of jejunum and ileum of broilers were comparatively loose in the control group, and both Saccharomyces boulardii and Bacillus subtilis B10 improved the epithelial tight junctions through increasing occludin, claudin-2, and claudin-3 mRNA expression levels in the intestine of the broilers. CAO et al. (2014) reported that L. fermentum 1.2029 was able to ameliorate the severity of necrotic enteritis lesions and inflammation and improved the epithelial barrier through increasing claudin-1 and occludin levels in the necrotic enteritis-infected chickens.

Lysozyme as a natural antimicrobial protein occurs in a number of animal secretions and is considered an important component of the innate immune system. The addition of exogenous lysozyme significantly reduced the concentration of Clostridium perfringens in the ileum and the intestinal lesion scores, and inhibited the overgrowth of E. coli and Lactobacillus in the ileum and intestinal bacteria translocation to the spleen of chickens challenged with Clostridium perfringens, suggesting that exogenous lysozyme could be used to improve the intestinal barrier function of chickens.

Heat stress not only negatively affected the intestinal microbiota balance, also decreased the jejunal TER and increased the jejunal paracellular permeability of FITC-dextrans, and which was correlated the down-regulated jejunal protein levels of occludin and ZO-1 in the broilers. Supplemental probiotic mixture containing Bacillus licheniformis, Bacillus subtilis and Lactobacillus plantarum increased the jejunal protein level of occludin in the broilers. That indicated that dietary addition of the probiotic mixture was effective in partially ameliorating intestinal barrier dysfunction induced by heat stress in broilers.

Song et al. (2013) also reported that supplemental cello-oligosaccharide, a functional oligosaccharide obtained from plant cellulose, increased the jejunal villus height and villus height to crypt depth ratio, as well as decreased jejunal paracellular permeability of FITC- dextran in the broiler chickens. c) Functional polysaccharides β-1,3/1,6-glucan from Saccharomyces cerevisiae has beneficial effects on both the innate and acquired immune systems, and clearance of pathogens such as Salmonella, Escherichia coli and coccidiosis in broiler chickens. The work of Shao et al. (2014) showed that dietary β-1,3/1,6-glucan supplementation could attenuate the intestinal mucosal barrier impairment in the broiler chickens challenged with Salmonella Typhimurium, and that could be related to the increased mRNA expression of

e) Epidermal growth factor (EGF) EGF is a small amino acid peptide with a broad range of bioactivities on the intestinal epithelium, including the stimulation of cellular proliferation, differentiation, and intestinal maturation.

In chickens, EGF reduced jejunal C. jejuni colonization and alleviated the dissemination of C. jejuni to the liver and spleen.

In the in vitro study, the pretreatment with EGF abolished the C. jejuni-induced intestinal epithelial abnormalities, such as disruption of tight junctional claudin-4, increasing of transepithelial permeability and the translocation of non-invasive Escherichia coli C25. f) Others Other dietary factors such as threonine, glutamine, and flavonoids were also reported to regulate intestinal epithelial barrier in animals or cell lines in vitro, but few reports in poultry were found. More nutritional solutions to improve intestinal barrier function and the underlying molecular mechanisms are needed to be investigated.

Comparison of wheat and maize-based diets on growth of broilers Maize and wheat are a major source of energy in broiler diets.

Generally, wheat-based diets are offered to broiler chickens in Europe, Australia and New Zealand while maize-based diets are widely used in the US and Asia.

Studies have demonstrated that dietary cereal source have a significant influence on bird performance however the type of cereal used has received little attention as a factor affecting chicken meat quality. Del Puerto et al. (2016) reported that dietary cereals may affect pH and colour of meat.

Moreover, Kennedy et al. (2005) have shown that while meat from birds fed maize-based diets may benefit from dietary vitamin E supplementation to improve the sensory value of meat, there was no advantage in supplementing wheat-based diets.

This observation suggests a gap in the meat quality between the two cereal types. Therefore, the objective of this study was to measure some meat quality and growth performance parameters of broiler chickens offered diets where maize or wheat provided the major energy source.

Materials and methods All procedures used in this study were approved by the Animal Ethics Committee of University of Sydney. Experimental birds were housed in battery cages. Broilers (Ross 308, male) were placed on a common wheat-based standard starter diet until day 10. From 10 to 17 days and from 18 to 38 days, broilers were offered grower and finisher diets respectively which

were based on either maize or wheat as a principle source of carbohydrate, and satisfied all nutrient requirements as suggested by the breeder manual. All experimental diets provided similar calculated metabolizable energy (ME kcal/kg) and crude protein (%).

Energy levels were adjusted with soybean oil and digestible amino acid levels with soybean meal, canola meal and synthetic amino acids. Exogenous enzymes were not included.

Chicks had ad libitum access to water and feed. Average individual body weights (BW) and average daily gain (ADG), and cage average daily feed intake (ADFI) and feed conversion ratio (FCR) were recorded on a weekly interval. The FCR values were corrected for the body weight of any bird that died during the course of the experiment.

At 38 days of age, birds were killed according to the recommendations for euthanasia of experimental animals. Meat quality was determined on 1 bird per cage. Drip loss was determined by the weight difference of suspended Pectoralis muscle samples stored at 4°C at 0, 24, 48 & 72 h post-slaughter. Meat colour change was determined daily over 7 days using the CIELAB method for lightness (L*), redness (a*) and yellowness (b*) in the Pectoralis muscle using a Minolta Lab CR-10 colourimeter.

The pH was determined at 0 and 1 day of post mortem in the Pectoralis muscle using a glass electrode (TPS ionode) attached to a portable pH meter (TPS LC80A pH-mv-TEMP), which is temperature compensated. Shear force value of Pectoralis muscle was determined with a Warner Bratzler Shear

Data were analysed using the generalised linear model procedure of SAS. Meat colour data were analysed by repeated measures using the mixed procedure of SAS. The experimental units were pooled cage means for growth performance and 1 bird per cage for meat quality. Data are presented as least squared means Âą standard error of the mean (SEM). Differences were considered significant at P < 0.05.

Results and discussion The effects of feeding wheat and maize-based diets on growth performance are presented in Table 1 and meat quality is presented in Figure 1 & 2 and Table 2. Dietary cereals had no effect on body weight (BW), average daily gain (ADG), feed conversion ratio (FCR), and average daily feed intake (ADFI) of broilers chicken from 10-17 and 17-24 d of age. Similarly, BW and ADG of birds from 25 - 38 days of age were not influenced by wheat or maize-based diet, but the birds fed on maize-based finisher diet had lower FCR (P<0.001) and ADFI (P<0.001) compared to those offered wheat-based diets. These outcomes are in agreement with Peng et al. (2003) who stated that a maize-based diet significantly improved FCR when compared with a wheat-based diet. There was no significant effect of dietary cereals type on mortality rate of broiler chicken over the entire growth period.

The breast meat of broilers offered the maize-based diet had a higher drip loss rate than the wheat-based diet (P<0.05; Figure 1). These results are confirmed by Ao and Choct (2004) who reported that wheat-based diet fed group of birds had a lower drip loss value than the maize. An increase in drip loss in the maize-fed group also agrees with the observations of Kennedy et al. (2005) who observed an improvement in the eating quality of maize-fed, but not wheat-fed chicken meat when supplemented with vitamin E. In the present study, meat from the birds fed the wheat-based diet had (P < 0.001) higher lightness (L*) value (Figure 2), which might be due to a lack of pigments otherwise present in maize. Similarly, wheat-based diet fed birds produced meat with (P < 0.05) a higher redness (a*) value (Figure 2). These findings are in disagreement with Smith et al. (2002) who stated that wheat-based diets decreased redness (a*) value compared to maize-based diets. In contrast, the yellowness (b*) value (Figure 2) of meat from maize-based diet was (P < 0.001) higher than the meat from wheat-fed birds, which might be because of pigments (carotene and xanthophylls) present in yellow maize.

In this study, the shear force value of breast meat was not (P > 0.05) influenced by dietary wheat or maize. These results are in disagreement with Lyon et al., (2003) who got significantly higher shear force value in meat from wheat-based diet compared with maize diet. Similarly, dietary cereals had no

“A total of 72, 10-day old Ross 308 broilers male chicks were randomly allocated to 2 dietary treatments with 6 birds per cage and 6 replications in each treatment. Experimental diets were formulated to be iso-calorific and iso-nitrogenous. Body weight (BW), average daily feed intake (ADFI), average daily gain (ADG), feed conversion ratio (FCR) from 10-38 d, and pectoralis muscle drip loss rate, colour, temperature, pH, and shear force at 38 d were evaluated”

Conclusion To our knowledge, there has been little research conducted to evaluate the response of meat quality to broiler diets based on maize or wheat. In this study, birds fed wheat-based diets had poorer feed efficiency and higher feed intake in the final week (from 25-38 days of age) only.

Meat from maize-based diets was more yellow whereas birds offered a wheat-based diet had more red and lighter-coloured meat and a higher water holding capacity. The results of this study indicate that variations in dietary cereal use as a major carbohydrate may be related to differences in meat quality properties. Further evidence is merited exploring the evidence and explanation for variation in meat quality between diets based on these major cereals. significant effects on the pH value of breast meat. These findings are supported by Perlo et al. (2010); Osek et al. (2010); Garcia et al. (2013) who did not notice any significant effect of dietary cereals on pH value of broiler chicken meat.

VETERINARY SCIENCE

Investigation of nutritional diseases at the veterinary diagnostic laboratory Current literature reviews of nutritional diseases in poultry indicate that the occurrence is generally less common compared to reports of fi fty years ago. This may be a result of improvements in feed formulations, mixing procedures and feed distribution.

Initial approach ŠVet Clinic Tyrus

Investigation of the flock by the production manager or company veterinarian as quickly as possible is vital; however, upon early recognition of the condition a full necropsy to rule out infectious disease is important.

What should you do if you immediately suspect a feed issue contributing to severe flock signs?

If there is first hand evidence of a feed deficiency or toxicosis one should and replace feed may be prior to contacting the veterinary diagnostic lab.

This will require having extra feed bins on the farm. The response of the flock to feed replacement can be interpreted along with testing on feed, water and birds, to confirm the diagnosis.

The producer or veterinarian should collect 1-2 lb of feed and ½ gallon of drinking water as samples representative of what the flock received.

Regardless issues with feed formulation or nutrient absorption should always be a concern when flocks are experiencing reduced growth, lameness, poor feathering, dehydration, reduced egg production or poor shell quality. Perhaps most nutritional issues are corrected early in the field as part of day-to-day flock management, especially since young, growing birds will be affected the worst by reduced nutrients.

Here below the role the veterinary diagnostic laboratory can play in helping to confirm nutritional disease in a flock has been described.

Types of disorders

For the generally small number of feed-related issues, the case is usually submitted with one of the two histories: 1) immediate change in flock behavior, e.g., decreased feed consumption, mortality, paralysis, and 2) a chronic, insidious or predictable condition that has been observed in successive flocks, e.g., feather loss, reduced egg production, lameness.

- veterinary science -

What should you do if you suspect chronic nutritional disease or toxicosis?

There will be situations where you observe chronic, insidious clinical signs that occur in successive flocks. A recurring production problem can be tackled with more thorough investigation and sample collection. Keep detailed production and feed records to be shared with the nutritionist, veterinarian and laboratory diagnostician.

Feed and water samples should be collected and refrigerated 1-2 weeks prior to the predicted onset of the clinical signs and birds should be submitted to the diagnostic laboratory for full diagnostic workup including histopathology. Later, when the particular clinical signs are observed, similar feed and water samples should be collected, and birds should be submitted for additional diagnostic workup. It is paramount to rule out infectious disease as the primary cause of the clinical signs. Once infection has been ruled out one can investigate for nutrient deficiency or toxins in feed and water as well as compare

VETERINARY SCIENCE

necropsy findings before and after onset of clinical signs. Keep in mind that a thorough investigation requires additional feed, water and tissue analyses that can triple or quadruple the cost of the necropsy.

What does a pathologist do with the birds and samples submitted to the veterinary diagnostic laboratory?

The vet pathologist generally prefers to receive whole, intact birds for necropsy within 24-36 hours of death or less, although this cannot always be done with large birds or concerns about shipping costs and delays in transit. The pathologist will assess the following items (costs increase as one progresses from 1-8):

Key Examples of feed-related deficiency or toxicosis observed in the last ten years 1. Rickets - Soft bones occurring in young birds is referred to as rickets. This disorder is usually caused by abnormal Ca/P ratios in the ration, low vitamin D3 levels in the ration, or intestinal malabsorption associated with enteric diseases. The birds are often recumbent, but bright and alert with extremely pliable beaks and long bones.

VETERINARY SCIENCE

In cases of rickets a complete feed analysis for deficiency of protein, calcium, phosphorus, vitamin D3, manganese and choline is recommended.

2. Osteomalacia - Also known as cage layer fatigue in laying hens, this nutritional disease is characterized by decreased mineral in bone resulting in soft, pliable bones including the beak, curved keel bone and beading of the ribs at the costochondral junction. High-producing hens maintained in cages can show paralysis during the period of peak egg production.

Depletion of calcium in the medullary bone of the long bones is seen in caged layers; perhaps reduced activity/exercise is a predisposing factor. Affected birds can be found on their sides in the back of the cage. At the time of initial paralysis, birds can appear healthy and will have a shelled egg in the oviduct.

Death occurs from starvation or dehydration, a failure of the birds to reach the feet or water. A high incidence of cage layer fatigue can be prevented if pullets receive a high calcium diet (minimum of 3.5% calcium) at least two weeks prior to the first oviposition. Older caged layers are also quite susceptible to bone breakage, particularly during transport to processing. The condition results in reduced mineral in bone (soft bones-osteomalacia) or bone with normal mineral content, but decreased in amount of total bone (osteoporosis).

4. Vitamin E (alpha tocopherol)/Selenium deficiency - Also known as crazy chick disease or cherry brain, this disease is caused by deficiency of vitamin E. This deficiency is usually diagnosed in young chicks and turkey poults, but can affect a wide variety of birds. Vitamin E is a natural antioxidant and is need for maintenance of brain tissue and embryo development, especially in growing birds. Selenium is needed for vitamin E metabolism. Three conditions associated with vitamin E deficiency are encephalomalacia, exudative diathesis, and muscular dystrophy/degeneration; these all are related to oxidative damage to cells or blood vessels.

3. Chondrodysplasia - This condition, observed in both turkey and broiler chickens, is characterized by failure of blood vessels to completely invade the growth plate of long bones, resulting in retained cartilage cores at the growth plate. There is a strong heritability factor with this condition, but it can, especially in broiler chickens, be exacerbated by rapid growth rate and reduced Vitamin D3 in the ration.

5. Fatty liver syndrome (hepatic lipidosis) - Fatty liver is caused by an imbalance of energy (positive energy gain) and protein intake. Fatty liver is observed most often in caged laying hens and occasionally in breeder turkey hens. Caged layers are particularly prone to fatty liver because of minimal exercise accompanied by high calorie intake; however, more cases of fatty liver in floor-raised brown egg layers have been diagnosed as well. The liver is enlarged, pale orange, soft, friable and is easily fractured. Rupture of the fatty liver with hemorrhage into the abdominal cavity is a common cause of death in laying hens. Treatment with choline chloride, vitamin K, biotin, and vitamin E in the feed for two weeks has been used to control mortality with varying results. Prevention is by use of an adequate diet with proper energy and protein levels.

6. Aortic rupture - This condition occurs sporadically in 14-15-week-old male turkeys or older, often appearing as spiking mortality. The toms are often found dead with blood exuding from mouth and nostrils. For years this condition has been attributed to both heritability and vascular hypertension, the latter which could be induced experimentally by severe copper deficiency.

7. Visceral gout/urolithiasis - Gout/urolithiasis is a condition very commonly seen in older layer flocks and is related to kidney failure. On occasion, gout can be a very significant part of flock mortality, sometimes as high as 0.5% per week, but is often an insignificant cause of low-grade mortality. Kidneys can be damaged by low phosphorus diets at any age, water deprivation at housing, high vitamin D3 in the ration, or excessive calcium before sexual maturity (15 to 16 weeks). Infectious bronchitis virus can cause renal damage and is often associated with urolithiasis.

8. Gizzard erosions - Erosions and ulcers of the koilin lining of gizzard in young poultry can cause inappetence as well as death from blood loss in severe cases. Koilin damage has been associated with adenovirus, reovirus, caustic chemicals, mycotoxins (suspected), and nutritional causes such as biogenic amines (gizzerosine, histidine) produced by rancid or spoiled fish and animal by products, especially fat.

(right). Specific etiologies were not identified in these cases, although feed toxins were considered.

9. Inadequate vitamin K supplmentation in feed - Increased dietary supplements can be essential during particular stages of growth or for under treatment condition. Vitamin K is a co-factor in the blood coagulation cascade. Vitamin K is generally adequate in feed, but should be supplemented when pullets are beak trimmed by hot blade.

10. Ionophore toxicosis - Polyether ionophores facilitate transport of divalent cations across cell membranes to interfere with osmoregulation, resulting in cell rupture. Toxicosis caused by ionophores is relatively common in poultry, because these compounds are commonly administered for the prevention and treatment of coccidiosis and are subject to overdosing and mixing errors. Additionally, these ionophores can interact with certain medications, such as sulfonamides, to cause toxicosis signs when the ionophore concentration in the feed is normal.

11. Sodium toxicosis - This condition occurs intermittently and clinical signs can result from elevated Na concentration in either feed or water. Properly formulating sodium concentration in the ration can be a challenge if there is high salinity in soil or drinking water. In general Na concentrations of Na in feed > 0.85% (8500 ppm) and in water > 0.4% (4000 ppm) can produce heart failure, pulmonary edema and ascites in young chicks and poults. In cases of suspected sodium toxicosis the Na concentrations in both feed and water should be determined. Young chicks or poults developing cardiomyopathy (â&#x20AC;&#x153;roundheartâ&#x20AC;?) will be more susceptible to pulmonary edema and ascites even under normal sodium concentrations in feed and water. Rations that are low in sodium can cause abrupt decrease in feed consumption and dehydration in chicks and poults, with similar changes and drops in egg production in mature layers.

In summary, the diagnosis of nutrient deficiency or toxicosis and supplement toxicosis in a poultry flock often requires close examination of the flock, detailed record keeping and thorough diagnostic examination by the veterinarian and/or veterinary pathologist (veterinary diagnostic laboratory). This diagnosis can be expedited by thoughtful collection and storage of feed and water samples along with careful assessment of how costs should be directed for analysis of particular nutrients or toxins.

The chance of a successful diagnosis as well as treatment/prevention is enhanced by regular communication between producer, production manager, veterinarian, nutritionist and veterinary pathologist.

VETERINARY SCIENCE

A new era of veterinary oversight In June of 2015 The Food and Drug Administration announced their fi nal rule on Veterinary Feed Directives. This rule is intended to improve how antibiotics are used in agriculture by bringing them under veterinary oversight. This rule also prohibits production uses of antibiotics, limiting use to therapy or prevention.

Producers have several responsibilities as well.

They must agree to only use the medicated feed for the animals, which it was written for. The producer must not use the medicated feed past the expiration date listed on the VFD. Records need to be maintained for two years.

Most of the antibiotics used in poultry medicine will fall under this new rule. There are a few exceptions: dewormers, Ionophores and bacitracin.

©cookfamilyfarm.com

In 2017 water based antibiotics fell under this rule. Antibiotics used in the feed must be used ONLY as their label lists. There is no EXTRA LABEL use of feed medications. The labels for most of the feed antibiotics used on poultry farms are very limited. Good diagnostics are the key to proving the correct antibiotic is being used.

As of January 1, 2016 most antibiotics used in animal feed needed a VFD issued by a licensed veterinarian. VFD stands for Veterinary Feed Directive.

This is a fancy way of saying in order for a feed mill to make feed containing most antibiotics they will need a document from a licensed veterinarian before making that feed. These feed medications need to be used only as the label indicates, no exceptions.

In order for a veterinarian to write a VFD they first need to be licensed in that State. The next big requirement is to make sure a VCPR exists.

VCPR stand for Veterinarian – Client – Patient – Relationship. This means that the issuing veterinarian needs to have a good enough relationship where they fully understand the animals, facility and diseases well enough that they assume responsibility for their treatment. They must also be available for any follow up care.

- veterinary science -

There is a long list of items that must be listed on the VFD form. Licensed poultry veterinarians will be aware of these requirements and write their VFDs to meet these requirements. The veterinarian is responsible for writing the VFD. Some drug manufacturers have developed their own forms and/or electronic reporting options.

It is very important to all producers to develop a relationship with a veterinarian in advance of needing a VFD. This way when you have an emergency you won’t need a farm visit immediately prior to running medications.

The other part of the rule is that water medications will transition from over the counter (OTC) status to prescription status. This means that farms will need to work with a veterinarian in order to use water medications. Each veterinarian will handle this process slightly differently. The producer will have to track their usage and inventory of medication. They will also have to follow the directions or protocols provided to them by their veterinarian.

Relax: the group laying nest for broiler breeders

Easier for you, easier for the birds.

For modern and successful broiler breeder management, Big Dutchman offers tailor-made concepts, the required expertise and the necessary equipment. Our tried and tested Relax group laying nest with a divided roof and a nest locking mechanism is just one example. | High nest acceptance due to optimum entrance height | Rapid and easy monitoring of the nest and the egg belt with the help of the divided and very light nest roof | Optimum hygiene and cleaning owing to the clever, wood-free nest design | Reduced egg contact thanks to an egg belt with triangular holes | Highest egg quality as a result of short rolling-off distances and gentle transport of the eggs
