Petfood technology in action – A report from an ‘open house’ held at Wenger Petfood Technology

Our April edition sees a report by Joe Kearns, the editor of International Petfood magazine and long-time Wenger Manufacturing associate, who attended an open house at the company’s newly renovated Technical Center in Sabetha, Kansas, USA. The event, titled ‘Production of Petfoods of the Future Now’, centred on demonstrations and discussions on an advanced version of the Thermal Twin Screw Extruder. Participants were allowed to spend the day discussing and observing the production of petfoods with this advanced technology. To read more, go to:

Petfood production troubleshooting Part 4 – Dryers

Part 4 of the ongoing petfood production troubleshooting series sees Joe Kearns tackle the subject of dryers. According to Mr Kearns, the dryer is without a doubt one of the machines in the system which greatly impacts the bottom line. How? Water is the reason, as products are sold with a max water percentage on the labels, so it is the lowest cost ingredient and one that should be watched closely. Mr Kearns also explains how there are many different dryer styles with

vertical and horizontal being the predominate designs, adding that in either case, the benchmark today is to have a variation in moisture out of the dryer at about 0.5 percent. To read more, go to:

Ren’s Pets’ donation to support pets in Ukraine

The benefits of supplemental essential fatty acids for the health of the horse We hear so much about essential fats in our diets, but those of our companion animals are just as important as I discussed for cats and dogs in our April issue. This is very true regarding equine nutrition and receiving much interest scientifically in many countries. It is becoming very clear that essential fatty acids serve a major role in overall equine health, and when horses consume fresh pasture, it is likely they are meeting their requirements to a great extent. It is, however, possible that supplementation above (minimum) requirements may confer further benefits. Horses cannot synthesise long chain polyunsaturated of the omega-3 family such as EPA (eicosopentaenoic) and DHA (docosohexaenoic) efficiently from linolenic acid usually found in flaxseed (linseed) oil. Dried forage loses much of its essential fatty acid levels, and often oils are added to balancing feeds and concentrate pellets mainly as oil seeds that are also typically high in omega-6 fatty acids. These however can negate the assimilation of omega-3 fatty acids. It is believed that consumption of a diet rich in the omega-3 oils will result in a greater ratio of omega-3s in the body (and in particular the lipid membranes of cells), which will offer benefits to horses such as anti-inflammatory properties. It is very important to obtain a correct balance between the omega-3: omega-6 dietary ratio for the horse to obtain the optimum pro-inflammatory and antiinflammatory pathways and immune function. Indeed, sperm quality can be indicative of a good omega-3 fatty acid enriched diet in the horse. Research has reported an increase in daily sperm output when stallions were fed marine-sourced (fish) omega-3 oils. Other studies have shown that when supplemented with fish oil, equine red blood cells have higher ratios of omega-3s, which may be beneficial to oxygen transport and platelet function. Fish oil supplementation was also shown to increase stride length, which researchers concluded was a result of decreased inflammation and stiffness within the joints. Another study offered supplemental omega-3s to older horses with arthritis and found decreased inflammatory derived compounds within their joint fluids. Laminitis (The disease process involving a breakdown of the bond between the hoof wall and the distal phalanx, commonly called the

coffin bone, pedal bone, or third phalanx) can be markedly improved with essential fatty acid supplementation. Likewise, joint and leg swelling (oedema) can be reduced in horses. Hair coat quality, dryness, and skin condition (dry scabbing) & sheen is greatly improved. Another attribute is the potential to elevate retinal condition in the eye as essential omega-3 fatty acids can sustain retinal ultra-morphology and address capillary defects.

Important improvements

The horse is a naturally stressed animal, its survival initially depending on its ability to flee. Its innate anxiety multiplies the potential sources of stress, even though each horse feels and reacts differently to stress. In relation to reduced stress: heart rate, respiration (breathing rate) body temperature, oral, rectal measurements show important and positive responses with additional omega-3 in diets. Improvements in cognition, memory, alertness, and general behaviour would also be important to record in association with enriching equine diets with omega-3 oils. For specific omega-3 supplementation, several marine-derived products such as fish oils and marine algal oils are being promoted with the latter increasingly used in balancer supplements and premixes. Fish oil has direct sources of DHA and EPA, so the benefits are more readily conferred to the body. As a point of comparison, fish oil has a ratio of 6:1, omega-3 to omega-6. Because DHA and EPA are found predominantly in fish and other aquatic life, they are sometimes referred to as ‘marine omega-3s’. Algal oil is an effective alternative or complementary addition and research is being advanced to evaluate novel products from a variety of sources that are more sustainable. The metabolism of horses will vary with age, nutritional and disease status as well as their role in society. Working horses on farms, breeding animals, racing horses, equestrian event horses and our companion ponies and horses will all have varying needs. Fats in the diet will provide energy but also vital functional roles. Essential fatty acids in oils are therefore important to maintain health, stamina, and welfare of our equine friends. 8 | May 2022 - International Petfood


anadian pet retailer Ren’s Pets announces its donation of CA$20,000 (CA$1 + US$0.77) to support pets impacted by the war in Ukraine and was delivered to Animal Food Bank, a non-profit organisation working to support pets in Ukraine. “As a company extremely passionate about pets, we wanted to help and show our support for those pets impacted by the conflict in Ukraine,” says Ren’s Pets CEO Scott Arsenault. “Our stores have been collecting donations from our very generous customers for this cause, and the amount donated has been absolutely extraordinary. We’re so thankful to our customers who have shown so much love, care, and support for Ukraine.” Chiming in, Animal Food Bank founder Nicole Frey says they were “honoured” to have been chosen by Ren’s Pets as a partner to distribute the donations that were taken from customers of Ren’s Pets. Several customers of different stores won pet gift baskets given out by Ren’s Pets for making a donation to support Ukraine. “This work is of the utmost urgency and importance and we, completely volunteer operated and non-funded, could not do this without amazing partners like Ren’s Pets,” Ms Frey adds. “We are so thankful for our collaboration with PIJAC Canada that led to this amazing initiative.” Animal Food Bank was founded in 2019 with the aim of feeding pets in need and working to address the reasons for petfood insecurity. As of April 23, has raised a total of CAS$50,922.93 that can be donated. “Learning how the Animal Food Bank is distributing funds into Ukraine has been so enlightening, to see how they’re caring for pets that have been affected,” continues Larissa Wasyliw, VP of Ecommerce & Marketing at Ren’s Pets. Ren’s Pets have also donated CA$50,000 to the Canadian Red Cross Ukraine Humanitarian Crisis Appeal alongside pet retailer Mondou’s donation of CA$100,000. Both companies are owned by Legault Group and total a donation of CA$150,000 to pets in need.


Marel acquires Wenger Manufacturing


escribed by the Icelandic company as being “a strategic platform investment into new and attractive growth markets,” Marel has agreed to acquire American food production machine fabricators Wenger Manufacturing. A long-standing, extrusion-focused company, Wenger Manufacturing was first established in Sabetha, Kansas in the USA in 1935 by Joe and Lou Wenger. Today, it has 500 employees and is a global brand, which is highly recognised and respected for its innovations in livestock feed production across the world with a particular focus on aquatic feeds and petfoods. Over the decades Wenger Manufacturing has introduced many breakthrough technologies in extrusion processing and has also influenced the development of similar companies and industry sectors. Marel started life in Iceland with a fishing industry mission of becoming a global leader in fish. Then, with time, it moved to include meat industry activities and in the 1960s changed its mission statement to become what it now calls a ‘global food player.’ In 2021 Marel formally established a business development division focused on petfood and plant-based proteins. The company made the US$540 million total investment in the acquisition while estimating the end market that Wenger sells into having a value of approximately US$2 billion with annual growth running at between four-to-six percent. The rationale for the acquisition is based on Wenger’s strong end markets, extensive offering around extrusion technology - which will complement Marel’s global reach and digital platforms. These online portals look set to be employed for new and attractive markets such as plant-based proteins, aquafeed and petfood, which require further processing, packaging, labelling, marketing and distribution. “Wenger Manufacturing makes a strong strategic fit with an extensive product offering that includes equipment for extrusion, drying and power heating,” adds Arni Sigurdsson, chief strategy Officer and EVP of Marel’s Strategic Business Units. It will support the fourth pillar focus the Marel company has for new attractive end markets and make the company a more balanced business model when it is incorporated into its global reach and digital platform. Transaction highlights & timeline Marel has agreed to acquire Wenger Manufacturing LLC., including all relevant business activities of the group. The total investment for the acquisition is US$540 million. Thereof, US$530 million is the purchase price on a cash and debtfree basis (enterprise value). The remaining US$10 million is a combination of a contribution to a not-for-profit private foundation, to continue the legacy of Wenger and its meaningful impact on the community, as well as Marel shares for Wenger employees. The purchase price will be paid with cash at hand and existing credit facilities. Discussion with selling shareholders regarding partial consideration in Marel shares is ongoing and will be concluded prior to closing. The transaction will also result in expected tax benefits of US$60-70 million and the adjusted transaction multiple corresponds to around 14x EV/EBITDA. The acquisition will be financed through Marel’s strong balance

sheet and existing credit facilities. To preserve operational headroom, Marel has signed a EUR150 million bridge facility from BNP Paribas Fortis SA/NV. Assuming a full cash payment, pro-forma leverage following completion of the acquisition is estimated to be around 3x net debt/EBITDA, compared to Marel’s targeted capital structure of 2-3x net debt/EBITDA. The closing of the acquisition is subject to customary closing conditions, including anti-trust and shareholder approval of Wenger, which is expected to take place during Q2 2022. “We are thrilled to join forces with the great team in Wenger with whom we have a strong strategic and cultural fit. Wenger’s passion for innovation and commitment to high-quality solutions, in addition to their excellent customer focus and talent management, are the key attributes Marel is proud to partner with,” states Arni Oddur Thordarson, CEO of Marel. “Wenger is a true leader in its field of providing solutions and services to the petfood industry and aquafeed industries and has in recent years made its mark on the fast-growing plant-based protein consumer market with best-in-class solutions positioned right in the centre point of the value chain,” he adds. “The Wenger acquisition is in line with our vison of a world where food is produced sustainably and affordably. Throughout the years, Marel has gradually expanded its playing field. This platform acquisition will add the fourth business segment to our business model, in addition to the poultry, meat and fish segments. “On a proforma basis, the new segment will account for around 10 percent of revenues and 12 percent of combined EBITDA. We see immediate opportunities for growth and value creation by leveraging Marel’s global reach and digital platforms in Wenger’s sizable addressable markets. The two companies have complementary technologies and a product portfolio that will accelerate the journey to become full-line providers in the respective fields. “Marel has a strong financial position to pursue future growth avenues and a proven track record in driving long-term value creation. I am confident Marel will be a good steward for the Wenger business, its talented team and continued local community engagement, and we remain committed to our continued future success,” Arni Oddur Thordarson concludes. An innovative, responsive partner “Wenger has a long history as an innovative, responsive partner to our customers. The relationships we have built, and the incredible character of our people are central to this. Our long-standing customers worldwide are looking for a trusted partner and local support to keep their operations running at optimal performance,” comments Trevor Angell, Chairman of the Board of Directors of Wenger. "During our interaction, it was apparent that there is great strategic and cultural alignment between Wenger and Marel. Our shared values and vision, our care for customers and employees, and the combined technical strengths of the two companies will create tremendous value in global food production. We are pleased to be joining forces with Marel, and we are excited for the opportunities our friends and teammates will experience.” The deal means that the two technical leaders will join forces to transform the way food is processed. Some financial arrangements have still to be finalised, however the closing of the acquisition is expected to be completed before the end of June 2022.

Equine nutrition A brief guide to the multi-faceted dietary needs of the horse


by Caitlin Gittins, International Petfood magazine

s reported by the British Equestrian Trade Association in 2019, horse owning households may be in a decline in the UK, but the number of regular riders also rose from 1.3 million in 2015 to 1.8 million in the same year. Horses are widely recognised as belonging to two groups: professional horses which encompasses breeding, Olympic disciplines and racing, and leisure horses which include riding schools, trail riding and tourist attractions. These are but a few examples of the wide-ranging parts horses play within our society and stress the importance of looking after the estimated 847,000 horses (as of 2019) that reside in Britain. Maintaining good health in horses starts with nutrition: what we feed our horses will directly impact on their health. The modern day horse, Equus caballus, is the result of some 55 million years of evolution. Most noticeably, modern horses have evolved high-crowned molars, in order to better deal with the consequent dental wear from foraging grasses. Its ancestors would have likely possessed short-crowned molars suggesting they subsisted on a diet of fruit. Other key details of a horse’s anatomy reveal how the modern horse eats and digests food.

How to feed horses

Horses are non-ruminant herbivores, much like camels or rabbits, which refers to their lack of a ruminant digestive system and single stomach, which is comparatively small for an animal of its size. Its digestive system can be broken up into the foregut, which makes up the stomach and small intestine, and the hindgut, which is made up of the cecum and colon. Horses are also known as hindgut fermenters, which refers to the process of carbohydrates such as fibre being fermented in the large intestine or cecum. Gaining a better grasp of its anatomy reveals important details about how to feed horses. For example, because of its small stomach, horses can either eat continuously or eat small meals frequently. They are also not in possession of a gallbladder, so high fat diets are hard to digest – they can be fed a diet with a

maximum of 20 percent fat, but this is only when introduced slowly and gradually. Nutritional advice for horses today is frequently taken from the National Research Council’s ‘Nutrient Requirements of Horses,’ with the revised sixth edition published in 2007 which is an in-depth resource on equine nutrient requirements and the best feeding practices. Written chapters correspond with the six classes of nutrients horses need in order to survive: water, fats, carbohydrates, protein, vitamins and minerals. According to the National Research Council (NRC), water is incredibly important as a means of maintaining fluid balance. The total body water in horses has been estimated at around 62 to 68 percent. Carbohydrates provide the principal source of energy in horse diets and mainly come from forages, grain and grain by-products. Forages include legumes or grasses, with commonly used legumes being clover and alfalfa, while hay is forage that has been harvested, dried and baled. Horses are naturally grazing animals so providing them with the opportunity to graze in a pasture will allow them to freely pick from the grasses available. The nutrients provided by forages depend on their maturity, fertilisation, management and environmental conditions.

Considerably increasing palatability

Fats have proven most beneficial where derived from vegetable sources in comparison with animal sources due to its palatability. Adding fats to forages or grain considerably increases its palatability. Protein in equine diets take into account 10 essential amino acids that are required: arginine, histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan and valine. The ideal protein diet will formulate a diet with the right amount of these amino acids. Minerals are mostly obtained from forages, and include calcium, phosphorus, magnesium,

potassium, sodium, and chlorine, each of which has uses related to muscle contraction, transporting substances and acidbase balance, for example. Vitamins are essential to normal metabolism and can be divided into two kinds: the fat soluble vitamin A, D, E and K, and water soluble vitamin B and C. Although general advice on equine nutrition exists, it’s important to note that nutritional advice on each nutrient class varies depending on a number of factors related to the horse. Six classes of horses are recognised by the NRC which directly affects their nutritional requirements: growing animals, lactating mares, pregnant mares, stallions, working horses and adult horses not working. There are subclasses within each class, for example, the activity levels of working horses are divided into: light, moderate, heavy, and heavy exercise. Other factors that will impact on nutrition include stress, injury, management and housing. Nursing foals, for example, need large quantities of milk that won’t be present in an adult horse’s diet. In the early stage of its life, it consumes large quantities of milk: in the first day of its life, it consumes 15 percent of its body weight in milk, a figure which increases to about 25 percent of its body weight seven days postnatal. It is recommended that young foals still be fed a diet partially made up of milk. Whereas on the other spectrum, for senior horses, an important consideration for feed formulation is their ability to digest, as studies suggest that the digestibility of crude fibre is lower in a group of old horses compared with a group of young horses.

Age appropriate diets

If a horse is not fed the appropriate diet according to its age, activity level and health condition, there are tell-tale signs to look for. Adult horses, for example, require eight to 10 percent of protein whereas lactating mares or foals need more: a nutritional requirement that may be overlooked and lead to a protein deficiency or excess. Signs that a horse is lacking protein include a coarse coat, weight loss, reduced growth and milk production. If a horse is being fed an excess of protein, however, they may increase their water intake, urination and sweat losses. If a horse is dehydrated, as another example, signs of this include a decreased feed intake, reduced physical activity and dry faeces. One anticipated outcome of a diet with a high-fat content, is that an adult horse with a low activity level fed it will become overweight. An overweight horse poses a number of health-

related problems, including increased stress of the heart and lungs, strain on joints and limbs and the ability to become more easily fatigued. As the ideal body weight can vary depending on the horse’s age and activity level, the Henneke Body Condition scoring system assesses amounts of fat in six areas: covering the neck, the withers, the crease of the back, the tailhead, ribs, and behind the shoulder at the girth. The scoring system ranges from one to nine, with a score of one suggesting that the horse is emaciated, whilst a score of nine indicates the house is overweight. A score of five is generally accepted as an ideal condition. Feeding a horse the proper diet is not just key for keeping it in good health, but to ensure a high food conversion rate, and reduce the amount of waste produced by the horse. Current advice suggests feeding a horse around 1.5 to 2kg of feed per 100kg of its body weight. Nutrients that horses do not utilise properly are expelled in urine and faeces, the amount and composition of which depends on the composition of their diets. There are a couple of options for the disposal of horse manure. One age-old practice of utilising horse manure is to recycle it by using it for agricultural purposes as fertiliser. Horse manure contains high levels of nitrogen that prove beneficial to plants such as garlic. This method, however, is flagged by the NRC as one reliant on land availability, as modern animal production continues to upscale. A second, less environmentally-friendly option is to send waste to landfill, at which point proper laws and regulations need to be adhered to.

Equine nutrition is multi-faceted

Maintaining good equine nutrition might appear daunting at first, but there are online tools out there to make it just that bit easier to formulate the right diet. The National Academies website (, provides a free online calculator for those who want to calculate the nutrient requirements of their own horse. The website is based on the sixth edition of the NRC’s Nutrient Requirements for Horses which, as mentioned, is a commonly cited resource for those involved in equine nutrition including veterinarians, nutritionists, and horse owners. As demonstrated, equine nutrition is multi-faceted, needs to consider different aspects related to the horse, and is overall instrumental in keeping horses in their best health.

Safe horse feed storage How to prevent loss through staleness, mould, vermin & accidents


by Andrew Wilkinson, International Petfood magazine ourishing a horse with good quality feed plays a large part in maintaining it in good health - so it is important that it is kept in a way that will maintain its nutritional value. This is because unless horse feed is stored correctly, even good quality ingredients will

deteriorate. Most feedstuffs that are fed to horses, such as oats, barley, alfalfa, chaff and equine mixes, will go mouldy or stale after just one week if the sack that it is stored in is left open to air and dampness - which is why horse feed manufacturers generally recommend that their products are stored in airtight containers. Another very important reason to store feed well is to prevent a horse or pony gaining access to it and gorging themselves. The consequences of this can cause equine colic, laminitis or even death if a pony should get in and eat a large amount of dried sugar beet. Feed should also be stored in a way that prevents vermin such as rats and mice getting into it. Rats and mice do not just eat up the feed causing a financial impact, they can also spread disease and infections to a horse or pony too.

Dry, well ventilated, clean & tidy storage

Storage areas for equine feed should be kept dry, well ventilated, clean and tidy. This is because keeping the feed storage area swept clean will make it less attractive to mice and rats. Placing mice and rat traps in your feed room or keeping a stable cat are other ways of keeping the rodent population down

– although many more humane options are also available. Oxidation (a result of exposure to air and light) leads to a breakdown of nutrients in grain rations. So, while you have to watch that sacked grain doesn't become moist and mouldy, you also have to keep moisture out of the feed bins by using tight-fitting lids. Trash cans are a popular storage option, with the possible problem of condensation on the lids of metal cans, so for this reason plastic is the better choice. Plastic cans are inexpensive, can be washed easily, and hold between 50 and 100 pounds of grain. Sacks of equine feed should also be stored out of direct sunlight to prevent moisture loss through condensation and caking of ingredients. They should also be stacked on pallets to help keep damp and moisture out. Placing them on pallets will also keep them off damp ground and allow some air to circulate underneath. Keeping feed sacks away from damp external walls is a very good idea too. This arrangement will also increase the chances of spotting any tell-tale little signs of mouse or rat activity, such as if any small piles of grain start to appear under and around the pallets. If you buy many sacks of horse feed at one time in bulk, stack these so that you can see when the expiry, sell by, or best before date is, as this will ensure that the oldest feed is used first, avoiding wastage.

Storing opened sacks of horse feed

Once sacks of feed have been opened, we should always keep them in a rat and mouse proof container, with galvanised feed bins or dustbins an ideal solution for this. Take care to tightly reseal any tubs of equine feed

supplements to retain their freshness. It may be a good idea to store plastic tubs of supplements inside a metal container because as previously stated, mice and rats will often make very easy work of chewing through plastic containers. Some horse owners choose to store their feed in plastic dustbins or trash cans - but rats and mice will eventually chew their way into these, so regular inspections should always form part of your weekly if not daily routine. If you do use one of these vessels to store your feed, always use up the old feed and clean the bin before adding any fresh new stock – first in first out (FIFO) is a good policy to adopt here and will help you to minimise the risk of mould developing. One ‘make do and mend’ solution that will also help to keep things fresh is to use an old broken down open top chest freezer. That said, as these large lidded troughs are usually airtight, do make sure that there is no chance of a child falling in – or even the stable cat getting locked inside! A full risk assessment may seem a little overkill, but they have been known to save lives and is much easier than dealing with serious injury or death as a result of an easily preventable accident. As well as the prevention of invasion by unwelcome pests, curious children and greedy cats - the feed storage area should be secure so that there is less chance of a horse or pony getting into it and clearing out your feed stocks.

Safe horse feed storage in five easy steps: 1. Keep it dry – Store feed in airtight containers, be wary of condensation on warmer days – avoid damp ground and direct sunlight. 2. Keep it fresh – Remember the ‘First in, first out’ rule, clean your storage area before adding new stock. 3. Keep it high - Having feed raised off the ground to make spotting signs of mouse or rat activity easier. 4. Keep it safe – Make sure your feed bin is properly secured. Consider conducting a risk assessment. 5. Keep it secure – a locked storage bin means there is less chance of a horse or pony getting into it and clearing out your feed stocks.

Hydrolysed new alternative for yeast The petfood formulation


by Francesca Susca, DVM, PhD, Pet Development Manager Lallemand Animal Nutrition, Canada

east and yeast derivative products are versatile and natural ingredients to keep in mind when formulating food for pets. They can be used for everything from a palatability enhancer to a source of nutrients and functional ingredients. This article focuses on the characteristics and benefits of a new ingredient for petfood: a specifically designed functional hydrolysed yeast. Yeasts have been part of the human diet since at least ancient Egypt when they were already used to leaven bread and ferment wine. Their exceptional fermentative and nutritional properties also make yeasts valuable nutrients for animals. Not all yeasts are equal. There are about 60 genera and about 1500 species of yeasts. Only a few are used commercially. Saccharomyces cerevisiae is the main yeast used in food, beverage and baking as well as in animal nutrition. Yeast in animal feed is either used live (probiotics) or inactivated. There are different types of yeast products: wholecell inactivated yeasts, autolysed yeasts, hydrolysed yeasts and yeast extracts, each with its own production process and nutritional properties (figure 1). In the case of whole-cell inactivated yeasts, yeast are heat inactivated, but there is no lysing step. The final product will have a low nutrients digestibility and functionality. For autolysed yeast, the yeast cells are partially lysed by endogenous enzymes, which enhances the digestibility compared to a basic inactivated dried yeast. However, this autolysis process is less controlled than a hydrolysis. The production of hydrolysed yeast involves the addition of specifically selected enzymes. These are chosen to orient and control the lysis, ensuring a specific level of functional ingredients and a consistent batch to batch product composition. This is why yeast company Lallemand has focused on the

screening of different feed-grade yeast biomasses and on the optimisation of their production processes in order to introduce to the market a specifically designed functional hydrolysed yeast for animal feed: ‘Yela Prosecure’. To create this product, a controlled hydrolysis process is applied with the addition of specifically selected exogenous enzymes to the selected biomass, ensuring high nutrient digestibility and functionality while providing reliability in terms quality and availability of appropriate volumes. The hydrolysed yeast Yela Prosecure is a feed material (Regulation (EU) No 68/2013) allows nutritionists 1) to diversify the protein sources in the diet while 2) bringing functional properties and enhancing palatability.

Mode of action

The product provides functional nutrients with dual action: in the upper gut and in the hindgut. In the upper gut, the hydrolysed yeast provides highly digestible proteins which offer a high level of free digestible amino acids with an early and fast absorption kinetic. This was demonstrated through in vitro kinetic studies

comparing the digestibility of Yela Prosecure to different feed protein raw materials (such as soybean meal, fishmeal, potato protein) as well as other types of yeast-based products (inactive dry yeast and autolyzed yeast) (fig. 2). This advantage is related to the specificity of the production process, showing the importance of a controlled hydrolysis which makes proteins more accessible, having been lysed into free functional amino acids and small peptides that are readily and directly absorbed. Once it reaches the hindgut, the remaining part of the hydrolysed yeast consists mostly of fermentable insoluble carbohydrates inducing a late energy release supporting fibrolytic microbial populations leading to an improvement of microbial diversity and activity, with a release of valuable short chain fatty acids (SCFAs), such as butyrate, and a decrease in proteolytic microbial compounds production, like ammonia.

Figure 2: Kinetic protein digestibility of different feed raw materials in vitro (Lallemand Animal Nutrition internal results).

Palatability enhancement

Palatability trials in dogs have shown the potential of Yela Prosecure to enhance petfood palatability (figure 3), likely related to the high natural content in glutamic acid.

High quality & highly absorbable nutrients

Yeast is a formidable bioengineering factory and a source of valuable nutrients and functional molecules. Hydrolysed yeast produced with an optimal lysis process enables formulators to take maximum advantage of these nutritional and functional properties. They can support digestive care and enhance petfood palatability while contributing to the protein balance in a context of partial substitution of conventional protein sources.

The ‘humanisation’ of petfood


Is driving new capacity among petfood manufacturers

new US Horizons report from CRB, a major international food and beverage production facilitator, finds that petfood manufacturers are actively responding to add capacity that meets consumer demand for highquality products, driven by the desire to facilitate the ‘humanisation of petfood.’ Even as supply chain risks, labour shortages and rising costs present stout challenges, CRB’s newest Horizons report finds established companies and start-ups alike are chasing consumers who increasingly demand the food they feed their pets matches the quality and manufacturing standards of food they’d feed themselves. The report, released in May of 2022 by CRB – a leading provider of sustainable engineering, architecture, construction and consulting solutions to the food and beverage and life sciences industries – is built on the survey responses of 300 petfood manufacturing leaders. Horizons features analysis by CRB’s authoritative corps of subject matter experts who share insights on issues ranging from the sourcing of alternative proteins and adapting processes for sustainability, efficiency and quality, to embracing integrated project delivery solutions that raise capacity without sacrificing quality or schedule. “At stake is nothing less than a projected US$275 18 | May 2022 - International Petfood


billion, the expected annual value placed on the pet care industry by 2030,” Tim Barba, CRB’s Chief Operating Officer, Global Technical Operations, writes in the opening passages of the report. “To get their share, manufacturers are feverishly expanding and modernising their production capacity, exploring new segments and aligning their products with the qualities prized by ingredient-conscious consumers.” Among the essential insights contained in the Horizons report:

Product innovation:

Petfood manufacturers face the difficult task of balancing premium formulations with acceptable selling prices, expanding beyond bulk kibble and experimenting with alternative ingredients. CRB experts examine these shifts and offer solutions for manufacturers unsure of their next steps.


Process teams are embracing innovation to find new ways to optimise existing methods. The report examines this quest for getting more from every piece of equipment.

Project execution:

More than half of Horizons survey respondents plan to embrace integrated project delivery to address automation and sustainability in petfood plant design.


While respondents have prioritised packaging as their top capital expense objective for the next five years, how can they ensure the investments will address rapidly changing market conditions?

Operational improvements and efficiencies:

The report provides practical insights for petfood manufacturers as they seek to align capital spending strategies with operational goals while future-proofing operations.

Quality and safety:

Petfood manufacturing is setting new standards for all food manufacturing regarding quality and safety. The report looks at this trend and how it will impact the future of a maturing petfood industry.


While companies strive to hit net-zero goals quickly, how they achieve them is unclear. Whether driven by retail requirements or consumer demands, the report investigates why barriers and myths must be eliminated to achieve progress. “It’s fascinating to see how the massive adoption of pets in the United States during the pandemic transformed the petfood industry. “Despite inflation and other challenges, consumers are seeking high-quality foods for their pets who are treated like family members,” says Jason Robertson, Vice President of Food and Beverage at CRB. CRB is a leading provider of sustainable engineering, architecture, construction and consulting solutions to the food and beverage and life sciences industries. The company's more than 1600 employees provide world-class solutions that drive success and positive change for their clients, people and communities.

The benefits of using insects in petfood Sustainability, nutritional advantages and what’s coming next


ith the world population expected to exceed 9.7 billion by 2050, food production needs to increase by 70 percent to meet the demand, according to the Food and Agriculture Organisation of the United Nations (FAO). In Europe, the protein deficit issue is strongly related to the lack of self-sufficiency in the supply of animal feed ingredients (i.e. high protein materials) in order to respond to current meat protein demands. As a result, many countries are looking for locally produced food and feed that won’t further pressure our planet and its natural resources. Within this space, new sources of high-protein feed materials such as insects offer great promise. Being mainly produced in the EU, insect proteins can help reducing the dependency on imported sources of proteins for use by European livestock producers as well as improving the resilience and self-sufficiency of our food supply chains. This became even more relevant in the context of the war in Ukraine which is expected to have serious repercussions on the European agri-food sector with long-lasting impacts on food security. So, how is the sector going to meet the growing demand? What can we find already in the market and what to expect in the near future? Throughout this article, we will provide a concise overview of the latest developments regarding the insect-derived feed ingredients and upcoming trends.

by Alice Grassi, Communication Manager and Christophe Derrien, Secretary-General, International Platform of Insects for Food and Feed (IPIFF), Bruxelles, Belgium

The benefits of insects as feed Sustainability

Its reduced environmental footprint and high efficiency in terms of water and land footprint, all contribute to the sustainability of insect farming. Thanks to the vertical farming techniques implemented, insect farming requires less arable land as insect farmers use ‘crates’ aligned vertically to rear their insects. Most commonly farmed species are able to absorb the water they need from their substrates. Moreover, insects can also contribute to reducing the burden of food waste, being fed with underused agri-food by-/co-products (e.g. vegetable/fruits/starch origin) or food no longer destined for human consumption (e.g. unsold products from supermarkets, food products arising from the food manufacturing and being discarded for technical reasons). Thus, the local production of such feed ingredients not only strengthens agrifood circularity - but it also improves regional self-sufficiency.

Nutritional advantages.

Biologically speaking, insects are not at all new to fish, poultry or swine species: in their natural environment, such animals eat larvae, flies or other insects. In nature, these animals would forage for roots, seeds or insect larvae characteristics that are also visible in the behaviour of farmed pigs. These ‘ingredients’ now reappear ‘on their plate’, contributing directly to animal growth, health and welfare (e.g. stimulating their natural behaviour). Scientific evidence confirms that the incorporation of insects in poultry’s diet would reduce aggressive reactions, such as feather pecking (Star et al., 2020). The omnivorous diet of swine species makes them extremely versatile and adaptable. Insect proteins contain all relevant amino acids for animal nutrition - with adequate levels of lysine, threonine, methionine, and tryptophan. In terms of

20 | May 2022 - International Petfood


vitamins, the inclusion of insect-derived ingredients may complement the lack of vitamin B12 in ingredients of vegetal origin or in organic farming. Ensuring a balanced diet for such animals – that includes ingredients of both vegetal and non-vegetal origin (insects) is key to ensuring better animal performance and higher productivity.

Consumer acceptance

European consumers’ attitude around food is gradually changing - while the demand for a high protein targeted nutrition food is growing. As the need for sustainable complementary sources of proteins is increasing, consumers start to show interest in food that has a lower environmental footprint or health benefits, such as insects. Consumer perception may also change depending on the regional/national availability and accessibility to insectbased products and the different dietary habits across Europe (Such as: flexitarians, organic food consumers or those following a paleo diet are generally paying more attention to sustainable food sourcing and/or to the health effects of what they eat). In terms of animal nutrition, we see higher consumer awareness with respect to the benefits of insects as feed. Such consumers also value that insects are part of the natural diet of farmed animals such as poultry, pigs or carnivorous fish.

IPIFF believes that targeted communication towards the consumer- especially on the many advantages (taste, environmental and nutritional) of insects and derived products such as powder and oil is key.

EU legislation and recent developments

The market of insects as feed is dynamic and depends on a series of factors. Among these, the regulatory context played an important role in the European Union. Notably, following the authorisation of insect PAPs in aquaculture (i.e. July 2017), the aquafeed market became the main target for feed business operators (FBOs) - i.e. Until then, PAPs could have only been used in petfood or technical (non-food/feed) applications (e.g. production of biobased fuels, or other bio-based materials such as bioplastics).

2021 was a year of major developments for the European insect sector. Following the positive vote from the EU Member States in April 2021, the Commission Regulation (EU) 2021/1372, formally authorising the use of insect PAPs in pig and poultry feed, entered into force on September 7, 2021. This authorisation opened two of the most relevant EU animal feed markets, which represent circa 65 percent of the EU compound feed production. Following the entry into force of this implementing regulation, the demand for insects as feed is expected to grow, leading to an increase in the production capacity of the sector. The authorisation of insect PAPs in poultry and pig feed will offer new opportunities - starting with the incorporation of such ingredients into the diet of such animals, the subsequent use of insects in organically farmed chicken and pigs, implicitly strengthening partnerships between insect and animal farms. IPIFF estimates that, by the middle of the decade, most of the demand for insect meal will lie in the petfood sector (circa 40-50% of the insect meal produced). Subsequently, the trend noticed after the authorisation of insect PAPs in aquaculture feed should continue - leading to a steady increase (reaching 25-35% in terms of share), stimulated by a growing demand for aquaculture products, such as carnivorous fish (e.g. trout, salmon). According to our forecasts, the next relevant market for insects as feed operators in terms of quantities of insect meal sold will be the poultry (20-30%) and pig markets (5-15%) - that will see a rapid increase following the entry into force of the approval of insect PAPs in 2021. By the end of the decade (light green in the visual above), the market share of insects as feed produced for the aqua feed market may surpass the petfood market. The other animal feed sectors will represent a similar share to the one from 2025 – however, factors such as consumption patterns (e.g. increasing demand for lower footprint meat – such as chicken) and regulatory developments (e.g. how quickly the insect sector will upscale) may influence this distribution.

Upscaling - what’s coming next?

Following the recent milestones achieved last year from the insect PAPs authorisation in poultry and pig feed, the Novel Food authorisations for edible insects (visit the dedicated webpage at: and the developments of standards for insect frass, IPIFF is committed in unlocking new opportunities for the European insect farmers. Future possibilities such as the diversification of the inputs authorised as insect substrates (what insects eat) could upscale the insect farming sector. Indeed, up to a third of the food waste generated presently in the EU may be used as insect substrate before it is classified as ‘waste’. Currently, by-/co-products from grains, starch, fruit and vegetable supply chains products are authorised as substrates for insects. In the future, the possible authorisation of former foodstuffs containing meat and fish and catering waste would play a key role in upcycling the production capacity of the sector. IPIFF is discussing with the European Commission services on building/collecting scientific evidence which would allow the European Food Safety Authority (EFSA) to confirm that the use of these materials as feed for insects to entail safety risks. In parallel, the organisation supports the objectives of the EU Organic Action Plan in achieving at least 25 percent of the EU’s agricultural land under organic farming by 2030 and a significant increase in organic aquaculture, in line with the ‘Farm to Fork’ strategy. Locally produced feed and food ingredients, such as insects and fertilising products compatible with the concept of organic farming, such as insect frass, could provide farmers with all the necessary tools and instruments that would allow them to convert to organic systems. Moreover, the recent regulatory developments, mentioned above, would contribute to develop EU organic standards for insect farming unlocking its full potential towards a more sustainable food system. Indeed, thanks to the recent PAPs authorisation, insect PAPs may be used up to five percent in the feed ratio of organically produced chicks and piglets.

WE NEED TO CHANGE THE WAY WE FEED OUR PETS How small & mid-size organic insect producers are making petfood more sustainable pets


by Martin Sieland, Managing Director, Terra Pura Tiernahrung / purento GmbH, Speyer, Germany

oaring prices, inflation, gas and energy deliveries at risk due to a war at the eastern border of Europe, together with the slow end of a three year long pandemic situation worldwide – are all continuing to have an adverse effect on our lives. In Germany, 60 percent of all crops produced are used to feed livestock and the evident risk that supply from Eastern Europe is at risk, for the immediate future at least, is making us realise that we have to change the way we consume, what we buy and how we conduct our everyday lives. This is especially apparent when looking at two facts. Firstly, the unworthy industrialisation of our livestock which is not in accordance with the UN sustainability goals, and secondly, the feed structure for livestock and domestic animals, where we are feeding parts of our own food chain. We are faced with an urgent need of change to implement new feed sources which do not include parts of our own human diet. With a constantly rising world’s population and food resources at risk we have never been faced with such a dramatic impact and possible shift on our consumer behaviour. The world in which we live in needs to be taken care of in order to make sure that our grandchildren and great-grandchildren will still find a liveable environment. It’s now the time to reflect and think about how we are living and how we can live in the future.

We have to change

Now let’s take a look at petfood. Our good and trustful

companions on four paws have become family members in the past years. We socialise with them in a different way, they are among our families every day, we identify them with the same socialisation as we do with our kids and we feed them in the same way as we nourish ourselves. Still, if our initial observations are true, we have to change the way we feed them. This change can happen in two dimensions on one side we can improve the quality of petfood by preventing the conventional, industrial petfood producers using pet by-products such as feather, claw and bone flour or artificially modified and produced animal proteins. These products are not meant to create a circular economy, their only intent is to increase the profitability by offering cheap ‘alternative’ protein sources. From an economic standpoint, this is acceptable but the reelaboration of different animal protein sources in these processed flours has led, as scientifical researches have shown, to an increase of allergies, food intolerance and intestine diseases for dogs and cats in the past 30 years. The second dimension is that we have to reduce using traditional animal meat sources in petfood, we have to identify new single protein sources, which have a lower environmental impact in order to become more sustainable and still offer rich and nutritious petfood on a single protein source and with high nutritious quality. Researches have sufficiently shown that rearing insects has a lower impact on greenhouse gases released, lower quantity of feed is needed, and the amount of water and land required is just a fraction compared to traditional meat sources. Yet the selection of insects we can decide for insect species which can meet the

24 | May 2022 - International Petfood


aspect of circular economy: silkworms. Silkworms are just a by-product of the silk industry in India, South East Asia or China. If they are used, they are used as fertiliser or in most cases simply discarded. Each year 250,000 tons of silkworm pupa are produced, containing 40,000 tons of protein, protein which simply doesn’t cost anything, and we cannot allow not using this nutritional source. Especially when we know that silkworms are hypoallergenic and as recent researches in Netherlands have shown they can have a positive impact on inflammatory joints and even improve the brain capacity for older dogs.

For where ever you are!

Replacing expensive animal proteins

When a cheap and available insect protein alternative is available so why we are simply not replacing expensive animal proteins in our petfood? When selling petfood we are always selling to two individuals: the owner of the pet and the pet itself. Many owners, especially in Europe, react with the ‘yak factor’ when it comes to insects as part of their beloved pet nutrition. Insects are still perceived as small, crawling, dirty and disease carriers, nothing which even a halfway educated European pet owner would like to see in their pet’s diet. This cultural influenced European point of view is justifiable since insects have never been part of our human diet and have never been reflected in our cultural heritage as healthy, positive, nutritious and sustainable source of human diet. However, the increasing world population, avoiding the need to use part of human diet for feeding livestock and home pets, the misuse of unhealthy multi protein flours in conventional pet nutrition and the mandate to preserve our planet expressed in the

UN sustainability goals are simply sufficient facts to change our behaviour and how we feed our pets and overcome long established cultural views. Similar changes have happened already when we look at human diets and food behaviours. Eating raw fish for example has never been common in Europe and only used in regional cuisines for example in Spanish/Catalan recipes called Cheviche or in Italian and French cuisine when looking at raw tuna salads. The introduction of Sushi, Maki and Negiri in the 60s and 70s by Japanese guest workers in Europe has led to the beginning of a triumphal march which ended in knowing Sushi nowadays as a Europe widely accepted take away and daily convenience food – no longer seen as a foreign specialty. When looking at the changes we are currently facing and when understanding the sustainable mandate, we are having towards our planet and the future generations living on it we recall that not the strongest individuum is set to survive but the individuum which can best adopt to change – and this change is happening right now.

Giving back value

Organic insect petfood is one solution and response to these changes we face. Rearing livestock under organic conditions and licensed with organic labels is giving back value to our livestock which it lost during the past decades when it became an industrialised commodity. Meat is not a commodity we can have three times every day in every meal. Not with a fast growing world population, not with the need to preserve our planet as expressed in the UN SDG’s and logistic supply at risk as soon as a pandemic is interrupting our supply chains and having ballistic conflicts back in Europe. Organic petfood is creating a circular economy in organic livestock production where it implies reducing waste to a minimum and creating further value to this economy. Especially when we know that silkworms can be used as a single protein alternative and add value to the satin production. Many animal parts are not finding its way in human diet anymore, organic petfood is creating further value by offering pets a healthy single protein and avoiding cheap, processed multiple protein flours which simply led to a deterioration of a domesticated pet’s overall health and constitution. We know that the European Union has revised and developed legal guidelines for import of insects as food and feed beyond the Regulation (EC) No 258/97 on novel foods and novel food ingredients, thanks to the support of AFFIA (Asian Food and Feed Insect Association) and IPIFF (International Platform of Insects for Food and Feed). This not only allows and rules the import of whole insects such as crickets, mealworm and black soldier fly larvae into Europe, but it also supports the inner European development of rearing insects as a sustainable and alternative single protein source.

Rearing insects in an organic way

Organic certifiers reacted to this development and there are two guidelines on how to rear insects in an organic way, which is Bio Suisse and Naturland guidelines. There is still a long way to go when we can offer organic insects in organic petfood reared in Europe. However, knowing that the import of insects from Asian countries is set into legal guidelines creates assurances that insect raw materials are finding their way to Europe from countries where insects are reared in a natural and fully sustainable way. Naturland organic insect framework is based on the association’s core fundamental principles of certified organic agriculture:

the obligation to treat the elementary basics of our lives with prudence and responsibility, sustainable management, protection of climate and preservation of soil, air and water and the protection of the consumers.

The circle economy

When looking at the feed, attention is paid to the circle economy when feed and substrate originates from organic agriculture (preferably from the farm itself or from growers and/ or processors in the same region). Animal products as well as their residual materials and by-products are not permissible as feed. We interpret it as a strong sign of transition between organic and conventional agricultural production that Naturland allows, where organic by-products and residual materials are not available, then by-products and residual materials from the processing of conventional foodstuffs and conventional fodder may be used but only upon submitting application to Naturland for permission. Analysis submitted before must show that feed is harmless and does not content pesticides, mycotoxins, heavy metals, GMOs etc. Terra Pura Tiernahrung ( just finalised the recipe development of an organic wet food for dogs based on silkworms, is currently finalising the test feeding and is presenting the product to the German market in Q3 2022 with silkworms sourced in India and Thailand. Customers reacted very positively to the initial market research of the company and a common response was that customers see this as a feed solution not only for allergic and hyper-sensitive dogs and welcome the regional production without additives, colouring and conservatives. The development of an insect snack based on black soldier fly is set to be presented in Q3 2022 as well.

Overcoming development & production difficulties

The company is facing difficulties with the development and production of an insect dry food based on organic raw materials. A few insect dry food producers are existing in the market. However, they do not service the needs of an organic SME petfood company. None of the recipes offered is based on organic raw materials and the exclusion of additives, colouring and conservatives is not available at present. Compromises are accepted since there is no offer of organically produced and reared insects available in the market and dry food would therefore be similar to a dry food based on horse or boar meat where both are also not available in organic quality. Furthermore, having an influence on the kind of insects used in dry food would also be appreciated. Most of the current offers specialise in black soldier fly and it has been proven that customers have a negative culturally influenced European view on these insect species. Last but not least the minimum order quantity for dry foods is often a stretch for Small and mid-size enterprise (SME) companies and minimum order quantities of 10 tons is simply too high. To support the implementation and development of insect dry food with organic raw materials, it would be beneficial to have lower minimum order quantities and influence on the recipe and insect selection. A development of new kind of food and feed is always driven by SME companies and processing industries should find a way to meet the pioneering spirit and find solutions which help both sides.

Sustaining life’s simple pleasures on an industrial scale

by Ada Wei, Famsun MY View Magazine Editor, Japan

hen adapting to living in a world that becomes ever more complicated, whilst also accepting that the pandemic will be part of today’s life for many more years, a large number of people have decided to help themselves to become happy again by reconnecting with simple things, like cats and dogs. Life with their beloved pets brings many benefits to pet owners: from physical health to mental wellbeing, which is why the population of pet owners rises continuously amidst the Covid-19 pandemic. This is also the reason why Famsun and other global petfood producers continue to work hard to bring modern industrial pet food production systems to locations all around the world. In doing so, these companies serve the needs of millions of pets and their owners and protecting what’s good in life through health, nutritious and tasty petfood.

Innovation: Driving change for better

Pet parents today care more about the nutrition, health, and well-being available for their pets, than they have done so previously. For example, nutritious and fresh-ingredient food such as high fresh meat products have become a popular splurge item. Many owners are also willing to pay extra for innovative choices that can solve allergies, picky eating habits and immunity issues. Some are also willing to pay extra for ‘green’ products that are sourced and produced responsibly and are aligned with their family sustainable actions. At Famsun, its experts move fast to innovate and

provide competitive, sustainable, and tailored petfood processing solutions that help producers and investors to seize new market chances and become differentiated in the marketplaces. The company’s R&D institutes in the USA, Denmark, and China, have dedicated their activities to the petfood industry for decades, and are constantly working on innovations to increase the capability of petfood plants to make them process smarter, more efficiently and more sustainably. Famsun has been researching high and ultra-high fresh-meat petfood production technology for years. In 2019, the company successfully launched a dry petfood line with up to 70 percent fresh meat. Since then, its experts have worked on improvement to meet this higher addition demand – and 2021 saw a breakthrough with several 90 percent meat petfood processing lines starting operations in China, Southeast Asia, the Middle East, and South America. In addition to the previously listed innovations, Famsun also develops more specialised equipment such as the FE series single-screw extruder, R series twin-screw extruder and the CYPZ vacuum coater for petfood production. These machines are flexible enough to meet different customised petfood formulas, and the base materials of all product-contact surfaces or parts are food level. The Famsun CYPZ vacuum coater, especially, allows producers to differentiate their products at the line end through applying different functional liquids onto the food pellets, be it oil/fat to

Industry Training

Live, online & globally recognised


How to gain a feed production qualification without leaving the comfort of your own home ith soaring prices, the war at the eastern border of Europe, together with the slow end of a three year long worldwide pandemic situation – we are all faced with a great degree of uncertainty in all of our lives. As world markets continue to tighten, so too does the competition for jobs in the animal feed production industry, making this the best time to sure up your CV by adding a globally recognised industry specific qualification. April 2022 sees the long-awaited return of both the Online Aquafeed Production School course for its Spring 2022 edition, which sees a new, improved and updated online bunch of broadcasts. Developed by Progressus Agrischools and presented in partnership with Perendale Publishers Limited, this course is tailored to help attendees to build an understanding of the design, development, and operation of an aquafeed and livestock feed production plant, covering the entire range of products used in this industry. This goal is achieved through twelve two hour long weekly sessions featuring industry experts who share their extensive knowledge relating to feed ingredients, the equipment used, as well as providing a general nutritional review. This is then followed by a dedicated question and answer session, allowing participants to interact live with the program facilitators. These carefully selected experienced industry operators, who possess centuries of combined front-line service between them, includes Joe Kearns, who alone has spent decades in senior roles at Wenger Manufacturing.

Wisdom & reliability

The Spring 2022 edition of Online Aquafeed Production School sees Mr Kearns take over the role of lead presenter, a role that he will no doubt deliver with the same level of professionalism that has seen him earn a solid reputation throughout his career for wisdom and reliability. Online Aquafeed Production School will enable interested individuals to understand the possibilities and developments over time with regards to what can be produced, as well as examining how all aspects of the process interact in order to achieve and maintain a successful standard of aquafeed production. Basically, there are four areas of importance for aquafeed production; ingredients, equipment used, how it is operated, and the desired final product specifications. All aspects interact as each affects the other as the nutritionist makes the formula, sales or the customers define the desired end product while the production needs to perform efficiently.

Communication between these areas and the interactions between them will vastly increase the chances of producing positive results, including excellent aquafeed produced with acceptable margins.

Sessions 1 & 2 recap

The first edition of this long-awaited new series seeks to provide attendees with an ‘Overview of the Aquafeed Process.’ Introduced by the able presenting duo of Messieurs Christodoulou and Gilbert, this was split into four main parts. The first of these segments sees Mian Ruiz Texas A&M University broach the subject of the ‘Different Types of Aquafeeds. Mr Riaz’s teaching is then followed by the first of Joe Kearns’ contributions titled, ‘Typical Equipment used in Aquafeed Production and Raw material Requirements and Effects’. Mr Kearns then returns to host a new section ‘Useful Troubleshooting Tips’, which this week focuses on raw materials – including aspects such as starch content, changeover time in storage and the ‘after ripening factor’. The fourth and final segment of this sessions sees all but Mr Riaz return to tackle the weekly live Q&A session, with all of the questions asked by the audience answered in full – with Mr Kearns even answering some shortly after they had been answered. Delivered under the title of ‘Starting the Process: Ingredient Receiving, Bulk Storage’ the first address of the second session sees Mr Kearns tackle the subject of ‘Nutrition, Formula, Considerations for Aquafeed Production and Ingredient Receiving’. The lists of related subjects covered includes ingredient sources & specifications, starch in formulation and the differences between coated feeds. The second section of the second session sees Giuseppe R Bigliani, President of Feed Technology Solutions, Engormix provide a ‘Detailed Review of Ingredient Handling – Part 1’. With nearly four decades of experience in the design, installation, operation and administration of projects related with the Agri-business, focusing on feed and food processing plants, Mr Bigliani provides a very comprehensive overview of this subject.

It’s not too late to enrol

Although this season has already started, all sessions are available on demand for two weeks following the final broadcast – with this option included for all attendees at no extra cost. The Aquafeed Production School is running every Tuesday, from April 19 to July 12, 2pm Bangkok time and 9am CET. For those based in the US and Latin America, sessions begin on April 21 and conclude on July 15, 9am Chicago time. The course certification is very beneficial for the workplace, as it both signals an attendee’s interest in the industry and demonstrates an acquisition of the knowledge that they’ve gained whilst attending the program. To enrol on the Aquafeed Production School course, be sure to visit for more information.

Petfood production troubleshooting Part 5: The Extruder



xtruder barrels used in petfood production are either single screw or twin screw in design. Forming extruders are used for some select products – thus our discussion will centre on single and twin designs. Over the length of the barrel three zones define their function, with the first third being what is considered the feeding zone. This is designed to move the preconditioned feed forward so that more feed can enter the barrel. This area is considered to be starve fed, meaning there is always room for more within the volumetric capacity of the screw design. The screws in this area are usually single flight with high volume promoting forward movement of the mash. There are angles to screw flights and typically in single screws the angle on the leading edge of the screw is designed to promote the feed to move forward but also outward, so the mash interacts with the sleeve or casing around the screws. This also allows for the mixing of the mash as it moves forward towards the die, eliminating the stagnate feed movement if the flights were vertical or perpendicular to the shaft.

Previously on Troubleshooting…

The kneading screws

The middle of the barrel usually has the kneading screws, double flight with less volume which can have continuous flighting or possibly what is known as cut flights. The area where the flights are cut promote cook as they increase residence time, mixing and energy input. This is the area where the mash starts to become more of a plastic nature or a melted mass as the pressure also increases. The final third of the barrel is what is referred to as the final cooking zone. The zone where the melted state is complete, and where pressure is at its highest before exiting the die. Usually these screws are double, triple or quadruple flighted. Most single screw extruders have a devise between each screw, a shearlock also called a steam lock. They vary in diameter and usually they get larger in diameter as you get closer to the exit of the extruder. Diameter changes in the later stages of the barrel lock the steam from moving out of this area due to the fact materials is always between them and the sleeve or outer casing.

Twin screw extruders

Twin screws have a smooth outer casing or sleeve while single screws have flighting in the form or either spiral or straight ribs. Spiral promote forward movement of the feed as straight ribs allow backflow this increased resident time and usually elevated cook due to extra friction development. Twin screws do have design differences so the barrel can be configured for the desired cook needed, as both are usually variable speed so screw speed can be altered. Development of flow control valves in the middle of the barrel or at the end of the barrel offer restriction which holds the material in the barrel for additional energy input. When using a mid-barrel valve, the last barrel section can be converted into a forming design if higher density is desired. The end of the barrel design allows for increasing or decreasing the flow creating cook which might yield a system where you don’t have to disassemble the barrel in order to change the cook. There are many combinations and set up designs that allow for a wide variety of formulas to be made with density or expansion control. This review is the basis of future discussion on the extruder barrel components.

The above discussion on screw zones is also seen in twin screw extruders. The major difference between single and twins is the geometry in single screws is basically unlimited as twins require the screws to mesh together, thus variable pitch and variable depth screws are not seen.

1. Density An examination of product density and its relationship with moisture levels, heating, cooling feeder screw rate and automation.

2. Non-uniform and rough appearance

A guide to understanding the science involved in improving the art of making products of all the same size.

3. Extrusion dies

Die designs vary and are usually specific for the equipment manufacturer. This article takes a look at aspects of the process including high, medium and low shear as well the adjustments required when producing feed for small mammals.

4. Dryers

The dryer is without a doubt one of the machines in the system which greatly impacts the bottom line. How? Water is the reason, as products are sold with a max water percentage on the labels, so it is the lowest cost ingredient and one that should be watched closely.

PRODUCTION FOCUS Innovations this month May 2022 This month’s Production Showcase section features equipment and ingredients that will help in the production of petfood, taking you right from the recipe book, right up until until your product is ready to leave your factory door. If you would like your product or service to appear on this page in a future edition of International Petfood magazine, then please contact us at Magnum ST series extruders by Wenger Manufacturing The Magnum ST series has the ability to use higher SME settings with speeds up to 1200 rpm and power levels to 165 kWhr/t. The benefits of having higher SME inputs include the potential for lower bulk density, higher absorbency levels of liquid coating, higher cook levels, smaller cell structure and enhancement of textural properties. The Magnum ST series extruders utilise parallel-shaft twin screws which are ideal for unique processes with extreme operating parameters. The Magnum ST series also have increased process flexibility and rate potential, whilst it is also ideal for applications which require high torque at low extruder shaft speeds. It is also designed for jobs that requires increased rate potential, dependent on SME and shaft speed.

Vacuum Coaters from Feed Tech FeedTech Vacuum Coaters are designed to spray high percentages of fats and other liquids onto pellets and extruded feed. In petfood plants they enable the addition of microingredients, aromas and oils and fats up to 17 percent inclusion. The coaters have a versatile operation and compact design, with low energy consumption. Depending on the model, the volume ranges from 500 to 2800 litres, with the minimum volume being 25 percent of the nominal volume and the maximum being 110 percent of the nominal volume. The maximum percentage of added liquids to the coater is 24 percent, excluding the fats and oils already in the product. Advantages of the Vacuum Coaters include accurate dosing and better distribution throughout the feed, no contamination in the pellet mill or extruder and a simpler and cleaner process, among others.

FA 438 Packaging Machine by Fawema The FA 348 is ideal for the packaging of petfoods, designed for high speed and high accuracy packing of petfoods. This is done using its Carrousel system which allows it to run in a continuous motion while product filling. Packing while in continuous operation means the machine can product outputs of up to 60 bags a minute. It is also built to reduce loads on parts, meaning they are low wearing and down time is reduced. The machine meets strict hygiene requirements in the production of petfood, as hoppers are inserted into the bag reducing the risk of foreign objects contaminating the bag. The use of lubricants can be easily avoided thanks to the accessibility of system parts which also reduces cleaning time. A few further advantages include high performance, friction-free transport and exact bag shaping.

Anticipation grows for the global petfood market event With its organiser, WZF GmbH, expecting to welcome around 1300 exhibitors from more than 60 countries, Interzoo 2022 will be held in Nuremberg from May 24 - 27. With a gross exhibition area of around 105,000 square metres, the self-described “world’s leading fair” for pet supplies will offer trade visitors a unique overview of the global market for the latest products for dogs, cats, fish and other pets. “Despite the challenges created by Covid-19, the global pet industry has developed positively during the past two years,” comments Norbert Holthenrich, President of the German Pet Trade & Industry Association (ZZF), the honorary sponsor of Interzoo. But since the pandemic began, supply chains have been severely disrupted, with production problems and delivery bottlenecks as a consequence. Mr Holthenrich views Interzoo as an opportunity to change focus and pave the way for new business. “Manufacturers and buyers can meet again in person at the world’s leading fair in Nuremberg in order to establish new business contacts and discover products of interest,” he adds.

A guaranteed global market overview

The strong international make-up of the exhibition will guarantee a global market overview, with more than 80 percent of exhibitors coming from outside Germany. The largest international contingents represent Italy, the UK, US, Netherlands and Spain. There will be a total of eleven national pavilions, some of them larger than previously, from Brazil, the UK, India, Italy, Canada, Singapore, Taiwan, the Czech Republic and the US, with France

and South Korea being new additions this year. WZF has recorded growth in registrations for stand space from a number of countries in Europe, such as Turkey (+114%) and Spain (+15%), with about 60 exhibitors each. There is also stronger demand from outside Europe, such as South Korea (+33%) and India (+22%) with well over 20 and 40 exhibitors respectively. As in the past, items for dogs and cats make up the largest share of the products on offer (47%), followed by small animals and rodents (10%), then pet birds and aquariums (8% each). The range of supplementary items for the speciality pet retail sector accounts for six percent, as does petfood technology. Items for garden animals represent five percent, with smaller shares for other segments such as subject-area literature, shop fittings and packaging.

Strong international visitor numbers expected

With the lifting of travel restrictions and the proven hygiene strategy in place, Dr Rowena Arzt, Director Exhibitions for WZF GmbH, also expects strong international visitor numbers. “At previous Interzoo events, more than a quarter of the visitors came from Germany and three-quarters from other countries – about 42 percent from other parts of Europe and a little over 30 percent from outside Europe,” adds Dr Arzt. “We expect the structure will be similar at Interzoo 2022, with fewer visitors from some eastern European and Asian countries in view of the situation there. This does not affect the importance of Interzoo as the world’s leading fair in this sector, and it continues to offer many opportunities for international contacts, interaction and business,” she concludes.

the interview Leah Wilkinson, Vice President of Public Policy and Education, American Feed Industry Association, USA Leah Wilkinson leads the legislative and regulatory team at the American Feed Industry Association, where she has worked for the past 12 years. In this capacity, she interacts with state, federal and international policymakers and regulators on issues of importance to the US feed and petfood industry. She leads several AFIA member committees and has covered the petfood portfolio extensively, whilst she holds a bachelor’s degree in animal and plant systems from the University of Minnesota and resides in Austin, Texas, with her husband and two children.

You have had a rich career in industry, what initially lead you to get into this field of work? Growing up on a swine farm in Minnesota, I knew at a pretty young age that I would do something with agriculture for my career – I just thought it would be becoming a veterinarian or going back home to run the farm with my brothers! I didn’t even know that jobs like mine existed until a college mentor encouraged me to try out an internship in Washington, DC.

That three-month internship turned into a full-time job. I got to experience some very big policy, political and social situations during those first few years and then I was hooked. Having worked for the animal agriculture industry, I brought a unique perspective to my current role, one where I hope our work is making a difference for those who are keeping America’s domestic livestock and pets well fed every day.

Throughout your extensive career what have been the most significant changes that have you observed in the petfood industry? The regulatory changes that have come about from crucial events, mainly food safety, are the ones that have stuck out to me the most. The Food Safety Modernization Act (FSMA), passed into law in 2011, is one of those moments that massively overhauled regulations for the U.S. animal food industry. While I do not believe it drastically changed the way we produce safe feed and petfood in the United States, it did change the language we use and many of our processes. Now, looking back over the past five years of compliance with this rule, I think FSMA has helped our facilities compile all their food safety information into robust food safety plans and boost employees’ awareness of their role in promoting feed and pet food safety. Animal food manufacturers have a good food safety story to tell and FSMA has given them the opportunity to articulate it clearly to regulators, suppliers and our customers.

Going forward, what aspects of nutrition and production would you like to see addressed and why?

As we’ve learned more about animal nutrition, our ingredients and production, the animal food industry has been able to bring forward unique solutions to today’s most pressing challenges, such as climate change. We have seen policymakers on Capitol Hill speaking up for their rural constituents to have access to these technologies so that they are taken more seriously in the global trade environment. The Food and Drug Administration recently received more congressional funding to address this issue, as well as speed up its ingredient review process for ingredients for both domestic livestock and pets, and we will continue to work with them so that they move the ball forward. While I used an example here with ruminant animals, the procedures and regulatory systems are the same for petfood and innovative petfood ingredients impacting animal nutrition and welfare are also slowed by similar hurdles in the regulatory review processes.

What are the most common barriers you feel our industry must continually overcome to ensure we are providing the most efficient and safe products to our customers? What advice would you give to those looking to improve their operations?

Being able to have access to new technology in a highly connected world is one of the biggest barriers our industry must overcome. It is clear that the science of animal nutrition has evolved at a faster pace than our regulatory system and therefore it is more difficult to bring new feed ingredients through our regulatory review systems that were never designed to be used in that manner. Whether it be genetic engineering, direct fed microbials, enzymes or CRISPR technologies, the US regulatory system has not kept pace, which is saying a lot, considering most scientific research and development takes years, if not decades, of dedicated work.

We have a real opportunity now to leverage talks about climate change and food security to spur innovation by urging decisionmakers to embrace more nimble regulatory schemes that prove to industry that they will be champions for change and facilitate smoother transitions to the marketplace.

Which policies do you think have had the greatest impact on the petfood industry?

The industry came together in about 2012 to address the ongoing issue of salmonella in petfood. Our member petfood manufacturers, through AFIA’s Pet Food Committee, decided that food safety was not a competitive issue as we were all working toward the common goal of protecting public and pet health. Our members began working together to share best practices for the reduction of salmonella in kibbled petfood, mainly how to properly test for it and safely hold products until the test results were received, and that close industry collaboration has never wavered.

That was a turning point in the issue, where the prevalence via the FDA’s sampling decreased, as did the number of pet food recalls.

What are some of the major actions the AFIA has taken to support the petfood industry?

The US pet food industry is an important sector that feeds over 135million of America’s dogs and cats using over 500 safe and nutritious ingredients to provide the variety of pet food and treats that today’s consumers desire for their pets. The AFIA has supported the industry in its regulatory compliance since the first model petfood regulations emerged in the 1950s. Since then, we have not only kept our members apprised of changing rules and regulations impacting their businesses, but we have also offered education programs, such as the annual AFIA Pet Food Conference, and networking opportunities to continually advance the field.
