In fact, according to the 2017 survey, 24 per cent of all households, had a dog in residence, the largest proportion of pet owners across all UK households. The equivalent figure for cats was 17 per cent, the second largest proportion of UK households. There are, however, some interesting regional variations. The region with the largest proportion of households owning a dog is Northern Ireland where the figure is 38 per cent. In sharp contrast, the region with the lowest proportion of households owning a dog is London with just nine per cent of households. This is intuitively understandable; opportunities for walking dogs are more restricted in the metropolis compared to those in more rural environments. The same would appear to apply to felines where the national figure

comes in a wide range of both intensities and duration. Each of these parameters impacts upon both the diet design and feeding strategy. Matters are complicated further by the fact that much of the research and information so far on feeding the active dog is based on the extremes of activity, examining such sports as Greyhound or endurance Husky racing. Practically, the range of activities that dogs participate in is varied, for example dogs retrieving game in the hunting field, farm herding dogs, military dogs, mountain search and rescue dogs and those taking part in events such as agility or canicross, an event where owners run with their dogs. We also need to recognise that diet is only a part of the picture. You need a dog that is bred for the event, of appropriate body

(Canicross or trail runners), police work and racing, rather than the extremes of Husky racing. Counterintuitively, such activities may not need extremes of specialised diets, but would benefit more from carefully balanced moderate changes to dietary nutrient content and, more importantly, changes to how the dogs are fed. Development of a specially designed feeding programme for a food around a particular event could give manufacturers another tool to differentiate their product. Some studies indicated that feed restriction prior to and during an event improved performance and that carbohydrate re-supply immediately following an activity can help restore muscle glycogen for sprint events (Wakshlag, 2013). Equally, studies reveal that overfeeding or an overweight dog is detrimental to performance.

Climate has less of an effect, but is worth noting that hot weather can be as demanding on the dog’s energy expenditure as cold, with each degree of temperature above or below the thermo-neutral zone for the dog accounting for an additional bodyweight -0.75.°C-1. For most dogs this zone equates to between 20-30°C (NRC, 2006) although for Huskies it is estimated that the lower critical temperature is <0 °C.

How Much Protein? Adequate protein supply is important to help maintain muscle mass and integrity as well as blood albumin, haematocrit and the immune system. Contrary to popular opinion, it is much less important as an energy source. It is suggested that around 24% of dietary energy from protein is ideal for sprint dogs. There is some good evidence to suggest that excess protein intake can reduce sprint performance (Hill et al 2001). However for endurance dogs >30% of dietary energy should come from protein. Such protein is often referred to as needing to be of good quality and digestibility and this being essentially of animal origin. Indeed some studies do indicate that plant based animal proteins do not support the canine athlete as effectively as animal sources (Wakshlag et al 2003, Middlebos et al 2009). However, these for endurance. In terms of the fatty acid profile, it is reported that the long chain

It may be more helpful if this smaller contribution also provides fermentable CHO to help support gut function and reduce the incidence of stress related diarrhoea. For dogs running hard repeatedly on successive days for between 5 minutes and 4 hours there may be benefits to each subsequent performance event from feeding 1.5g of maltodextrin or similar carbohydrate per kg of body weight within 30 mins of completing the exercise. This will help to replenish muscle glycogen; such a strategy should be before feeding the normal diet. In practical terms for the pet food manufacturer, this leads to the opportunity for the design and development of specialist, active dog treats/food supplements to match the dog’s activity (Reynolds et al, 1997, Wakshlag et al, 2002, Clero, et al, 2015)

with appropriate amounts of essential fatty acids will ensure that dogs have good skin, paw pad and coat quality. The skin of the body and the paw is the first organ that comes into contact with the environment. It is therefore important that optimal nutrition promoting skin health is provided to working and exercising dogs. During exercise, production of reactive oxygen species and other free radicals can increase, which if increased above the capability of the antioxidant system results in the condition of oxidative stress (Hinchcliff et al, 1998). Oxidative stress is an imbalance, or excess of the pro-oxidants/free radicals in relation to anti-oxidants present in a system. Oxidative damage to cell membrane lipids, proteins and DNA may alter athletic performance. In sled dogs, those with higher levels of plasma vitamin E were found more likely to finish a race.

for pet foods. This is particularly true for botanical ingredients, botanical extracts and other functional ingredients. Lead times may be extended from far flung suppliers and distance also makes the relationship more difficult to manage closely. Long, convoluted supply chains also pose a challenge in ensuring that a pet food business can adequately demonstrate they understand their supply chains and also to be confident in the consistent quality of their ingredients. This again is where a progressive premix company will be able to provide significant expertise. Due to the changing requirements of pet premix customers, the portfolio of materials purchased by a premix manufacturer is continually growing as is the global reach of the supply chain. Integrated supply chain management to promote transparency, ethical sourcing and sustainability is something that the modern premix manufacturer can provide to its customers.

Premix design is based on the principles of nutrition including food technology and marketing requirements. Key global food trends are increasing the constraints placed on pet premix design but these can be surmounted where the correct relationship between premix manufacturer and pet food producer is in place. A few of the key trends are:

Game Mixes It

Game Engineering is well-known for its system supply and installation expertise and with their superbly equipped workshops and qualified staff will often manufacture most of the components – storage silos, holding hoppers and support structures – which comprise a system. What are perhaps not so well known are their machinery manufacturing capabilities. Some years ago, Game Engineering decided to design and build their own twin-shaft Paddle Mixer thereby passing on significant savings to their customers. Today there are two types available, the twin-shaft paddle mixer and the Ribbon Blade mixer There are six models in the GPM Paddle Mixer range giving a batch spread from 400 litres through to 2,000 litres. Key attributes with every model include their ability to produce thoroughly homogenous mixes quickly, consistently and without product degradation or heat build-up. The paddle mixers are based on a twin drum design with two counter rotating shafts. Carefully profiled paddles are attached to each shaft at specific angles to guide the material along the shaft in a direction which is dependent on the rotational direction of that shaft. The paddle assemblies overlap and the pre-determined low speed of the counter rotating shafts generates a precise peripheral velocity at the tip of the blades, this action suspends the bulk of the material being mixed in a near weightless condition which enables a total mix. Once the mix has been completed a bomb-door arrangement discharges the batch into an under-hopper and onwards for further processing or packaging. The body, endplates, shafts and paddles are manufactured from 304 grade stainless steel to current EU Standards. The Ribbon Blade Mixer is an incredibly flexible design which ensures that a customer takes delivery of machine that precisely suits their application. The Ribbon Blade mixer can be supplied as part of a three tier mixing system, consisting of a top receiving hopper, the mixer itself and a discharge under hopper. Customers then have a

choice of discharge mechanisms (either bomb door or a single central slide), a choice of drive systems, construction from either mild steel or full stainless steel and can opt for the fitting of a sparge pipe for liquid additions. With a capability of being able to handle batch capacities from 1200 litres through to 6,000 litres, the Ribbon Blade Mixer is a batch machine for handling the blending of pre-weighed ingredients for a multitude of industries. Both the GPM Paddle mixers and Ribbon Blade mixers have been designed for continuous batch mixing and, as a consequence are robust and built to last.

pet food industry becomes clearer. Put simply, pet owners want food that is safe for their pets to eat; in this context it should be free from both malicious/intentional and accidental contamination. To achieve this, raw material suppliers, pet food manufacturers and, indeed, retailers need to consider HACCP, VACCP and TACCP in their food protection plans. The discussion so far has focused on pet food safety from the perspective of ensuring the health and wellbeing of our pets.

system is seen when we consider the damaging financial effects of food safety failure on our industry. This is illustrated in Table 2. Whilst this table shows elements of the financial cost it does not show the recall and disposal costs, the damage to the Brand Equity of the company and the reputational damage to the pet food industry. The overall “cost” of failure is therefore significantly greater than these figures indicate. When carrying out routine food safety / quality audits at one of my pet food ingredients clients, I am occasionally asked by the managing director “Are we there yet?” I am always sorry to disappoint this senior manager, that due to emerging threats there is no defined destination and that on-going support from senior management is required. Historically the destination might have referred to safe food / ingredients produced using HACCP as the management system. However, the world we live in is constantly changing as new threats and opportunities arise. To respond to this changing environment, we need to evolve our strategy to encompass HACCP, VACCP and TACCP. Importantly we also need to be aware of threats that might be just around Table 2: The cost of food safety failure in the pet food industry (Source pet food industry trade press)

Hydronix launches two new digital moisture sensors Hydronix is delighted to have launched two brand new microwave moisture sensors. Using our already proven digital technology, our new sensors are manufactured from food safe materials specifically for use in Animal Feed, Grain, Rice, Nuts and Liquids. The Hydro-Mix HT is a high temperature sensor that will measure moisture in materials that have a process temperature of up to 120°C. This makes it ideal for installation before or after dryers or in mixing systems.

Hydro-Mix XT

Hydro-Mix HT

The Hydro-Mix XT is a digital moisture sensor that unlike other systems available in the market comprises a single unit that contains all on-board functionality such as signal processing, smoothing and averaging. This sensor has an external seal enabling it to be installed in dusty or liquid processes or applications, from 1 Bar Vacuum to 5 Bar pressure. Both of our new sensors come with fixing plates that makes them easy to install flush with the internal wall in drying, ducting, conveying and mixing systems. Hydronix also offers the Hydro-Probe XT sensor. This is designed

for applications that require the sensor to be placed into the flowing material such as at the outlet of a silo or in the neck of a storage bin. All Hydronix sensors are designed for use in flowing materials with readings being taken 25 times per second as the material passes across the ceramic sensing face. With Digital Inputs/Output, a choice of measurement modes, free configuration and calibration software and a global sales and support network, Hydronix is already the supplier of choice for many OEM equipment manufacturers, system integrators and end-users.

can be placed inside the box if required. Two boxes are filled simultaneously layer by layer, and when complete, exit the gantry palletiser as a pair. They are subsequently separated and fed individually to an automatic rotating arm stretch wrapper equipped with a power pre-stretch film carriage and film tail gripping, heat sealing and cutting. Power pre-stretching of the wrap film is crucial on this application to allow careful control of both the wrapping and lay-on forces. Conveyors are equipped with inverter drives for controlled and gentle movement, particularly of taller, narrow loads. After individual wrapping, the two half Euro pallets are regrouped at the slave pallet station. The half pallets are raised together and a Euro pallet from a dispenser is placed beneath. The grouped load is then returned to the stretch wrapper and given a final wrap to secure and unitise the two half pallets as one load which is then conveyed to the unloading position for warehousing or distribution. The whole system is controlled by PLCs connected by a network, which allows programme selection for the whole line from one position. This simplifies the operator’s tasks, reduces the risk of set up errors and cuts the changeover time from one product to another. As is standard for Concetti the line was completely built and underwent a full factory

acceptance test in Italy before despatch. The unusual combination of mixed products and Düsseldorfer pallets has big advantages for the discounters. With minimal handling in store and safe and easy manoeuvring by pallet truck along narrow store aisles they contribute to efficiency and help to reduce stock management costs. Boxes can be printed in colours and carry a logo for great brand recognition. And be it bags or cartons the customer has a convenient choice of two products from the same stack. It’s an idea that could easily catch on. George Page, Production Director at IPN said, “The whole system has been a great success. It has eased workload, reduced stress, increased flexibility, given customers greater choice, and will eventually Above: A tailor-made palletising and de-palletising system

*HPP (High Pressure Pasteurization); not all frozen/refrigerated products are subjected to HPP and thus may be contaminated. Even if HPP is employed, products can be re-contaminated after being removed from the pasteurization step. **The freeze-dried process would appear to yield good stable products with little concern about biological hazards. However, the freeze-drying process is very gentle and products rarely surpass 27°C which means potential survival of microorganisms as this process does not necessarily achieve sterilization.
