Water Activity as a Measure for Feed Quality Control: Part II

Food safety is one of the main buzz in the present time. As of now food safety was limited to only human and pet food with little concern of livestock feed. But with time now consumers are not only becoming more aware of the quality aspects of livestock rearing but also on the quality of inputs being fed to reared poultry & cattle. One important aspect of prepared feed quality is the stability of the final product.

Changes in physical, chemical or microbiological properties of feed can be considered loss of stability. Water activity (A_w) is one of several important parameters that affect stability of livestock feed. Water activity is a measure of the free moisture in a foodstuff. It is also defined as the quotient of the water vapor pressure of the substance divided by the vapor pressure of pure water at the same temperature.

The water activity scale extends from 0 (bone dry) to 1.0 (pure water) but most foods have a water activity level in the range of 0.2 for very dry foods to 0.99 for moist fresh foods.

Water activity need not to be confused with moisture content. Moisture content is the combination of free and bound moisture. Free moisture can be explained as water that is available to participate in physical, chemical and biological reactions.

Water activity plays a vital role in the microbial stability of ingredients and final livestock feeds. Bacteria, molds and yeast require water for growth; and every microorganism has a minimum water activity below, which it will not grow.

In the previous part, we discussed the Water Activity stability in terms of degradative reactions rates and microbial growth limits as a function of water activity along with different scenario of damages due to uncontrolled water activity. This is the concluding part of the article.

Water activity may affect physical properties such as moisture migration, texture and etcetera.

Moisture migration occurs when there is a aw difference between components or with the surrounding environment as the system comes to an equilibrium. Undesirable textural changes can result from moisture migration in multicomponent product. Water migrates from region with high aw to region with low aw until an equilibrium of aw is achieved but the rate of migration depends on structure or diffusion process (o’Connor et al., 2017). Effect of moisture migration with humidity on aw can be illustrated in moisture sorption isotherm as shown in Figure 7. Figure 7 shows how aw changes as water is adsorbed into and desorbed from a product at equilibrium relative humidity and constant temperature. In practice, this moisture sorption isotherm maybe impractical to use as it is complex and unique for each product. Besides, the relationship between moisture content and water activity changes when temperature varies and also when there are any variations in material composition with a modifying effect.

adsorption and desorption isotherms (Airaksinen, 2005).

Water activity affects the biochemical reactions and physical properties of the product.
Uncontrolled a_w in soybean meal (SBM) storage can cause non-enzymatic browning reaction during processing and moisture migration in the storage. Due to moisture migration, it leads to caking of SBM in storage. Besides, water activity has the ability to influence both the rate and color of non-enzymatic browning reaction, which is also known as Maillard reaction. Maillard reaction (MR) is a biochemical reaction between reducing sugars and amino acids to form Maillard reaction products (MRP) and further progress to Advanced glycation end products (AGEs). MR takes place even at room temperature but at a slower rate. The rate of reaction increases when time and temperature increases, and at a humidity of 40-70%. MR is mostly responsible for the deterioration in protein quality, especially lysine is the most susceptible amino acid (Tanaka at al., 1977). SBM is very vulnerable to MR over storage in a hot and humid tropical condition. SBM has high percentage of lysine, arginine, cysteine and tryptophan which easily react with reducing sugars, resulting in MR and the degradation of amino acids (Ibáñez et al., 2020). Since SBM is widely used as a feed ingredient in feed formula, MR is an unavoidable issue in moist heat feed pelleting process. There are inconsistencies in performance of birds fed with mash and pelleted feed which is highly due to the quality of SBM (Araba and Dale, 1990). A good indicator to determine the degree of MR is the colour change in product. Generally, as water activity approaches 0.70, the rate of Maillard reaction increases. When aw is higher than 0.70, Maillard reaction slows down because the reactants are diluted by too much free water.

Figure 8. Picture on the Left shows caking issue in SBM stored in a flat warehouse. Picture on the Right shows the effect of different stages of Maillard reaction in SBM.

Shipment of corn gluten meal in containers

A trial was done to monitor the effects of moisture migration and aw in corn gluten meal (CGM) during shipment from USA to the Pacific Rims.

Moisture movement creates stickyness, caking, and mobility issue on mealy material as Figure 12 (Left). However, when aw is controlled, the corn gluten meal has a very different free-flowing characteristic as observed in Figure 12 (Right).

Figure 12. Picture on the Left shows caking in corn gluten meal whereas Right picture shows free flowing corn gluten meal.

What is worst is that aw has increased substantially with free moisture movement, and the material gets moldy upon reaching port. See Figure 13 (Left). The treated CGM prevents free moisture movement, and aw is hence controlled at a safe level maintaining freshness and the original quality at point of loading, shown in Figure 13 (Right)

Figure 13. Picture on the Left shows crusted top layer and mold in corn gluten meal whereas Right picture shows free-flowing corn gluten meal inside the container. — Figure 13. (Left) Crusted top layer and mold in corn gluten meal. (Right) picture shows free-flowing corn gluten meal inside the container.

Quality integrity of palm kernel pellets

This trial was done to investigate the complain of staleness of products from Malaysia shipped in container to Japan and Korea. 2 MT of fresh products from the same production batch was used with 1 MT Control PKE pellets was bagged and another treated 1 MT PKE pellets bagged. All the bags are stacked on pellets and stored at the hottest areas in production for 90 days to simulate a challenge.

After 90 days, the result was astonishing. Figure 13 shows clearly the difference between control and treatment. The control group (Figure 14 Left) look discoloured, with a stale appearance, and without the aroma of PKE. The treatment group (Figure 14 Right) has a very fresh appearance, maintaining its original quality, and still has a strong PKE smell.

This is another classic case of moisture movement and activated aw compromising the chemical stability of the product. Nutrients and lipids are degraded which explains the poor quality of the control group.

Figure 14. Picture (Left) shows the control group with non-treated PKE and Picture (right) shows the treated PKE. — Figure 14. Picture (Left) shows the control group with non-treated PKE and Picture (right) shows
the treated PKE.

Water activity and moisture content in processed poultry pellet feed

A feed trial was conducted to investigate the addition and capturing of water on the processed pellet feed quality, for starch cooking/gelatinization, data shown in Figure 15. To show the effect of working on a program to capturing water, as in getting moisture from water added at the mixer plus microscopic moisture from steam into the feed chemistry. A process addressed as “positive mash hydration” (This is for the sole purpose of starch granule swelling and sufficient degree of protein denaturation). The result in starch gelatinization is later captured by feed imaging, indicating a loss of birefringence.

With the treatment feed, notice the spike on aw after water has been added at the mixer. Interestingly, the finished feed of the treatment group has a higher moisture content, but water activity is lower compared to the control group. The capturing of moisture for the purpose of starch gelatinization which in turn lock up the hydrolyzed water used in the process of starch swelling/cooking indicates the positive chemistry changes of feed processing.

Figure 15. Feed Quality parameters that were recorded during a pelleted feed trial.

Figure 16. Picture on the Left is the control group with aw of 0.68 and moisture content of 10.14%. Picture on the Right is the treatment group with aw of 0.59 and moisture content of 10.86%. — Figure 16. Picture on the Left is the control group with aw of 0.68 and moisture content of 10.14%.
Picture on the Right is the treatment group with aw of 0.59 and moisture content of 10.86%.

Conclusion

Water activity is a critical parameter in controlling the quality of feed and feed ingredient as it is a reliable indicator and predictor of chemical reactions and microbial responses in the industry. This is how we need to manage and control aw with proper grain storage, shipment of feedstuff, feed processing on both pellets and extruded feed, and handling of mash feed. This will dictate how well we face up to the challenges in keeping the quality of grain over storage, and the processed feed in post-production. A proven approach to managing and controlling aw has been established with proven results. Chasing down a moldy problem with mold inhibitors is like attempting to save a building on fire with extinguishers. The building still gets burnt and ravaged.

Winter management in Poultry Farming

Poultry rearing is an art as well as a science and management plays most crucial role in deciding profitability of this business. It has been observed in past several years that high market rates of broiler meat & eggs are observed only in those times when rearing is very difficult due to harsh climate and thus, demand is more than supply. Therefore, it is very important to understand and implement the best management practices in such harsh climate.

Author: Dr Milind Rainchwar — Dr Milind Rainchwar,
Technical Service Manager – South Central Asia,
Novus International

Every region in India has different climatic challenges and variable climate extremes and thus management practices differ between different parts of country. But almost all parts of India experience three to five distinct seasons across the year.

Winter is one of the seasons which presents very harsh temperature extremes and maintaining liveability and production becomes very difficult without taking extra measures. Management in winter is very difficult and often described as double edges sword, as a very perfect balance is required between climate management and ventilation management. Similarly, a very careful decision making is required to reduce cost of production and to provide healthy environment at the same time. It requires ample of experience to understand the economic feasibility of cost involving management practices.

Chickens are unable to maintain body temperature in young age and although they improve their tolerance to cold with age, they cannot perform well when ambient temperature drops below 20 degrees Celsius and start exhibiting stress and drop in productivity. Failure to provide optimum temperature very frequently results in high mortality, high disease incidence and drop in performance.

Although ways of practicing the management in harsh climate may differ slightly across region, the basic principles remain same. Below listed are few basic principles which may guide proper decision making.

Proper temperature and humidity suitable for the age is always required
Proper ventilation to provide fresh air and removing gases inside house is always required
The rearing surface and bedding material should be always warm and dry
The drinking water should be maintained at suitable temperature to promote water intake
The feed & feeding practice should help bird to maintain their body temperature, metabolism, and osmo-regulation

To achieve these goals, following practices are implemented across country

External heat source is provided to keep the poultry shed warm and dry
False ceiling is often used to reduce the volume of shed
Various types and layers of curtains and jute bags are used to insulate the farm
Round brooding is often practiced when spot heating is done

As stopping the air flow becomes necessary to maintain temperature, it is very difficult to remove the gases like ammonia and to keep bedding material dry in winter. These challenges affect the respiratory, hepatic, and gut health directly.

The wet litter and humid conditions provide a very suitable environment for gut pathogens like Coccidiosis and Clostridium. The stressed and immunosuppressed birds become easy target for these gut pathogens and therefore, very high-performance losses are observed due to poor gut health. It is a well-known fact that body only gets that part of nutrition, which gut retains. An unhealthy gut loses a lot of nutrients which are necessary for weight gain and egg production. The major part of poultry immune system is also situated in gut. Thus, healthy gut is key to a developed immune system.

While managing good managemental practices, essential needs such as Proper feed and water is an utmost need to optimise performance during this difficult time. Gut health compromise always leads to poor performance and thus loss in business. Different feed additives play crucial role in maintaining and improving gut health such as Protease, NSPase Enzyme, Probiotics, Essential oils, Organic Acids, etc.

Serine Protease, A broad spectrum protease when added in the feed improves the digestibility and absorption of Amino acids which otherwise are the food for pathogens in the hind gut like Clostridium, Salmonella, etc. This Protease thus enables the improved digestion of Nutrients and reduces the pathogenic load and helps to improve litter condition.

Serine protease has other benefits as well. It has good impact on neutralisation of trypsin inhibitor, an Antinutritional factor in Soybean. Use of Serine Protease also helps to reduce the allergen proteins like Lectins, B Conglycinin by significant amount which otherwise causes the gut irritation. Hence, Proper use of Protease in winter leads to improved litter quality with better absorption of nutrients.

NSPase when added in the feed improves the absorption of nutrients and helps to reduce wet litter condition. Improvement in litter quality leads to the less damage by pathogens.

Organic Copper has the strong impact on litter quality in winter (copper is antifungal in nature). It helps to improve the Clostridium cluster IV & XIVA which are responsible to increase the Lactobacillus count in the gut and maintains or improve microflora through competitive expulsion. This, then enables to improve the litter quality.

Organic Acids such as Coated Benzoic acids helps not only to reduce pathogenic bacteria such Clostridium, Salmonella as well they help to improve Lactobacillus count in gut through increase in Clostridium clusters IV and XIVA which are responsible for Increase in Lactobacillus count.

Essential oils are considered primarily Digestive enhancers apart from their immune function. They help to digest the nutrients in early stages effectively where endogenous enzyme is not active fully. Also, they impede quorum sensing, thus acts as Antibacterial in nature too.

Addition of God organic Acids such as formic Acids, Propionic acids in water to keep water acidification at par is key to improve water quality. Water intake is always a concern in winter. Thus, Effective use of Organic acids along with water Sanitisers to improve water quality and intake should always be considered in winter season.

Below are some pics showing the brooding in Winter and Impact of Winter on gut Health if not managed well…

Inclusion of cocktail enzymes – key to unlock hidden nutrients in poultry diets

The major cost in any system of poultry production is feed which accounts for up to 70 % of total cost per bird. The upsurge feed cost has been a major constraint in profitable poultry production in most of the developing countries. In order to cut down the feed cost, cheaper and non-conventional feed ingredients are sometimes in use which contain a higher percentage of Non-Starch Polysaccharides (soluble and insoluble/crude fiber) along with starch. Non Starch Polysaccharides (NSPs) are polymeric carbohydrates that differ in composition and structure from starch with beta linkage (Morgan et al., 1995) and possess chemical cross-linking among them therefore, are not easily digested by poultry (Adams and Pough, 1993).

Impact of NSP and Phosphorous:

A portion of NSPs is water-soluble which is the culprit for forming a gel-like viscous consistency in the intestinal tract (Ward, 1995) and reduces gut performance. Predominantly water-soluble NSP like arabinoxylans,ß-glucan,ß-galactoside which belong to the pentosan group, are assumed to be the factor responsible for the increase in viscosity of ingesta. These pentosans also critically increase the water intake by the birds leading to unmanageable litter problems caused due to wet and sticky droppings. This deteriorates the hygienic conditions and carcass quality of birds.

Impact on Environment:

In areas with intensive poultry production, the phosphorus output is terribly high, leading to environmental issues like eutrophication. This happens as most of the phosphorus contained in typical feedstuffs is in the form of plant storage phytate, which is not digested by birds.

In order to overcome this problem, use of enzymes in poultry is a growing trend and is going to be established as an inevitable resource in formulating and making balanced and nutritious diets. Enzymes are proteins in nature in biological systems. Their function is to catalyze and accelerate the rate of a reaction but are not themselves altered during the process. Enzymes are non-living organisms and are not concerned about viability or cross-infection/cross-contamination. They are stable at 80-85 degrees centigrade for a short period of time.

Another vital function of enzymes is that the rate of an enzyme catalyzed reaction increases with increasing substrate concentration, to the point where there is no more response and the enzyme is said to be saturated. So, we need to match the amount of enzyme with the quantity of substrate present in the feed grain (Acamovic and McCleary, 1996).

Enzymes are classified into 2 types based on their production site ie., inside the body and from an external source:

Source of enzyme :

Enzymes are produced in large scale in a controlled fermentation process where either yeast or specific bacteria strains are used. While these microbes grow and multiply in media, release enzymes. Bacteria like Bacillus subtilis, Bacillus lentus and Bacillus amyloliquefaciens, Bacillus niger are commonly used to produce enzymes.

Mode of action:

Enzymes are substrate-specific and work with the basis of lock and key methods. Once lock and key matches it releases the nutrients and searches the other substrate to release nutrients.

Some enzymes and substrate present in feed grain

Scope for cocktail enzyme:

The cell wall of cereal or legume grain provide tensile strength, protect them against mechanical and osmotic stress .The main substance responsible for rigidity is non-starch polysaccharides (NSPs) like cellulose microfibrils, hemicellulose and pectins. Some of the commonly used ingredients in poultry feed are corn which have NSP level of 9.7%-10.3% of DM and is 91% insoluble (Bach et al., 1997),wheat have NSP of 10.2%-11.9% of dry matter and in which 19.5%-21% soluble fiber(Simon et al., 2015) and Soybean meal (SBM) have 19.6%-21.7% NSP of DM, with 29% soluble fibre (Dierick et al., 1994).

Due to the presence of this substance, they form a dense, flexible and sometimes rigid matrix which may deplete nutrient digestion of ingredients. Effect of cocktail enzyme will have better effect on such feed formulation:

Zanella et al., (1999) reported better ileal N digestibility which may be due to improved solubility and digestibility of dietary protein, reduced secretion of endogenous proteins and also a reduction in ileal microbial load.
Morgan et al., (1995) reported that use of enzyme supplementation of wheat-based diets significantly reduced foregut digesta viscosity of birds.
Partridge and Wyatt 1995 stated that increased availability of carbohydrates for energy utilization in birds with association with increased energy digestibility.

Conclusion:

The use of exogenous enzymes as a feed additive has hastily expanded. In the last two decades, extensive studies have been conducted to study the effects of feeding exogenous enzymes on the performance of poultry. The economic and social advantages of enzymes are well established and therefore the way forward for feed enzymes could be a bright one. However additionally the right enzyme cocktail for a selected batch of a feed ingredient will permit the formulation of better rations using an extensive range of ingredients. Any developments in this field must eventually improve the welfare of chickens, reduce the production of wastes and preserve resources.

Food Safety Impacts Animal and Human lives

If animals aren’t vaccinated, or they face health difficulty, they will turn into unsafe food and they will produce disease filled products. Thus, this will have a major impact and influence on our wellbeing and safety, which is why its highly important to protect poultry and livestock health, to secure their well-being and ours in return.

Unsafe food poses global health threats, endangering everyone. Infants, young children, pregnant women, the elderly and those with an underlying illness are particularly vulnerable. According to the world health organization: “Every year 220 million children contract diarrheal diseases and 96 000 die. Unsafe food creates a vicious cycle of diarrhea and malnutrition, threatening the nutritional status of the most vulnerable.”

On this note, Mr. Ahmed Aufy the Marketing Manager at Elanco, a global health company that work to improve the health of animals through innovative products and services for pets and farm animals around the world, has shared some valuable intel when it comes to food safety and its impact.

When we asked Mr. Ahmed Aufy about his standpoint and expertise on how Food Safety impacts animal and human lives, he mentioned:

“Food safety is an intact approach which is designed to protect consumers from any hazards related to Salmonella infection and/or contamination in their food.”

He added on his answer, a brief about Human salmonellosis disease by saying that:

“Food-borne Salmonella poses a significant risk to human health where at global level impact millions of people’s lives.” He continues: “Data shows that 94 million humans get infected every year with about 155 thousand death.”

This brought us to ask him a very important question revolving around the Regulations impact and their Poultry disease’s management system, which he graciously answered as follows:

“It varies from country to another one. In some countries in EU, regulations are there and even advanced at all production and supply chain levels just to minimize the risk of infection. Regarding MENAGSE, regulators and authorities are giving special focus these days on the subject, we see a trend of ongoing investigations/discussions from several countries in the gulf region and even outside.”

Mr. Ahmed also continued to mention about the importance of live vaccines on counteracting Salmonella disease, by saying:
“Live salmonella vaccines represent more powerful solution as they work at the level of cell-mediated immunity where it can be used from day 0 which means earlier protection.”

Have you heard of the Lion Code? Perhaps you’ve read about its impact on Salmonella’s control History in the United Kingdom. Mr. Ahmed discussed with us the terminolody and he identified it as follows: “Lion code is a Britain’s specific method to stamp the eggs where it gives the message to the end users that the stamped eggs are safe for consumption.”

He continues:

“It is kind of regulations that were created at breeders, hatcheries, layers, packaging, feed mills and retailers with very extensive protocols just to avoid or minimize any kind of Salmonella infection or contamination. By other meaning protecting the entire production, supply and market chain to provide healthy and safe food.”

In addition of being the gold sponsors for MEVMAS 2022, Elanco will be discussing Food Safety and Dr. Ahmed Aufy will be there as a speaker where he will be having an in-depth speaking slot followed by participating in panel discussion where answers will be provided to all of the questions of the attendees at the Middle East Veterinary Medicine and Animal Science Conference, which will be from February 7-10, 2022; online.

Leveraging EC Houses for Bird Performance & Energy Efficiency

An Exclusive Interview with Poultry TRENDS magazine, Mr. Akshay Dhumal, Managing Director, Dhumal Industries shares why adoption of Environmentally Controlled ( EC) houses is a must for the industry and how this changes production levels and increases efficiency.

Excerpts of the interview is as under:

Q. How do you see the trend of environmentally controlled sheds in India?

There is widespread awareness about EC Houses all across India now. Majority of the Breeders are upgrading to Environment Control.

The medium & large farmers will plan their own farms where along with enhanced bird performance they will also get better uniformity & biosecurity. These kinds of houses are also very well suited for processing.

Q. The initial investment for EC sheds is high, how do companies like yours help producers move towards EC houses?

It’s a myth that Initial Investment in EC Sheds is high with changing modern poultry scenario and land cost. The two most important parameters about rearing a bird in EC and Farming generally as well is the volume of birds one can grow & the initial investment in terms of COST PER BIRD. Both of these parameters are only viable in EC and modern farming, the cost per bird is well justified in terms of the ROI and enhanced bird performance that we achieve in these kinds of houses.

Dhumal Industries is the only company in India and among few in the world that has developed technical expertise in structures as well as the equipment inside which enables our team to design & execute complex EC houses end to end. Our integrated approach means we can integrate the structure and housing equipment in such a way that it optimises bird performance, improves bio-security, and helps the producers transition towards EC Houses in an efficient & effective way.

The work that companies like us have put in over the years have ensured that the Initial Investment in EC Sheds is kept to an optimal and the farmers reap the benefits in terms of a faster payback on their investment.

Q. Is it possible to design an EC house according to the budget and needs of the poultry farmer?

It is possible to design and economise an EC house according to the budget and needs of the poultry farmer without compromising on the quality of the product. An example is our Ecolite series of houses, wherein we have developed a high tensile pre galvanised EC compatible steel structure along with curtains or panels especially for the individual farmer who grows chicken for an integrator on a fixed growing charge. Considering a standard fixed charge growing scenario in India, the grower can payback his investment in 3.5 years & establish a stable income source and means of sustainability for years to come.

Similarly, it is possible to build our Ecolite EC Houses for Layers farmers within a budget and also incorporate our unique plastic metal composite cages which makes it more ergonomic for the birds & farmers, and facilitates improved operational and automation levels.

Q. How important is the adoption of EC houses for the industry at the moment? Will this dramatically change production levels?

Efficiency, Bio security & Green Technology with animal welfare will be key for our poultry Industry going forward. Poultry – chicken & eggs is one of the best, cleanest and most difficult to adulterate kind of protein source available to us. Dhumal takes immense pride to work in an Industry where we are solving a real problem and playing our part to make proteins available to the masses at a competitive price comparable to other protein sources.

Adoption of EC Houses is already a trend for the poultry industry at the moment and it has dramatically changed production levels and brought in efficiency.

Breeding Sustainability – Aviagen Illustrates CO2 Reduction Contribution to Global Poultry Industry

January 24, 2022 – HUNTSVILLE, Ala. – How can the food production chain meet the needs of the world’s ever-growing communities without overwhelming the planet? Aviagen® addresses this question through “Breeding Sustainability.” Sustainable poultry breeding contributes to a decrease in carbon emissions through a continuous improvement in biological efficiency, fitness and welfare traits. Feed Conversion Ratio (FCR) or the rate at which feed is converted to body weight is a key indicator of biological efficiency and has the greatest direct impact on the industry’s carbon footprint.

Due to an FCR improvement of 1.5-2.0 points per year, Aviagen contributes to a 1% year-on-year carbon footprint reduction. This video tells the story of the “FCR Advantage” through a balanced breeding approach, resulting in a yearly reduction in the poultry industry’s greenhouse gas (GHG) emissions.

Feeding the world, preserving the planet – The FCR advantage

The global population is growing. The United Nations (UN) estimates just over 8.5 billion people by 2030, and the world will face the challenge of providing food for everyone. The OECD-FAO Agricultural Outlook 2021-2030 predicts that meat production will need to rise by 44 million metric tonnes by 2030, with half of the increase supplied by poultry. The food industry currently contributes close to 25% of the world’s annual GHG emissions, and of this amount, poultry meat is responsible for about 6%.

As a result of FCR improvements, the modern broiler generates 50% less carbon footprint than the bird in 1970, and fast forwarding to 2030, the bird of the future will create a 15% lower carbon footprint than the bird of today.

In 2020, 133.3 million metric tonnes of poultry meat were produced globally, at a carbon cost of 6 kilograms CO2 for every kilogram of meat. That translates to 800 million tonnes of CO2.

“To illustrate the impact with a hypothetical example, based on our FCR gains, if every bird were an Aviagen bird, this amount would be reduced by 8 million metric tonnes per year. To put it in perspective, this is the carbon equivalent of flying around the world on a Boeing 747-400 5,906 times,” explained Aviagen’s Director of Global Genetics Dr. Santiago Avendaño. “As a poultry breeder, we are at the beginning of the food production chain, and we take our responsibility of contributing to the sustainability of the entire industry seriously. We have worked for years to breed efficiencies that make poultry production more sustainable, while at the same time advancing bird health, welfare and performance. Because we care about the planet, our customers and the communities they serve, we are committed to continually breeding for sustainability for decades to come.”

Breeding a greener future

Aviagen has made Balanced Breeding one of its top 5 corporate commitments. Balanced Breeding simultaneously promotes the Environmental, Economic and Social pillars of sustainability, helping farmers around the world feed their communities with a healthy, affordable and sustainable source of protein, while breeding efficiencies that help to preserve our planet for today and for generations to come.

Aviagen Applies Latest Technology to Give Best of Both Worlds

Aviagen Applies Latest Technology to Give Customers and Internal Teams Best of Both Worlds for In-Person and Remote Support

New remote support high-technology solution is perfect complement to local personal support

Jan. 4, 2021 – HUNTSVILLE, Ala. – Aviagen^® teams in Asia Pacific, Latin America and North America have combined their talents to create a new hybrid platform for heightened customer service and internal flock management. The new solution is made possible by a combined package of the latest in bonded cellular networking, mesh Wi-Fi, Augmented Reality (AR) headsets, specialist software and other technology. Thus, through live-streaming capabilities, for example, customers will be able to bring Aviagen experts virtually to the farm, hatchery, or any area of their facility where they need help on a pressing issue.

“Being there for our customers to ensure their continual success is our number one priority, and this new suite of tools is meant as a complement to the world-class support our customers get from their local teams. Thus, they could have immediate remote access to our array of specialists, both local and global, in addition to regular face-to-face personal support,” explained Aviagen CEO Jan Henriksen.

The end goal — Strengthening customer service

As a result of the new virtual solution, no matter where they are located on the globe, poultry producers can have the opportunity to receive rapid advice on performance improvements and solutions to their daily challenges, directly from Aviagen’s team of global specialists in genetics, veterinary service, nutrition, flock management, incubation and hatching, and more. This solution optimizes organizational efficiency by providing on-the-spot answers to pressing issues within a poultry operation.

“Aviagen is passionate about continually improving our service to customers,” explained Aviagen President of North America Marc de Beer. “While AR and Virtual Reality (VR) headsets are largely associated with gaming and entertainment, we have found an ideal application in business, which will elevate our support efforts by providing the perfect complement to one-on-one care and collaboration from our local Aviagen customer teams.”

“We are committed to leveraging the latest and most advanced technology to champion the success of our customers,” added Rafael Monleon, Business Manager for Asia Pacific. “Our new solution will enable our Aviagen experts opportunities to collaborate with customers in remote locations, resulting in faster solutions to challenges and best-practice advice to optimize their operations.”

These advanced tools demonstrate our innovation, not just as a breeding company, but also as a technology business,” concluded Ivan Lauandos, President of Aviagen Latin America.

An added bonus – Increasing internal efficiency and collaboration

Aviagen will also use this technology to improve information and idea sharing, as well as training for its internal teams located in Asia Pacific, Latin America and North America. In fact, the company has already started applying this innovation internally, and will introduce it to customers in early 2022 based on a structured region by region roll-out.
