Combating inflammation in dogs with micronutrients

Submitted by aledford on Wed, 10/20/2021 - 08:19

Inflammation has become one of the hottest health topics in recent years, and for good reason. Inflammation is the basis of any disease that ends in “-itis” — which, unfortunately, accounts for a large percentage of presenting medical conditions.

What is inflammation?

In and of itself, acute inflammation is not a bad thing. Inflammation is the body’s way of responding to any type of foreign invader or event. The immune system initiates an inflammatory response in order to handle anything and everything, from a wound or infection to bacteria and viruses.

There are five cardinal signs of inflammation:

  1. Redness
  2. Heat
  3. Swelling
  4. Pain
  5. Loss of function

All of these signs indicate that the body is working to repair any damaged tissues and remove the potential danger.

Inflammation goes wrong when it becomes chronic, meaning that it is a longer-term issue in which the immune system responds inappropriately. In this case, the body is often on a loop of constant low-level inflammation that involves excessive levels of inflammatory cytokines and other proteins that can cause cellular damage at a microscopic level. This chronic inflammation is what puts us and our dogs at a higher risk of developing serious health conditions, ranging from immune diseases in dogs (such as inflammatory bowel disease, hypothyroidism, etc.) to skin and coat issues to heart disease and osteoarthritis. In many cases, chronic inflammation is a common cause of premature aging and a shorter lifespan because of its impact at the cellular level.

What causes chronic inflammation?

Chronic inflammation in dogs can be caused by environmental toxins or irritants, obesity and, perhaps most notably, an unhealthy diet. While it can be difficult to control or remove every inflammatory agent in today’s world, the good news is that science has made strong links between digestive tract health and inflammation — and nutrition is something that we definitely have the power to change.

In both human and animal medicine, the case for using natural, anti-inflammatory ingredients as a means to combat chronic inflammation is growing quickly. In the animal industry, this field of science is often referred to as immunonutrition, or the study of how specific nutrients can impact the immune system.

For example, any food that your dog may be allergic or sensitive to can cause inflammation, as can synthetics, toxins and other chemicals. In contrast, some anti-inflammatory ingredients in pet food diets include omega-3 fatty acids, pro- and prebiotics and other functional nutrients, such as antioxidants.

What are the signs of chronic inflammation in dogs?

A chronic immune response in dogs can manifest as:

  • Low energy and fatigue
  • Unwillingness to walk, play or exercise
  • Weight management issues (i.e., dogs becoming overweight or obese or suddenly losing weight)
  • Itchy, flaky or dry skin, which may lead to infection
  • Pain and discomfort
  • Loss of appetite
  • Vomiting, diarrhea or gastrointestinal (GI) distress

The link between the gut microbiome and inflammation

A dog’s gut microbiome is immediately affected by its diet, as food acts as the fuel for the living organisms in the digestive tract.

As such, our responsibility as pet lovers is to provide our furry companions with nutrients that play a long-term role in their health. In senior pets, especially, inflammation and the buildup of oxidative stress can negatively impact the aging process and can even lead to premature aging.

The ability to prevent premature aging — or “inflammaging,” as it has been coined — through the diet is key to canine longevity.

For dogs, science has learned that the smallest ingredients, or micronutrients, often make the biggest difference. One example of the micronutrients that are gaining attention from both scientists and consumers is pro- and prebiotics for senior pets. A 2019 study in senior beagles looked at the microbiome-related effects of a control diet versus a diet that included NVGEN, a proprietary blend from Alltech that includes prebiotics and other gut health promoters.

The dogs that were fed NVGEN showed higher levels of the bacteria that are associated with a healthy digestive tract, while the dogs fed a control diet had higher levels of the bacteria associated with inflammatory conditions, such as rheumatoid arthritis.

Additionally, the dogs that were fed the diet that included NVGEN displayed significantly lower levels of C-reactive protein, a standard measurement of inflammation in the body. Feeding a diet that contained NVGEN resulted in a decrease of the amount of C-reactive protein to a normal level — which is a big deal for promoting healthy aging in dogs!

The anti-inflammatory pet plan

Inflammation is one of the most insidious symptoms of many chronic health conditions in pets. Inflammation can begin to manifest in pets in their younger years and can negatively affect the aging process as they become seniors.

An anti-inflammatory lifestyle is important for dogs at every life stage and includes:

  • Managing the dog’s weight
  • Feeding an age-appropriate, high-quality diet
  • Regular exercise and activity
  • Proper levels of mental stimulation (without creating excessive stress)
  • Protecting and supporting the microbiome

The bottom line is that promoting a healthy inflammatory response and immune system in pets starts in the gut. Protecting the GI tract with ingredients such as the Alltech NVGEN pack is a critical step in improving pet food diets and, as a result, boosting the longevity of our beloved dogs.

Successful pig production without zinc oxide: How to thrive and survive

Submitted by aledford on Mon, 10/18/2021 - 09:40

From June 2022, a zinc oxide ban, prohibiting the use of therapeutic doses of zinc oxide (ZnO) in animal feeds to control post-weaning diarrhea in piglets will come into effect in the European Union (EU). Although ZnO can still be used as a feed additive after this date, it will only be allowed at the maximum permitted dose rate of 150 ppm total dietary zinc. Before we discuss why all EU pig producers need to be ready to rear their pigs without pharmacological levels of ZnO by 2022, it is important to understand why the use of high levels of ZnO in swine nutritional diets has increased dramatically across the globe in recent years.  

Where it all began

At weaning, piglets are subject to a multitude of stress factors over a very short period that contribute to gastrointestinal tract and immune system disturbances. These factors can be:

1. Nutritional: Abrupt dietary change from sow milk to a dry, pelleted, predominantly vegetable-based diet formulation.

2. Environmental: Moving to new nursery accommodation with different housing conditions.

3. Health-based: Loss of passive immunity from the sow.

4. Physiological: Abrupt maternal separation, being handled and transported and mixing with unfamiliar pigs from other litters.

Because the pigs are under such stress, the early post-weaning period is typically characterized by poor growth performance (e.g., reduced feed intake) and increased susceptibility to post-weaning diarrhea.

Traditionally, pig producers relied heavily on antibiotic growth promoters in pre-starter and starter feeds to control pathogenic infections (mainly caused by enterotoxigenic E. coli) and improve pig growth performance in the first few weeks after weaning. This was common practice until various governmental bodies banned the use of antibiotics as growth promoters, such as the European Parliament in 2003, due to growing concerns over increasing levels of antimicrobial resistance (AMR). The continual spread of AMR has dangerous consequences for not only animal but also human health.

Following this ban, pig producers had to seek alternatives to maintain optimal gut health and to reduce this post-weaning performance drop. As a result, the use of high levels of ZnO in piglet feeds (2,000 ppm or higher) became more widespread and was seen as common practice in the swine industry. It was shown to be an effective and relatively inexpensive tool for preventing and controlling post-weaning diarrhea, with subsequent improvements in piglet growth performance, feed intake and digestion. Although the precise mode of action of ZnO against post-weaning diarrhea in weaned piglets is not yet fully understood, it is believed to be related to a significant improvement in both intestinal morphology (i.e., improved structure and function) and nutrient digestion and absorption. 

Why ban pharmacological levels of ZnO?

Though there are several benefits of using ZnO in piglet feeds (preventing post-weaning diarrhea, maintaining health and performance, etc.), recent reports have highlighted its environmental impact, and we became aware of its contribution to the spread of AMR. It is, therefore, not surprising that regulations around its use are changing and why the EU decided to ban the use of pharmacological levels of ZnO in June 2022. However, it is not all bad news for the European pig industry, as there are several potential benefits to the upcoming ban on ZnO. Some of these benefits are:  

1. Reduced environmental pollution

As previously mentioned, there are environmental concerns over the continued use of high levels of ZnO. This is primarily because zinc accumulates in soil after zinc-rich pig manure is applied to the land as an organic fertilizer. These high levels of zinc in the soil and surface water are deemed an environmental pollutant and health risk and may also impact the absorption of other trace elements, such as iron.

2. Preventing antimicrobial resistance

Recent studies and reports have demonstrated ZnO’s contribution to the increase of AMR, as high levels of ZnO may increase the proportion of multi-drug-resistant E. coli in the intestines of piglets.

3. Avoiding zinc toxicity

Zinc remains a heavy metal and is, therefore, toxic to many living organisms, including pigs. Studies show that prolonged use of pharmacological levels of ZnO may negatively affect piglet health and performance, as demonstrated by a marked decrease in feed intake. 

4. Preventing nutritional interactions

High levels of ZnO can have a negative effect on phytase activity (an enzyme that is included in piglet feeds to enhance digestion), whereby the phosphorous cannot be released from phytase due to the formation of a complex of zinc with P-phytate. When ZnO is removed from piglet feeds, it should have a positive effect on phytase efficiency.

5. Avoiding changes to gut microbial composition

The use of pharmacological doses of ZnO may also cause changes to the gut microbial composition of piglets during the early post-weaning period by suppressing the growth of beneficial bacteria, such as Lactobacilli. Such changes may negatively affect intestinal development and health in young piglets.

What is in store for pig-producing countries outside the EU?

Canada: Until recently, ZnO was typically included in piglet feeds at 2,500–5,000 ppm in Canada. However, Canada is now in the midst of imposing similar restrictions to that of the EU, which will see the level of ZnO allowed in piglet feeds reduced down to nutritional levels of 350 ppm.

China: The use of high levels of ZnO also came under scrutiny in China, and, as a result, China has drastically reduced its level of authorized dietary zinc supplementation, going from 2,250 ppm to 1,600 ppm in 2018.

United States and some Asian countries: It is very likely that the United States and some Asian countries will also implement similar restrictions on the use of pharmacological levels of ZnO in piglet diets in the near future. Although there are no restrictions currently in place in these regions, it is vital that swine producers avoid over use and start the process of working towards ZnO alternatives so that they are prepared when a ban inevitably comes into effect.

Until recently, ZnO represented one of the vital nutritional strategies for preventing and controlling diarrhea in young piglets and the associated detrimental post-weaning ‘growth check.’ However, increasing concerns over environmental pollution and contributions to the spread of AMR have led to an EU ban on the use of high levels of ZnO in piglet diets. Adopting a holistic strategy that encompasses optimal nutrition, management, biosecurity, health and welfare practices will be key to ensuring that pigs can thrive and survive in a post-ZnO era.

Receiving your stocker or feedlot cattle with ease

Submitted by aledford on Mon, 09/13/2021 - 16:16

The receiving period can be a stressful time for cattle. Recently, during the Alltech ONE Ideas Conference, Dr. Carlo Sgoifo Rossi gave a presentation titled “Receiving With Ease: Minimizing Stress During the Adaptation Phase.” Dr. Sgoifo Rossi is currently an associate professor in the department of veterinary science and technology for food safety at the State University of Milan. Utilizing his perspective and knowledge of the European beef production system, Dr. Sgoifo Rossi shared some information about the various considerations related to stress and adaptation that producers should keep in mind when implementing feeding programs and management practices.

When cattle are undergoing a transition like weaning and receiving, they experience stressors, including:

  • Transportation
  • Interactions with other cattle
  • Interactions with humans
  • Changes in nutrition

These stressors can have a major impact on cattle and can lead to such issues as changes in their immunodeficiency, reduced rumen motility, altered nutrient absorption, increased nutrient requirements and an upsurge of mineral excretion by the kidneys.

Receiving stress can lead to BRD

Regarding immune function, one common but highly concerning issue is bovine respiratory disease (BRD), which can strongly affect the performance of cattle. As illustrated in Figure 1, cattle who arrive and are treated for BRD can exhibit a decrease in average daily gains. It is also important to understand that animals who experience BRD often produce meat with lower marbling and quality grades. Considering all of these factors, mitigating BRD is important not only for the animal’s quality of life but for the producer’s bottom line and the consumer’s satisfaction.

Appropriate sanitary conditions make a difference

While the health of newly arriving animals is impacted by their location of origin, it is also greatly affected by the sanitation and management of the receiving location. According to Dr. Sgoifo Rossi, “The type of vaccination, the type of antibiotics used (and) the type of anti-parasitic product can affect the sanitary conditions of our animals.” Dr. Sgoifo Rossi encouraged producers to approach sanitation with an understanding of their specific herd and facilities and posited that, for some beef production systems, the strategy of going “all-in and all-out with cleaning and disinfection” is the best approach.

Nutrition is critical in the cattle business

When talking about management, we must be sure to properly feed and rehydrate the cattle upon arrival. Ensuring that clean drinking water is readily available and being conscious of the arrival diet are both crucial. Feeding the arrival diets in small amounts multiple times a day is recommended, as this will reduce competition among the animals, giving each of them an opportunity to receive adequate amounts of protein and energy. Arriving cattle can sometimes be considered high risk, making this a critical period for helping them recover properly and get back to normal rumen functionality.

Studies have shown that the appropriate arrival diet should have a crude protein and dry matter composition of less than 13%.

“Several studies show that if we improve the crude protein level of adaptation diets or the energy level of adaptation diets, we increase not only the incidence of morbidity but also the severity of morbidity and, consequently, the risk of mortality,” Dr. Sgoifo Rossi said.

Additionally, with the arrival diet typically being richer in forage and higher in fiber, reducing the chop length of the fiber will also reduce the likelihood that animals will sort through the ration. This is important, because sorting can cause cattle to eat too much starch or protein, which can lead to fluctuations in the pH level.

Consider all of the nutritional needs of arriving cattle

Unsurprisingly, it is also important to consider the nutrients available in the arrival diet. Providing new-arrival animals with the proper nutrients will improve their immunity, digestibility, and energy and protein balances.

To recover rumen and immune system functionality in newly arrived cattle, it is important to consider diets that include the following:

  • High levels of digestible fiber
  • Yeast
  • Mannan oligosaccharides (MOS)
  • Slow-release nitrogen
  • Vitamins
  • Minerals

As mentioned previously, the arrival period is so critical for getting cattle right. Vitamins, minerals and other supplements can help improve their feed and can be fundamental in helping these cattle adapt to their new home. In his presentation, Dr. Sgoifo Rossi mentioned that studies have shown that organic zinc and selenium, live yeast and mannan oligosaccharides can be huge players in the reduction of morbidity and mortality in these potentially high-risk cattle.

Too often, producers and nutritionists underestimate the importance of these ingredients, leading to negative results. Dr. Sgoifo Rossi shared a study completed in Italy that examined the mineral status and mineral plasma levels of cattle after arrival. This trial focused on the evaluation of various mineral levels in the blood immediately after arrival. As shown in Figure 2, 83% of new-arrival beef cattle were in a deficient or sub-deficient condition regarding their copper availability, and 30% displayed deficient or sub-deficient zinc availability and reserves.

Weather can be a stressor

Weather can play a significant role in cattle stress, and more thoughtful management practices should be implemented with the weather in mind. Spring, summer and fall are less of a concern when it comes to sanitation management, but winter is a critical period for sanitation. Producers often forget to consider the relationship between temperature and humidity during the winter and how it can lead to cold stress. This can create a potentially dangerous environment for cattle and can result in increased incidences and more severe cases of BVD. As shown in Figure 3, low-temperature, high-humidity environments can create a risk area where sanitation conditions are an issue, leading to a slower adaptation for arriving animals.

As previously mentioned, there are challenges leading up to and during the receiving period that can result in the highest risks of morbidity and mortality. Implementing the proper sanitation and vaccination protocols, providing sick animals with antibiotics, being proactive about their nutrition, and understanding which management practices to use based on the origin of your cattle, as well as their transportation details and the time of year, are all effective ways to mitigate any potential challenges associated with receiving cattle.

3 keys to innovative nutrition for puppies and kittens

Submitted by aledford on Fri, 03/26/2021 - 09:11

If your pet food company produces balanced diets for puppies and kittens, you know that it is not always easy to differentiate yourselves from the competition.

With numerous options at the neighborhood pet food store and on the increasingly popular e-commerce sites, new pet parents are often bombarded with decisions. Should they go with raw diets for puppies? Dry or wet food for kittens? High-protein diets? Vitamin and mineral supplements?

Ultimately, you want pet consumers to choose your nutrition programs. Let’s look at three ways to make sure that your puppy and kitten diets stand out on the shelf.

1. Beware of the “high-protein” hype.

Yes, puppies and kittens have nutritional requirements that include high protein and calorie levels, but be wary of oversimplifying this message.

Protein sources are not created equal, and claiming that a food is “high protein” is not as important as the levels of essential amino acids that are present in the diets of young kittens and puppies.

Protein requirements for puppies and kittens are really requirements for higher levels of high-quality protein. Do your best to convey to consumers that your pet food brand contains excellent-quality protein from a traceable source that specifically meets the needs of a puppy or kitten.

Furthermore, taking a step backwards, a growing animal’s body also requires nutrients that support its cells’ ability to produce proteins.

Nutrients such as nucleotides, which are the molecules that make up an animal’s genetic material (DNA and RNA), are in high demand throughout the animal’s life, but never more so than during the growth phase, when the gastrointestinal and immune systems are developing quickly.

Nucleotides are found in high levels in the mother’s milk, but young companion animals still have an increased need for nucleotides, even after weaning. Research has shown that nucleotide supplementation in puppies increases their immune systems’ capacity to respond to dangerous diseases, such as parvovirus.

Arming your pet food with the organic molecules and amino acids that really matter for growth and development in puppies and kittens, such as those found in Alltech’s NUCLEO-SACC™, will deliver real results for your consumers and, ultimately, the pets they love.

2. Make it palatable.

This may seem fairly obvious, but reduced food consumption in growing kittens and puppies can lead to major growth and developmental problems.

It is important to communicate to pet owners that while the desired growth rate for both puppies and kittens is “slow and steady” so as to prevent the over-development of their musculoskeletal systems, young animals will grow the quickest in their first 6 months of life and need to be fed in line with those needs.

Building your puppy and kitten diets with highly palatable ingredients, such as glutamic acid, can help promote feed intake in a controlled manner. Additionally, using a body condition scoring system can help to guide nutrition for kittens and puppies. Teaching pet owners how to use body conditioning can help prevent under- or over-development.

For both dogs and cats, body condition is typically assessed on a scale of 1 to 9, with 1 being severely underweight and 9 being obese. An ideal body condition for cats and dogs is between 4 and 5, where their ribs can be easily felt but not seen and a waistline can clearly be identified.

In growing companion animals, body condition is likely to change more rapidly, and there could very well be some “awkward” growing phases. All is well. The important thing is to keep their body condition in mind so that you can adjust their diet as needed before anything gets too out of whack.

Overall, helping consumers understand that growing pets require a balanced diet that meets their increased nutritional demands without overloading their body systems is key. Designing pet food diets that are palatable and therefore encourage consumption means that consumers are less likely to overfeed an imbalanced ration to compensate for what is missing, and that could have a hugely positive downstream effect on their pets’ long-term health.  

3. Focus on functional nutrients.

Functional nutrients are those that may provide health benefits beyond the basic nutritional requirements. Regardless of what type of pet food your company produces, be sure to include functional nutrients that can assist with young companion animals’ proper growth and development.

One functional nutrient that often goes unmentioned is inositol. Inositol is a sugar that is found naturally in the body. Inositol supports proper nerve and muscle function, in addition to optimal cell membrane development. Because of its role in cell structure, it is important for growing animals to have quality sources of inositol in their diets.

Additionally, ensuring that your young companion animal pet food contains 100% organic trace minerals (including copper, zinc, manganese, iron and selenium) will provide a huge boost to your nutrition program. Trace minerals are especially critical during growth to ensure the proper development of all of the animal’s body tissues. Organic trace minerals have been shown to be absorbed and utilized at higher rates in the body than their inorganic counterparts, which means that development and performance can be improved just by feeding your brand’s diet!

Summary

Ultimately, you care about your pet food diets because you care about the puppies and kittens who will be eating them.

Adding sufficient levels of functional nutrients — such as essential amino acids, nucleotides, inositol and glutamic acid — in addition to high-quality essential trace minerals will make your pet food brand the best it can be while also ensuring incredible results for your customers’ new family members.

How cattle vaccination and nutrition connect

Submitted by aledford on Mon, 03/08/2021 - 08:43

Proactive cattlemen are good cattlemen. They have the foresight to combat the inevitable stresses and other challenges their cattle will face. They know that weaning, transportation and other prolonged periods of stress can have a negative impact on immune function and, ultimately, the performance of their animals. So they act to mitigate that stress and, in turn, any health problems their beef cattle are facing. They know that prevention is cheaper than treatment, and they want to see their cattle thrive. Preventative health management practices are key for healthy cattle.

Vaccinations and nutrition have a symbiotic relationship in terms of maintaining healthy immune functions in cattle. While quality nutritional programs are the bedrock of healthy immune function, both nutritional and vaccination programs are important for successful preventative health management on a cattle operation. Preventative health management focuses on promoting an animal’s natural immunity and minimizing the negative growth responses associated with stress and other health challenges.

The role of vaccination

Vaccinating your cattle stimulates their immune systems to produce antibodies that specifically work to combat disease-causing viruses or bacteria. After vaccination, a healthy immune response should translate to a memory of those specific pathogens for the immune system. This memory ensures a rapid response if the animal is exposed to pathogens it has been vaccinated against and allows the animal to avoid infection. Disease challenges vary between different geographies, so it is important to work with your local veterinarian to develop vaccine protocols, as they can identify and walk through the specific needs of your operation.

Although your needs may vary based on your herd and geography, there are a few vaccines that we typically consider crucial for beef cattle, such as a scours vaccine and vaccinating for the bovine respiratory syncytial virus.

Implementing a beef vaccination schedule

While vaccination is generally important, establishing a well-constructed beef cattle vaccination schedule is crucial for vaccine success. One part of that plan — that is, the timing — can make the difference between failure and success. Vaccinations should be timed so that peak levels of antibodies are present when the animal is at the highest risk of infection. Keep in mind that peak levels of antibodies take several weeks to manifest following vaccination, so you’ll want to plan ahead.

The stage of the production cycle will determine the type and timing of the vaccine.

  • Pre-calving: A scours vaccination should happen during late gestation so that the highest levels of antibodies are present in the colostrum. A new calf’s immune system is weak, leaving it susceptible to disease and reliant on colostrum to provide it with much-needed antibodies and protection.
  • Pre-breeding: For added protection for replacement heifers and cows, it might make sense to implement a pre-breeding vaccination protocol. This should be done around 45 days before you are hoping to breed. 
  • Bulls: Keeping your bulls protected may mean implementing an annual vaccination program. Similar to your cows and replacement heifers, these vaccinations may be most effective for bulls around 45 days before breeding.
  • Weaned calves: Vaccinations should be given a couple of weeks before weaning so that peak antibody protection is achieved during feedlot arrival. With weaning, transportation, a new environment and mingling with a new group, this time in a calf’s life is the perfect storm for sickness. Vaccination provides calves with some protection as they start this new stage of their lives.

These programs and protocols are only as effective as they are managed. Poor animal health status at vaccination, improper vaccine handling and inadequate nutritional status can all lead to vaccine failure. A failed vaccine costs more than just the amount of product you had in the syringe; it can lead to loss of gain or even death throughout an entire group of calves. Likewise, it is important to understand that vaccines do not guarantee 100% protection and may only provide protection for a period. Even so, can we increase the effectiveness of the vaccine through proper nutrition?

The role of nutrition

Meeting an animal's nutritional requirements is essential for the proper development, maintenance and function of its immune system. Among the other health benefits good nutrition provides, it can also bolster the effectiveness of vaccines and provide longer-lasting protection for cattle. To achieve a nutritional status that supports immune responses, a cattle nutrition program must include energy, protein, trace minerals and vitamins.

  • Energy: Immune responses require an abundance of energy. When cattle are exposed to a disease, their immune systems work hard. In terms of the energy hierarchy, an immune response comes before maintenance and production energy. However, shifting energy to the immune response will decrease the nutrients available for growth or maintenance and can cause a reduction in body condition in dams and reduce growth in feedlot animals.
  • Protein: Proteins are used to produce antibodies. Since the goal of vaccination is to increase the production of antibodies, a protein deficiency can result in substandard antibody production. As with energy, shifting protein from growth to immune function can negatively impact animal performance.
  • Trace minerals and vitamins: The amount of trace minerals and vitamins needed in the diet varies based on the age, role and geography of the cattle, but both vitamins and minerals play an essential role in immune function. Deficiencies in one or more of these nutrients can lead to reduced antibody production.

Nutritional needs at different life stages

Just like with vaccines, the nutritional needs of your cattle will vary based on your specific herd and geography. Factors that can contribute to the nutrition discussion on your operation include the type of facilities your cattle have access to, the feedstuffs used and whether your cattle have experienced health issues in the past. The most important factor, though, is the current life stage of your cattle, as this will dictate the most basic nutritional needs that should be met.

  • Newborn calves: As mentioned above, calves are born with a high susceptibility to disease, requiring them to rely on colostrum to acquire those all-important antibodies. Calves should have a healthy gut from the very start so that they can better absorb the nutrients in colostrum and, as they transition to creep feed, maximize their potential for big gains.
  • Weaned calves: Maintaining a healthy gut in your calves through weaning is crucial to supporting their gastrointestinal integrity, aiding in vaccine success during the receiving period and keeping them healthy in high-stress situations.
  • Cows: The needs of the cows in your herd can vary based on their age and their current stage in the production cycle. Depending on the forage quality, cows may need mineral supplementation for optimum health, immune function and reproductive success.

Herd vaccination programs require an investment of both time and money, and quality nutrition is essential to safeguarding your investment. Talk with your veterinarian about putting together a solid vaccination and nutrition program for your operation. Remember: Proactive cattlemen are good cattlemen, and prevention is cheaper than treatment.

3 stages of optimizing piglet nutrition for gut health

Submitted by lkeyser on Tue, 11/03/2020 - 13:47

Newborn piglet care is a challenge on every farm. In the early stages of their lives, these young animals are more susceptible to health issues that would never affect older, more developed pigs. These challenges can come from all angles, as disease-causing organisms (such as bacteria, protozoa and viruses) are present in every part of the farm environment. From the sow to farm personnel, equipment, bedding and feed materials, there is no escape from these threats.

Even with the appropriate biosecurity measures in place, as piglets grow, they encounter other health-impacting sources. Changes in the diet, for example, can cause digestive disorders, manifested as diarrhea and failure to thrive and grow.

Due to the exposure to and consumption of external, potentially disease-bearing entities, such as water, feed and bedding, maintaining proper immunity is essential. Optimizing gut structures and microbial populations is vital for young animals, as it establishes the basis for their ongoing health and development. Piglets have very specific needs to establish good gut health and functions and to limit disease development. Providing the best gut health in young piglets can be achieved through various feeding interventions. Here are three crucial stages of developing good gut health in piglets to help put you on the right path.

1. Optimize colostrum from the sow

While in the womb, pigs benefit from the fully developed immune system of the sow. However, once born, piglets do not take any of these immunities along with them, essentially starting from scratch. To help encourage good gut health, the producer's task is to ensure that the newborn piglets have a good supply of immunoglobulins (Igs). These act as the first line of defense for young piglets, helping them to build their immune system to fight off the challenges they face in their environment. The best source of Igs is the colostrum supplied by the piglet’s mother, making it a crucial first step in optimizing gut health in piglets.

After the initial colostrum intake, piglet immunity status tends to diminish, making them more vulnerable to disease, which commonly manifests as:

  • Diarrhea
  • Dehydration
  • Poor milk consumption

In addition, the switch from a milk-based diet to a grain-based diet at weaning means that their gut structures and microbial populations need to adapt quickly. This difficult period is referred to as the “weaning gap” in terms of health and immunity and occurs somewhere between 14–21 days of age.

To ensure that piglets continue to get the support they need and have a strong base to help them through the diet transition, the expression of Igs in the sow’s colostrum must be optimized. This can be achieved by including prebiotics and mannan-rich fractions (MRF) in sow gestation diets. Feeding trials (Spring et al., 2006) have shown that doing so increases the levels of all Igs in the colostrum and in the blood of the subsequent piglets that receive it.

2. Promote good gut health directly

As well as using them to optimize the mother’s colostrum, pre- and probiotics can be administered orally to piglets, promoting the development of the correct bacterial balances within the gut, establishing the best basis for future disease prevention, and maximizing health and growth.

Long-established research studying MRF has shown that it binds to the projections on the surface of disease-causing microbes, preventing them from attaching to the gut wall, which they need to do to reproduce, leading to harmless removal in feces. In addition, this binding activity interacts with the immune system in the gut, promoting faster responses to any disease threat. Multiple trials have shown that this activity of promoting better gut health increases feed intake, digestion and growth and improves feed conversion.

3. Use high-quality creep feeds

When piglets reach the age to begin weaning, creep feeding is introduced to prepare their digestive systems for the change in diet. This is another opportunity for the producer to bolster the young animal’s gut health by formulating creep feed with the best-quality raw materials, processed to maximize digestion and supplemented with proven feed ingredients. These can include:

  • Nucleotides to facilitate gut tissue development
  • Enzymes for maximum digestion
  • Chelated minerals to ensure the best uptake and establish tissue mineral reserves during times of stress

These types of diets will ease the difficult period during weaning and will not compromise the gut environment, keeping disease at bay. Nucleotides are the building blocks of DNA and are essential for young animal development. They have been shown to significantly increase the growth of gut tissues and are important for repairing and preventing damage to the gut wall. A more robust gut structure is necessary to withstand the change from milk to grain-based feeds at weaning, when the erosion of essential structures (villi) for nutrient absorption can occur.

Seed, Feed, Weed

Over the last 40 years, Alltech has conducted extensive research studying gut health and has designed several gut health management programs that focus on supporting animal performance from birth by promoting favorable bacteria communities, building natural defenses and maximizing growth. The Seed, Feed, Weed (SFW) concept is one such program that is designed to modify the gut microbial population to establish favorable and more diverse microbial populations after birth. This program utilizes the advice above to help establish and maintain a beneficial and diverse gut microbiome in piglets. The SWF program supports gut health in piglets by:

  • Seeding the gut with favorable organisms: It is vital to “seed” the intestine with the correct bacteria as soon as possible after birth. The first organisms to colonize the gut will determine the composition of the flora by creating the micro-environment necessary to establish a complex microbial community and optimal architectural development. With the right intestinal microflora now in place, piglets show improved early growth, feed conversion, uniformity and livability.  
  • Feeding the favorable organisms: In addition to “seeding” the gut with the correct pioneer species, it is crucial to enhance the capacity of favorable organisms to colonize and rapidly dominate the microbial community in the small intestine. Once a beneficial microbial community and intestinal ecology is established, the villi will flourish. This step is critical for piglet health and feed efficiency because the healthier a piglet’s villi, the more efficiently nutrients will be absorbed.
  • Weeding out the unfavorable microorganisms: The gut can also contain harmful pathogenic microbes (e.g., enterotoxigenic Escherichia coli), which can damage the intestinal villi. It is, therefore, important to “weed them out” before they can attach to the gut lining and replicate enough to cause disease. By blocking the attachment mechanisms of unfavorable organisms with a type-1 fimbria blocker, their capacity to compete with the favorable organisms (e.g., Bifidobacterium and Lactobacillus) in the gut is reduced. Minimizing the gut’s exposure to these harmful microbes will help to improve the animal’s natural defenses and shorten its recovery time from disease.

"Seed Feed Weed"

Figure 1. The Seed, Feed, Weed concept is designed to modify the microbial population in the gut to establish favorable and more diverse microbial communities after birth.

Providing solutions for each step of the Seed, Feed, Weed process, Alltech offers a range of products for both the sow and their young that help to optimize piglet nutrition and support gut health and development. These include:

As they start life, baby pigs are extremely vulnerable. Any change in their environment potentially exposes them to a whole new group of pathogens, which can limit their performance. Furthermore, as they mature over the weaning period, they are typically moved into new environments and exposed to other equipment, animals and people. Ensuring that the best gut health is established as early as possible is key to limiting disease, increasing health and welfare and maximizing growth. This is essential for the young piglet and helps to ensure optimal lifetime performance and profitability for producers in a sustainable manner. The use of gut health management programs will also play a pivotal role in helping producers work toward antibiotic- and ZnO-free production.

How to tackle the most common aquaculture challenges

Submitted by aledford on Fri, 07/31/2020 - 12:31

The unpredictable nature of the current environment — including the increasing prices of raw materials for aquaculture, the reduced availability of animal-based proteins, using fish meal for fish feed, disease risks and health pandemics — is an ongoing concern, and the industry will be impacted by all of these issues for years to come. It is time for us all, as an industry, to adopt new strategies and learn to co-exist with new norms. This will, no doubt, be a test for each stage of the food chain, but there are some long-term approaches that the industry can take to help increase our profitability and sustainability.  

The ultimate objective for producers

Without a doubt, the most important goals for producers in the aquaculture industry are to:

  • Produce healthy fish in the most sustainable manner.
  • Reduce the use of marine ingredients.
  • Aim for increased growth.
  • Reduce operational costs.

Attempting to improve weight gain and lower the feed conversion ratio (FCR) puts increased pressure on the digestive tract to function with the highest efficiency. Considering this, maintaining the health and welfare of fish and shrimp will still be critical for efficient production. Stress from the rigors of production, disease resistance, age and feed, combined with external factors — such as temperature, salinity and pH — can cause imbalances in the gut, potentially leading to disease.

Diets in the aquaculture industry have changed significantly over the last number of years and will continue to be modified and improved. From a sustainability perspective, there is an ever-growing need to reduce fish meal and fish oil in aquaculture feeds. Feed ultimately provides energy and nutrients to support the development of the species. Providing the correct balance of feed is crucial for protecting against foreign pathogens and is critical for the system to function optimally. Formulations must be highly digestible, and each ingredient must add value to and enrich the diet to impact performance. As feed ingredients are derived from several different sources, significant planning, research and development can lead to more sustainable, economical and responsible feed solutions. When considering any change to an existing diet, the nutritional requirements of the species must be met. Each aquatic species has a different set of nutritional requirements, and they can fluctuate depending on their stage in the lifecycle.

Aquafeed is comprised of a selection of natural feed ingredients, including:

  • Essential amino acid sources
  • Essential fatty acids
  • Vitamins and minerals

Imbalances in the diet will lead to a lack of required nutrients, which will have a direct impact on the performance and welfare of farmed fish.

The gut is the key to success

To fully protect fish and shrimp for long-term success, protecting them right from the start is crucial. Their first point of interaction with outside world — the skin, gut and gills — play a vital role in protecting the animal against the environment and its internal physiology. The gut is a complex system of tissues and organs that play an essential role in all interactions related to these functions:

  • Food digestion and absorption
  • Metabolism
  • Defense mechanisms
  • Immune response

An unhealthy gut cannot defend itself. A healthy gut, on the other hand, can digest and absorb the maximum amount of nutrients, providing the most benefit for the farmer. 

Importance of maintaining and improving gut integrity

  1. Choose the correct selection of ingredients to prevent gut inflammation.
  2. Increase the growth of good bacteria.
  3. Create a solid foundation for health and growth.

The use of mannan-oligosaccharides (MOS) in diets has been shown to improve gut performance. However, their function can be altered depending on the strain of yeast, the fermentation conditions and the processing methods.

Recent trials carried out with trout, carp, catfish, tilapia, seabass, sea bream, sole and salmon show the effectiveness of MOS in aquaculture species, promoting a healthy growth rate and improving intestinal morphology. The effects of different concentrations of dietary MOS in carp (Cyprinus carpio) included higher weight gains as well as improved FCR, productivity and immune parameters (Zhou and Li, 2004). Improvements in growth performance and reduced FCR and mortality have also been observed in MOS-treated juvenile common carp (Culjak et al., 2006) and rainbow trout (Staykov, 2007). Similar results have also been observed in European seabass (Torrecillas et al., 2006; Ramirez et al., 2016).

Bio-Mos® is a unique product derived from a selected strain of Saccharomyces cerevisiae yeast using a proprietary process developed by Alltech, Bio-Mos is incorporated into animal diets to support overall animal performance. Effective during all phases of growth, Bio-Mos is designed to feed the gastrointestinal tract, thereby maximizing performance and profitability. Bio-Mos has been shown to maintain gastrointestinal health and integrity, contributing to increased growth and lower FCR. It has also displayed an ability to increase the absorptive surface area supporting the immune system, and  stimulating the natural defenses and health status of the animal.

"Bio-Mos enhances gut structure in aqua, supports barrier function, increases intestinal surface area for fish, and supports overall digestive function of fish"

The inclusion of Bio-Mos in the diet improves gut morphology by increasing the microvilli density and length, leading to an enhanced absorptive surface. A report completed by Dimitroglou et al. (2007) demonstrated the effects on the gut morphology of several species. Similarly, in European seabass, an increased number of folds was noted, indicating a larger surface area for nutrient management (Torrecillas et al., 2015).

More and more fish farmers around the world are finding that including Bio-Mos and Actigen in their strategic feeding programs provides a successful and cost-effective solution to their animal health problems. Getting this aspect right as early as possible in the production cycle will ultimately benefit fish performance in later life.

Reducing costs will always be an important element in the viability of any farmed species; however, it is clear that the positive impact of solid gut health will affect production and performance and help mitigate the challenges faced by farmers worldwide. Providing fish with quality nutrients, backed by innovative technological solutions based on sound research and development, plays an important role in ensuring financial success.

Controlling Salmonella and Campylobacter in poultry

Submitted by aledford on Wed, 07/22/2020 - 08:53

Any cook, whether a professional chef or at-home hobbyist, will tell you that when dealing with raw meat, especially turkey and chicken, food safety is key. From improper food storage to cross contamination on the cutting board, the opportunities to cause sickness and food poisoning are plentiful.

According to the World Health Organization (WHO), each year, foodborne illnesses:

  • Affect 1 in 10 people.
  • Cause 33 million healthy life years to be lost.
  • Result in 125,000 deaths of children under five.

When these illnesses are profiled, it becomes apparent that Campylobacter and Salmonella are huge issues, accounting for 38% and 35% of illnesses, respectively, despite there being a plethora of other potential pathogens. They can both be found in multiple species but are commonly discussed in the poultry industry due to how they interact with birds. Consumers are told that thorough cooking of food will stop the transmission of these pathogens, but early steps can also be taken to control Campylobacter and Salmonella in poultry production and processing.

The journey of infection

While they can cause huge human health problems if they invade the human gastrointestinal (GI) tract, these bacterial organisms are normally asymptomatic in the bird. Campylobacter infection reaches a rapid growth phase in the higher body temperature of birds, which is why birds act as a big reservoir for infection. The bacteria are then passed on to humans, where they invade the GI tract. Salmonella is transmitted both horizontally (bird to bird) and vertically (from mother to chick through the egg). Both pathogens bind to attachment sites on the epithelial cells of the gut wall.

Go with the gut

Gut health and the microbiota can have a significant impact on pathogen colonization and, as a result, transmission. The microbiome is a complex subject, but it is well-documented through research that the microbiota and the gut interact with each other. The microbiota affects:

  • Nutrition and growth.
  • Intestinal morphology.
  • Immunity.

Immunity is a hugely important factor when considering animal performance. An immune response is incredibly energetically expensive and detracts energy away from growth or egg production. Of a bird’s immune system, 70% operates through the gut. Ensuring that gut health and the microbiota are working effectively together is crucial to ensuring that immunity is fully functional.

Many factors can influence the microbiota and, hence, the immune status of an animal, including:

  • Feed and nutrition.
  • The environment.
  • Medication.

Commonly, when abiotic or biotic stressors are allowed into the production system — or, for example, if antibiotics are used — the diversity of the microbiota is reduced, which then makes it easier for unfavorable or pathogenic organisms to proliferate and invade. Bacteria produce their own micro-environment, allowing for more of the same species to grow. They can then use quorum sensing in order to communicate with one another and begin their invasion. This is usually to the detriment of beneficial bacteria. When situations like this arise, pathogens like Salmonella and Campylobacter are common invasion species.

So, what does changing the gut microflora have to do with food safety? If we can create a more diverse, balanced microbiota, this shifts the balance of species in the gut, reducing the risk of pathogen colonization.

Recent genetic profiling work has highlighted a reduction in Campylobacter and Helicobacter genus groups, as well as the impact of microbiota modulation on Salmonella. It shows that the modulated microbiota significantly reduces the amount of Salmonella found in the caeca and the ovaries, which will directly reduce the chances of horizontal and vertical transmission. This is particularly important in the laying industry, especially with birds being taken past their vaccination protection frame.

How to change gut microflora

One means of controlling this is through the rehabilitation of the microflora after stress or challenge. This reverses any diversity losses and promotes immunity. Alltech recommends the use of Actigen® for normalizing microflora and promoting microbiome diversity. The gut is vital, not only for immunity but for general performance, as this is the site of nutrient digestion and absorption. The efficiency of this process will directly influence performance. As a result, Actigen:

  • Increases weight gain.
  • Improves feed efficiency.
  • Improves livability.

Recent research has looked at the impact of Actigen on the caecal microbiota, which directly influences the metabolome and increases the amount of short-chain fatty acids found in the caeca. A changing metabolome creates a better environment for beneficial bacteria to grow, which means that they can outcompete less favorable species. Eventually, this means that the microbiota changes in profile. Early life nutrition is key to influencing the mature microbiome through the impact on succession to climax colonies, although beginning rehabilitation at any age will have an impact. This impact will then start to influence the house microflora, which will then impact the next flock.

Poultry meat and egg consumption is on the rise and is projected to continue growing at over 2%. This growth is a lifeline for farmers. With this increase, it is crucial that we do not allow there to also be an increase in foodborne illness or a food scare, like the Salmonella scare in the U.K. in the 1980s. Events such as these, even if not based solely on facts, can be detrimental to industries. Ensuring our food standards and safety will help us maintain customer trust and allow us to continue driving growth in sales. To do this, we must look within our flocks and focus on maintaining microbiota diversity.

How to increase egg production with gut health

Submitted by aledford on Mon, 04/27/2020 - 15:03

The egg industry is currently going through its fair share of challenges. With production outstripping consumption and prices being squeezed, producers are looking for more ways to improve the efficiency of their businesses.

To try to achieve this, many are looking into how they can:

  • Improve eggshell quality.
  • Increase the number of eggs laid, with regular discussions around a target of 500 eggs per bird.
  • Lengthen the laying cycle.

With these objectives in mind, the role of layer gut health in production has never been more pertinent.

Egg production, for the laying hen, is a taxing process, considering the energy they use and the stress they endure. It is a biologically complex procedure, and to achieve the highest-quality eggs, the bird’s performance needs to be optimal. By trying to push the boundaries of a bird’s laying capability, we run the risk of compromising the quality of the end result.

If gut health in layers is not at its best, you will see the effects in the eggs they produce. In fact, gastrointestinal challenges are known to be connected to:

  • Fragile shells.
  • Dirty eggs.
  • Short and less abundant laying cycles.

These are issues that will not only hurt your birds but, in the long term, hurt your profits, too.

By making gut health a priority, we can ensure that layers have the resources they need to produce successfully. On top of this, when we talk about pushing the boundaries in terms of what our birds can do, optimal gut health is the key to safely achieving these goals.

Eggshell essentials

When aiming to “improve eggshell quality,” it is essential to distinguish precisely what that means. Generally, a good-quality shell is one that does not crack easily and, as a result, will reduce the number of seconds. However, increasing shell thickness does not necessarily improve quality; it is the structure of the shell that is crucial.

Many enzymes and minerals are involved in the creation of the shell structure. Layers receive the required minerals through their diet, but these minerals must be readily bioavailable for them to be useful in the egg-creation process. The small intestine cannot absorb non-bioavailable minerals.

We also need to be wary of how much of a mineral is included in the diet formulation, as well as the interactions of that mineral once it is consumed. Calcium carbonate, for example, is crucial for eggshell formation, and it is often presumed that increasing the amount of calcium in the diet will automatically lead to more durable shells. However, there is a negligible balance to be considered. Calcium, when dissolved in the gastrointestinal system, can interact with other minerals, reducing their absorption. This, in turn, can have a direct impact on other structural components of the egg, diminishing quality.

With these factors in mind, the best method for ensuring optimum bioavailability is to use chelated minerals in the diet. They will have fewer reactions with other minerals, allowing the bird to absorb more of the mineral. By ensuring that layers are getting the most out of their feed, we give them the best chance to maintain a healthy gut and, as a result, produce high-quality eggs.

Laying healthier and longer

The laying hen can naturally continue to produce eggs for many years, but her peak production will naturally decline with age. Genetic advances in recent years have allowed birds to produce nearly one egg per day, from week 18 to week 75. In some cases, however, the push for large eggs — which come at end-of-lay — has extended this period to 80+ weeks.

Lengthening the egg-laying period puts more stress on the bird, as she must create a metabolically rich egg while also maintaining her body weight and dealing with any additional challenges from the environment that may impact the immune system. It is worth noting that if the energy requirements of the bird are not being met, at a certain point, her body will shut down the reproductive system that was producing the eggs in favor of supporting her body weight and providing energy for vital bodily systems.

Healthy gut, healthy lay

Between 50–80% of the immune system functions in some way through the gut. Many factors can trigger the immune system, such as:

  • Mycotoxins.
  • New diets.
  • High levels of potentially pathogenic bacteria, known as dysbacteriosis.

The immune response in the gut generally takes the form of inflammation, which produces additional mucous layers. Added mucous creates an extra barrier for the minerals to pass through before being absorbed. This means that if an inflammatory response is underway, it is unlikely that the bird will receive its full mineral requirement, impacting eggshell structure and, therefore, strength and quality.

Maintaining and promoting gut health in flocks:

  • Increases villi height.
  • Reduces villi-crypt ratio.
  • Improves tight junctions between cells.

Villi with improved height will have an enhanced surface area and, therefore, can absorb more nutrients to sustain the hen for longer lay cycles. Improving tight junctions will prevent bacteria from becoming translocated into the bloodstream, which can lead to a multitude of problems — including, in the worst cases, diseases like colisepticemia.

The addition of Actigen®, a unique bioactive product derived from the Saccharomyces cervisiae yeast strain, in layer feed can help to optimize gut health. Actigen works to normalize and promote diverse gut bacteria. This helps with the maintenance of the bird’s gastrointestinal integrity and stability, which, in turn, supports its immune defense and gut health.

Getting the balance right

In a natural setting, the microbiome — the microbial population in the gut — is developed from the mother as the chick is raised in the nest. Our modern systems mean that this does not happen, so the creation and maintenance of the microbiome should be considered when determining management practices. Keeping the microbiome balanced will go a long way to improving layer gut health and egg production.

Many producers have been successful in improving gut health and the microbiome via the implementation of Alltech’s Seed, Feed, Weed program to manage the composition of the intestinal microbial community. This involves accelerating the evolution of the microbial community to a steady state and then maintaining the status quo. The Seed, Feed, Weed program achieves this by:

  • Seeding the gut with favorable organisms.
  • Feeding these favorable organisms.
  • Weeding out the unfavorable organisms.

By helping to maintain the microbiome balance, this program works to improve shell quality and enable a healthier, longer lay.

Producers in the egg industry are desperately seeking out ways to help their birds continue to lay more in the safest way possible. Quality food will help layers produce quality eggs — but this is only effective if the bird is able to absorb the beneficial nutrients that come from it in the first place. Improving the gut health of birds in lay will enable them to absorb a higher proportion of their feed. This will not only aid the overall wellbeing of the layer but will also give them the foundations to successfully and safely produce better eggs for a longer period of time.

How to improve efficiency on your fish farm

Submitted by aledford on Wed, 03/18/2020 - 08:32

Getting the right start on-farm is key to optimal fish performance throughout their lifecycle. Each species of fish or shrimp requires a nutritionally balanced aquaculture feed that is tailored for each specific stage in their development. Providing nutritional solutions for the particular needs of larvae — their most critical life stage — benefits the fish during their entire lifecycle. An ideal start begins with optimal nutrition that supports the healthy development of all organs. Not meeting these nutritional requirements can potentially lead to deficiencies and deformities, such as poor growth and increased mortality, and, ultimately, result in decreased producer profitability.

Advantages of using a high-quality, nutritionally balanced aquafeed:

  • Minimal nutritional deficiencies
  • Optimal development and foundation for future growth
  • High digestibility for optimal performance and water quality

Creating an optimal fish ecosystem

In fish farming environments, some variables can affect production, including temperature, oxygen, ammonia levels and water quality. Modern recirculating aquaculture systems (RAS) give greater control over these factors. The same can be said for aquafeed production; the quality of raw materials, nutritional formulations, transportation, performance, climate and feed mill operation can all impact the performance and productivity on-farm. Fish will perform best when an optimal environment is maintained; aquafeed and aquaculture supplements play a critical role in this.

Creating an optimal environment relies heavily on water quality. It is crucial for maximum growth, health and survival throughout the production cycle. Ingredient quality and nutrient availability aids digestion and nutrient absorption and utilization, resulting in healthier fish, but also lower feces production and less pollution in the systems and the environment. Getting the foundations right as early as possible helps fish reach their maximum potential.

Maintaining water quality

Maintaining water quality is largely connected with the quality of aquafeed. Any uneaten or undigested feed that is excreted into their environment is not only wasted but also causes unnecessary pollution and additional, unnecessary stress. For this reason, the feed must be highly palatable and suitable for the correct species and their developmental stage. Not meeting these needs from the start can have adverse effects on fish health.

Recent research completed at the Alltech Coppens Aqua Centre displayed the improvements in growth and performance when feeding two of Alltech Coppens’ starter feeds to rainbow trout (Oncorhynchus mykiss) during the hatchery phase. The results of this benchmark trial are shown in Figure 1.

Figure 1. Results of a starter feed benchmark trial performed in the Alltech Coppens Aqua Centre.

 

Supporting internal defense systems

A fish’s skin, gut and gills are the primary points of interaction with the external environmental factors that can impact on their health. Both internally and externally, these organs must be protected. Included in all Alltech Coppens feed is a premix known as Aquate®. Aquate has been specially formulated to meet the specific requirements of each aquatic species and life stage. It encourages healthier and more robust populations and boosts natural defense systems, aiding gut function. The best farm results are seen when feeds containing the Aquate package are fed throughout the entire life of the fish, as this feeding strategy creates continuity in the supply of their nutritional requirements.

Advantages of sustainable aquaculture

We live in a rapidly changing environment, with pressure on nature, wild fish stocks and food security. This should not be underestimated; we have an obligation to produce sustainable, well-balanced animal protein responsibly. This is a commitment that we take very seriously in Alltech.

A key element in producing sustainable fish and seafood is the reduction of fishmeal and fish oil in feed production. When reducing these key ingredients, close attention must be paid to the nutritional balance of the feed to ensure it meets the essential nutrient and energy requirements of farmed species. The cost of aquafeed in aquaculture is the single highest operational cost for a producer in the industry. Any small change can have a significant impact on profit yield. It is necessary to look at the nutritional profile and quality of raw materials to find a balanced feed for each farm.

Innovative research in the Alltech Coppens Aqua Centre has led to lowering our carbon footprint, lowering phosphorus and nitrogen emissions and a low inclusion of fishmeal and fish oil in feed formulations with no impact on the growth and performance on-farm.
