The hidden threat of fumonisin in cattle feed

Submitted by aeadmin on Tue, 10/31/2017 - 00:00

Fumonisin is commonly found in corn at levels of 2 parts per million (ppm) or less, but in recent years, testing has confirmed levels well above 30 ppm, and some even above 100 ppm. Livestock producers should be aware of the fumonisin contamination when purchasing grain because, when consumed by animals, fumonisin toxicity affects several of their biological systems, leading to reduced feed intake and efficiency and liver damage. Understanding the effects of these mycotoxins in cattle feed is key to maintaining animal health and productivity.

Mycotoxins in contaminated feeds have differing effects on animals. 

Mycotoxins are secondary metabolites of molds and fungi that infect plants. More than 500 mycotoxins have been identified, and most animal feedstuffs are likely to be contaminated with multiple mycotoxins. The effects of mycotoxins vary, as each mycotoxin has its own specific impact on the animals consuming the contaminated feeds.

The Fusarium species are the predominant types of mold that contaminate crops and, eventually, animal feed. Ranging from white to pink or red in color, these molds are associated with wet conditions and moderate temperatures, especially following insect or hail damage. They are found worldwide, largely in corn. Fusarium molds produce several mycotoxins, including fumonisin, deoxynivalenol (vomitoxin) and zearalenone, with higher concentrations in the stalks and cobs than in the grain.

Signs of fumonisin in cattle

While cattle are generally resistant to many of the negative effects of mycotoxins, thanks to the degradation of the compounds by rumen microbes, high levels of mycotoxins in feeds can significantly impact animals. Fumonisin, in addition to not being significantly degraded in the rumen, is also not well-absorbed. The majority of fumonisins consumed by cattle are passed out in the feces. However, fumonisins can overwhelm the gut and cause significant issues in cattle.

The presence of fumonisin in the feed reduces palatability and, as a result, slows intake. Cattle may stand off a bunk contaminated with high levels of fumonisin. Calves without fully developed rumens and animals that are dealing with stressful situations, such as weaning or transportation, have an increased sensitivity to fumonisin due to reduced rumen fermentation and weakened immune functions.

Fumonisin can negatively impact animal health:

Even low levels of fumonisin affect gut health.

The gastrointestinal tract is impaired when cattle consume mycotoxins. Gut epithelial cells need protection from direct interaction with microbes and the gut environment. Specialized cells in the epithelium provide this protection. One example of these specialized cells is goblet cells, which produce mucus, coating the epithelial cells to lubricate and protect them from the contents of the gut. Intestinal cells also have specialized structures to form tight junctions, limiting the passage of molecules between cells. These mechanisms and others work in concert to prevent pathogen colonization and systemic access by toxins and pathogens.

Although fumonisin is poorly absorbed and metabolized by cattle, it induces disturbances in the gastrointestinal tract. Rumen motility can slow down, resulting in the increased exposure of the intestinal epithelium to the effects of fumonisin and other mycotoxins. Even low amounts of mycotoxins in cattle feed can impair intestinal health and immune function, resulting in altered host-pathogen interactions and an increased susceptibility to disease. The epithelial cells in the gastrointestinal tract are damaged by fumonisins, reducing the mucin layer thickness, tight junction strength and cell proliferation and, ultimately, increasing the opportunity for pathogen invasion.

Fumonisin has toxic effects on the liver and kidneys.

An analysis of tissues from cattle fed Fusarium in high doses indicated that the majority of fumonisin absorbed is retained in the liver, with lesser amounts retained in the muscles and kidneys. This accumulation is concerning, as fumonisin is toxic to the liver and kidneys and causes apoptosis, followed by the proliferation of regenerative cells in the affected tissues. Fumonisin also reduces the antioxidant levels in the liver, decreasing the animal’s defense mechanisms. This leads to liver lesions and elevated enzymes that are indicative of liver damage.

Fumonisins interrupt sphingolipid synthesis and metabolism.

The disruption of sphingolipid metabolism is the mechanism underlying much of fumonisin’s negative impact in the body. Sphingolipids are specific types of fats that protect cells from environmental damage by forming a stable, chemically resistant layer on the cell membrane. Fumonisins disrupt cell signaling by inhibiting ceramide synthase, interrupting sphingolipid synthesis and metabolism, and can alter the morphology of affected cells. This reduces cellular stability and protection, leading to cell death and significant alterations to cellular metabolism and cell-to-cell communication. 

Mycotoxins can increase susceptibility to diseases.

Calves that consume fumonisin experience decreased immune function, due in part to the impairment of lymphocyte development. Sphingolipid metabolism in immune cells is involved in the signaling pathways that control lymphocyte development, differentiation, activation and proliferation. Lymphocytes are the white blood cells that are important for maintaining a strong antigen response. These lymphocyte-related problems mean that consuming Fusarium molds can increase an animal’s susceptibility to diseases and reduce vaccine efficacy.

Handling contaminated feed in your beef cattle operation

Unfortunately, once mycotoxins are formed in the plant, there is no commercial method of removing them from contaminated feeds. Harvesting and storing contaminated crops at low moisture levels (i.e., less than 15%), along with the separation of highly contaminated feeds, is important in order to reduce the risk of mold growth and mycotoxin production in uncontaminated grain.

While the European Commission recommends that adult cattle can tolerate fumonisin levels of up to 50 ppm in diets, the U.S. Food and Drug Administration’s guidance for fumonisins recommends a maximum concentration of 30 ppm in the diet of feedlot cattle, 15 ppm for breeding stock and 10 ppm for calves. Furthermore, contaminated corn or corn byproducts should contribute no more than 50% of the diet. It is crucial to check the level of fumonisin in the complete diet, as it can be three times more concentrated in corn byproducts, such as distillers grains and corn gluten feed, and 10 times more concentrated in corn screenings.

If contaminated feeds must be used to feed cattle, elevators may blend the corn to reduce the fumonisin concentration to acceptable levels, or producers can include feed additives to mitigate the risk of mycotoxins. As fumonisin is associated with reduced feed consumption, there is a concern that low levels of fumonisin can interact with other mycotoxins, reducing the growth of calves and slowing the weight gain of feedlot cattle. Fumonisin contamination can be especially detrimental to newly received cattle and calves, preventing them from getting off to a healthy start.

Testing services like Alltech® 37+ and Alltech® RAPIREAD® can help producers and feed mills assess their mycotoxin risk so that the appropriate management and nutritional measures can be put in place.

Pig-ease: Using environmental control to help pigs adapt and grow

Submitted by aeadmin on Mon, 10/30/2017 - 00:00

Environmental control in pig housing is important for animal growth and health. Modern farms have computer-controlled systems that are adjusted automatically to optimize the environment depending on the stage of growth or reproduction, based on ideal temperature curves established from research and models. For example, for growing pigs, temperature needs to decrease by set amounts as they increase in body weight. However, it is important to ensure the correct growth curve is selected in any automated system to account for breed, age and health of the animals.

When animals have been moved to new housing, perhaps following weaning, it may take several days for them to adjust to their surroundings and the new supply of water and feed, and feed intake may drop during this time. The environmental temperature will need to be held at a higher level, compared to their weaning shed, until they have adapted suitably and resumed consumption and growth. Therefore, although computer-controlled systems are very useful, management by personnel and suitable reactions regarding changes in the regulation of temperature are still key to ensuring the growth and health of the pigs.

Relative humidity

Relative humidity (RH) is defined as the ratio of air-water vapor at a specific temperature compared to the maximum amount of water vapour the air could hold, expressed as a percentage. Under normal, ambient temperatures, pigs can tolerate wide ranges of RH, although RH is still used to assess air quality in housing, and RH should be maintained between 60 percent and 90 percent. Nasal mucosa can be severely reduced in very dry housing conditions (low RH), leading to an increased risk of developing health problems from airborne pathogens, particularly those of the respiratory tract. Conversely, in wet conditions with higher RH, pathogens present in water droplets increase exposure to disease.

For nursery pigs, high RH can be a problem when the ambient air temperature is low, as automated ventilation systems reduce the amount of fresh air circulating within the house, allowing RH to increase to problematic levels. Under these conditions, an increase in respiratory disease can occur, which may affect the health and growth of the pigs. Intervention by management personnel is required under these conditions to ensure ventilation rates are maintained. Additional space heaters can be used to get the house up to temperature before moving the piglets.

In modern housing systems, both temperature and RH can be controlled automatically via sensors. However, care is needed with these, as they can become damaged during clean out and power washing. Their accuracy should be verified on a regular basis using handheld and empirical devices.

Feeding Fido: Functional pet food ingredients

Submitted by aeadmin on Sun, 10/29/2017 - 00:00

Today’s high-quality pet foods include a number of functional ingredients to improve the overall health of our beloved pets. Some of these ingredients claim improved digestive health and better stool quality, which is especially important to on-the-go urban pet parents living in small spaces — less mess to pick up.

Today’s pet food choices are quite extensive, from specific breeds, sizes, life stages and activity levels to allergies and sensitivities. The choice overload can make the purchasing decision an intimidating task for some pet parents, especially for first-timers.

How can we make choosing what to feed Fido easier? Let’s take a closer look at functional ingredients and why you might want to consider finding a food that contains them.

Functional ingredients in pet nutrition

Functional ingredients are ingredients that provide health benefits beyond basic nutrition, such as prebiotic fibers, beneficial probiotic bacteria, omega-3 fatty acids (DHA/EPA) and enriched selenium yeast.

Why should I look for functional ingredients in a pet food label?

Functional ingredients can provide health benefits when part of a complete and balanced diet. Prebiotics and probiotics have been reported to positively influence and maintain normal digestive health.

The food you choose could cut time poop scooping

The amount of pet waste correlates to the amount of indigestible content in the food. A healthy stool is moist and firm and has a mild smell. Prebiotics and probiotics in your pet’s food would help maintain normal digestion, minimizing issues that could create messy and smelly stools.

What is that smell?

Your pet’s waste is just residues from digestion. Bacteria decomposition and ammonia production occurs inside the intestine and then is released with the feces. Smell can be a challenge, particularly in confined spaces with poor ventilation.

Yucca schidigera: The secret of the desert

Yucca schidigera is a plant that grows in the southwestern deserts of the United States and Mexico. It has mainly been used for ammonia and odor control in livestock production, but it has application in pet foods that have high meat content because of its efficacy in helping metabolize protein and nitrogen.

How do I know if my pet food contains functional ingredients?

Ingredients are listed by the name required by the regulatory authorities. Here is an example of how some functional ingredients may be listed on the label:

  • Beneficial probiotic bacteria (e.g.,Lactobacillus strains)
  • Omega-3 fatty acids (DHA/EPA): Marine sources are best, such as fish oil and algae.

Aman Sayed: The emergence of India

Submitted by aeadmin on Fri, 10/27/2017 - 00:00

The following is an edited transcript of Luther Andal's interview with Dr. Aman Sayed, managing director of Alltech India and regional director of Alltech South Asia.

Click below to hear the full interview:

Luther: Dr. Aman Sayed is managing director of Alltech India and the company’s regional director for South Asia. Welcome.

Aman: Thank you.

Luther: Give us an overview of India as a country, as a culture and as a people.

Aman: Well, let me start with saying that India is going through a big transformation at this point in time. What is there in India, and why should the world look at India today? The biggest strategic asset that India has is the population today. After independence, for a few decades, people were considered a liability or burden. However, now, people are considered an asset and human capital. There are about 1.33 billion people in India. Over the next five to six years, we will be the most populated country in the world.

Looking at the demographics of the population, we are a young India today. The median age is 28, which is much lower compared to the rest of the world. This poses a great opportunity, I believe, to the rest of the world and is why they need to look at India. In a very short period, I would say that India will become a sought-after country for business because there is a readily available workforce of talented, educated people.

Luther: India is very diverse as a culture and in terms of language, and religion, and states — union territories. Can you just give us a little overview of that diversity?

Aman: We have about 29 states in India and seven union territories. There are 22 official languages, but there are more than 1,000 dialects and more than seven religions. But we live together in great harmony. It’s important to understand that every state, in a way, acts like a different country. So, understanding the Indian culture for an outsider is quite important.

We live together all in harmony, despite being of different religions and different languages. But, again, the country brings everybody together. Though the national language is Hindu, most of the people speak English, which is another great asset for us. I have no doubt in a decade, India will be the number one English-speaking country in the world.

Luther: Right now, they’re number two.

Aman: They are. Yeah.

Luther: Tell us a little bit about the Indian economy. How fast is it growing? Maybe give us the breakdown of gross domestic product (GDP) at a high level.

Aman: Since gaining independence, we have grown at a rate of about 3 and 3.5 percent for about 40 to 50 years. But since a transformation in 2002, we have started growing at 78 percent, and we are now the fastest-growing country in the world in terms of economy. As far as the GDP, we are about $8.7 trillion today — third in the world. So, we have a significant contribution from the services sector, followed by the agriculture and the industrial sectors. We have surpassed China in GDP growth. And that’s one of the reasons why the world is looking at us today.

Luther: One of the fascinating things that you brought up was the new way that India looks at its people as a resource and as capital. That’s a big transformation, and it’s been part of the growth of the economy. Correct?

Aman: That’s right. And people are educated now. People are talented and they are readily available for the rest of the world. I believe that with the changes to immigration laws across the world, it will be time for the other countries to operate within India and export products, rather than the Indian workforce.

The number of talented people keeps growing, and the rest of the world will have to confront the fact that, in the future, their top management team is likely to come from India. The growth is coming from India — a generation in India — and they are really talented.

Luther: So, in terms of that resource capital, since around 2002, as you said, a lot of that has been some outsourcing IT, but you’re talking also about the development inside of India — of companies, startups and other areas. Correct?

Aman: That’s right. India is the number three country in the world in terms of startups. There are more than 4,200 startup companies in India. And they are all looking for help. And that’s something that the rest of the world needs to look at and consider investing in and trying to help. We know that more than 90 percent of startup companies fail — but why not look at those remaining 10 percent in terms of how we could assist in bringing their innovation and disruption to the world?

Luther: When we talk about the Indian economy — we’ve talked about trends toward education, toward technology — and diversity is obviously a part of it. What about the trends toward urbanization in India?

Aman: Today in India, there are about 630,000 villages. Seventy percent of India is rural, and there is constant migration from the rural villages to larger cities in India. Two out of every five Indians are migrants. So, that brings a significant opportunity for those companies that are a part of the rural economy, as well as those who consider the cities. This migration will continue until 2050. Why is this migration there? There’s migration because of education; to get better work. This is going to continue for a few decades, and it’s something one should consider in terms of the opportunities and where the human capital is.

Luther: We’ve seen a lot of changes in India. What about food? Have there been changes in preferences or taste palate in India as these changes have occurred?

Aman: Well, as you know, they say that Indian food is probably the best-tasting food in the world. During the last fiscal year, we produced record food gains. But it would still be fair to say that we are a hungry India, even today. There are a lot of reforms required, whether they’re for the prevention of wastage, better processing technologies and so on. We have a big population that is anemic. We have a very big population that is underweight and undernourished. So, there is an opportunity for companies in the food sector to come to India and explore which part of the supply chain they could help and assist and at the same time do business.

Luther: Well, following up on that point of agriculture, what’s going on with agriculture in India today?

Aman: Well, let me start by saying that, for an agriculture farmer today, the land holding is quite low compared to other countries. Each farmer holds a plot size of about 1.2 hectares. So, that poses challenges. But having said that, the Indian farmer is going digital. That digitization has transformed — and continues to transform — the agriculture industry.

Today, we have a situation in which, because of smartphones — even though the farmer’s literacy rate is very low — they are able to use the smartphones effectively. They are able to buy seeds through WhatsApp, for example. They are able to see the market price for their produce, whereas previously they would have taken produce to market to be sold for the going rate that day. Now they know the market price beforehand.

So, the digitalization in agriculture is increasing and improving. There are primary banks that have now gone into rural India. Financial literacy is also improving for the farmers, which is great. Indian farmers were previously prey to money lenders, who charged 40 to 50 percent interest rates. Now that has changed. So, it’s a great opportunity, I think, for agri-finance companies that are into improving the yield or into processing. There are significant foreign direct investment benefits provided to foreign companies by the Indian government, particularly in the food retail side of things.

Luther: How important is the dairy industry to India?

Aman: India is the number one milk producer in the world. We have lots of cows — about 300 million. You may say the yield is low, but we are getting better. We are improving our genetics. We are improving our nutrition. It’s a great opportunity, even for countries outside India.

In another decade, we will need about 200 million metric tons of milk. Is that milk going to come from India? Probably not. We may have to import milk in India from other parts of the world. The only question is: Are the countries outside India willing to export milk to India in that situation? We are going to need a lot of milk. Coming back to your question on the dairy sector, there is about 4 percent total growth every year. The milk products are growing at a rate of 20 to 25 percent, whether it’s cheese, butter, ghee — all of those. So, it’s a big transformation happening in the dairy sector as well.

Luther: We’ve covered the fact that India has an educated workforce, that they have a lot of experience with technology, certifications that are necessary for outsourcing, but also the fact that they are growing startup-wise and have a lot to offer. What other advantages do they offer the world?

Aman: Well, I think the biggest advantage is the talent and the IT sector, which is growing at a rate of 14 percent. You see, there is a lot of high-information technology and the business process outsourcing (BPO) side of things, which is growing and significantly contributing to the Indian GDP. Indians have a 67 percent market share of IT revenue. So, in the “Silicon Valley of India” — which is Bangalore — you have a lot of IT. And, as I said earlier, with the changes in immigration laws, I think it is important for countries to go to India and hire those talented people, and work with them, and get the best out of it. So, I see that as a significant impact.

Luther: Can you give us a little history on Alltech in India?

Aman: You know, Dr. Pearse Lyons had the dream to go to India. It was in the late 1990s. And in 2001, when we set up Alltech India, we disrupted the technology and the traditional method of feeding trace minerals in India, whether it was within the poultry, dairy or aquaculture industries. Today, Alltech has 30 percent of the market share in terms of the minerals. On the dairy front, we have disrupted the traditional method of testing the feedstuff by introducing the Alltech® In Vitro Fermentation Model (IFM).

Now, the dairy producers look to Alltech India to help redefine the nutrition and provide better nutrition and improve the efficiency for the cows. Overall, it’s a profitable situation for the farmer. And now, after having registered Alltech Crop Science, we are looking at disrupting the fertilizer market as India moves toward organic farming. So, I think that’s what we contribute to the industry — what Alltech contributes to the industry — that’s quite significant.

Luther: The term “rising billions” has been widely discussed. It is the emergence of markets in India and people in India, China, Africa and other areas of Asia that are moving up and coming into a middle class, coming into a workforce, becoming urbanized. Can you just discuss with us, as Alltech does their work in India, how important it is for the future of India in terms of feeding the country themselves and in general meeting the demands of the future?

Aman: You pointed out, very rightly, the rising billions. In the first 50 years of independence, our economy grew at just about 3 percent. We had the spike of 5 percent once or twice, but it wasn’t stable. So, it took almost 45 years or so for India to double its per capita income. Now there is a 7 percent growth in the economy — which is likely to reach double digits, growth in population of about 1.5 percent, and every Indian will double their per capita income in about eight to nine years — in even less time — four to five years — in urban areas So, you are right. A billion people are growing through prosperity. The only question is for the rest of the world: Would you like to be a part of this prosperity?

India today is at a stage of fast forward. The question to the rest of the world is: Would you like to be a part of this journey? And Alltech India is strategically placed to work with those farmers. When you said, “the middle class,” more than 50 percent of Indians belong to this segment today. And many of them have the desire and the dream to prosper in their life through dairy farming, through fish farming, through aquaculture —fish farming and shrimp farming. So, we are rightly placed at Alltech India to work with those farmers and be a part of their prosperity.

Luther: So, what does the future hold for India? Can you summarize that? What do you see? Where are we going?

Aman: I have no doubt that in 2040, India will be a superpower. The only question for the rest of the world is: Would you like to be a part of this successful ship named India?

Luther: What do you enjoy most about your job?

Aman: I love to meet people. I love traveling. The most enjoyable part for me is interaction with my team, which is great. Let me also tell you, that is quite unusual in the marketplace. The attrition rate in India today is about 20 percent in most workforce segments, including IT. However, in Alltech India, you will be surprised to know that for the sales team, our attrition rate has been zero for the last 18 months — quite unusual.

Luther: Dr. Aman Sayed is managing director of Alltech India and the company’s regional director for South Asia. Thank you for joining me.

Aman: Thank you very much.

Alltech Young Scientist inspires confident research

Submitted by aeadmin on Thu, 10/26/2017 - 00:00

I was born in Chapeco City, Santa Catarina State, Brazil. I grew up in a small city, where my parents raised dairy cattle. That is when my interest in studying dairy cattle began. After I finished high school, I was sure that I wanted to study animal science, and I completed my bachelor’s degree in animal science at Santa Catarina State University. I received my master’s degree from the Luiz de Queiroz College of Agriculture at the University of São Paulo, where my research evaluated the effects of fatty acid supplementation on the performance and metabolism of dairy cows grazing tropical pastures. My doctoral dissertation at Michigan State University examines the effects of altering the dietary ratio of fatty acids on the energy partitioning of dairy cows under different physiological conditions.

My first study from my research in Michigan was the base for my application to the Alltech Young Scientist program. My research has focused on altering the fatty acid profile of dairy cow diets and how that impacts feed efficiency and energy metabolism in dairy cows. The results suggest that different fatty acids can alter energy partitioning between the mammary gland and adipose tissue, which may allow for the application of different fatty acids in different situations according to the metabolic priority and needs of dairy cows. This may provide key information on how to group cows to properly feed them to meet their requirements and maximize milk fat yield. There is tremendous potential for increased profitability and farm efficiency by improving milk fat yield through improved understanding of how fatty acids are metabolized and partitioned to different tissues.

Being selected as the global winner of the Alltech Young Scientist program was the biggest achievement of my career, especially since I competed with other brilliant scientists with very solid research. It has certainly given me more confidence in presenting my research. However, this prize was not only a personal achievement, but also the achievement of several other collaborators and mentors that I have had throughout my career.

I will complete my Ph.D. by next year, and I would like to continue working with research and training people. My overall research interests and expertise cross several boundaries, which enables the integration of several disciplines and will result in many opportunities to collaborate with researchers and others within the industry.

Dr. Mark Lyons

Dr. Mark Lyons grew up in the Alltech business, having traveled with his father and Alltech’s founder, Dr. Pearse Lyons, from a young age to visit customers. With experience working in all regions and nearly all departments — before even officially joining Alltech — he has a deep and uniquely personal knowledge of the company. Based on Alltech’s belief that agriculture has the greatest potential to positively shape our world’s future, he launched the Planet of Plenty™ vision in 2019. He has called for collaboration to provide nutrition for all, revitalize local economies and replenish the planet’s natural resources.

Dr. Lyons began his career at Alltech focused on the development of the company’s core nutritional technologies. He spearheaded many critical projects, including simultaneously managing the establishment of a plant in Serbia and the creation of Alltech’s flagship yeast production facility in São Pedro, Brazil. He also spent nearly four years in Mexico rebuilding the company’s solid state fermentation plant in Serdán, which is one of the largest of its kind in the world. 

Under his leadership as director of North America from 2009 to 2011, Alltech expanded its presence with the opening of new offices and a growing involvement in all agricultural sectors. In 2012, Dr. Lyons relocated to China, the world’s largest feed market, as part of Alltech’s focus on the Asia-Pacific region. Living in Beijing and traveling throughout the country, he led the Alltech China office and focused on building bridges between China and the wider industry through research, education and strategic initiatives.

Today, Dr. Lyons is based at Alltech’s headquarters in Kentucky, USA. He serves on the CLEAR Center Advisory Council and is active in many industry groups. Dr. Lyons has published papers and patents in areas ranging from enzyme production to global economics and is interested in the assurance of food safety and quality throughout the entire food chain. 

Dr. Lyons received his bachelor’s degree in political science and environmental science in 1999 from the University of Chicago. He received his master’s degree in brewing and distilling in 2001, followed by a Ph.D. in the area of solid state fermentation, at Heriot-Watt University in Edinburgh in 2008. Dr. Lyons is fluent in Spanish, Portuguese, French and German, and he has a working knowledge of Mandarin.
