Alltech 2015 Harvest Analysis confirms swine and poultry feed at risk for mycotoxins

A wet spring and a late dry season took its toll on the 2015 North America crop, producing irregularities in plant growth and now putting poultry and swine at risk for mycotoxin exposure, according to Alltech’s North America Harvest Analysis.
The annual study surveyed 100 North American corn samples from across the United States and Canada from September to November 2015, testing for mycotoxin contamination to determine the risk posed to monogastrics. The Alltech 37+® mycotoxin analysis found an average 3.1 mycotoxins per sample that ranged from lower to higher risk for both swine and poultry. Ninety-seven percent of samples tested positive for at least one mycotoxin.
The harvest analysis revealed the greatest prevalence of Fumonisins, Fusaric Acid and Type B Trichothecenes in both the Midwest and East Coast regions. Type B Trichothecenes and Fusaric Acid can interact synergistically with each other, increasing toxicity and elevating the potential to impact livestock and poultry health and performance.
Ingestion of Fumonisins can cause reduced feed intake, damage internal organs such as the liver and lungs, suppress the immune system, increase the number of gut pathogens and susceptibility to disease and cause poor vaccination response.
A similar analysis of 53 wheat crop samples from across the U.S. and Canada showed an average 2.9 mycotoxins per sample, with Type B Trichothecenes and Fumonisins as the most predominant. Due to the levels present, nursery pigs and growers/finishers are at high risk and poultry layers and broilers at moderate risk for performance impacts.
“Management practices to prevent exposure are always the best course of action,” said Dr. Alexandra Weaver, Alltech Mycotoxin Management technical specialist. “Producers should consider testing feed samples to understand levels prior to storage and to understand the possible synergistic effects multiple mycotoxins can play in animal health and performance.”
According to Weaver, scientific literature shows that on average, the risk levels (moderate) from this year’s corn crop may cause nursery pigs a reduction of 6.8 grams per day in average daily gain and an increase of 0.5 percent feed conversion rate (FCR). With this loss in performance and considering current prices, the reduction in net return per nursery pig is an estimated decrease of $6.23 margin over feed per pig. Grow finish pigs could see a reduction in average dairy gain by 24 grams per day with an increase in FCR by 14 percent. With this loss in performance, total carcass profit could see a decrease of $3.09 per pig.
At an average risk level (low) from corn, broilers may exhibit a reduction in .2 pounds in carcass weight per bird. Additionally, FCR may increase by approximately 4.7 percent causing an extra 2.5 days to reach desired market weight. With this loss in performance and considering current prices, the reduction in net return for broilers is an estimated decrease of $0.21 per bird.
“Even at low levels, mycotoxins may impact animal health and performance, resulting in a negative impact on profitability,” Weaver said. “Mycotoxin management from field to feedout is critical for reducing risks.”
Dr. Alexandra Weaver, Alltech Mycotoxin Management technical specialist, reported the latest crop results from corn grain tested through the Alltech 37+® mycotoxin analysis during the company’s annual North America Harvest Analysis webinar for monogastrics.

Well , though its correct that dealing with mycotoxins is much difficult talsk, but keeping Cereals in sunlight for 24-48 hrs, can decrease the dose of mycotoxins. As ultravoilet rays in sunlight inactivate the certain mycotoxins. So this practice should also be used alongwith the upmentioned regimes to combat mycotoxins.

it is very difficult to manage properly mycotoxins. there are not much products that can mitigate or reduce the amount of ppm's in an infected wheat or barley. In my experience, I have implemented the following methods: 1. if you have a good bin storage capacity, separate the ingredients by level of mycotoxins and use it accordingly. mix low levels of micotoxin grains with high levels to achieve a level in which the animals are not susceptible. 2. according with the level of micotoxins in the sample, create a program to received just feed within the levels of your program and reject all other grain that can increase your levels. both options need a mycotoxin detection program. eventually, we need to find a way to mitigate micotoxins in our grains. the report is conclusive in say, be careful, you are dealing with at least 3 mycotoxins in your feeds.

What type toxin are risk at swine and poultry and which raw materials are unsafe for use swine and poultry feed!

Sun drying is not practical at feed millers level. Once the The damage has started or commodity is at risk then mixing of grains after lab testing n use of mold inhibitors n toxin binders seems the practical options. Dr yaser. MPhil A.N

Thank you!

So what do we do to mitigate the threat? Do we change the kind of feed we use? Or is there a medication or probiotic we can use?
