Harvest samples from across the U.S. submitted to Alltech, an animal nutrition and health company, show high levels of mycotoxins. Corn grain samples averaged seven mycotoxins per sample, 3.9 more than the same period in 2017. Mycotoxins in corn silage samples were 6.8 per sample, compared to 4.6 during the same time period last year. Alltech’s Alexandra Weaver says this year’s extreme weather led to the increase. Mycotoxins can potential impact feed quality, as well as animal health and performance.
