In this episode of The Dairy Nutrition Blackbelt Podcast, Dr. Duarte Diaz from the University of Arizona tackles the complex issue of mycotoxins in dairy feeds. He explores how mycotoxin contamination levels vary by region, season, and climate and how different feedstuffs, besides corn silage, are at high risk. Dr. Diaz also shared insights on testing frequency for mycotoxins and strategies for preventing contamination and growth in stored feed. Additionally, he discusses the role of feed additives and binders in mitigating the harmful effects of mycotoxins. Listen now on all major platforms!

"Mycotoxins interact with the plant, soil, and environment. Depending on the mold, climate, and competition, certain species dominate in different regions."
