CANADA - Remarks by Duarte Diaz, The University of Arizona, USA, during the ruminants breakout session at the 2016 World Nutrition Forum in Vancouver, Canada.

Summary

Mold growth is an inevitable consequence of feed production, as a result their harmful metabolites “The Mycotoxins” are commonly found in livestock diets. In the last 40 years great advances in the field of mycotoxins have increased our knowledge on the detrimental effects of these toxins on animal production. Climate change and agronomic practices play an important role in the unpredictability of mycotoxin contamination of feedstuffs. The primary classes of mycotoxins are aflatoxins, zearalenone (ZEA), trichothecenes, fumonisins, ochratoxins (OTA) and the ergot alkaloids. Due to the high variety of feedstuff utilized in dairy operations and the high production stress typically associated with modern dairying, mycotoxins are important anti-nutritional factors in dairy nutrition programs. In order to maximize dairy performance and health, mycotoxins analysis and mycotoxins prevention strategies must be part of all the dairy nutritional and health programs.
