Grains can develop molds that produce my-cotoxin compounds either prior to harvest or while in storage. High-moisture conditions enhance the development of mycotoxin production. Vomitoxin (DON) appears to be the main problem, whereas in the tri-state area, aflatoxin is not a major problem. Mold inhibitors can be added to feeds to avoid the development of mycotoxin production. Certain mycotoxins can be partially detoxified by a variety of procedures, including ammoniation and heat treatment. Decontamination methods for grains in commercial use are regulated and require government approval. Hydrated sodium calcium aluminosilicate and bentonite have also been used and often result in improved animal performance. These products reportedly bind aflatoxin in the feed or intestinal tract, therefore decreasing their absorption from the digestive tract. These products, however, do not effectively bind all mycotoxins.
