Aflatoxins are produced by several species of the Aspergillus mold. They may occur at specific temperatures, moisture levels, and nutrient availability conditions both before and after crops are harvested. Contamination of grains with aflatoxins is usually particularly high during warm, humid weather conditions or after a drought, as well as in sub-tropical regions.
Ruminant diets include cereals, protein feeds, their by-products as well as hay and grass, grass/legume, whole-crop maize, small grain or sorghum silages. Furthermore, ruminants are annually or seasonally fed with grazed forage in many parts of the World. All these forages could be contaminated by several exometabolites of mycotoxigenic fungi that increase and diversify the risk of mycotoxin exposure in ruminants compared to swine and poultry that have less varied diets. Evidence suggests the greatest exposure for ruminants to some regulated mycotoxins ...
