Four major aflatoxins (AFB1, AFB2, AFG1 and AFG2) are direct contaminants of grains and finished feeds. Factors that increase the production of aflatoxins in feeds include environmental temperatures above 270C, humidity level greater than 62%, and moisture levels in the feeds above 14% (Magan and Lacey, 1988; Whitlow and Hagler Jr., 2002). The extent of contamination will vary with geographical...
