This document discusses various mycotoxins found in grains and feed ingredients. Mycotoxins are toxic fungal metabolites that can cause illness or death in livestock if consumed. The document outlines specific mycotoxins like aflatoxins, deoxynivalenol, zearalenone, ochratoxin A, and fumonisins. It describes the fungi that produce each mycotoxin, as well as the clinical signs they can cause in animals like pigs, poultry, and horses. Maintaining proper moisture and temperature conditions is important to prevent the growth of mold and mycotoxin production in stored grains and feed.
