This document discusses the roles of toxin binders, acidifiers, and mold inhibitors in animal feed formulation. It describes the types and effects of various mycotoxins on large animals and poultry. It then explains how toxin binders work to prevent mycotoxins from entering the bloodstream by trapping them. The main types of toxin binders discussed are silicate products, inorganic polymers, organic polymers, and carbon products. It also discusses the roles of acidifiers in inhibiting mold and harmful bacteria while improving beneficial bacteria. Finally, it covers the roles of mold inhibitors in minimizing and preventing mold growth and contamination in feed.
