Naturally occurring toxicants in feeds in animal nutrition and their deactivation methods
Naturally occurring toxins in plants are the nature ' s defensive agents for the plants and produce deleterious effects in livestock , and known as Antinutritional factors (ANFs) . Certain enzymes are also used to supplement the naturally occurring enzymes (e.g . lipase). A description of ANFs and methods to eliminate / minimize these in certain feed ingredients are given. In poultry nutrition, the feed ingredients are also supplemented with feed supplements such as toxin binders, antioxidants. Emulsifiers, vitamins, trace minerals etc. SOYBEAN (Glycine max) MEAL In animal nutrition Soybean meal (SBM) is the principle protein source for monogastrics.
