A Mini Review of the Effects of NSP and Exogenous Enzymes in Broiler Diets on Digestibility and Some Intestinal Functions

NSP (non-starch polysaccharides) are a large group of compounds, which vary greatly in their chemical structure and properties. They are linked with the use of some of the alternative proteins or energy feed ingredients in broiler nutrition. Exogenous enzymes which act on NSP are sometimes in broiler production with the purpose of increasing digestibility of nutrients and consequently increasing broiler performance in production. This paper will attempt to review changes occurring in the digestive tract as a result of the use of feed with NSP soluble and insoluble in water, and the effect of NSPase on them, in terms of how an animal organism is burdened or helped to overcome the problems.
