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

Abstract

Summary 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.

“…In addition, exogenous enzymes have an indirect effect on the composition of the microbiota, which may be influenced by the short-chain oligosaccharides that are released from the NSP. These oligosaccharides have the ability to have prebiotic effects and have varying effects on performance ( Gadde et al, 2017 ; Polovinski-Horvatović, 2021 ).…”

“…The market for organic poultry products was estimated to be $350 million in 2008 ( USDA-ERS, 2014 ). Despite having 9 million certified broilers, 5.5 million certified layer hens, and 400,000 certified organic turkeys, the industry has been unable to meet increased demand for organic poultry ( USDA-ERS, 2014 ; Gadde et al, 2017 ; Polovinski-Horvatovi, 2021 ). This indicates the great potential for the organic poultry business to grow, as predicted by the organic trade association.…”
