The influence of enzyme preparations on the nutritional value of cereals for poultry. A review

Abstract

Supplementation of cereal based diets for poultry with enzyme preparations may notably improve the performance, and reduce the viscosity of digesta and excreta. However, the overall effect depends on the content of anti-nutritive non-starch polysaccharides (NSP) in diet and the age of birds. The paper presents the content of anti-nutritive NSP in barley, wheat, triticale and rye, and discusses their effect on digestion processes in birds of different ages and benefits due to exogenous enzymes supplementation.
