The inclusion level of wheat in poultry feeds is limited by nonstarch polysaccharides (NSP). Feeding NSP will increase the intestinal viscosity and residence time of the digesta, reduce nutrient digestion, and absorption of nutrients by birds, thereby damaging the intestinal function and growth performance. The degradation of NSP in feed by supplementing NSP enzymes has a positive effect on nutrient availability and growth performance. Therefore, there is a need for a quick and reliable method to assess the efficacy of NSP enzymes from different types, sources, and processing techniques. Compared with the expensive and time-consuming in vivo method for animal feeding experiments, in vitro digestion has been proved to be a rapid method for predicting the efficacy of exogenous enzymes in various parts of the avian digestive tract. Therefore, in this study, the efficacy of different NSP enzyme sources on wheat ingredients and wheat basal diets were evaluated in vitro by simulating the avian digestive tract.
