Research progress on regulation of feed enzyme preparation in chicken intestinal health
Poultry gastrointestinal tract is an important system for transforming ingested feed into nutrients needed for maintaining growth and reproduction.Chicken gastrointestinal tract is colonized with a large number of microflora,which play an important role in the health and function of the host.Feed enzyme preparation is a kind of protein with biocatalytic ability,which has the advantages of high efficiency,safety,non-toxicity,no residue,and green.It can adjust the physical and chemical properties of feed,affect the intestinal tissue structure,regulate the endogenous enzyme activity and intestinal flora,and thus improve the intestinal health and production performance of poultry.In this paper,the composition and function of gastrointestinal tract,the distribution of intestinal microorganisms and the regulatory effects of enzyme preparations on intestinal health in chickens were reviewed,in order to provide a reference for further research on the regulation of intestinal health by enzyme preparations.
