摘要

The goal of prebiotic applications from different sources is to improve the gut ecosystem where the host and microbiota can benefit from prebiotics.It has already been recognized that prebiotics have potential roles in the gut ecosystem because gut microbiota ferment complex dietary macronutrients and carry out a broad range of functions in the host body,such as the production of nutrients and vitamins,protection against pathogens,and maintenance of immune system balance.The gut ecosystem is very crucial and can be affected by numerous factors consisting of dietary constituents and commensal bacteria.This review focuses on recent scientific evidence,confirming a beneficial effect of prebiotics on animal health,particularly in terms of protection against pathogenic bacteria and increasing the number of beneficial bacteria that may improve epithelial cell barrier functions.It has also been reviewed that modification of the gut ecosystem through the utilization of prebiotics significantly affects the intestinal health of ani-mals.However,the identification and characterization of novel potential prebiotics remain a topical issue and elucidation of the metagenomics relationship between gut microbiota alteration and prebiotic substances is necessary for future prebiotic studies.
