Abstract

Abstract: Gut microbiota plays an important role in regulating host physiology,metabolism and immune function,and is one of the important factors affecting pig health and economic traits.In recent years,the researches and understanding of porcine gut microbiota have become more and more in-depth.Understanding the composition of porcine gut microbiota can provide the references for improving pig health and production performance from the perspective of gut microbiota.The author firstly reviewed the composition of gut core bacteria in different developmental stages and gut locations of commercial and Chinese indigenous pig breeds.Then,the effects of host genetic background,diets,sex,environment,and the use of antibiotics,probiotics and feed additives on the gut microbial composition were systematically summarized.Finally,the main roles of porcine gut microbiota on feed efficiency,fat deposition,host behavior and immune inflammation response were summarized.

Key words: pigs; gut microbiota; core bacteria; function; influencing factors
