Abstract

Abstract:

Intestinal flora is an important part of the host defense mechanism, and plays a crucial role in animal health and its host defense against pathogenic microbial infections, and an imbalance of intestinal flora can lead to a variety of intestinal diseases. Fecal microbiota transplantation (FMT) is one of the most effective methods to regulate intestinal microbiota and treat intestinal diseases. Intestinal dysfunction caused by intestinal microbiota imbalance can be improved by FMT. In this paper, the potential mechanism of FMT in improving intestinal barrier function and the development prospect of FMT from the perspective of intestinal microbial barrier, chemical barrier, physical barrier and immune barrier of piglets were reviewed, in order to provide reference for promoting the application of FMT specification in pig production.

Key words: fecal microbiota transplantation, weaned pigs, intestinal microbiota, intestinal barrier
