摘要
猪体内脂肪沉积受遗传、饲粮、饲养管理和肠道微生物等多种因素的影响。脂肪沉积性状是重要的经济性状,过多的脂肪沉积影响胴体品质和饲料利用率。越来越多的研究表明,肠道微生物在宿主脂肪沉积中起重要作用。本文概述了猪肠道微生物的组成情况,在此基础上系统综述了已鉴别的影响猪脂肪沉积的肠道微生物种类,归纳了肠道菌群影响宿主脂肪沉积的可能机理,并根据国内外研究进展,总结了通过调控肠道微生物组成改善宿主脂肪沉积的方法,并展望将来的研究方向,旨在为将来通过调控肠道微生物来减少猪体内脂肪沉积、提高瘦肉率等提供参考。
Fat deposition in pigs is influenced by many factors such as genetics,diet,feeding management and gut microbiota.Fat deposition is an important economic trait,and excessive fat deposition affects carcass quality and feed utilization.More and more studies have shown that gut microbiota plays an important role in host fat deposition.In this paper,the composition of pig gut microbiota community was first summarized.And then,the gut microbial taxa that have been identified so far to affect the fat deposition in pigs were systematically summarized.The possible mechanism of the gut microbiota affecting host fat deposition was also reviewed.According to the current research progress all over the world,this paper induced the progress on the methods to improve host fat deposition by regulating the gut microbial composition,and briefly looked ahead the possible research direction in this area in the future.This review provides a reference for reducing fat deposition and increasing lean meat percentage in pigs by regulating gut microbiota in the future.
