摘　　要：酵母细胞壁多糖又称酵母多糖,作为一种安全、高效的生物活性饲料添加剂,具有多种生物学功能,如增强动物机体免疫力、调节肠道微生物菌群区系结构;此外,酵母多糖还可吸附霉菌毒素等有害物质以提高畜禽生长性能。研究表明,酵母多糖可以提高仔猪和育肥猪的生长性能以及母猪的繁殖性能。本文综述了酵母多糖的组成结构和生物学功能,并总结了对其在生猪养殖上的应用,为酵母多糖在养猪生产实践中的应用提供科学依据和数据支持。Yeast cell wall polysaccharides,also known as yeast polysaccharides,as a kind of secure and effec-tive feed additive,have multiple biological functions,such as enhancing the immunity of animal body and reg-ulating the structure of intestinal microflora.In addition,it can also adsorb mycotoxins and other harmful sub-stances to improve the growth performance of livestock and poultry.Literatures have reported that yeast poly-saccharides could improve growth performance of piglets and finishing pigs and reproductive performance of sows.This paper reviewed the compositional structure and biological function of yeast polysaccharides,and summarized the application in pig breeding,so as to provide a reference basis and data support for the applica-tion of yeast polysaccharides in pig production practice.
