日粮纤维对猪肠道微生物影响的研究进展

Research Progress on Dietary Fiber Affecting Intestinal Microorganism of Pigs

肠道微生物不仅为宿主提供营养物质,也有利于维持肠道微生态的平衡,对保证肠道的健康发育至关重要。日粮纤维是肠道微生物发酵的底物之一,能够改善肠道微生物菌群结构。本文从日粮纤维对猪肠道微生物的功效及影响猪肠道微生物利用日粮纤维的因素展开综述,为日粮纤维在生猪生产实践及研究提供一定理论依据。

Intestinal microbes not only provide nutrients for the host,but also contribute to the maintenance of intestinal microecological balance,and are essential for ensuring the healthy development of the intestine.Dietary fiber is one of the substrates for intestinal microbial fermentation,which can improve the structure of intestinal microflora and is of great significance in maintaining intestinal health.In this paper,the recent research progress on the efficacy of dietary fiber on pig intestinal microbes and the factors affecting the intestinal microbial utilization of dietary fiber in pigs is reviewed,which provides a theoretical basis for further research on the production practice of dietary fiber in pig breeding industry.
