Abstract: As the component of cell wall,fiber is the most widely distributed and abundant renewable resource on the earth. As the most important component of fiber structure besides lignin,non-starch polysaccharide(NSP)plays an important role in the functional regulation of fiber. The mechanism of fiber regulation in intestinal microflora has become a hot topic in the field of microbiology. However,as a complex mixture,the results of studying fiber are not consistent. The difference in fiber source,NSP content,and the incomplete assessment system are the reasons for the diverse results. In this paper,the research of NSP on the regulation of intestinal microflora in pigs in recent years was reviewed,and also the significance and problems of NSP in assessing the balance between dietary fiber and intestinal microflora were discussed,aiming to further expound the dialogue mechanism between nutrients and intestinal microflora and to provide reference for promoting the intestinal health of animals and the rational utilization of fiber.

Key words: pig, fiber, non-starch polysaccharide, intestinal microflora
