非淀粉多糖在猪肠道菌群调控中的研究进展

摘要/Abstract

摘要： 纤维作为高等植物细胞壁的主要组成部分,是地球上分布最广、储量最丰富的可再生资源。而非淀粉多糖（Non starch polysaccharide,NSP）作为纤维结构中除木质素外,最重要的构成组分,在纤维的功能性调控中扮演着重要的角色。纤维对肠道菌群调控的机制研究已成为当前微生物领域研究的热点,但其研究结果存在不一致性。纤维源的不同、NSP组分的差异及其评价体系的不完善,均是导致其应用效果呈现多样性的重要原因。就近几年有关NSP对猪肠道菌群调控中的研究进行综述,讨论了NSP在评价日粮纤维与肠道微生物区系平衡中的意义及存在的问题,旨在为进一步揭示营养素与肠道菌群的对话机制,促进动物肠道健康及纤维的合理利用提供借鉴。

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.
