摘要：

早期断奶是现代养猪生产中的瓶颈问题。早期断奶易造成仔猪早期断奶综合征，仔猪断奶后会出现采食量下降、生长阻滞和腹泻等一系列症状。引起这些症状的主要原因之一是断奶应激引起的仔猪肠道屏障受损。鉴于肠道微生态区系为肠道第一道防御屏障，因此，研究仔猪肠道微生态区系及其营养调控技术，对于防制仔猪早期断奶综合征、促进仔猪肠道健康、提高生产性能具有重要意义。文章针对断奶仔猪肠道微生物菌群变化及几种常用饲料添加剂（微生态制剂、植物多糖、酸化剂、微量元素、中草药及植物提取物）对肠道微生态区系调控的研究进展进行了综述。

Abstract:

In modern pig production,early weaning is a bottleneck problem which are restricting the development of pig industry.It can lead to early weaning syndrome in piglet,such as low appetite,growth inhibition,diarrhea and so on.One of the reasons induced these symptoms is impairment of intestinal mucosal barrier in piglets.The intestinal microflorais is one of the important parts of intestinal mucosal barrier.Therefore,study on the intestinal microflora of weaning piglets and nutritional regulations have been attracted more and more attentions,and it has an important influence on avoiding diarrhea,promoting the healthy growth and improving growth performance.The change of intestinal microflora in weaning piglets and research development of some common feed additives（microecologics,plant polysaccharide,acidulant,microelement,Chinese herbal medicine and plant extracts）for intestinal microflora were reviewed in this paper.

Key words: weaning piglets; intestinal mucosal barrier; microbiota; nutrition regulation
