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
