摘　　要：仔猪超早期隔离断奶造成了所谓的“早期断奶综合症”，小肽营养素近几年来在动物营养尤其在超早期断奶仔猪中的应用优势逐渐引起了人们的关注，它能使仔猪肠绒毛长度增加、隐窝深度减小、各种消化酶活性显著增加、免疫系统更好地发育等优点，不失为一条解决“早期断奶仔猪综合症”的好途径，并从小肽的吸收机制、营养作用等方面阐述了小肽对断奶仔猪生长表现的影响。as we all known, there is a syndrome of segreted early weaning piglets that lagged the growth performance very much , mini -peptides has called much more attention in the nutrition field especially for SEW piglets recent years , which can increase the average daily gain and decrease the feed ：body weight ,at the same time ,the villi heights of duodenum,jejunum and ileum were longer and the crypt depths were lower. In addition , MP could improve the development of piglets＂ immune system ,increase the IgG concentration in serum and decrease the diarrhea rate . so it is a good way to solve the problem in SEW with MP. at last the paper also give some expression about the mechanism of MP absorbtion and so on.
