摘　　要：抗菌肽是由宿主先天性免疫防御系统产生的一类可抵抗外界病原体感染的小分子阳离子多肽。抗菌肽具有抗菌谱广、对多重耐药菌有良好杀伤作用、热稳定性和水溶性好、对哺乳动物正常细胞几乎无毒害作用等特点,因此在畜牧业中有望替代抗生素成为新一代抗菌添加剂。本文主要就抗菌肽在提高断奶仔猪生长性能、减少腹泻、改善肠道平衡以及促进机体免疫功能等方面的作用进行了阐述。Antimierobial peptides are a family of endogenous cationic peptides produced by innate immune system of hosts, and exert antimierobial activities against pathogenic microorganism infections. Antimicrobial peptides exhibit broad antimierobial spectrums, especially to multi-drug resistant bacteria, good high thermal stability and water solubility, and most important, low toxic effects to mammalian cells. Therefore, antimierobial peptides have the potentials to be substitutes for traditional antibiotics for growth promotion in the livestock industry. This thesis gives a detailed elaboration that antimicrobial peptides increase growth promotion, decrease diarrhea rate, improve intestinal microflora homeostasis, and promoter immune system in weaned piglets
