抗菌肽的生物学功能及在家禽养殖中的应用研究进展

Research progress on biological functions of antimicrobial peptides and application in poultry

抗菌肽(animal antimicrobial peptides,AMPs)是广泛存在于自然界的一类小分子碱性多肽,具有多种生物学功能,且不易产生耐药性,是一种比较理想的抗生素替代添加剂。文章综述AMPs的理化特性及分类,阐述AMPs的生物学功能及作用机制,重点介绍AMPs在家禽养殖中的应用效果及研究进展,以期为畜牧生产者提供有效参考。

AMPs are a class of small molecule alkaline peptides that widely exist in nature,which have multiple biological functions and are not prone to drug resistance.They are an ideal alternative to antibiotics.The article reviews the physicochemical characteristics and classification of AMPs,elaborates on their biological functions and mechanisms of action,focuses on the application effect and research progress of AMPs in poultry farming,to provide effective references forlivestock producers.
