摘　　要：生物活性肽是一类具有特殊生物学功能的氨基酸序列多肽片段,主要通过发挥抗菌、抗炎、免疫和抗氧化等功能改善机体健康。肠道是动物消化吸收营养物质的主要器官,良好的肠道环境对维持机体健康至关重要。生物活性肽可通过改善肠道形态和黏膜功能、增强肠道免疫和抗氧化功能、调节肠道菌群及其代谢产物等途径维持肠道稳态、改善肠道健康。本文综述了常见生物活性肽的功能特性及其对畜禽肠道健康的调控机制,以期为在畜禽生产中的应用和新型生物活性肽的开发提供参考。Bioactive peptides are a class of amino acid sequence polypeptide fragments with special biological functions,mainly through antibacterial,anti-inflammatory,immune and antioxidant functions to improve body health.Intestinal tract is the main organ for animals to digest and absorb nutrients,and a good intestinal environment is very important for maintaining body health.Bioactive peptides can maintain intestinal homeostasis and improve intestinal health by improving intestinal morphology and mucosal function,enhancing intestinal immune and antioxidant function,and regulating intestinal flora and its metabolites,etc.In this paper,the functional properties of common bioactive peptides and their regulatory mechanisms on intestinal health of livestock and poultry were reviewed,with a view to providing references for their application in livestock production and the development of novel bioactive peptides.
