精氨酸对断奶仔猪肠道健康的影响及相关机制

摘要

精氨酸是体内合成蛋白质、一氧化氮、鸟氨酸、多胺等生物学重要分子的前体物，在肌肉蛋白质合成、机体免疫力调控、细胞分裂、伤口复原等生理过程中都有着重要作用。本文总结了断奶仔猪精氨酸需要、代谢特点及其在改善肠道黏膜结构及功能中的作用，同时阐述了精氨酸促进肠黏膜生长及修复、改善肠道免疫功能的可能机制。%Arginine is the precursor of many important biological molecules,such as protein,nitric oxide,or-nithine,polyamine and so on. It is important in muscle protein synthesis,immune regulation,cell division, wound recovery and other physiological processes. This review summarized the need of arginine and its meta-bolic characteristics,and its role in improving the structure and function of intestinal mucosa in weaner piglets. The mechanisms of arginine on promoting growth and repairing intestinal mucosa were also summarized.
