内源合成以及传统饲粮供给的精氨酸并不能满足母猪的最佳营养需要,因此需外源添加,其对母猪胎盘、胚胎和胎儿的生长发育具有重要意义。本文从精氨酸的理化特性、合成与分解代谢以及对母猪繁殖性能的影响等方面阐述精氨酸的营养生理作用,重点阐述精氨酸营养调节母猪繁殖性能的作用机制。
Arginine from endogenous synthesis as well as the traditional diet provision can not satisfy the optimal requirement of sows.Extra dietary supplementation of arginine is of great significance in improving the growth and development of placenta,embryo and fetus in sows.The present article reviewed the nutritional and physiological effects of arginine,including the physical and biochemical characters,anabolism and catabolism,and its effects on the reproductive performance of pregnancy sows,and especially focused on the regulating mechanism to reproductive performance of sows.
