苏氨酸对猪生理作用的研究进展

Research Progress on Physiological Effects of Threonine in Pigs

苏氨酸是猪饲粮中重要的限制性氨基酸,具有促进蛋白质合成、调节脂质代谢、参与机体免疫功能调控等作用。研究发现,在猪饲粮中添加苏氨酸可以调整饲粮氨基酸平衡,提高猪采食量及生长速度。本文就苏氨酸的代谢途径、作用机制以及苏氨酸对猪生理上的作用和在猪生产中的特殊意义进行总结,旨在为苏氨酸在猪生产中的应用提供参考。

Threonine is an important limiting amino acid in pig diets,which can promote protein synthesis,regulate lipid metabolism and participate in the regulation of immune function.Previously,studies have found that supplementation of threonine in pig diet can adjust the balance of dietary amino acids and improve the feed intake and growth rate of pigs.In this paper,the metabolic pathway and mechanism of threonine,the physiological effects of threonine and the special significance of threonine in pig production were summarized,so as to provide reference for the application of threonine in pig production.
