摘要

色氨酸作为一种功能性必需氨基酸,可提高动物生长性能、调节采食与泌乳、增强机体抗氧化和免疫功能等。色氨酸作为饲料添加剂应用于低蛋白质饲粮中,在保证动物正常生产性能情况下,可减少蛋白质饲喂量,缓解蛋白质饲料原料紧缺问题,减轻养殖废弃物对环境造成的污染。本文从色氨酸在畜禽体内的代谢途径及其对畜禽的生理功能等方面进行综述,为色氨酸在畜牧生产中的科学合理应用提供参考。

Abstract

Tryptophan, as a functional essential amino acid, plays important roles in improving growth performance, modulating feed intake and lactation, enhancing anti-oxidative and immune functions, and so on in animals. When used as a dietary additive to a low-protein diet, tryptophan will reduce dietary protein level, but not alter production performance of animals, which results in relieving the current protein deficiency and decreasing the environment pollution caused by the waste of animal production. This paper reviewed the metabolic pathways and physiological functions of tryptophan in livestock and poultry in order to provide knowledge for scientific and reasonable application of tryptophan in animal production.
