γ-氨基丁酸及其在畜禽生产中的研究进展

摘要

γ-氨基丁酸(γ-aminobutyric acid,GABA)是一种在动物体内起神经镇定作用的非蛋白质氨基酸,广泛存在于哺乳动物中枢神经系统、外周神经系统和一些内分泌细胞中,是一种重要的神经抑制性递质,对提高畜禽采食量、泌乳量、成活率、抗应激、降低呼吸频率、缩短发情间隔等方面有着显著的效果.作者对GABA的制备、生理功能及在畜禽生产中的研究现状作了简要综述.%γ-aminobutyric acid (GABA) is a non-protein amino acid to play neural stabilization role in animal body, exists widely in the central nervous system, the peripheral nervous system and some endocrine cells of mammals. It is an important neural inhibitory neurotransmitter, which has a significant effect on improving animal intake, milk yield, survival percentage and stress response, reducing breathing rate, shortening estrous interval, and so on. This article delivers a brief summary on the preparation and physiological function of GABA and its research status in the livestock and poultry production.
