摘　　要：甜菜碱是甘氨酸的三甲基衍生物。作为饲料添加剂,甜菜碱具有促进动物生长、改善胴体品质、缓解热应激、调控动物繁殖性能等作用。甜菜碱可以通过参与蛋氨酸代谢为机体大部分甲基化反应提供甲基。近年来,越来越多的研究揭示了甜菜碱通过调控表观遗传影响动物繁殖的作用。本文综述了甜菜碱对猪和家禽生长和繁殖的影响及其作用机制,以期为甜菜碱在畜禽生产中的合理应用提供新的思考。Betaine is trimethyl derivative of glycine.As feed additive,betaine plays important roles in promoting animal growth,improving carcass quality,relieving heat stress and modulating reproductive performance.Through participating in methionine metabolism,betaine provides methyl to most methylation reactions of the organisms.In recent years,more and more researches have revealed the role of betaine in impacting animal production through epigenetic regulation.This paper summarizes the effects of betaine on pig and poultry growth and reproduction and its mechanism aiming at providing new thought for the rational application of betaine in animal production.
