摘　　要：甜菜碱及其盐酸盐,是一种营养性饲料添加剂,作为甲基供体参与体内蛋氨酸循环。近期研究发现,甜菜碱主要通过降低同型半胱氨酸浓度、增加繁殖相关激素含量等途径提高畜禽的繁殖性能,也具有调控能量代谢、抗应激的作用。作者就甜菜碱对畜禽繁殖性能的影响及其作用机理进行简要综述。Betaine is a nutritional feed additive acting as a methyl donor involved in the methionine cycle.Recently,studies have found that betaine may improve the reproductive performance of livestock and poultry,mainly through decreasing homocysteine concentration and increasing the reproductive-related hormones.It also has effects on regulation of energy metabolism and antistress.This article will review the effect of betaine on reproductive performance of livestock and poultry and its mechanism.
