摘要
甜菜碱又名三甲基甘氨酸,广泛分布在动植物中。其特殊的化学结构,使其在胃肠道和代谢调控过程发挥一系列重要功能。作为甲基供体,甜菜碱参与多种代谢活性成分的合成,如肌酸和肉碱。因此,补充甜菜碱可以降低日粮其他甲基供体蛋氨酸和胆碱的需要量,甜菜碱作为饲料添加剂现已广泛应用于猪生产。本文主要围绕代谢调控和渗透调节两大功能对甜菜碱在猪生产中的应用及其机制作一综述。
Betaine is the trimethyl derivative of the amino acid glycine, and is present in plant and animal tissue. Due to its chemical structure, betaine exerts a number of functions both at the gastrointestinal and metabolic level. As a methyl group donor, betaine is involved in synthesizing several metabolically active substances such as creatine and carnitinc. Therefore, supplementation of betaine may reduce the requirement for other methyl group donors such as methionine and choline in the diet. Due to its various metabolic and osmoregulatory functions, betaine is commercially used in pig production as a feed additive. This review focused on the metabolic and osmoregulatory functions of betaine and its application in pig production.
