胍基乙酸和甜菜碱的生理协同功能及其在反刍动物生产中应用的研究进展

Research progress on physiological synergistic function of guanidinoacetic acetic acid and betaine and its application in ruminant production

胍基乙酸是一种氨基酸类饲料添加剂,是动物机体内合成肌酸的唯一前体物质。肌酸是合成磷酸肌酸组分之一,补充胍基乙酸可以间接提供能量。甜菜碱是良好的甲基供体,具有调节细胞渗透压、缓解应激反应、提高动物生长性能、改善肉品质以及减少脂质沉积的功能。因此,胍基乙酸和甜菜碱对动物机体生长具有积极的作用。文章阐述了胍基乙酸和甜菜碱的生理功能、协同作用以及二者单独使用、联合使用对反刍动物生产性能的影响,以期为其在动物生产实践中的应用提供参考。

Guanidinoacetic acid is an amino acid feed additive and the sole precursor for the synthesis of creatine in animal body.Creatine is one of the components for synthesizing phosphocreatine,providing indirect energy supplementation.Betaine serves as an excellent methyl donor,contributing to the regulation of cell osmotic pressure,alleviation of stress responses,enhancement of animal growth performance,improvement of meat quality,and reduction of lipid deposition.Therefore,guanidinoacetic acid and betaine play positive roles in the growth of animal bodies.The article elucidates the physiological functions,synergistic effects,and the impact of their separate and combined use on the production performance of ruminants.The aim is to provide references for their practical application in animal production.
