胍基乙酸在羊生产中的应用研究进展OACSTPCD
Research progress on application of guanidinoacetic acid in sheep production
胍基乙酸(GAA)是脊椎动物合成肌酸的重要前体,同时也是一种新型营养性饲料添加剂.由于良好的性价比和生物利用度以及比肌酸更为稳定的特性,胍基乙酸已逐渐成为动物饲料中肌酸的替代品,并在国内外畜牧行业中得到广泛应用.在动物生产中,胍基乙酸的作用主要体现在提高能量供应、节约精氨酸、促进机体生长、改善瘤胃环境、促进瘤胃发酵以及提升肉品质等方面,为养殖业带来了较好的经济效益.文章综述了胍基乙酸的理化性质、代谢过程、生物学功能及其在养羊生产中对生长性能、瘤胃发酵、羊肉品质等方面的影响,以期为胍基乙酸在反刍动物生产中的进一步应用提供参考.
Guanidinoacetic acid(GAA)is an important precursor of creatine synthesis in vertebrates,and is also a new nutritional feed additive.Due to its good cost performance and bioavailability,as well as its more stable characteristics than creatine,guanidinoacetic acid has gradually become a substitute for creatine in animal feed,and has been widely used in the animal husbandry industry at home and abroad.In animal production,the role of guanidine acetic acid is mainly reflected in improving energy supply,saving arginine,promoting body growth,improving rumen environment,promoting rumen fermentation,and improving meat quality,etc.,which has brought good economic benefits to the aquaculture industry.In this paper,the physicochemical properties of guanidine glycolic acid,the metabolic process of guanidine glycolic acid,the biological function of guanidine glycolic acid,and the effects of guanidine glycolic acid on the growth performance,rumen fermentation,mutton quality,and other aspects of sheep production in sheep breeding were reviewed,in order to provide a reference for further application of the guanidine glycolic acid in ruminant sheep production.
