Research progress on application of guanidinoacetic acid in sheep production
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.
