Abstract: Valine is a functional amino acid which regulates multiple biological processes, including protein synthesis, lipid metabolism, glucose metabolism, antioxidant defense and immunity. Valine supplementation is one of the critical means to develop low protein diets for livestock and poultry, which plays an important role in promoting the growth of livestock and poultry as well as modulating lactation and egg production. This paper summarizes the latest research status at home and abroad, reporting the sources, classifications, metabolic pathways, interactions with other amino acids, biological functions of valine and its application research progresses in the diets of monogastric animal and ruminant. This review also points out the current issues of valine application in the diets of livestock and poultry, and provides the theoretical basis for the scientific, efficient and extensive application of valine in the diets of livestock and poultry.

Key words: valine, livestock and poultry, metabolic pathway, biological function, research progress
