- Abstract
Hair follicle is a regenerative organ, and its growth process constantly goes through the cycle of growth, decline and rest period. The cyclic growth of hair follicle determines the growth and loss of fur. Hair follicles are not only regulated by genetic, environmental, and other factors, but also closely related to the content and type of nutrients in the diet, especially the protein content and amino acid composition. Protein is an important substance in the composition of fur animal coat. Sulfur-containing amino acids are the main amino acids that restrict the growth of coat. Sulfur elements exist in the coat in the form of disulfide bonds, which play an important role in maintaining the network space structure of coat fibrin molecules and resisting the erosion of various adverse factors from the outside world. In addition, lysine, tryptophan, tyrosine, glutamic acid, and other non-sulfur-containing amino acids are also involved in the formation of fur animal skin sheets, which play an important role in controlling fur animal skin coat color, promoting coat growth and regulating fur maturation. In this paper, the recent research progress on the effects of protein content and amino acid composition in feed on fur quality of fur animals is reviewed, in order to provide a reference for guiding the genetic selection and production of fur animals.
