Effect of vitamins on animal fur and its mechanism
The skin and fur condition is an important indicator judging the growth of animals.Healthy animals always exhibit characteristics of rosy skin and oily hair.The metabolic pathway involved in vitamins plays key roles in the physiological processes of growth,development and reproduction of animals.Particularly,vitamin nutrition directly affects the fur condition of animals.Vitamin A and its derivatives can regulate the exfoliation of dead cells in the stratum corneum and the proliferation of living cells in the epidermis,promoting skin cell renewal and increasing skin elasticity.Vitamin C can eliminate free radicals,reduce oxidative stress damage to the skin,and participate in collagen synthesis and repair by regulating the activity of skin proline and lysine hydroxylase.Vitamin D can regulate the differentiation and proliferation of the epidermis by maintaining normal skin metabolism and promoting hair growth,forming a stable barrier to prevent water loss and the invasion of microorganisms.Vitamin E can prevent lipid oxidation of skin cell membranes and maintain the integrity and stability of cell membranes.B vitamins mainly serve as coenzymes and have regulatory effects on skin elasticity,skin immunity,fur color,and smoothness.Although vitamins are relatively low in feed formulations,they play an important role in animal fur development and other physiological functions.This article reviews the effects and mechanisms of vitamins on animal fur,in order to provide a reference for regulation strategies of animal fur condition.
