Vitamin A

Vitamin A is used to produce premixes, formulated feed and feed mix for farm livestock for prophylaxis of hypovitaminosis A. Vitamin A exists in organism fabrics in the form of retinolum, visual yellow and retinoic acid. In fabrics retinolum passes into retinolum phosphate, a carrier of the remains of mannose and the galactoses, necessary for synthesis of glycoproteins and mucopolysaccharides which provide growth of cages and secretion of slime of covers. Getting to an organism of a bird or animals together with a forage, vitamin A from a small intestine arrives in blood, and then it is deposited in a liver in the form of esters of acetic and palmitic acids. Vitamin A positively influences many processes which are taking place in an organism: integument regeneration, growth, reproductivity, resilience to infections, remaking of antibodies, synthesis of visual purple (rhodopsin), metabolism of proteins, fats, carbohydrates.
