ANTIOXIDANT REGULATION OF THE BODY OF DRY COWS AS A FACTOR OF PREVENTION OF NEONATAL DISEASES IN CALVES
In modern dairy farming an important problem is to ensure the high survival rate of young animals in the early postnatal period. In the first days of calves' life the leading place is occupied by diseases of the gastrointestinal tract, manifested by diarrhea, dehydration, dysbiosis, toxemia and immunodeficiency. The article presents data on the study of the effectiveness of the use of the Hepavitol drug in cows during the dry period. Hepavitol is an injectable drug, which is an oily solution of beta-carotene, selenium and phospholipids. It was found that in conditions of increased generation of free radicals in the body of cows (which include the pre-maternity period and calving), when the chain self-induced mechanism of free radical reactions goes beyond the stationary level, the use of Hepavitol ensures the optimization of lipid peroxidation processes, which helps to reduce the development of gastrointestinal diseases in calves in the postnatal period.
