PROPHYLAXIS OF ANTIOXIDANT INSUFFICIENCY IN NEWBORN CALVES

Abstract

Forty newborn calves were divided into four equal groups. The experimental groups were treated with the antioxidants vitamins A, E, C and rutin, as well as a new preparation placenta denatured emulsion (PDE). The results showed the immaturity of the antioxidant system in newborn calves. Neonatal calves have low antioxidant activity at birth and during the first two weeks of life. Calves are born with a high erythrocyte peroxidation index. The stabilization of erythrocyte membranes take place by one month of age. This is indicated by the level of erythrocyte peroxidation and the concentration of malondialdehyde (MDA) found in the blood serum. All treatments had a significant effect on the antioxidant activity of the newborn calves. Erythrocyte peroxidation was decreased during the first three weeks. Combinations of vitamins A, E, C and rutin gave more conclusive results.
