Nonspecific resistance of the body of cattle against the background of the use of biological products

A method for the prevention of diseases of the postpartum period and the implementation of the biological resource of reproductive qualities of black-and-white cattle due to the activation of nonspecific resistance of the body of pregnant cows with biological products is proposed. It was found that in cows of the 1st and 2nd experimental groups, in which biological products were used, the separation time of the placenta was 5.2 and 5.9 hours less than in the control. The first sexual heat in the cows of the 1st experimental group began 12.0 days earlier, and in the 2nd experimental group - 14.6 days earlier than in the control. Intramuscular injections of biologicals Prevention-N-C and Salus-PE in cows for 45-40 days, 25-20 and 15-10 days. Before calving, cellular nonspecific defense factors were activated and increased the body's resistance to stress, with a more pronounced corresponding effect of Salus-PE tested for the first time.
