Abstract
The possibility of using of domestic biologics of new generation Prevention-N-A-M and PS-7 was studied in order to activate the nonspecific resistance of the animal organism. The article presents data on the morphological parameters of the blood of animals (the number of erythrocytes, leukocytes and the content of hemoglobin). The positive effect of the tested biologics on morphological parameters of blood was established. The increase of the number of erythrocytes and the concentration of hemoglobin in the blood of down-calving and freshly calved cows indicates that the introduction of biologics Prevention-N-A-M and PS-7 contributes to the activation of hematopoiesis in animals of the experimental groups. The established changes in the number of leukocytes in the blood of experimental animals on the background of intramuscular injection of biologics indicate the activation of cellular factors of nonspecific protection of the body. Data on differential leukocyte count will be presented in message 2. The results of the study make it possible to scientifically substantiate the feasibility of using biologics in animal husbandry as an effective way to increase the resistance of the body of cows, which can significantly improve their health and reduce the risk of diseases.
