Abstract

Studies have established the effect of ekobentokorm (TU 9283-199-10514645-13-2013) on the metabolism of cows and the natural resistance of young black-and-white breed. The physiological state of cows was assessed by morphological and biochemical studies of blood, in which changes in the body’s metabolic processes were tracked in dynamics according to the following indicators: the number of red blood cells and hemoglobin level, total protein and protein fractions, glucose, urea, aminotransferases (AST, ALT), total calcium and inorganic phosphorus, trace elements (Mg, Zn, Fe, Cu) and carotene. The indicators characterizing the natural resistance of young animals were studied: red blood cells, white blood cells, hemoglobin, color index, total protein and protein fractions, phagocytic activity of neutrophil granulocytes, bactericidal and lysozyme activity of blood serum, the content and concentration of T-and B-lymphocytes, the level of circulating immune complexes (CIC). As a result of the conducted research, it was found that ekobentokorm has high biological activity, improves morphological and biochemical parameters of cows blood, and also increases milk productivity. It has a pronounced stimulating effect on the immunocompetent systems of the body of young animals, as a result of which the level of non-specific protection of the animal increases.
