Dynamics of growth, immunogenesis and the metabolism at bull-calves at appointment of new biological preparations

Experimentally proved the physiological expediency of the combined appointment of immunomodulators «Sedimin-Se +» and «Kombiolaks» to bull-calves. At the same 180 -, 360 - and 540-day-old animals at the end of the period of cultivation, rearing and feeding significantly superior to intact peers on body weight, number of erythrocytes, hemoglobin concentration, activity autoantibody-plaque-forming cells in blood, levels of total protein, albumin, γ-globulins, immunoglobulins, acid tanks, peroxide oxidation of lipoproteins activity in her serum, and activity of peroxidase, alkaline phosphatase and antioxidant system, on the contrary, – inferior.
