The influence of local fodder additives on biochemical indices of blood serum of Simmental breed in the conditions of Yakutia

The purpose of the study was to obtain experimental data on the influence of local feed additives on biochemical parameters of blood serum of dairy cows of the Simmental breed in the conditions of Yakutia. In scientific experiment conducted on the cows of Simmental breed positive effect of local feed additives on biochemical parameters of blood serum was established. It should be noted that in our studies the total protein content of the blood serum of experimental animals was within physiological norm. A certain advantage in the content of total protein was found in the cows of the second experimental group; the dynamics of protein fractions showed that the highest concentration of globulins in blood serum had been in the cows of the second experimental group for the period of the experiment. So the content of α-globulins in blood serum was 12.9 g/l, β-globulins was 9.9 and γ-globulins was 20.2 g/l. The difference between the groups in the content of albumin and globulin was insignificant (P
