It was established that during the research period, the amount of lactic acid microorganisms in the rumen of calves of control and test subgroups decreased. The number of lactic acid microorganisms in the rumen of calves decreased by 1.15-1.18 times in control subgroups during the first month of studies. It was established that in calves of the control subgroups of the autumn-winter period of birth during the appearance of the ruminant process the activity of acid phosphatase of blood serum was 1.05–1.15 times less than that of the experimental subgroups of calves. The lysozyme activity of blood serum in calves of the autumn-winter period of birth of control subgroups averaged 26.30 ± 0.56%. In calves of the experimental subgroups, LASK was found to be 7-8% higher at the time of the appearance of the ruminant activity. On the 45th day of age, LASK indicator in control and experimental subgroups increased by 1.64 times compared to this indicator at the time of the appearance of the ruminant process. On the 180th day of studies BASK indicator in calves of control subgroups of the autumn-winter period of birth, depending on the body weight at birth, increased by 1.32; 1.36; and 1.38 times respectively, and by 1.36 times on the average compared to the indicators on the 90th day of age. By day 180 the bactericidal activity of blood serum in calves of experimental subgroups increases by 1.33, 1.28; 1,33 times, respectively, and by 1,31 times on the average in comparison with the given indicator on day 90. In calves of control subgroups that were born in the winter-spring period, BASK was at the level of 30.45 ± 0.87% by the time of ruminant process appearance. This indicator in calves of experimental subgroups was 1.08 times higher. Subsequently, the bactericidal activity of the blood serum of calves of the control and experimental subgroups of the winter-spring birth period increased consecutively by 1.5 to 1.50 times by day 180 of life respectively.
