The aim of the study was to investigate the effect of the probiotic preparation Baykal EM-1 on the growth performance, blood parameters and behaviour of weaned pigs. А research experiment with a total of 96 growing pigs, divided into two groups - control (48) and experimental (48), fed with the probiotic Baykal EM-1 in the amount of 10 ml/kg feed, was carried out. The indicators average live weight, feed consumption, daily gain, feed conversion, blood parameters and behaviour of pigs, were studied. The following conclusions were made: The addition of Baykal EM-1 (10 ml/kg feed) in weaned pig diets improved the average daily gain by 11% (P = 0.031). The higher number of leukocytes and lymphocytes in pigs from the experimental group (P<0.001), compared to the control group, may be an indicator of better health and higher immunity. A trend for better comfort in animals with the microbiological supplement in the feed, contributing to the better absorption of nutrients, has been established. The results obtained in this study show that the combination of probiotics Baykal EM-1 has the potential for use as a dietary supplement in weaned pigs.
