Abstract

The article presents data on the study of the effectiveness of a probiotic supplement based on inactivated biomass of the fungus R.citrinum and B.subtilis on biochemical blood parameters and immunological status in pigs on feed. The study was conducted on 15 crossbreeds (F1:(DhL) during the fattening period with an initial live weight of 20–25 kg at the age of 45 days. The duration of the study is 45 days. The inclusion of the probiotic additive Cytosporin based on B.subtilis VKM B-3171D, In the composition of full-fledged compound feeds of experimental groups of growing fattened young pigs. B.licheniformis VKM B-3172D, inactivated biomass of the fungus R.citrinum VKM B-4930D provides an increase in urea and creatinine by 20.9% (P<0.05) and 6%, respectively, and glucose concentration by 13.5% and 25.4% (P<0.05) higher relative to the control group. During the study, a decrease in the number of salmonella and enterococcus in the experimental groups was reliably recorded, which confirms the effectiveness of the use of the probiotic additive Citrosporin.
