The purpose of this work was to realize the reproductive qualities of sows and the productivity of young pigs with immunotropic preparations PigStim-C and PigStim-M. To set up the experiment, 30 heads of nursing sows were selected on the 15th day after the first farrowing. The selected sows were divided into 3 groups according to the breed, reproductive qualities and reproductive health according to the principle of pairs of analogues. It was found that intramuscular injection of the immunotropic drug PigStim-C to animals of the 1st experimental group (and PigStim-M to animals of the 2nd experimental group) at a dose of 5 ml per head on the 15th, 20th, and 25th day after farrowing contributes to: reducing the period from weaning to coming into heat and the onset of the optimal period for insemination by 4.5-9.1%; an increase in the success of insemination from 90% in the control group to 100%; an improvement in sows’ prolificacy by 8.1-8.6% and a decrease in the number of stillborn piglets by 16.7-33.3%; a decrease in the number of sows with prolonged farrowing by 2-3 times resulting in a decrease in the occurrence of postpartum pathologies of reproductive organs, such as metritis-mastitis-agalactia syndrome, as well as an increase in the therapeutic measures' efficiency in case of their occurence; a decrease in the disease incidence of young pigs obtained from these sows during the next farrowing by 36.8-41.5%, an increase in their viability by 1.45-2.97% and an increase in live weight at the end of the growing period by 0.16-0.18 kg, rearing – by 1.1-1.22 kg, and when removed from fattening – by 3.6-4.0 kg.
