The importance in intensifyin g the reproduction of pigs, increasing the fertility of the broodstock, as in any industry, is associated with the breeding of pigs, and the reproduction of the herd plays the main role in increasing the profitability of pig bree-ding. The object of the study were hybrid Landrace-Large White sows. The purpose of our research was to test a method for increasing the reproductive function and productivity of pigs using a new drug obtained from beer production waste. It was found, that feeding sows a biologically active drug (MP-MB) 30 days before farrowing and within 30 days after farrowing in the amount of 5, 10, 15 and 20 ml per head per day has a significant effect on the average daily gain in live weight of piglets, contribu-tes to a decrease in the number of stillborn piglets, an increase in live ones per farrow and the safety of piglets at 2 months of age.
