The article presents the results of research on the indicators of own productivity of replacement pigs and reproductive qualities of sows of different breeding value and determines the economic efficiency of research results. The study was conducted in agricultural formations of Dnipropetrovsk and Sumy regions, the livestock laboratory of the Institute of Grain Crops of NAAS, and the livestock and feed production laboratory of the Institute of Agriculture North-East of NAAS. The evaluation of replacement pigs on indicators of own productivity and sows on signs of reproductive qualities was carried out taking into account the following parameters: age of achievement of live weight of
Keywords: replacement pig, own productivity, sow, reproductive qualities, breeding value, index, variability, correlation, economic efficiency
