The paper presents the study results of the absolute indicators of the reproductive qualities of sows of different intrabreed differentiation according to the breeding index of reproductive qualities of the sow (BIRQS) and the index of M. D. Berezovskyi, as well as the calculation of the economic efficiency of their use in the conditions of a controlled population. The research was carried out in the breeding breeder for breeding pigs of the large white breed of the experimental farm and the laboratory of animal husbandry and fodder production of the Institute of Agriculture of the North-East of the NAAS, as well as the laboratory of animal husbandry of the State Institution of Grain Crops of the NAAS. Evaluation of sows for reproductive qualities was carried out considering the following signs: multifertility, high fertility, nest weight at the time of weaning at 28 days, preservation. Comprehensive evaluation of sows for reproductive qualities was carried out according to the selection index of reproductive qualities of the sow (BIRQS) (Tsereniuk et al., 2010) and the index of M. D. Berezovskyi (Vashchenko, 2019). Biometric processing of research results was carried out according to generally accepted methods (Kovalenko et al., 2010). Taking into account the intrabreed differentiation according to the selection index of the reproductive qualities of the sow (BIRQS) and the index of M. D. Berezovskyi, a significant difference was established between the sows of the I and III experimental groups in terms of multifertility (2.8-2.4 heads), as well as the weight of the nest at the time of weaning at the age of 28 (16.9-16.0 kg) and 60 days (45.2-43.0 kg). The maximum indicators of high fertility and survival of piglets until weaning at the age of 28 days were found in sows of the III group of intrabreed differentiation according to the breeding index of reproductive qualities of the sow (BIRQS) and the index of M. D. Berezovskyi. The number of reliable pairwise correlation coefficients between the absolute indicators of reproductive qualities of sows, the index of M. D. Berezovskyi and the selection index of reproductive qualities of the sow (BIRQS) is 92.85%. The criteria for selecting highly productive sows are the following indicators: according to the index of M. D. Berezovskyi – 40.63-44.37 points, the selection index of reproductive qualities of the sow (BIRQS) – 98.13-108.98 points. The maximum increase in additional production was obtained from sows of the 1st experimental group of intrabreed differentiation according to the index of M. D. Berezovskyi (+9.49%) and the selection index of reproductive qualities of the sow (BIRQS) (+9.00%), and its value was +1002.92 and +951.14 UAH/head/farrow, respectively
