The breed features of different breeds of pigs for the studied genes (ESR, NCOA1, PRLR, FSHR) were identified. Frequencies of genotypes and alleles of the Ukrainian meat in pigs, Welsh and Large White breeds were calculated. Genotype frequencies of pigs of Large white breed accounted for genes ESR (A - 0.47, B - 0.53, AA - 0.14 AB - 0.66, BB - 0,20), NCOA1 (A1 - 0.78, A2 - 0.22, A1A1 - 0.63, A1A2 - 0.28, A2A2 - 0,09), PRLR (A - 0.49, B - 0.51, AA - 0.33 AB - 0.32 , BB - 0.35). Genotype frequencies of the Ukrainian meat breed pigs were in genes ESR (A - 0.52, B - 0.48, AA - 0.15 AB - 0.75, BB - 0,10), NCOA1 (A1 - 0.63, A2 - 0.37, A1A1 - 0.46, A1A2 - 0.36, A2A2 - 0,18), PRLR (A - 0.42, B - 0.58, AA - 0.35 AB - 0.13 , BB - 0,52), FSHR (C - 0.73, T - 0.27 SS - 0.56 CT - 0.34 CT - 0.10). Genotype frequencies of pig breeds of Wales were in genes ESR (A - 0.60, B - 0.40, AA - 0.22 AB - 0.76, BB - 0,02), NCOA1 (A1 - 0.66 A2 - 0.34, A1A1 - 0.57, A1A2 - 0.20, A2A2 - 0,23), PRLR (A - 0.47, B - 0.53, AA - 0.28 AB - 0.38 BB - 0,34), FSHR (C - 0.75 T - 0.25 SS - 0.57 CT - 0.33 CT - 0.10). Genotype frequencies were Landrace breed pigs for genes ESR (A - 0.53, B - 0.46, AA - 0.15 AB - 0.74, BB - 0,09), NCOA1 (A1 - 0.89, A2 - 0.11, A1A1 - 0.80, A1A2 - 0.18, A2A2 - 0,02), PRLR (A - 0.33, B - 0.67, AA - 0.22 AB - 0.22 BB - 0.56).
