The leptin (LEP-HinfI), leptin receptor (LEPR-HpaII) and heart fatty acid binding protein (H-FABP-HinfI) genes and their genotypes combination (LEP-HinfI *LEPR-HpaII) were tested for associations with the pH1, pH24, myoglobin content (mg/100 g), intramuscular fat content (%) and remission (%). The genotypes were determined in Large White, Landrace and Duroc breeds (n = 106, 56 and 4, respectively). The allele frequencies were: LEP-HinfI: C = 0.133 T = 0.867; LEPR-HpaII: A = 0.331 B = 0.669; H-FABP-HinfI: H = 0.745 h = 0.255. The populations of breeds were in the genetic equilibrium according to the χ2 test in the tested loci. The combinations of LEP-HinfI and LEPR-HpaII were significantly associated with the pH24 and remission. The H-FABP-HinfI locus was significantly associated with intramuscular fat content.
