Abstract. The aim of this study was to determine the association between polymorphism located in exon 8 of PPARGC1A gene (Cys430Ser) and carcass quality in pigs. Experiment was carried out on 350 PIC hybrid fatteners. Polymorphism was analyzed using PCR-RFLP method. The frequency of genotypes was as follows: AA – 0.33, AT – 0.57, TT – 0.1, however alleles: A – 0.62, T – 0.38. In the analyzed population loss of Hardy-Weinberg equilibrium was observed (P ≤ 0.01). Statistical analysis showed that only one of the evaluated traits was associated with individual PPARGC1A genotypes. Cooling loss value for pig carcasses with TT genotype was statistically significant (P ≤ 0.05) higher than observed in those with AA and AT genotypes.
