The aim of this paper was to investigate the associations between MC5R gene polymorphism (A303G) and feed intake, carcass and physicochemical traits in Large White x Landrace crossbred pigs. The experiment was conducted on 106 pigs (LW x L). The polymorphism of MC5R gene was analyzed by PCR-RFLP method using the BsaHI restriction enzyme. Two genotypes were identified, AA (72.64%) and AG (27.36%) genotype.In the test group we found clearly observed a higher frequency ofA allele(0.8633) compared with the G allele (0.1367).In this study, significant differences were observed in MC5R (BsaHI) between genotypes for ADG (p ≤ 0.01), feed intake (p ≤ 0.001) and feed conversion (p ≤ 0.001), in favor of the AG genotype.We observed a weak association between the A303G polymorphism system and carcass (MLT - p ≤ 0.05) and physicochemical (pH 1 MLT - p ≤ 0.05) characteristics. No significant differences were found in other parameters.
