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 lees or equal 0.01), feed intake (p less or equal 0.001) and feed conversion (p less or equal 0.001), in favor of the AG genotype.We observed a weak association between the A303G polymorphism system and carcass (MLT - p less or equal 0.05) and physicochemical (pH 1 MLT - p less or equal 0.05) characteristics. No significant differences were found in other parameters.
