Abstract


The aim of this study was to identify polymorphism in LEPR and MC4R genes and evaluate some production traits in 102 pigs. Genotyping of pigs was done by PCR – RFLP methods. Into the set of 102 pigs were found three genotypes AA(14), AB(32) and BB(56) for LEPR gene and AA(46), AG(37) and GG(19) for MC4R. Differences between genotypes were detected. The high determination coefficient was confirmed (0,68 – 0,79). Choises model was statistically highly significant and highly significant LEPR and MC4R genes effect was confirmed for backfat thickness (BFT). Also this study published polymorphism of these genes and their effect on production traits of pigs (mainly lean meat - LM and average daily gain - ADG). The results were obtained on small number of animals and the results have to be confirmed on larger number of animals.
