Effect of the fat mass and obesity associated (FTO) gene polymorphism on carcass traits in pigs

Abstract

The aim of this study was to evaluate the effect of FTO single nucleotide polymorphism (g.276T>G) on carcass traits in Large White pigs. In several studies have been suggested that the FTO gene influenced significantly regulation of energy balance and feed intake in pigs and therefore can be considered as genetic marker for their production traits. We used 150 boars (73) and sows (77) from Large White breed. Genotyping of animals was carried out by PCR-RFLP method with using restriction enzyme TaiI. We identified three genotypes TT (20.66%), TG (66.67%) and GG (12.67%). Associations of FTO gene polymorphism with back fat thickness, lean meat percentage, thigh percentage and MLT area were analyzed. The results of the statistical analyses did not confirmed the effect of the FTO mutation (g.276T>G) on selected carcass traits in analyzed population of Large White pigs.
