The association of heart fatty acid binding protein gene polymorphism on selected production traits in pigs

Anton Kováčik

Abstract


Heart fatty acid-binding protein (H-FABP) gene, a candidate gene of IMF, is located on pig chromosome six and is expressed in various tissues This study aimed to investigate the associations of H-FABP polymorphism with selected traits (half carcass weight, lean meat percentage, back-fat thickness, MLT area - musculus longisimus thoracis,drip loss, average daily gain) and evaluation of genotypic values, additive values and dominance deviations. To identify the genotypes of H-FABP candidate gene, we used biological material obtained from sows (55) and boars (51) of hybrid combination Large White x Landrace after reaching the slaughter weight. We identified three genotypes using restriction endonuclease HinfI in a group of 106 pigs. The HH genotype was the dominant one (48.11%), Hh heterozygotes constituted 38.68%, while the hh genotype was the lowest (13.21%). Analyzing the half carcass weight, lean meat percentage, back-fat thickness were results very balanced. The pork genotype hh presented the highest back-fat thickness. A high correlation between the additive genetic effect of the h allele and MLT area (1.4295) has been observed while the effect of the allelic dominance was relatively low (0.2092). For the other traits, we did not record significant differences between genotypes.
