Abstract:
:The role of the porcine GH gene was investigated in 292 F2 animals of mating Wild Boar x Piétrain and in 310 F2 animals of mating Meishan x Piétrain. Forty-three traits of fattening, carcass composition, meat quality and stress resistance were recorded. For the analysis of associations between GH gene variants and quantitative traits, two restriction fragment length polymorphisms were examined. In the Meishan x Piétrain family eight traits related to fatness were significantly associated with GH genotypes, while in the Wild Boar x Piétrain family no significant associations were found. In the Meishan x Piétrain cross, the GH locus explained 11.7% to 17.7% of the total phenotypic variance in the F2 population. The possibility of multiple alleles at the GH locus is discussed. Based on these results, we conclude that the GH locus should be further investigated in commercial breeds to determine its suitability for use in marker-assisted selection programmes.
