ABSTRACT
The association between G316A growth hormone polymorphism and quantitative traits was investigated in an F2 population of pigs. Association analyses were performed using a statistical model that included genotype, sex, batch and sex by genotype interaction as fixed effects and sire as random effect. The polymorphism was associated with the number of right teats (p = 0.03), heart weight (p = 0.04), lung weight (p = 0.05), carcass length determined by the Brazilian carcass classification method (p = 0.04), picnic shoulder weight (p = 0.07), jowl weight (p = 0.01), pH 24 h after slaughtering (p = 0.03) and drip loss (p = 0.01). Interaction between genotype and sex was observed for six performance traits. The additive effect was significant (p < 0.10) for heart weight, jowl weight and pH 24 h after slaughtering. The effect of dominance was significant (p < 0.05) for number of right teats, heart weight, carcass length, picnic shoulder weight and pH 24 h after slaughtering. This study shows that the growth hormone gene is a potential candidate for investigating the phenotypic variation of quantitative traits in pigs, and suggests its possible application in breeding programs.
