| description | The objectives of the present study were to estimate the allele and genotype frequencies of the GH1/Alu I and POU1F1/Hinf I polymorphisms in beef cattle belonging to different genetic groups and to determine the effects of these polymorphisms on growth and carcass traits in cattle submitted to feedlot management, an intensive production model. Genotyping was performed on 384 animals, including 79 Nellore, 30 Canchim (5/8 Charolais + 3/8 Zebu), 30 Simmental x Nellore crossbred and 245 Angus x Nellore crossbred cattle. Body weight, weight gain, dressing percentage, Longissimus dorsi area and backfat thickness were fitted using the General Linear Model (GLM) procedure of the SAS program and the least square means of the genotypes were compared using the F test. The results showed significant associations between the LL genotype of the GH1/Alu I polymorphism and higher weight gain and body weight at slaughter (p < 0.05). The POU1F1/Hinf I polymorphism did not have any effect on the growth and carcass traits analyzed. |
