Conteúdo: | Candidate gene strategy has been proposed to direct the search for quantitative trait loci, and polymorphisms at these loci have been associated with several production traits in bovine. A total of 211 animals resulting from crosses between Nelore females with sires from either Aberdeen Angus, Canchim and Simmental breeds were analyzed for restriction fragment length polymorphisms (RFLPs) in the ?-casein, ?-lactoglobulin (LGB) and growth hormone GH genes. Average daily gain from birth to weaning (GBW) and from weaning to yearling (GWY) were analyzed by a statistical model comprising RFLP genotypes and their interaction effects. Significant effects (p < 0.05) of growth hormone (GH) and of the interaction ?-lactoglobulin?×?GH were verified for the GWY. Animals with LL genotypes for GH had higher GBW than LV animals but lower GWY (p < 0.05).
