Candidate genes for growth traits in beef cattle crosses <i>Bos taurus</i> × <i>Bos indicus</i>
説明
<jats:title>Summary</jats:title><jats:p>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 <jats:italic>κ</jats:italic>‐casein, <jats:italic>β</jats:italic>‐lactoglobulin (LGB) and growth hormone <jats:italic>GH</jats:italic> 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 (<jats:italic>GH</jats:italic>) and of the interaction <jats:italic>β</jats:italic>‐lactoglobulin × <jats:italic>GH</jats:italic> were verified for the GWY. Animals with LL genotypes for <jats:italic>GH</jats:italic> had higher GBW than LV animals but lower GWY (p < 0.05).</jats:p>
