Resumo: The data for this study were collected from 246 animals born in the years 1990 and 1991. These animals were progenies of F1 cows sired by Fleckvieh, Charolais and Chianina bulls mated with Nellore cows. The main objective was to evaluate cows with different milk yield potentials with respect to efficiency of production. The results obtained allow the conclusion that there were differences (P < 0.05) among the cow genetic groups for birth weight, weaning weight and weaning efficiency measured as kilograms of calf weaning weight by kilograms of cow weight at the weaning of her calf. Sex of the calf also affected (P < 0.05) all three traits studied, with the male calves being superiors for all of them. The best efficiency at weaning was recorded for the Fleckvieh-Nellore F1 cows. There was no difference (P > 0.05) between the Chianina-Nellore and the Charolais-Nellore F1 cows.

O objetivo deste trabalho foi o de avaliar a eficiência de produção de vacas de corte com diferentes potenciais para produção de leite. Os resultados obtidos permitiram a conclusão de que houve diferenças entre os diferentes grupos genéticos de vacas (P < 0,05) quanto a pesos ao nascimento e à desmama e quanto a eficiência à desmama, medida como quilogramas de bezerros desmamados por quilograma de vaca à desmama do bezerro. Sexo de bezerro também influenciou significativamente (P < 0,05) estas três características, sendo os machos superiores às fêmeas. A maior eficiência à desmama foi obtida com vacas meios-sangues Fleckvieh-Nelore, não havendo diferença entre as meios-sangues Chianina-Nelore e Charolês-Nelore.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraFilho, Kepler Euclidesde Figueiredo, Geraldo RamosEuclides, Valéria Pacheco Batista1995-07-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/4390Pesquisa Agropecuaria Brasileira; v.30, n.7, jul. 1995; 1003-1007Pesquisa Agropecuária Brasileira; v.30, n.7, jul. 1995; 1003-10071678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/4390/1676info:eu-repo/semantics/openAccess2010-05-11T12:17:45Zoai:ojs.seer.sct.embrapa.br:article/4390Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2010-05-11T12:17:45Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
