Resumo: The present work was carried out in Goiânia - Goiás with the objectives to start in selection of bulls through weights differences between Gir and Nelore breeds. Forty-eight controlled calves were used and submitted to the same conditions of control and feeding: 50% ground snapped corn, 25% corn meal, 20% cottonseed meal and 5% alfafa hay. The experiment lasted 140 days and showed that gain wise and speed gain weights, 60% of the animals was qualified to the reproduction. It was observed that great differences exist in weights and weight gains as in as much as between breeds. The animals of the Nelore’s breed surpass those of the Gir’s breed in initial weight (198.4 versus 178.9 kg), weight gain (114.3 versus 104.9 kg), final weight (312.7 versus 283.8 kg) and adusted final weight (312.9 versus 283.2 kg) but the statistical significance was only reached for final weights. Other feeding-tests will de carried out, coppecting the imperfections mentioned here, and certainly it will produce more and better informations.

O presente trabalho foi realizado em Goiânia - Goiás e teve como objetivos iniciar a seleção de reprodutores através do "feeding-test" e verificar possíveis diferenças de ganhos em peso e pesos finais entre as raças Gir e Nelore. Foram utilizados 48 bezerros controlados e submetidos às mesmas condições de manejo e alimentação: 50% de milho desintegrado (espiga inteira), 25% de fubá de milho, 20% de farelo de algodão e 5% de feno de alfafa. O experimento durou 140 dias e demonstrou que, em termos de ganho e velocidade de ganho em peso, 50% dos animais estavam aptos para a reprodução. Observou-se que existem grandes diferenças de pesos e ganhos em peso tanto dentro quanto entre as raças. Os animais da raça Nelore superam os da raça Gir em peso inicial (198,4 x 178,9 kg), ganho em peso (114,3 x 104,9 kg), mas a significância estatística só foi atingida para os pesos finais. Outras provas deverão ser realizadas, corrigindo-se as falhas aqui apontadas, e trarão certamente melhores informações.Escola de Agronomia - Universidade Federal de Goiás2007-10-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado por paresapplication/pdfhttps://revistas.ufg.br/pat/article/view/2194Pesquisa Agropecuária Tropical [Agricultural Research in the Tropics]; v. 5, n. 1, Jan./Dec. 1975; 27-33Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics); v. 5, n. 1, jan./dez. 1975; 27-33Pesquisa Agropecuária Tropical; v. 5, n. 1, jan./dez. 1975; 27-331983-4063reponame:Pesquisa Agropecuária Tropical (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/pat/article/view/2194/2151Pato, José MagnoGalvão, Francisco Eduardoinfo:eu-repo/semantics/openAccess2020-02-26T23:48:02Zoai:ojs.revistas.ufg.br:article/2194Revistahttps://revistas.ufg.br/patPUBhttps://revistas.ufg.br/pat/oaiaseleguini.pat@gmail.com||mgoes@agro.ufg.br1983-40631517-6398opendoar:2024-05-21T19:54:57.795452Pesquisa Agropecuária Tropical (Online) - Universidade Federal de Goiás (UFG)true
