Resumo: Carcass quantitative characteristics of 68 Braford steers previously submitted to two weaning ages: 91 days, early weaning (EW); 160 days, conventional weaning (CW), classified at slaughter in three live weight groups: light (? 350 kg), medium (351 a 370 kg) and heavy (? 371 kg), were evaluated. Steers were finished on summer pasture (Pennisetum americanum) and slaughtered at 16 months of age. No significant differences were observed between weaning ages for final weight (EW = 360.0 kg; CW = 359.2 kg), hot dressing percentage (EW = 53.76%; CW = 53.84%) and cold dressing percentage (EW = 52.45%; CW = 52.54%), hot carcass weight (EW = 193.0 kg; CW = 193.2 kg) and cold carcass weight (EW = 188.6 kg; CW = 188.5 kg).  Steers were also similars in carcass conformation, hindquarter and forequarter percentages and others measures of carcass development. The average slaughter weight of steers classified as light, medium and heavy was 338.7, 358.6 e 381.6 kg, respectively. Heavier steers produced carcasses with dressing percentage of 52.55% and subcutaneous fat thickness of 4.54 mm, similar to medium (52.65 and 4.39 mm, respectively) and light steers (52.93% and 3.99 mm, respectively). Weight increase did not affect the hindquarter and forequarter percentages, but cushion thickness was significantly increased when the weight increased from 338.7 to 381.6 kg. It can be concluded that early weaning doesn’t alters the weight and finishing of steers carcasses.KEYWORDS: Carcass weight, conformation, carcass dressing, early weaning, subcutaneous fat

Terminados em pastagem cultivada de verão (Pennisetum americanum) e abatidos aos dezesseis meses de idade, os novilhos foram classificados ao abate em três grupos de peso: leves (? 350 kg), médios (351 a 370 kg) e pesados (? 371 kg). Não houve diferença significativa entre as idades de desmame no peso de abate (DP = 360,0 kg; DC = 359,2 kg), rendimento de carcaça quente (DP = 53,76%; DC = 53,84%), rendimento de carcaça fria (DP = 52,45%; DC = 52,54%), peso de carcaça quente (DP = 193,0 kg; DC = 193,2 kg) e peso de carcaça fria (DP = 188,6 kg; DC = 188,5 kg). Os resultados foram também similares em conformação de carcaça, percentagem dos quartos traseiro e dianteiro e outras variáveis de desenvolvimento da carcaça. Os pesos médios de abate foram 338,7; 358,6 e 381,6 kg, respectivamente, para novilhos leves, médios e pesados. Os novilhos pesados produziram carcaças com rendimento (52,55%) e espessura de gordura subcutânea (4,54 mm) similares aos dos médios (52,65% e 4,39 mm, respectivamente) e leves (52,93% e 3,99 mm, respectivamente). O aumento dos pesos de abate não alterou os percentuais dos cortes traseiro e dianteiro, mas a espessura de coxão teve aumento significativo quando o peso médio passou de 338,7 para 381,6 kg. Conclui-se que animais desmamados aos 91 dias de idade apresentam carcaças com peso e acabamento similares aos desmamados aos 160 dias.PALAVRAS-CHAVES: Desmame precoce, gordura de cobertura, conformação, peso de carcaça, rendimento de carcaçaUniversidade Federal de Goiás2011-03-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionResearchAvaliado por paresPesquisa científicaapplication/pdftext/htmlapplication/pdfhttps://revistas.ufg.br/vet/article/view/1064210.5216/cab.v12i1.10642Brazilian Animal Science/ Ciência Animal Brasileira; Vol. 12 No. 1 (2011); 90 - 100Ciência Animal Brasileira / Brazilian Animal Science; v. 12 n. 1 (2011); 90 - 1001809-68911518-2797reponame:Ciência animal brasileira (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/vet/article/view/10642/8772https://revistas.ufg.br/vet/article/view/10642/8902https://revistas.ufg.br/vet/article/view/10642/10270Vaz, Ricardo ZambardaLobato, Jose Fernando PivaVaz, Fabiano NunesRestle, JoãoPascoal, Leonir Luizinfo:eu-repo/semantics/openAccess2011-04-22T14:19:41Zoai:ojs.revistas.ufg.br:article/10642Revistahttps://revistas.ufg.br/vetPUBhttps://revistas.ufg.br/vet/oai||revistacab@gmail.com1809-68911518-2797opendoar:2024-05-21T19:55:45.001815Ciência animal brasileira (Online) - Universidade Federal de Goiás (UFG)true
