Resumo: The objective of this experiment was to compare the carcass characteristics of males weaned at two ages: 72 (T72) and 210 days (T210). Thirty-six 5/8 Hereford 3/8 Nellore calves, not castrated, finished in feedlot and slaughtered at 14 months of age, were used. No significant differences were observed between treatments for final weight (T72=424 kg and T210=406 kg), dressing percentage (T72=54.7% and T210=54.4%), hot carcass weight (T72=232 kg and T210=221 kg) and cold carcass weight (T72=224 kg and T210=214 kg). T72 carcasses showed better conformation (11.8 points vs 11.3 points) and higher sidecut percentage than T210, both having similar sawcut and hindquarter percentages. No significant differences were observed for carcass, leg and arm length, arm perimeter, cushion thickness and subcutaneous fat thickness (T72=4.6 mm and T210=4.2 mm). Results demonstrate that calves weaned at 72 days of age showed similar carcasses than calves weaned at 210 days, with adequate weight and fat thickness for slaughter.

Utilizaram-se 36 terneiros 5/8 Hereford e 3/8 Nelore, não castrados, os quais foram terminados em confinamento e abatidos aos 14 meses de idade. Não houve diferença significativa quanto ao peso de fazenda (T72=424 kg e T210=406 kg), rendimento de carcaça quente (T72=54,7% e T210=54,4%), peso de carcaça quente (T72=232 kg e T210=221 kg) e fria (T72=224 kg e T210=214 kg) entre os dois grupos. Os animais desmamados aos 72 dias apresentaram carcaça com conformação ligeiramente superior (11,8 pontos vs. 11,3 pontos) e maior percentagem de costilhar em relação aos novilhos desmamados aos 210 dias, cujos cortes dianteiro e traseiro não diferiram significativamente. Não houve diferença significativa entre as variáveis comprimento de carcaça, comprimento de perna, comprimento de braço, perímetro de braço e espessura de coxão. A espessura de gordura de cobertura não diferiu significativamente entre os dois grupos de carcaça, sendo 4,6 mm e 4,2 mm, respectivamente para T72 e T210 dias. Os resultados mostraram que animais desmamados aos 72 dias de idade apresentam carcaça comparável aos desmamados com 210 dias, com peso e acabamento dentro dos limites exigidos pelos frigoríficos.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraRestle, JoãoVaz, Fabiano NunesBrondani, Ivan LuizGonçalves, Jorge MachadoAndreatta, Evelise1999-11-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/5534Pesquisa Agropecuaria Brasileira; v.34, n.11, nov. 1999; 2137-2144Pesquisa Agropecuária Brasileira; v.34, n.11, nov. 1999; 2137-21441678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/5534/2725info:eu-repo/semantics/openAccess2010-07-08T17:20:08Zoai:ojs.seer.sct.embrapa.br:article/5534Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2010-07-08T17:20:08Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
