Resumo: The objective of the experiment was to evaluate the feedlot performance, average daily gain, feed consumption and feed conversion, of steers finished with different body weights. Eighteen Charolais steers, 30 months old, and initial weight of 297.0 kg±11.5 kg were used. The steers were slaughtered when the group average live weight reached 421.0 kg±45.4 kg (T1), 461.0 kg±29.1 kg (T2) or 495.0 kg±17.8 kg (T3). The steers were fed with a 12% crude protein diet, containing 57% of concentrate and 43% of green chopped sugar cane. A complete randomized design was used. Feed consumption was similar for the three treatments. However, feed consumption per 100 kg of live weight decreased as slaughter weight increased. Average daily gain of the steers was 1.12 kg±.05 kg, 1.17 kg±.12 kg and 1.05 kg±.09 kg, for T1, T2 and T3, respectively. Feed conversion was similar (P>.1696) for the three treatments. Subcutaneous fat was 2.4 mm±1.0 mm, 2.6 mm±1.8 mm and 5.4 mm±1.0 mm (P<.0022), respectively. The period for steers to reach the final weight was 110, 145 and 184 days, respectively.

Ao início do experimento os novilhos apresentavam 30 meses de idade e o peso médio era de 297,0 kg±11,5 kg. Os animais receberam uma dieta contendo 12% de proteína bruta, composta de cana-de-açúcar (43%) e concentrado (57%). O delineamento experimental utilizado foi o inteiramente casualizado com duas repetições por tratamento, sendo cada repetição formada por um lote de três animais. O consumo médio diário de matéria seca foi similar nos três tratamentos. Entretanto, o consumo de matéria seca por 100 kg de peso vivo decresceu à medida que os novilhos atingiam peso final mais elevado. O ganho de peso médio diário dos novilhos foi, respectivamente, de 1,12 kg±0,05 kg; 1,17 kg±0,12 kg e 1,05 kg±0,09 kg (P>0,1112). Não houve diferença significativa (P>0,1696) quanto à conversão alimentar entre os novilhos dos diferentes tratamentos. A gordura de cobertura nas carcaças foi de 2,4 mm±1,0 mm; 2,6 mm±1,8 mm e 5,4 mm±1,0 mm (P<0,0022) para T1, T2 e T3, respectivamente. O período utilizado para os novilhos atingirem o peso final foi de 110, 145 e 184 dias, na mesma ordem.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraRestle, JoãoKeplin, Luis Antonio da SilveiraVaz, Fabiano Nunes1997-08-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/4724Pesquisa Agropecuaria Brasileira; v.32, n.8, ago. 1997; 857-860Pesquisa Agropecuária Brasileira; v.32, n.8, ago. 1997; 857-8601678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/4724/7324info:eu-repo/semantics/openAccess2015-03-12T16:26:31Zoai:ojs.seer.sct.embrapa.br:article/4724Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2015-03-12T16:26:31Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
