Resumo: The objective of this work was to study the carcass characteristics of Aberdeen Angus castrated steers, finished by 112 days in feedlot, with sugar cane + concentrate, or in cultivated pasture of ryegrass (Lolium multiflorum). Confined animals were fed with isonitrogeneous diets (13.2% of crude protein) containing, on dry matter, 72.3% of sugar cane and 27.7% of concentrate. Twelve steers, with initial weight of 320 kg and 20 months of age, were used. No difference (P> .05) was observed for slaughter and hot carcass weight that were, respectively, 396 and 202 for steers fed with cultivated pasture and 394 and 201, in the same order, for steers fed with sugar cane. There wasn’t difference (P> .05) between treatments for carcass hot dressing and commercial cuts percentages, carcass length, conformation, fat thickness and longissimus dorsi area. Has significative correlation in two treatments for carcass weight and cushion thickness, conformation and longissimus dorsi area. Steers finished on cultivated pasture the conformation was correlated with all variables.KEY WORDS: Bos taurus, dressing percentage, forage quality, Lolium multiflorum, sugar cane.

Alimentaram-se os animais confinados com dietas isonitrogenadas (13,2% de proteína bruta) contendo, na matéria seca, 72,3% de cana-de-açúcar e 27,7% de concentrado. Utilizaram-se doze novilhos, com peso inicial de 320 kg e idade de 20 meses, arranjados num delineamento inteiramente casualizado. Não houve diferença (P>0,05) nos pesos de fazenda e de carcaça quente que foram, respectivamente, de 396 e 202 kg nos novilhos alimentados com pastagem cultivada e de 394 e 201 kg, citados na mesma ordem, para os novilhos alimentados com cana-de-açúcar. Não houve diferença (P>0,05) entre tratamentos para as variáveis rendimento de carcaça quente, percentagem dos cortes comerciais da carcaça, comprimento e conformação de carcaça, espessura de gordura de cobertura e área de longissimus dorsi. Houve correlação significativa nos dois grupos de novilhos entre o peso de carcaça e as variáveis espessura de coxão, conformação e área de longissimus dorsi. Os novilhos terminados em pastagem tiveram a conformação de carcaça correlacionada com todas as outras variáveis medidas.Universidade Federal de Goiás2008-10-14info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado por paresPesquisaapplication/pdfhttps://revistas.ufg.br/vet/article/view/93010.5216/cab.v9i3.930Brazilian Animal Science/ Ciência Animal Brasileira; Vol. 9 No. 3 (2008); 590-597Ciência Animal Brasileira / Brazilian Animal Science; v. 9 n. 3 (2008); 590-5971809-68911518-2797reponame:Ciência animal brasileira (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/vet/article/view/930/4125Vaz, Fabiano NunesRestle, JoãoMetz, Patrícia Alessandra MeneguzziMoletta, José Luizinfo:eu-repo/semantics/openAccess2008-10-15T19:36:43Zoai:ojs.revistas.ufg.br:article/930Revistahttps://revistas.ufg.br/vetPUBhttps://revistas.ufg.br/vet/oai||revistacab@gmail.com1809-68911518-2797opendoar:2008-10-15T19:36:43Ciência animal brasileira (Online) - Universidade Federal de Goiás (UFG)false
