Resumo: | Four groups totaling 36 young bulls were placed in a dry lot and individually fed a ration of 66% TDN. There were two groups of ten Nellore bulls (Nellore I and Nellore II) and two groups, one of ten one-quarter Marchigiana-Nellore and one of six one-half Marchigiana-Nellore bulls (crossbred I and crossbred II, respectively). Nellore I bulls averaged 689 days of age and the other three groups averaged 613 days of age at the start of the trial. All animals were randomly assigned to three slaughter time groups (1, 2 and 3) and were fed for 119, 152 or 175 days. The crossbred II bulls had heavier (P< .05) live weights (513.5 kg) at slaughter than the Nellore I, Nellore II and crossbred I groups (476.0, 464.5 and 479.0 kg respectively). Consequently, crossbred II bulls showed heavier (P< .05) hot and chilled carcass weights than the other groups. Also the crossbred II bulls had less (P< .05) 12th rib fat cover (3.5 mm) with Nellore II bulls having lhe thicker 12th rib fat cover (6.1 mm) and Nellore I and crossbred I groups being intermediate (4.7 and 4.6 mm respectively). Loin eye area was larger (P < .05) for crossbred II (79.65 cm2) than for Nellore I, Nellore II and crossbred I groups (70.39, 68.57 and 65.93 cm2respectively). A marked advantage was shown for the crossbred II group from the standpoint of producing greater quantities of lean meat without excess waste fat. This group had higher (P< .05) proportion of edible portion from the special hindquarter (33.65%), higher (P< .05) proportion of total edible portion (76.30%) and lesser amounts of trimmable fat (6.96%). |

O grupo de cruzados II apresentou maior (P< .05) peso vivo (513.5 kg) ao abate do que o nelore I, nobre II e cruzado I (476.0, 464.5 e 479.0 kg, respectivamente). Como consequência, o grupo de cruzados II apresentou maiores pesos de carcaça quente e resfriada do que os outros grupos. Também o grupo de cruzados II apresentou a mais fina (P< .05) espessura de gordura (3.5 mm), enquanto o grupo nelore II apresentou a camada mais espessa de gordura (6.1 mm), ficando intermediários o nelore I e cruzado I (4.7 e 4.6 mm respectivamente). A área do olho-de-lombo foi significativamente maior para o grupo cruzado II (79.65 cm2) do que para nelore I. nelore II e cruzado I (7039,68.57 e 65.93 cm2, respectivamente). O grupo de cruzado II também apresentou vantagem do ponto de vista de produção de maiores quantidades de carne magra, sem a produção excessiva e desnecessária de gordura, além de maior percentagem da porção comestível do traseiro especial (33.65%), maior porcentagem da porção comestível total (76.30%) e menor quantidade de gordura aparada (6.96%).Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraLuchiari Filho, AlbinoAllen, Dell M.2014-04-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/14377Pesquisa Agropecuaria Brasileira; v.22, n.5, maio 1987; 527-534Pesquisa Agropecuária Brasileira; v.22, n.5, maio 1987; 527-5341678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/14377/8282info:eu-repo/semantics/openAccess2014-10-03T18:57:18Zoai:ojs.seer.sct.embrapa.br:article/14377Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-10-03T18:57:18Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
