Resumo: | Assessment of carcass and meat characteristics of Nellore young bulls or dairy crossbred young bulls fed two levels of grass-Convert silage in the rations (400 and 100 g kg-1 of dry matter). Sixteen Nellore young bulls and 16 dual-purpose dairy young bulls (Holstein x Gir and Holstein x Guzerá) with average initial body weight of 378.8±13.8 kg were used. The experimental design was completely randomized with treatments in a 2x2 factorial arrangement. The proportion of silage and the genetic group did not change the percentage of muscle, fat and bone of the carcass. The yield of the primary commercial cuts was not altered by the level of silage. The pistol cut weight was higher in Nellore young bulls compared to dairy crossbred young bulls (125.8 vs. 119.5 kg), while the relative weight of short ribs was higher in dairy crossbreds (11.9 vs. 11.5%). Only the muscle cut of the pistol was altered by silage proportion in the rations, being higher in those with the lowest proportion of grass silage. On the other hand, only the relative weight of flat, rump cap and edible lean trims were altered by genetic group, which were higher in Nellore young bulls. Among the characteristics of the meat, only marbling was significantly changed, being higher in dairy crossbreds fed rations with a lower grass-silage proportion. The genetic group did not alter the other meat characteristics. Nellore young bulls produce carcasses with higher yield of valuable meat cuts in relation to dairy crossbred young bulls. |

Foram utilizados 16 tourinhos da raça Nelore e 16 tourinhos mestiços de origem leiteira, com peso médio inicial de 378,8±13,8 kg. O delineamento experimental foi o inteiramente casualizado com os tratamentos em arranjo fatorial 2x2. A proporção de silagem e o grupo genético dos animais não alteraram a percentagem de músculo, gordura e osso da carcaça. O rendimento dos cortes comerciais primários não foi alterado pelo nível de silagem. O peso do traseiro especial foi superior nos tourinhos Nelore em relação aos mestiços leiteiros (125,8 vs 119,5 kg), enquanto o peso relativo da ponta de agulha foi superior nos mestiços leiteiros (11,9 vs 11,5%). Somente o corte denominado “músculo” do traseiro especial foi alterado pela proporção de silagem nas rações, sendo superior naquelas com menor proporção de volumoso. Por outro lado, apenas o peso relativo do coxão duro, picanha e recortes comestíveis foram alterados pelo grupo genético, que foram superiores nos animais da raça Nelore. Dentre as características da carne, apenas o marmoreio foi alterado significativamente, sendo superior nos mestiços leiteiros que receberam rações com menor proporção de silagem. O grupo genético dos animais não alterou as demais características da carne. Tourinhos da raça Nelore produzem carcaças com maior rendimento de cortes nobres em relação aos mestiços leiteiros.UEL2017-06-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa empírica de campoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/2643310.5433/1679-0359.2017v38n3p1501Semina: Ciências Agrárias; Vol. 38 No. 3 (2017); 1501-1512Semina: Ciências Agrárias; v. 38 n. 3 (2017); 1501-15121679-03591676-546Xreponame:Semina.
