Resumo: | The effect of termination of steers in a feedlot using the total substitution of soybean meal by slow-release or agriculture urea on the non-carcass components was evaluated. Twenty-seven purebred and Charolais × Nellore castrated crossbred steers (mean age 20 months, mean initial weight 293 kg) were allocated to received concentrates containing slow degradation urea, soybean meal, or agricultural urea. The experimental design was in randomized blocks (breed predominance), with three treatments and nine replicates, with the animal being the experimental unit. Diets did not lead to significant differences in empty body weight (EBW). The similarity between treatments was also verified in relation to EBW/slaughter weight, with mean values of 0.87 for treatments containing urea and 0.88 for soybean meal treatment. The gastrointestinal contents, both in absolute weight and in relation to EBW, were similar between the rations evaluated, with mean values of 54.33 kg and 13.52%, respectively. Steers fed with slow-release urea had a 32.8% higher weight of omasum relative to 100 kg of EBW (P < 0.05) compared to the animals fed with soybean meal. |

Foram utilizados 27 bovinos machos castrados, puros e cruzas Charolês x Nelore, com idade e peso médio inicial de 20 meses e 293 kg respectivamente, distribuídos em três tratamentos: Ureia Protegida – concentrado contendo ureia de degradação lenta; Farelo de Soja – concentrado contendo farelo de soja; Ureia Agrícola – concentrado contendo ureia agrícola. O delineamento experimental utilizado foi de blocos ao acaso (predominância racial), com três tratamentos e nove repetições, sendo o animal a unidade experimental. As dietas não proporcionaram diferenças significativas no peso de corpo vazio (PCV). Semelhança entre os tratamentos também foi verificada na relação peso de corpo vazio/peso de abate, apresentando valores médios de 0,87 para os tratamentos que continham ureias e 0,88 para o tratamento farelo de soja. O conteúdo gastrintestinal tanto em peso absoluto quanto em relação ao peso de corpo vazio apresentou similaridade entre as rações avaliadas, com valores médios de 54,33 kg e 13,52%, respectivamente. Os novilhos que receberam ureia protegida apresentaram maior peso de omaso relativo a 100 kg de PCV (P < 0,05) em relação aos animais alimentados com farelo de soja, com superioridade de 32,8%.UEL2018-11-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa Empírica de Campoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/3216410.5433/1679-0359.2018v39n6p2761Semina: Ciências Agrárias; Vol. 39 No. 6 (2018); 2761-2770Semina: Ciências Agrárias; v. 39 n. 6 (2018); 2761-27701679-03591676-546Xreponame:Semina.
