Resumo: The aim of this trial was to evaluate if non-castrated growing beef steers in feedlot systems would respond to increasing levels of metabolizable protein in the diet estimated by NRC (1996, Level I), through the addition of soybean meal in substitution of urea. Thirty-six steers (24 Nelore and 12 Canchim) with liveweight of 230 kg and 15 months of age were assigned in a completely randomized block design. Diets were formulated according to NRC (1996, Level I) in order to obtain a positive rumen degradable protein balance and sufficient metabolizable energy to ensure an average daily gain (ADG) of 1.3 kg/animal/day in all treatments, which were: urea (U), soybean meal + urea (FSU) and soybean meal (FS). Dry matter intake (DMI) was not affected by treatments (P>0.05). ADG was lower (P

Utilizaram-se vinte e quatro novilhos da raça Nelore e doze da raça Canchim, com peso vivo inicial médio de 230 kg e idade inicial média de quinze meses. O delineamento experimental adotado foi o de blocos ao acaso. Formularam-se as dietas de modo a se obter um balanço de proteína degradável no rúmen (PDR) positivo e energia metabolizável suficiente para ganho de peso diário de 1,3 kg/animal/dia em todos os tratamentos, sendo: ureia (U), farelo de soja + ureia (FSU) e farelo de soja (FS). Não se detectou diferença no consumo de matéria seca (MS) entre os tratamentos (P>0,05). O ganho de peso médio diário (GPD) no tratamento U (1,14 kg/animal/dia) foi menor (PUniversidade Federal de Goiás2009-07-02info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado por paresPesquisaapplication/pdfhttps://revistas.ufg.br/vet/article/view/658310.5216/cab.v10i2.6583Brazilian Animal Science/ Ciência Animal Brasileira; Vol. 10 No. 2 (2009); 373-378Ciência Animal Brasileira / Brazilian Animal Science; v. 10 n. 2 (2009); 373-3781809-68911518-2797reponame:Ciência animal brasileira (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/vet/article/view/6583/4827Fernandes, Juliano José de ResendePires, Alexandre VazOliveira Jr., Reinaldo Cunha deSantos, Flávio Augusto PortelaSusin, IvaneteCarvalho, Eduardo Rodrigues deinfo:eu-repo/semantics/openAccess2009-07-03T14:37:09Zoai:ojs.revistas.ufg.br:article/6583Revistahttps://revistas.ufg.br/vetPUBhttps://revistas.ufg.br/vet/oai||revistacab@gmail.com1809-68911518-2797opendoar:2024-05-21T19:55:25.086652Ciência animal brasileira (Online) - Universidade Federal de Goiás (UFG)true
