Resumo: Intake, apparent digestibility of nutrients, daily gain, feed conversion and the carcass yield in beef cattle receiving diets containing 0; 0.5; 1.0 e 1.5% of urea in total dry matter were evaluated. Twenty four crossed steers Holstein x Zebu (HxZ), castrated, with initial mean body weight of 290 kg were distributed in a completely randomized design. Sorghum silage was used as roughage adopting relation roughage:concentrate of 70:30 in dry matter basis. In order to determine the fecal excretion, indigestible acid detergent fiber was used as a marker. Intake and digestibility of nutrients were not influenced (P>0.05) by the proportions of urea in the diets. For intake and apparent digestibility of dry matter, mean values of 8.42 kg/day or 2.33% of BW and 64.52% were registered, respectively. Mean daily gain (1.05kg), feed conversion (8.07) and carcass yield (48.72%) were not influenced (P>0.05) by the proportions of urea in the diets. Levels of 1.5% of urea in dry matter of total diet can be used in the preparation of diets for finishing beef cattle (HxZ), without compromising intake and digestibility of nutrients and the animal performance as well.KEY WORDS: Carcass yield, feed conversion, feedlot, sorghum silage.

Foram utilizados 24 animais mestiços Holandês x Zebu (HxZ), castrados, com peso vivo inicial médio de 290 kg, distribuídos em um delineamento inteiramente casualizado. Utilizou-se a silagem de sorgo como volumoso numa relação volumoso:concentrado de 70:30, com base na matéria seca. Para determinação da excreção fecal, utilizou-se a fibra em detergente ácido indigestível como indicador. O consumo e a digestibilidade dos nutrientes não foram influenciados (P>0,05) pelos níveis de uréia na dieta. Para o consumo e a digestibilidade aparente da matéria seca, verificaram-se valores médios de 8,42 kg/dia ou 2,33% do PV e 64,52%, respectivamente. O ganho médio diário (1,05kg), a conversão alimentar (8,07) e o rendimento de carcaça (48,72%) também não foram influenciados (P>0,05) pelos níveis de uréia na dieta. Níveis de até 1,5% de uréia na matéria seca da dieta total podem ser utilizados nas formulações de dietas para terminação de bovinos de corte (HxZ), sem comprometimento do consumo e digestibilidade dos nutrientes, bem como do desempenho animalPALAVRAS-CHAVES: Confinamento, conversão alimentar, rendimento de carcaça, silagem de sorgo.Universidade Federal de Goiás2008-10-14info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado por paresPesquisaapplication/pdfhttps://revistas.ufg.br/vet/article/view/64310.5216/cab.v9i3.643Brazilian Animal Science/ Ciência Animal Brasileira; Vol. 9 No. 3 (2008); 552-562Ciência Animal Brasileira / Brazilian Animal Science; v. 9 n. 3 (2008); 552-5621809-68911518-2797reponame:Ciência animal brasileira (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/vet/article/view/643/4122Pereira, Odilon Gomesde Souza, Viviane GlauciaValadares Filho, Sebastião de CamposPereira, Dalton HenriqueRibeiro, Karina GuimarãesCecon, Paulo Robertoinfo:eu-repo/semantics/openAccess2008-10-15T19:36:43Zoai:ojs.revistas.ufg.br:article/643Revistahttps://revistas.ufg.br/vetPUBhttps://revistas.ufg.br/vet/oai||revistacab@gmail.com1809-68911518-2797opendoar:2024-05-21T19:54:44.261958Ciência animal brasileira (Online) - Universidade Federal de Goiás (UFG)true
