Resumo: | The objective of this work was to evaluate the effect of the partial replacement of corn by alternative energy sources in concentrate supplements for beef cattle kept on Urochloa brizantha cultivar Marandu pasture, during the rainy season, on feed intake and total apparent digestibility. Five Nellore cattle with initial average body weight of 367.8±4.31 kg were used. The experimental design was a 5x5 Latin square, with five animals and five treatments. The following were evaluated: isoproteic concentrate supplements, at 30% crude protein, formulated with corn, millet, and sorghum grains, and soybean hulls; and a mineral supplement (control). No significant differences were observed in total dry matter (DM) and organic matter (OM) intake between the animals fed mineral supplementation and those receiving concentrate supplementation; however, the latter showed the lowest (12.28%) pasture DM intake. Concentrate supplementation increased the coefficient of total apparent digestibility of DM, OM, crude protein, and of non‑fiber carbohydrates that were not affected by the energy sources. Millet and sorghum grains, and soybean hulls can be used to partially replace corn in the formulation of concentrate supplements without affecting intake and digestibility of dietary nutrients. |

Foram utilizados cinco bovinos Nelore com peso médio corporal inicial de 367,8±4,31 kg. Utilizou-se o delineamento experimental quadrado latino 5x5, com cinco animais e cinco tratamentos. Foram avaliados: suplementos concentrados isoproteicos, com 30% de proteína bruta, formulados à base de grãos de milho, de milheto e de sorgo, e casca de soja; e um suplemento mineral (controle). Não foram observadas diferenças significativas no consumo de matéria seca (MS) total e de matéria orgânica (MO) entre os animais que receberam suplementação mineral e os que receberam suplementação concentrada; no entanto, estes últimos apresentaram menor (12,28%) consumo de MS de pasto. A suplementação concentrada aumentou o coeficiente de digestibilidade aparente total da MS, da MO, da proteína bruta e dos carboidratos não fibrosos que não foram influenciados pelas fontes de energia. Os grãos de milheto e de sorgo e a casca de soja podem ser utilizados em substituição parcial ao milho, na formulação de suplementos concentrados, sem prejudicar o consumo e a digestibilidade dos nutrientes da dieta.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraFAPEMATCardoso, Adriano BorgesMoraes, Eduardo Henrique Bevitori Kling deOliveira, André SoaresZervoudakis, Joanis TilemahosCabral, Luciano da SilvaSilva, Pedro Ivo José Lopes da Rosa eSocreppa, Leandro Munhoz2013-12-02info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/14564Pesquisa Agropecuaria Brasileira; v.48, n.9, set. 2013; 1295-1302Pesquisa Agropecuária Brasileira; v.48, n.9, set. 2013; 1295-13021678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/14564/12427https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/14564/9752info:eu-repo/semantics/openAccess2013-12-04T12:06:14Zoai:ojs.seer.sct.embrapa.br:article/14564Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2013-12-04T12:06:14Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
