Resumo: | In five indoor digestion trials, Nellore steers (140-230 kg live-weight) were fed with Brachiaria decumbens (BD) and native pasture (NP), cut at different maturity stages and made into hay: in a sixth experiment poor quality native hay was given with and without 0.5 kg of cottonseed meal (CSM) per steer daily. Digestibility and intake of BD were for the most part significantly greater than NP and the differences increased with plant maturity. Supplementing poor quality native hay with 0.5 kg CSM per steer daily resulted in a significant increase in total feed intake. Significant correlation coefficients were found between digestibility of feed dry and organic matter and nitrogen content of feed and faeces; r values, relating digestibility to intake, ranged from 0.40 (NP) to 0.77 (BD) and for faecal nitrogen (FN) and digestible organic matter (DOM) were 0.71 or 0.79 (BD, with and without dry season herbage) and 0.66 for NP. Approximately similar figures were calculted for FN and organic matter intake. Within BD, r values of 0.98 (each case) were found between percentage of leaves and both digestibility and intake of organic matter. |

Os dados de digestibilidade e consumo de BD foram, na maioria das vezes, significativamente superiores aos obtidos com PN, e as diferenças aumentaram com a maturidade das plantas. A suplementação de feno de PN de baixa qualidade com 0,5 kg de farelo de sementes de algodão/novilho/ dia resultou em aumento significativo no total de alimento consumido. Coeficientes de correlação significativos foram encontrados entre as digestibilidades de matéria seca e da matéria orgânica e os conteúdos de nitrogênio dos alimentos e das fezes; os valores de r, relacionando digestibilidade e consumo, variaram de 0,40 (PN) a 0,77 (BD) e, para nitrogênio fecal (NF) e matéria orgânica digestível (MOD), foram de 0,71 e 0,79 (BD, com e sem os dados da estação seca) e 0,66 para PN. Resultados similares foram obtidos quando se relacionou NF e consumo de matéria orgânica. Para BD, valores de r de 0,98 (para ambos os casos) foram encontrados quando a percentagem de folhas foi relacionada à digestibilidade e ao consumo de matéria orgânica.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraEuclides, Valéria P.B.Silva, José Marques da2014-04-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/16387Pesquisa Agropecuaria Brasileira; v.17, n.11, nov. 1982; 1655-1670Pesquisa Agropecuária Brasileira; v.17, n.11, nov. 1982; 1655-16701678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/16387/10626info:eu-repo/semantics/openAccess2014-04-15T19:48:25Zoai:ojs.seer.sct.embrapa.br:article/16387Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-15T19:48:25Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
