Resumo: The objective of this work was to determine the kinetic parameters of the dry matter in situ degradation, crude protein and neutral detergent fiber for corn silage, elephant-grass silage, Tifton-85 grass hay and soybean meal. Three rumen canulated cattle were used, with mean liveweight of 400 kg. Feeds were weighted in naylon bags, and incubated in the rumen at once. Roughages were removed at 0, 2, 4, 8, 16, 24, 48 and 72 hours, and soybean meal at 0, 2, 4, 8, 16, 24 and 48 hours after incubation. Residues in the bags were analyzed for dry matter, crude protein and neutral detergent fiber. Dry matter and crude protein of soybean meal presented highly degradable potential, as well as crude protein of corn silage. Tifton-85 grass hay presented high indigestible neutral detergent fiber fraction and therefore, low potential dry matter degradation. Amount of the neutral detergent fiber and its kinetic characteristic has a marked effect on digestion of feeds.

Foram utilizados três bovinos adultos, fistulados no rúmen, com peso vivo médio de 400 kg. Os alimentos foram pesados em sacos de náilon, incubados todos de uma vez e retirados nos tempos 0, 2, 4, 8, 16, 24, 48 e 72 horas, após a incubação dos volumosos, e 0, 2, 4, 8, 16, 24 e 48 horas, após incubação do farelo de soja. Os resíduos dos sacos foram analisados quanto ao conteúdo de matéria seca, proteína bruta e fibra em detergente neutro. A matéria seca e a proteína bruta do farelo de soja apresentaram potencial de degradação elevado, assim como a proteína bruta da silagem de milho. Destacou-se a elevada fração não-degradável da fibra em detergente neutro do feno de capim-Tifton 85 e, portanto, sua baixa degradabilidade potencial da matéria seca. O teor de fibra em detergente neutro e suas características cinéticas exercem acentuado efeito sobre a digestão dos alimentos.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCabral, Luciano da SilvaValadares Filho, Sebastião de CamposZervoudakis, Joanis Tilemahosde Souza, Alexandre LimaDetmann, Edenio2005-08-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/7025Pesquisa Agropecuaria Brasileira; v.40, n.8, ago. 2005; 777-781Pesquisa Agropecuária Brasileira; v.40, n.8, ago. 2005; 777-7811678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/7025/4073info:eu-repo/semantics/openAccess2011-08-29T13:12:41Zoai:ojs.seer.sct.embrapa.br:article/7025Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2011-08-29T13:12:41Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
