Resumo: The objective of this work was to evaluate the chemical composition and aerobic stability of corn grain silage, added with crude soybean, sunflower or urea. The following treatments, arranged in a completely randomized design, with four replications, were evaluated: corn grain; corn grain plus soybean grain; corn grain plus sunflower grain; and corn grain plus urea. Plastic barrels with 200 kg of capacity were used as experimental silos and kept closed for nine months. Chemical composition, dry matter and crude protein ruminal degradability, starch ruminal disappearance, and the aerobic stability of silages were evaluated. The addition of soybean, sunflower or urea on silages influenced the effective degradability of dry matter and crude protein, and the chemical composition, especially in relation to crude protein and ether extract contents. The addition of 20% soybean, sunflower or urea (1%) in corn grain silage improves chemical composition, but decreases the effective degradability of dry matter and crude protein. Urea addition to moist corn grain silage reduces losses on dry matter and improves the aerobic stability.

Em delineamento inteiramente casualizado, com quatro repetições, foram avaliados os tratamentos: grãos de milho; grãos de milho mais grãos de soja; grãos de milho mais grãos de girassol; e grãos de milho mais uréia. Foram utilizados, como silos experimentais, tonéis de plástico com capacidade para 200 kg, que permaneceram vedados por nove meses. Avaliaram-se: a composição química, a degradabilidade ruminal da matéria seca e da proteína bruta, o desaparecimento do amido no rúmen e a estabilidade aeróbia das silagens. Todos os tratamentos tiveram efeito sobre a degradabilidade efetiva da matéria seca e da proteína bruta, e também sobre a composição química das silagens, especialmente nos teores de proteína bruta e extrato etéreo. A adição de 20% de grãos de soja, de girassol ou uréia (1%), na silagem de grãos de milho, melhora sua composição químico-bromatológica, porém reduz a degradabilidade efetiva da matéria seca e da proteína bruta. A adição de uréia à silagem de grãos úmidos de milho diminui as perdas de matéria seca e melhora a estabilidade em aerobiose.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCNPqJobim, Clóves CabreiraLombardi, LauzimeryMacedo, Francisco Assis Fonseca deBranco, Antonio Ferriani2008-10-21info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/373Pesquisa Agropecuaria Brasileira; v.43, n.5, maio 2008; 649-656Pesquisa Agropecuária Brasileira; v.43, n.5, maio 2008; 649-6561678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/373/5433info:eu-repo/semantics/openAccess2012-06-17T11:38:50Zoai:ojs.seer.sct.embrapa.br:article/373Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2012-06-17T11:38:50Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
