Resumo: | The intake, the apparent digestibility and the nutritive value of elephant grass (Pennisetum purpureum Schum.) silages prepared with the addition of 0, 8, 16 and 24% of ground ear corn with husks, wheat bran and saccharin, dry weight of additive/wet weight of green chop upon the silage were evaluated. A randomized block design with three replications, in a factorial arrangement (3 additives x 4 levels) was used. As experimental silos, 200-liter plastic vessels were used. Sheep weighing approximately 50 kg, kept in individual cages, receiving water and mineral mixture ad libitum, were used to measure the intake and apparent digestibility of silages. There was a ten-day period of adaptation to the experiment conditions. The voluntary intake of the silages was determined by the mean of the intake observed in the last three days of a ten-day period. The fecal collection period lasted for seven days. In this period the animals were fed 80% of the observed intake obtained in the previous phase. The dry matter intake increased as the levels of the additives in the silages were increased. The digestibility of the wall cell components decreased as the rates of the additives in the ensilage process increased. The silages prepared with wheat bran or ground ear corn with husks showed higher nutritive value than the ones with saccharin. |

O delineamento utilizado foi de blocos casualizados com três repetições, em esquema fatorial 3 (aditivos) x 4 (níveis). Foram utilizadas como silos experimentais barricas de plástico de 200 litros. O teste de consumo e digestibilidade foi efetuado com ovinos machos castrados, com peso ao redor de 50 kg. Os animais foram abrigados em baias individuais, com água e sal mineral à vontade. Houve um período de dez dias para adaptação dos animais às condições experimentais. O consumo voluntário das silagens foi determinado pela média dos três últimos dias de um período de dez. O período de coleta se desenvolveu por sete dias. Nesse período, os animais foram alimentados com 80% do consumo voluntário. A ingestão de matéria seca aumentou à medida que foi elevado o nível dos aditivos na ensilagem. Houve redução na digestibilidade dos componentes da parede celular com o aumento da participação dos aditivos na ensilagem. As silagens preparadas com farelo de trigo ou rolão de milho mostraram maior valor nutritivo.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária Brasileirade Andrade, João BatistaLavezzo, Wagner1998-12-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/5026Pesquisa Agropecuaria Brasileira; v.33, n.12, dez. 1998; 2015-2023Pesquisa Agropecuária Brasileira; v.33, n.12, dez. 1998; 2015-20231678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/5026/7183info:eu-repo/semantics/openAccess2014-12-17T15:27:03Zoai:ojs.seer.sct.embrapa.br:article/5026Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-12-17T15:27:03Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
