Resumo: | A research trial was carried out at São Manuel, SP, Brazil, in order to identify the problems associated with the ensilage of tropical legumes. The species studied were: Centrosema pubescens, Galactia striata, Phaseolus atropurpureus (cv. Siratro) and Glycine wightii. Samples were taken at 56, 90 and 124 days of vegetative growth for the analysis of dry matter, soluble carbohydrate and buffering capacity to hydrochloric acid. The dry matter content of Phaseolus atropurpureus was considered to be very low, where as the other species presented over 30% dry matter only when the plants had 124 days of vegetative growth. All the species showed a very low soluble carbohydrate content and so, it was proposed that it would be necessary to include an additive for estimulation of the lactic fermentation. The buffering capacity was very high for the species studied and this fact could be aserious problem for the ensilage. |

As leguminosas estudadas foram: Centrosema pubescens, Galactia striata, Phaseolus atropurpureus ( cultivar Siratro) e Glycine wightii. Foram efetuados cortes aos 56, 90 e 124 dias de crescimento vegetativo, avaliando-se os teores de matéria seca e de carboidratos solúveis e o poder tampão ao ácido clorídrico. O siratro apresentou teores excessivos de umidade em todos os cortes; as outras espécies apresentaram teores de matéria seca adequados para ensilagem somente no último corte, com exceção da soja perene, que já no segundo corte se aproximou de 30%. O teor de carboidratos solúveis das espécies estudadas, nas três épocas, foi muito baixo e insuficiente para proporcionar uma boa fermentação láctica, ficando evidente a necessidade de aditivos ricos em açúcares para a ensilagem. O poder tampão determinado em todas as espécies estudadas foi elevado, denotando a resistência que o meio deve oferecer à queda do pH nas leguminosas tropicais ensiladas. Concluiu-se que: as quatro leguminosas estudadas não apresentaram características favoráveis para serem conservadas na forma de silagem; entretanto, se ensiladas quando novas com aditivos ricos em açúcar e com pré-murchamento da forragem, provavelmente darão origem a silagens de boa qualidade.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraTosi, HugoFaria, Vidal Pedroso deSilveira, Antônio CarlosPereira, Ricardo Luz2014-04-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/17069Pesquisa Agropecuaria Brasileira; v.10, n.4, 1975: Série Zootecnia; 19-22Pesquisa Agropecuária Brasileira; v.10, n.4, 1975: Série Zootecnia; 19-221678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/17069/11392info:eu-repo/semantics/openAccess2014-04-15T19:01:47Zoai:ojs.seer.sct.embrapa.br:article/17069Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-15T19:01:47Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
