Resumo: Com (Zea mays L.) was ensiled in plastic bags at five maturity stages and different moisture contents with the objective of determining the number of Clostridium spores present. Chemical analyses were made in the silage material to determine the protein content, dry matter, moisture, pH and NH3/N. According to the results obtained, it was concluded that the corn presented an optimum level of dry matter (35%) for ensilage between 15 and 16 weeks after planting, in the stage of farinaceous grains. The high acidity of the ensiled mass (pH 3,96 - 4,10) was responsible for the inhibition of the germination of Clostridium sp. spores. The number of viable spores in the ensiled mass decreased with the increase of the dry matter content with the correlation coefficient (r = -0,7949**) statistically significant.

Paralelamente, foram determinados os parâmetros químicos de avaliação das silagens: teor de proteínas, matéria seca, umidade, pH e NH3/N. Pelos resultados obtidos concluiu-se que o milho apresentou teor ótimo de matéria seca para ensilagem (35%) entre 15 e 16 semanas após o plantio, no estádio de grãos farináceos. A elevada acidez da massa ensilada (pH = 3,96 - 4,10) foi responsável pela inibição da germinação dos esporos de Clostridium sp. presentes. O número de esporos viáveis na massa ensilada diminuiu à medida que aumentou o teor de matéria seca, com coeficiente de correlação (r = - 0,7949**) estatisticamente significativo.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraTosi, HugoIturrino, Ruben Ruben SchockenRavazzi, José Paulo2014-04-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/16012Pesquisa Agropecuaria Brasileira; v.17, n.8, ago. 1982; 1133-1136Pesquisa Agropecuária Brasileira; v.17, n.8, ago. 1982; 1133-11361678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/16012/10155info:eu-repo/semantics/openAccess2014-04-16T16:22:09Zoai:ojs.seer.sct.embrapa.br:article/16012Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-16T16:22:09Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
