Resumo: A commercial bunker silo and three types of experimental silos were used for determination of chemical composition and fermentation characteristics of corn silage (27.3% DM and 8.4% CP) ensiled in two different densities (400 or 600kg of silage/m3): 1) commercial bunker silo sampled at 0, 50 and 100 cm from the top; 2) plastic silo with bulsen valve; 3) plastic bag; and 4) concrete pipe. Dry matter and CP concentration showed larger variation among different levels in the commercial silos and were intermediate in the experimental ones. This indicated that water and nutrients translocation were greater in the commercial than in the experimental silos. Experimental silos well represented the commercial ones concerning cell wall, starch, water-soluble carbohydrates and IVDDM. In commercial bunker silo, pH value was low in the middle extract and higher on the top. Silage obtained from the middle extract presented greater values of NH3-N and lactic acid concentrations, while silage obtained from deep extract had higher acetic acid concentrations. Fermentation (pH, concentration of ethanol, acetic, propionic, butyric, lactic and ammoniacal N) in the experimental silos was similar to the commercial silos. Variation in fermentation in different extracts of commercial silos was greater than in different types of experimental silos

Variation in fermentation in different extracts of commercial silos was greater than in different types of experimental silosTrês diferentes tipos de silos de laboratório, confeccionados a partir de baldes plásticos, sacos plásticos e manilhas de concreto com revestimento plástico, em dois diferentes graus de compactação (400 ou 600 kg de silagem/m3), foram comparados com o silo comercial tipo trincheira amostrado a 0, 50 e 100 cm da sua superfície. A planta de milho (27,3% de MS e 8,4% de PB) foi picada, homogeneizada e utilizada para encher quatro silos por tratamento. Depois de abertos, estes foram amostrados para análise da composição bromatológica e perfil fermentativo. Os teores de MS e PB variaram entre os diferentes extratos do silo comercial e foram intermediários nos silos laboratoriais, indicando maior translocação de água e nutrientes naquele do que nestes. Os silos laboratoriais representaram bem os comerciais, quanto aos componentes da parede celular, amido, carboidratos solúveis e DIVMS. O pH foi menor na silagem obtida no extrato médio, intermediário no profundo e maior na superfície do silo comercial. Silagens obtidas no extrato médio também apresentaram maiores teores de nitrogênio amoniacal e ácido lático, enquanto que as obtidas no extrato profundo apresentaram as concentrações mais elevadas de ácido acético. De forma geral, os silos laboratoriais representaram bem o perfil de fermentação dos silos comerciais (pH, concentração de etanol, acético, propiônico, butírico, lático e N amoniacal), já que a maior variabilidade de resposta foi observada entre os extratos do silo comercialEditora da Universidade Estadual de Maringá2008-04-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.uem.br/ojs/index.php/ActaSciAnimSci/article/view/257910.4025/actascianimsci.v24i0.2579Acta Scientiarum.
