| Avaliaram-se a composição química e a digestibilidade in vitro da matéria seca (DIVMS) do bagaço de cana-de-açúcar hidrolisado com óxido de cálcio em dois períodos. As doses de óxido de cálcio aplicadas ao bagaço foram 0; 1,25; 2,5 e 3,75% (na base da MS) e os períodos de tratamento, 12 e 36 horas. O teor de matéria seca (MS) do bagaço de cana foi maior quando hidrolisado por 36 horas. O valor médio da proteína bruta foi de 2,4% e não foi influenciado pelo período, pela dose de óxido de cálcio nem pela interação período × dose de óxido de cálcio. Os teores de fibra em detergente neutro, fibra em detergente ácido, celulose e lignina diminuíram linearmente com a adição de óxido de cálcio. A digestibilidade in vitro da matéria seca, no entanto, aumentou 1,2%... |

| ABSTRACT Fermentation profile and microbial population were assessed in soybean silages without any additive (control), with inoculant (I), with I + powdered molasses (I+M), and with powdered molasses only (M). Soybean plants were harvested at the R6 stage and ensiled in 2kg-capacity laboratory silos. The additives were added to the natural matter base of silages. The assessed fermentation periods were 1, 3, 7, 14, 28, and 56 days. A 4 × 6 factorial arrangement (4 additives × 6 fermentation periods) in a completely randomized design with 3 replicates was used. Lactic, acetic, and butyric acids concentrations were influenced by additives and periods (P< 0.05). It was observed higher lactic acid values to control silages, on the 56th day. Lower average... |

| Microbial populations, pH, ammonium nitrogen/total nitrogen (N-NH3) ratio, concentrations of lactic acid, acetic acid and butyric acid and the chemical composition of Brachiaria decumbens cv. Basiliski silages at different regrowth ages (30, 40, 50, 60 and 70 days) were evaluated by using 2-kg capacity laboratory silos. It was used a 5 × 6 factorial scheme (5 regrowth ages × 6 fermentation periods) in a complete random design, with three replicates. The fermentation periods were 1, 3, 7, 14, 28 and 56 days. Lactic acid bacteria populations were recorded in fresh forage varying from 3.93 (30 days of regrowth) to 5.51 (70 days of regrowth) log colony-forming units (cfu)/g forage. Maximum populations of these microorganisms were recorded in the silages on the... |
