Digestibilidade in vitro do bagaço de cana-de-açúcar hidrolisado, submetido a diferentes tempos de estocagem e de adaptaçao ao bovino doador de fluido ruminal

An experiment was conducted to study the in vitro digestibility of dry matter (IVDMD) and gross energy (IVGED) of hydrolyzed sugarcane bagasse with different storage times and two periods of adaptation of the bovine to the diet. A completely randomized design with four treatments and five replications was used. Treatments A,B,C, and D which corresponded to the times of 0, 15, 30, and 45 days of storage time period of the bagasse, respectively. Each treatment was studied at 7 and 45 after adaptation of the bovine ruminal donor to the diet. After 30 days storage, the bagasse IVDMD was inpaired for both 7 and 45 days of adaptation. Averages values of 25.8; 25.9; 23.1 and 23.3 percent were obtained for IVDMD with seven days of adaptation, and 25.04; 21.6; 12.5 and 11.4 percent with 45 days of adaptation for storage periods of 0; 15; 30 and 45 days, respectively. For IVGED, the averages obtained were 33.4; 27.8; 30.9; and 27.2 percent with seven days, and 30; 26.6; 20.6 and 14.5 percent with 45 days of adaptation for storage periods of 0, 15, 30 and 45 days, respectively.
