| Resumo: |
This trial aimed to evaluate the effects of the time post-burning, and additives on fermentative characteristics, losses and chemical composition on the sugar cane silage. The sugar cane variety IAC 86-2480 was ensiled on the 1, 4, 7, 10 and 14 days after burning. The additives evaluated were: control (Cont.), Lactobacillus buchneri (LB), Calcium oxide micro pulverized (CO), and Lactobacillus buchneri (LB) plus Calcium oxide micro pulverized (LB + CO). The yeast population was determined before ensiled. After 56 days of the fermentation period the silos were opening to take samplings. The experimental design was a completely randomized design, in a factorial scheme (additive and burning time) with seven treatments and four replications. The sugar cane was recontaminated with yeast, the populations increased from 5.04 to 6.48 log cfu/g of forage. Dry matter content decreased after fermentation period in average 7.6 units, compared to the sugar cane forage before ensilage. Control and LB silage showed lowest dry matter recovery (DMR), 613 g/kg and 631 g/kg, respectively, compared to the Cal and LB + Cal, 807 g/kg and 832 g/kg. This fact probably was associated to the calcium oxide control on the yeast populations. In relation to the time post-burning, the greatest changes were observed in the gas production and DMR. Gas production were higher in the first days post-burning and decreased in response to the prolongation time post-burning. The time post-burning alters the nutritive value of the fresh sugarcane and its silage and also the size of the losses from the ensilage process.
