The ensiling of sugarcane is increasing but little research has been carried out to reduce nutrient losses during fermentation.   Material and methods  The tested cultivar was SP70-1143. The production observed at 15 months of vegetative growth was 80 t/ha with 16% of pol (sucrose in sugarcane juice). Following factorial scheme with three inoculations (control, Propionibacterium acidipropionici (cepa MS 01) (PROP) + Lactobacillus plantarum (Cepa MA 18/50) and Lactobacillus buchneri (Cepa NCIMB 40788) (BUCH)) and four chemical additives (control, urea (1.5% DM), sodium benzoate (0.1% DM) and sodium hydroxide (1% DM)), with three replications was evaluated. In vitro dry matter digestibility (IVDMD) was estimated as amount of residual digestible DM in relation to digestible DM ensilaged, and dry matter recovery (DMR) was determined. This work aimed to evaluate quantitative and nutritional losses during the fermentative process associated with sugarcane ensilage.  Results  Silage treated with BUCH in relation to those inoculated and silages treated with NaOH compared to those treated with chemical additives had higher IVDMD. There were synergic effects between BUCH and NaOH (Table 1). Higher IVDMD means that the silage nutritive value was maintained in relation to original forage. The yeast activity is intense during sugarcane ensilage (Alli et al., 1983 and Pedroso et al., 2002) promoting high soluble sugar consumption and, consequently, reduction in DM and IVDMD. Inoculation with BUCH controlled yeast population, probably because of their capacity for acetic acid production, which reduced the quantitative and qualitative losses in sugarcane ensilage.

Association of microbial inoculums aiming to control losses provoked by yeast and NaOH seems to be an alternative for enhancing the effects of inoculums.  References Alli, I., R. Fairbairn, B.E.
