This research wasconducted to evaluate the effects of burning and additivess (urea, sodium benzoate,sodium hydroxide (NaOH), Propionibacterium acidipropionici + Lactobacillusplantarum and Lactobacillus buchneri) on sugar cane silage. A randomizedcomplete design was used, in a 2 × 6 factorial scheme with two sugar caneforages (natural or burned) and six treatments (five additive sources plus acontrol) with three replications. The gas and effluent losses during the fermentationprocess and dry matter recovery (DMR) were determined. Greater DMR was observedin the burned sugar cane silage (77.3%) compared to the crude silage (73.1%).Among the additives, greater DM recovery was observed in the silages treatedwith the NaOH or L. buchneri silage, that showed 84.0% DMR, and the controlsilage with 69.0%. After opening, an important aspect is the inhibition of pHelevation, in this case, measured by the variation in the pH values (VpH). Sodiumbenzoate and L. buchneri were efficient inhibitors of the VpH, showingvalues of 0.05 and 0.18 per pH unit, respectively. Ensiled sugar cane withoutadditives, raw or burned, is a strategy that presents high quantitative losses.L. buchneri effectively reduces losses during the fermentation and post-openingphases of raw or burned sugar cane silage.
