ABSTRACT This study examined the quality of silage from two cultivars of energy cane (Saccharum spontaneum) produced with different additives. The experiment was laid out in a completely randomized design with a 2×5 factorial arrangement of treatments consisting of two cultivars (VG3, VG1126) and four additives (1% urea; 1% NaOH; 1% CaO; and 1.0 × 1011 CFU g-1 of Lactobacillus plantarum- LP) + control, with eight replicates. Experimental mini-silos were used, which were opened 72 days after ensiling. The dry matter (DM), crude protein (CP), organic matter (OM), mineral matter (MM), ether extract (EE), neutral detergent fiber (NDF) and acid detergent fiber (ADF) contents, and silage degradability were. We identified significant interactions effect between cultivar and type of additive for DM, CP, EE, NDF. ADF. Organic and mineral matter percentage were similar between the two cultivars. LP was the least beneficial additive for DM degradation.After 72 h of fermentation, in vitro NDF degradation of cultivar VG3 increased due to urea, NaOH, and CaO, whereas degradation cultivar VG1126 decreased when inoculated with LP or CaO. The NaOH and CaO improved silage degradability thus improving its quality. The use of LP in the present study did not benefit silage for energy-cane cultivars. The use of NaOH and CaO improves the quality of the silage, two varieties of sugarcane energy VG3 and VG1126, enabling its use with better efficiency for animal feed.
