The nutritional value of Xaraes and Piata palisadegrass silages wilted or with additives wasevaluated in a completely randomized design (2x4 factorial arrangement), being two cultivars of Brachiariabrizantha (Xaraes and Piata palisadegrass) and four ensiling methods as treatments T1- control, in naturaforage (INF); T2 INF wilted for 4 hours under the sun; T3- INF + bacterial additive (BactoSilo®Lallemand) 2 g ton-1 of in natura forage; T4 INF + 15% of pearl millet meal. For ensiling, the grasses wereharvested in the growth stage of 40 days, at 20 cm from the ground level. The addition of the inoculant andmillet meal improved the fermentative and chemical parameters of both cultivars silages, by increasingsoluble carbohydrates (SC), CP and TDN contents and reducing ammonia-nitrogen and pH. Because ofits composition, 15% of millet meal inclusion affected SC, NDF, ADF and increased the IVDDM ofsilages. Bacterial inoculant or millet meal inclusion enhanced the nutritional value of Brachiaria brizanthasilages and, could have a positive performance response on ruminants fed with these silages. Wilting wasalso effective in improving the fermentative stability of grass silages and may be a cheaper alternative to additives.
