Resumo

The nutritional value of Xaraes and Piata palisadegrass silages wilted or with additives was evaluated in a completely randomized design (2x4 factorial arrangement), being two cultivars of Brachiaria brizantha (Xaraes and Piata palisadegrass) and four ensiling methods as treatments: T1- control, in natura forage (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 were harvested in the growth stage of 40 days, at 20 cm from the ground level. The addition of the inoculant and millet meal improved the fermentative and chemical parameters of both cultivars silages, by increasing soluble carbohydrates (SC), CP and TDN contents and reducing ammonia-nitrogen and pH. Because of its composition, 15% of millet meal inclusion affected SC, NDF, ADF and increased the IVDDM of silages. Bacterial inoculant or millet meal inclusion enhanced the nutritional value of Brachiaria brizantha silages and, could have a positive performance response on ruminants fed with these silages. Wilting was also effective in improving the fermentative stability of grass silages and may be a cheaper alternative to additives.
