This experiment was conducted at the Goiano Federal Institute on the Rio Verde campus in Goiás State, Brazil. The experimental design was entirely random with four replications in a 4 × 5 factorial scheme that included four energetic brans (millet, maize, sorghum and wheat) and five levels (0%, 8%, 16%, 24% and 32%). The energetic brans can be considered as a good source of additives for Piata palisadegrass ensiling, which improves the qualitative and nutritional fermentative characteristics of the silage. The maize and wheat brans were the most efficient for improving the fermentative characteristics of the silage. However, millet bran was the most efficient for improving the bromatological characteristics. In addition, the wheat bran had the greatest influence on the final production cost and the sorghum and millet brans were the most economically feasible. Overall, the addition of 24% bran is recommended due to its beneficial impact on silage quality and the average final production cost of the silage.展开更多
