The objective was to evaluate the fermentation pattern and chemical composition of elephant grass silage using different additives. The experimental design was completely randomized with six treatments (elephant grass no additive; with 100 kg of rice bran [ton.sup.-1] of green mass (GM); with 100 kg of soybean hulls [ton.sup.-1] GM; with 100 kg of corn meal [ton.sup.-1] GM; with 200 kg of sugar cane [ton.sup.-1] GM; with inoculants) and four replications. PVC silos were used, adopting a density of 600 kg of green mass [m.sup.-3]. With the exception of inoculant, all additives used resulted in increased dry matter content (27.95 to 31.65%) and soluble carbohydrate contents (15.20 to 17.14%) in the forage being ensiled. The additives promoted an adequate fermentation pattern for pH values (3.70 to 3.96) and ammonia nitrogen (3.67 to 4.44% of total N) observed in the silage. The rice bran additive yielded silage with higher contents of crude protein (6.41%) and total digestible nutrients (61.91%) compared to the treatment without any additive. Keywords: soluble carbohydrates, rice bran, ammonia nitrogen, pH. Objetivou -se avaliar o padrao de fermentacao e a composicao bromatologica da silagem de capim-elefante utilizando diferentes aditivos. Utilizou-se o delineamento inteiramente casualizado com seis tratamentos (capim-elefante sem aditivo; com 100 kg de farelo de arroz [t.sup.-1] de massa verde (MV); com 100 kg de casca de soja [t.sup.-1] MV; com 100 kg de fuba de milho [t.sup.-1] MV; com 200 kg de cana-de-acucar picada [t.sup.-1] MV; com inoculante bacteriano) e quatro repeticoes. Utilizaram-se silos de PVC, adotando densidade de 600 kg de massa verde [m.sup.-3]. Com a excecao do inoculante bacteriano, todos os aditivos proporcionaram aumento nos teores de materia seca (27,95 a 31,65%) e carboidratos soluveis (15,20 a 17,14%) na forragem a ser ensilada. Os aditivos promoveram adequado padrao de fermentacao face aos valores de pH (3,70 a 3,96) e de nitrogenio amoniacal (3,67 a 4,44% do N-total) verificados na silagem. O aditivo farelo de arroz proporcionou a obtencao de silagens com teores mais elevados de proteina bruta (6,41%) e nutrientes digestiveis totais (61,91%) em relacao ao tratamento sem aditivo. Palavras-chave: carboidratos soluveis, farelo de arroz, nitrogenio amoniacal, pH.
