Silages making is a solution to overcome the shortage or excessive of forages in Indonesia. The objective of this study was to evaluate the effect of rice bran as carbohydrate source and Lactobacillus plantarum 1BL-2 addition on the quality of napier grass (Pennisetum purpureum) silages. The concentrations of rice bran and Lactobacillus plantarum 1BL-2 added were 0%,1%, 3% and 5 % (w/w) and incubated for 30 days. The results showed that the addition of 1%-5% rice bran significantly affected (P<0.05) pH value, total acid, NDF, ADF compared with controls. While temperatures, damage level, dry matter, lactic acid, colony of lactic acid bacteria, crude ash, and organic matter were not significantly affected by treatments. Damage level evaluated from all treatments was quite low, which was not more than 2%. Treatments used did not significantly affect silages quality. Therefore, rice bran addition at the lowest level (1% (w/w)) was suggested to be applied as carbohydrate source additive if combined with Lactobacillus plantarum 1BL-2.
