The use of such agricultural by product as corn cobs is important in fulfilling the needs of feed for ruminant, especially during the dry season. However, the main problem of using corn cobs as a feedstuff is low digestibility due to the existence of the links between lignin and cellulose or hemicellulose. This study was designed to evaluate the effects of biodecomposer (BS) application on the changes of chemical components of corn cobs. BS was developed from the rumen bacterial of buffalo raised under typical feeding conditions. The effectiveness of BS application was assessed by fermenting corn cobs for 4 weeks. The experiment was run according to completely randomized design consisted of eight treatments and three replications giving total number of the experimental units of 24. The treatments were T0 = 100 g course ground of corn cobs without BS, T1 = 100 g course ground of corn cobs + 2.5% BS, T2 = 100 g course ground of corn cobs + 5.0 % BS, T3= 100 g course ground of corn cobs + 7.5% BS, T4= 100 g course ground of corn cobs + 10% BS, T5 =100 g course ground of corn cobs + 12.5% BS, T6= 100 g course ground of corn cobs + 15% BS, and T7= 100 g corn cobs + 0.6% Starbio (commercial biodecomposer). Increasing level of biodecomposer is expected to have a significant effects on the chemical composition in the corn cobs.
