CHEMICAL EVALUATION OF SELULOLITIC MICROBE AND LACTIC ACID BACTERIA NWD 015 ADDITION to Pennisetum purpureum AT SILAGE PROCESS

Abstract

Celulolytic microbes isolate, lactic acid bacteria (LAB) NWD 015 were used as starter for Peniisetum purpureum (PP) silage fermentation. The fermentation have an objective to improve the nutritive value of PP. There were three different fermented PP. In respect to various starter used, Fl using selulolitic microbes, F2 using LAB NWD O15, and F3 using selulolitic microbe and F4 using LAB NWD 015. After three weeks fermentation sample were taken out to the analysis their nutritive value which were include moisture, dry matter, fat, crude protein, crude fiber, NDF, ADF, ash and pH. The result of the experiment showed that the fermentation improved of nutrition value (P<0.05). The pH decresed significantly and the crude protein, crude fat as well as ash increased significantly. However, the crude fiber, NDF and ADP decrease, eventhough those value did not show significantly. From this study could be concluded that mixed isolate selulolitic microbe and LAB NWD 015 as starter were given the best result.
