This study aimed to evaluate the capability of tropical endemic herbivore fecal inoculum in the fiber degradation and fermentation in vitro. The research used a 2x5 factorial block design and each treatment consisted of 5 replications. The first factor was roughage sources i.e Napier grass and rice straw, and the second factor was inoculum fecal from the five tropical endemic herbivore animals i.e Anoa, Bison, Sumatran Elephant, Muntjak, and Timor Deer. The data obtained were tested using analysis of variance (ANOVA) and the differences among treatments were further analyzed using Duncan’s multiple range test. The results showed that there was an interaction between roughage sources and fecal inoculum sources on dry matter digestibility (DMD), organic matter digestibility (OMD) and ammonia production. The dry matter and organic matter digestibility, ammonia production of rice straw were lower than Napier grass. The microbe from Elephant fecal inoculum has the highest capability to digest dry matter and organic matter, the lowland Anoa (Bubalus depressicornis) fecal inoculum has the highest ammonia production. There was no interaction between roughage sources and fecal inoculum sources on the pH value, total VFA production, and total bacteria population. The pH value, total VFA production, and total bacteria population of in vitro incubation were similar among treatments. In conclusion, cellulolytic microbe from fecal inoculum of tropical endemic herbivores have capability in the fiber degradation and fermentation.
