This study was aimed at examining effects of rice straw-based feed and concentrate supplemented with solid or liquid probiotic on in vitro fermentation and digestibility. This study consisted of two factors; Factor A : feed treatment with a ratio 60:40% of a mixture of rice straw (RS) and concentrate; A1 = RS + control concentrate (10% CP), A2 = RS + optimal concentrate (12% CP), A3 = RS + suboptimal concentrate (14% CP). Factor B : probiotic treatment; B1 = without probiotic (0%), B2 = solid probiotic (0.25% b/b), B3 = liquid probiotic (0.10% v/b). A factorial randomized block design (RBD) 3 x 3 (4 replications) was applied. The result showed that ammonia and total VFA concentrations and digestibility were influenced by probiotic supplementation whereas bacterial populations were affected by feed treatments and probiotic supplementation; however, these treatments did not significantly affect protozoal populations and microbial protein synthesis. A3 is the best feed treatment that can be used, and liquid probitic supplementation (B3) is the optimal treatment.
