The aim of this experiment was to study optimilization of rice and bran straw based diet with nutrient rich supplement (NRS) on in vitro fermentability and digestibility. The fermentability experiment used factorial randomized block design 4×3 with four replicates. The ration treatments (60% rice straw : 40% nutrient rich supplement (NRS)) were factor P: P1 = Rice straw + NRS A1 (rice bran, fish meal, cassava leaf meal, Leucaena leaf meal, Sesbania leaf meal molases and mineral mix), P2 = Rice straw + NRS A2 (rice bran, fish meal, cassava leaf meal, Gliricidia sepium leaf meal, molases and mineral mix), P3 = Rice straw + NRS A3 (concentrate A2 + tea waste), and P4 = Rice straw + NRS A4 (concentrate A3 + Hibiscus rosasinensis leaf meal). Factor B was incubation times: 1, 3, and 5 hours. The digestibility experiment used randomized block design with four ration treatments (P1, P2, P3, P4) and four replications. The result showed that supplementation did not influence all variables measured, but protozoal population, VFA concentration and dry matter degradability were affected by incubation time.
