The digestibility and fermentation parameters of the diets containing leaf, pod and seed of the Subabul tree in sheep was determined by using two steps digestion and gas production (GP) methods. The experimental diets consisted of 0.0 (control), 25, 50, 75 and 100 percent of the leaf, pod and seed of the Subabul tree that were replaced with alfalfa in diets of sheep. Diets containing 50 percent seed of the Subabul had higher GP compared to the control diet (P<0.05). The highest true digestibility of organic matter in Subabul leaf was belonged to diet contains 100 percent leaf. The diet contain 100 percent had the highest partitioning factor (PF) and microbial biomass efficiency (P<0.05) compared to other levels of the Subabul pod. The digestibility of DM, NDF and ADF of diets contain the pod of the Subabul tree for all levels were less than control (P<0.05). There are no significant differences between digestibilities of NDF and ADF of diets contain up to 75 percent the leaf of the Subabul tree and others diets. Digestibility of DM, NDF and ADF was more than control diet (P<0.05) by increasing the amount of the seed of the Subabul tree in the diets (75 and 100 percent of the seed of the Subabul). According to the results, the leaf and seed of the Subabul can be replaced up to 100 percent with alfalfa in the diets of sheep without any negative effect on fermentation and digestion. The nutritional value of sheep diets can be improved by replacing the alfallfa with Subabul tree seeds.
