This experiment was aimed to investigate the effect of rice bran supplementation on live weight gain (LWG), the proportion of carcass meat, bone and fat of Thin Tail Rams. Twelve thin tail rams, aged about 12 months, weighed 20.95 ± 1.52 kg (CV = 7.26%) were allocated into a Randomized Block Design with 2 blocks and 3 treatments. The treatments applied were levels of rice bran supplementation, i.e. Napier grass ad libitum without rice bran (T1), Napier grass ad libitum and 200 g rice bran (T2) and Napier grass ad libitum and 400 g rice bran (T3). The results showed that rice bran supplementation highly significantly (P0.05) influence the percentage of carcass meat and bone percentage. It was concluded that rice bran supplementation increased slaughter weight, carcass weight and carcass percentage, carcass meat and bone weight, and carcass fat percentage, but did not influence the percentage of carcass meat and carcass bone.
