Rice straw is an agricultural waste in Indonesia that can be used as animal feed. This study aimed to determine the effect of rice straw with various treatments (physical, chemical, biological and combinations) against the percentage of carcasses, slaughter weight and fat percentage of the local rams. The experiment was conducted at the Laboratory Animal Sciences Program Faculty of Agriculture, Animal Husbandry University of North Sumatra for 4 (four) months starting from March to June 2012. This research method using 20 rams with an average initial body weight range 11.16 ± 0.98 kg and 3month age range. The research method used was a completely randomized design (CRD) consisting of 4 treatments and 5 replications. The treatments used were P1 (rice straw processed physically (chopper) + concentrate), P2 (rice straw treated with the chemical (NaOH) + concentrate), P3 (straw treated with biological(Aspergillusniger)+concentrate)andP4(ricestraw+concentratesprocessedincombination). The results showed that administration of rice straw in carcass weight parameter obtained results are significantly different P> 0.05. Carcass percentage, fatty heart, kidney fat and the pelvic fat were not significantly different P> 0.05 level. Carcass weight, carcass percentage, fat percentage heart and kidney fat washighestinP3treatment, whereascarcassweightand carcasslowest percentagecontainedintheP2 treatment. The conclusion of this study is the presence of rice straw with various treatments (physical, chemical, biological and combined) in sheep feed is still a positive influence where the provision of rice strawwithvarioustreatmentsdonotreducethe weightoftheramcarcass.
