Research about the performance of local rabbit fed different level of concentrate based on Daucus carota L.was conducted for 12 weeks at Dajan Peken Village, Tabanan District, Tabanan Regency. The research design used was Randomized Block Design with 5 replicates. The animals were allocated randomly into 4 treatments i.e. control ration carrot leaf (Daucus carota L.) (R0), control ration with 10 g concentrate/head/day (R1), control ration with 20 g concentrate/head/day (R2) and control ration with 30 g concentrate/head/day (R3). Daucus carota L. and drinking water offered ad libitum. Results of the research showed that performance of the animals fed control ration with 30 g concentrate/head/day (R3) was higher (P < 0.05) than that R0 (control) and other treatments. Carcass weight, meat, and fat of the animals fed ration R0 was lower (P < 0.05) compare to treatment R1, R2, and R3. There was no significant difference (P >0.05) to variables of carcass weight, bone weight, and meat bone ratio among R0, R1, R2, and R3 percentages. It could be concluded that the animals fed Daucus carota L. as basic ration that was supplemented with concentrate 30 g/head/day produced higher performance and carcass compare to the animals supplemented 20 g/head/day and 10 g/head/day.
