This experiment was carried out to evaluation usage different levels of Canola Oil (CO) (0, 2 and 4%) and Choline Chloride Supplement (CCS) (0, 500 and 1000 mg/kg) in the basal diets (corn and soybean meal) and their effect on the Japanese quails performance. This trial was conducted in 3 × 3 factorial experiment with Completely Randomized Design (CRD) with 270 male quail. All diets were isoenergetic and isonitrogenous and balanced with NRC recommendation. Result shown that interaction effects of CO and CCS could affect Live Body Weight (LBW), Feed Intake (FI) and Feed Conversion Ratio (FCR). In quails, CO and CCS in 9 and 6 treatment (T9 = 4% CO + 1000 mg/kg CCS and T6 = 2% CO + 1000 mg/kg CCS) could significantly increase the LBW, respectively (p<0.0001) and CO and CCS in 6, 9 and 8 treatment (T6 = 2% CO + 1000 mg/kg CCS, T9 = 4% CO + 1000 mg/kg CCS and T8 = 4% CO + 500 mg/kg CCS) could significantly increase the feed intake (p<0.0001).
