Abstract: 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 1) in the basal diet (corn and soybean meal) and their effects on the broiler chicks liver chemical parameters include cholesterol and triglyceride contents. This trial was conducted in 3×3 factorial experiment with Completely Randomized Design (CRD) with 270 male chicks (Ross 308). All diets were isoenergetic and isonitrogenous and balanced with NRC recommendation. Two male birds selected with each pen and slaughtered. Result for liver chemical analyses show that interaction effects of canola oil and choline chloride supplement could affected liver cholesterol and triglyceride contents. Canola oil and choline chloride supplement in 6 and 9 treatment (T6 = 2% CO+1000 mg kg 1 CCS and T9 = 4% CO+1000 mg kg 1 CCS) could significantly decrease the liver cholesterol and triglyceride contents respectively (p<0.0001). Result shown the levels of 1000 and 500 mg kg 1 choline chloride supplement is highest effect on the liver cholesterol content respectively. Afterward of 6 and 9 treatment, 8 and 5 treatment (4% CO, 500 mg kg 1 CCS and 2% CO, 500 mg kg 1 CCS, respectively), could significantly decrease the liver cholesterol and triglyceride contents (p<0.0001). Generally choline chloride in all diet treatment can decrease the levels of liver triglyceride and cholesterol content significantly (p<0.0001).
