Abstract: This experiment was conducted to evaluation usage different levels of Canola Oil (CO) (0, 2 and 4%) in the basal diet (corn and soybean meal) and effects on the broiler chicks liver and blood chemical parameters include cholesterol and triglyceride contents. A total of 90 Ross 308 strain were randomly divided in to 3 experimental treatments with 3 replicates (10 chicks per pen) and arranged in a completely randomized design. The experimental period lasted 6 weeks and during this period, the birds had free access to feed and water. Experimental diets consisted of: Basal diet 0% canola oil, basal diet with 2% canola oil and basal diet with 4% canola oil. These diets were isonitrogenous and isoenergetic were given to broiler chickens throughout a 42 day growth period. Data was analyzed with one way ANOVA and means compared with Duncan test. Result for liver chemical analyses showed canola oil in levels of 4 and 2% (T3 and T2, respectively) decrease the cholesterol and triglyceride contents numerically and blood chemical analyses showed treatment of 3 and 2 (contain 4 and 2% canola oil, respectively) decrease the cholesterol and triglyceride contents significantly (p<0.05), too Canola oil could increase significantly high density lipoprotein cholesterol (HDL) content in blood (p<0.05), but no significantly affected on blood Low Density Lipoprotein cholesterol (LDL) content. Canola oil was decrease LDL content in blood numerically.
