Abstract

Two hundred forty one-day male broilers (Ross 308) were divided in 3 treatments (with 4 replicate and 20 chicks for a replicate). All of broilers reared under a cold environmental temperature to induce ascites. Experimental treatments were included 1- was fed a commercial corn-soybean meal- based diet (0 mg of Coenzyme Q₁₀), 2- 20mg per kg of Coenzyme Q₁₀+ Control 3- 40mg per kg of Coenzyme Q₁₀+ Control. Body weight gain, feed intake and feed conversion ratio were measured from week 3. Blood parameters were determined at days 21 and 42 of age. At 42 days of age, 2 chicks from each replicate were randomly selected and slaughtered and then ascetic Index (ratio of right ventricle weight to total ventricle weight) calculated. Results of performance showed: 40mg/kg coenzyme Q₁₀ treatments had the lowest feed conversion ratio in total period (p<0.05). Blood parameters results showed that 40mg/kg coenzyme Q₁₀,significantly increased plasma concentration of triiodothyronine (T₃) and decreased urea, triglyceride and red blood cells, at day 42 (p<0.05).Moreover, 40mg/kg coenzyme Q₁₀significantly increased HDL and decreased cholesterol at day 21 and 42. It is also, ascetic Index and mortality due to Ascites, were significantly lower in 40mg/kg coenzyme Q₁₀, group (p<0.05). In concluded, 40mg/kg coenzyme Q₁₀ improved growth performance and reduced mortality due to ascites in broilers with ascites.
