| Abstract | ||
| This study was conducted in the Poultry Farm of the Department of Animal Production/ College of Agriculture/ Anbar University- in the alternative site (Abu Ghraib from 6/10/2016 to 16/11/2016 (42 days), to evaluate individual and combining effects of adding zinc and vitamin E to the diet in productive and physiological traits of broilers under oxidative stress conditions. Oxidative stress was introduced by adding hydrogen peroxide (H2O2) to drinking water from 10 days with 0.5% For all treatments except the negative control treatment (first treatment) Two hundred and eighty two, unsexed one day old chicks (Ross 308) were used at average BW 38 g were randomly allotted into 8 treatments with 3 replicate pens per treatment and 12 broilers in each pen for 42 d. The first treatment is free of any addition (negative control), The second treatment included the addition of H2O2 0.5% to drinking water at the age of 10 days (positive control), the third and fourth treatments diets were supplemented with80 and 160 mg/ kg feed vitamin E respectively, while the fifth and sixth diets were supplemented with 40 and 80 mg/ kg feed zinc respectively. The seventh and eighth treatments diets were supplemented with zinc + vitamin E mixture (40+80 and 80+160 mg/ kg feed respectively), The results showed average body weight for broilers at the age of 6 weeks and the rate of weight gain cumulative (1 to 42 days) that all experimental treatments have improved significantly (P<0.05) on the treatment 2, The cumulative feed consumption of broiler s showed results high significant (P <0.01) in the treatments T1 and T8 compared to other treatments, It was also noted significant superiority (P<0.05) for T3 and T4 in the cumulative feed conversion coefficient compared to other treatments. Current results showed that supplementation with 80 mg/ kg of feed or zinc at 80 mg/ kg level fed individually or combination could improve the productive traits of broiler | ||
