The experiment was conducted to evaluate the effects of different sources and levels of vegetable oils on performance, carcass traits and accumulation of vitamin E in breast meat of broilers. In this experiment336 day old broiler chicks (Ross-308 strain) were used in a completely randomized design for 42 days with 8 treatments in 3 replicates and 14 chicks in each replicate. The experimental groups included: T1) control group, T2) diet with 4% of sunflower oil, T3) diet with 4% of canola oil T4) diet with 4% of soybean oil, T5) diet with 2% of sunflower oil+2% of canola oil, T6) diet with 2% of sunflower oil+2% of soybean oil, T7) diet with 2% of canola oil+2% of soybean oil and finally T8) diet with 1.33% of sunflower oil+1.33% of canola oil+1.33% of soybean oil. According to the results, inclusion different sources and levels of vegetable oils in broiler rations significantly affected their performance, carcass traits and Vitamin E content of breast meat (p＜0.05). The best feed conversion (1.83) was obtained in group 7, whereas the lowest percent of gizzard (2.52%), and the highest amount of vitamin E in breast meat (22.05mg/kg) were observed in group 8.
