This experiment was conducted to investigate the effects of using canola oil with vitamin E on carcass traits of broilers. This study was carried out as 3×2 factorial experiment with 3 levels of canola oil (control, 2.00 and 4.00 percent) and 2 levels of vitamin E (0 and 150 mg/kg) in 6 treatments, 3 replicates and 14 birds in each replicate in a completely randomized design.
In this experiment 252 day old broiler chicks were used for 42 days. Inclusion canola oil until 4% did not have any significant effects on performance of broilers (P>0.05). Inclusion 150 mg/kg vitamin E significantly affected the performance of broilers. The lowest amounts of daily weight gain (39.38g), daily feed intake (85.91g) and the highest ratio of feed conversion (2.19) were resulted by inclusion 150 mg/kg vitamin E. Inclusion 150 mg/kg vitamin E significantly affected the carcass traits of broilers. The lowest carcass (68.04%) and abdominal fat (2.76%) and the highest liver (4.12%) percents were resulted by inclusion 150 mg/kg vitamin E. As interactive effects; the lowest carcass percent (63.98%) were obtained by adding 4% of canola oil and 150 mg/kg vitamin E to broiler diets.
