AB  - The production parameters including Body Weight Gain (BWG), Feed Intake (FI) and Feed Ratio (FCR) were monitored weekly and the carcass properties and abdominal fat deposition were measured in different slaughter age ( 28 and 42 day). All diets were isocaloric and isonitrogenic. BWG, FCR, FI and carcass properties was significantly (p< 0.05) improved with the increase of soybean oil levels in broiler chicken diets. But, these increases were not significant between 4 and 6 SBO levels. The experiment diet contain 4% SBO had a higher FI in 7-21 and 7-42 days of age. The birds fed with diets contain 2 and 6% SBO had lowest and highest FCR, respectively (p< 0.05). Also, the birds feed with 6% SBO had a highest carcass, thigh and breast yield percentage than other treatments. Although, with the increasing of SBO levels in broiler diets the abdominal fat deposition increased. But, there was not significant difference between treatments in abdominal fat deposition. Antibody titers  production against Infections Bursal Disease Virus (IBDV) was  significantly (p< 0.05) affected by dietary treatments. And with  addition of SBO to diets, it’s  increased (p< 0.05). The results  of  this experiment suggests that the  increasing of  SBO levels in broiler diets improved growth performance, carcass and parts of carcass yield and enhanced humoral immune response.
