Six hundred day old unsexed broiler chicks were used in a 42-d trial at Chittagong Veterinary and Animal Sciences University Poultry Farm to find out the effects of different oils on productive performance of broilers. The chicks were randomly distributed following a completely randomized design in four treatment groups having three replications per treatment. Each treatment had 150 birds, with 50 birds per replicate. Four diets were formulated using locally available ingredients as diet without oil, or diets containing 2.5% soybean oil, 2.5% palm oil and 2.5% fish oil. Results indicated that supplementation of diets with different types of oil significantly (P<0.05) improved live weight gain and feed consumption of broilers from the 3rd to the 5th wk. However, supplementation caused no significant (P>0.05) impact on feed conversion of broilers during 1-5 wk. Feed conversion improved (P<0.05) only during the 6th wk. Out of all carcass parameters, only feather weight, dressed weight, digestive tract weight and head weight differed (P<0.05) at the 4th wk. The survivability of broilers fed different types of oil was similar. It could, therefore, be inferred that the inclusion of soybean oil, palm oil and fish oil had a positive impact on weight gain, feed consumption and feed conversion in commercial broilers.
