An experiment was conducted to study the effect of different levels of replacement of sunflower oil in place of soybean oil in broiler diets. Control diet had 5% soybean oil and/or sunflower oil at five levels of oil inclusion (25,50,75,100%). Diets were administrated to broilers from 1 to 42d of age. LDL, HDL and weight of thigh, breast, heart, pancreas and abdominal fat were not affected by type of oil fed. Broilers fed soybean oil were little efficient. HDL percent was lower in animals fed sunflower than in those fed soybean oil. Breast weight was significantly higher for birds fed sunflower oil. The fatty acids profile of the different tissues was reflected little to the dietary fatty acid profile of the oils. The result suggests that sunflower oil can replace soybean oil as suitable fat resource without any significant effects on total weight gain, feed intake and FCR in chicken diet.
