Totaly, 184 broiler chicks were used in this investigation in which the availability ot by-products of oil industry in broiler rations was investigated. The growth performance, weight of carcass and abdominal fat and amounts of fatty acids in abdominal fat ol broilers fed diets consisting 5 % sunflower crude oil, sunflower soapstock, acidulated sunflower soapstock and volatile matters were determined. The trial was lasted in 49 days. The highest feed consumption and feed efficiency values were determined in broiler group fed acidulated soapstock. The lowest feed consumption and the highest average live weight values were found in the group fed the diet containing sunflower crude oil. It was concluded that the use of by-products of oil industry in broiler diets as energy source will use without any harmful effect on broiler performance and contain more omega-3 fatty acids which is very important for human health.
