A total number of 180 unsexed 7 days old Hubbard broiler chicks were used in this study to assessment of using scrape crude corn oil (SCCO) as an alternative energy source in broiler diets on growth performance, carcass characteristics and economic efficiency. Chicks were divided randomly into six equal treatments (30 birds each). The experiment lasted from 7 to 40 days-old and contained 6 treatments diets which contained different levels of (SCCO) 0, 20, 40, 60, 80 and 100%, respectively. Results of this experiment showed that, no significant differences between experimental treatments for live body weight (LBW) and daily weight gain (DWG) during the experimental periods. There were no significant differences among treatments for daily feed consumption (DFC) and feed conversion ratio (FCR) during the experimental period. There was no significant effect in carcass traits among treatments. The results showed that the feed price of the diet decreased as the inclusion level of (SCCO) increased as compared to the control group. The relative economic efficiencies of the diets containing 60, 80 and 100% SCCO were higher than other groups. It can be concluded that, scrape crude corn oil can be completely replace corn oil in broiler diets from 7 to 40 days of age without adversely affecting on broiler performance, carcass characteristics and improved relative economic efficiency.
