Soybean meal (SBM) is an important protein source in poultry feeds. Heat processing was used to overcome anti-nutritional factors. This experiment's objectives were to evaluate Sudan 1 soybean meal (SBM) heat processing on performance, carcass characteristics, and economic evaluation of broiler chickens. A total of 120 one-day-old male Ross 308 broiler chicks were allocated randomly to four dietary treatments using a completely randomized design. Each treatment was of three replicates and 10 birds in each. Treatment one T1 (un-processed SBM), T2 (RSBM15), T3 (RSBM20) and T4 (RSBM25). SBM was roasted at 120°C for 15, 20 and 25min, respectively. RSBM15 significantly (P?0.05) reported the best body weight (BW), body weight gain (BWG), feed intake (FI), and feed conversion ratio (FCR). RSBM15 had significantly (P?0.05) the best results in carcasses and some carcass parts’ weights (breasts, thighs, wings, and drumsticks) and dressing percentages, the economic appraisal. The gastrointestinal tract (gizzards, intestines, livers, hearts, and pancreas) and abdominal fat pad weights were significantly (P?0.05) different. All treatments had insignificant differences in mortality rates and sensory properties (color, taste, flavor, and tenderness). The economic assessment was the best for RSBM15. It can be revealed that RSBM15 had the best performance parameters. It was concluded that Sudan 1 soybean meal roasted at 120°C for 15min can be a good protein supplement in broiler feeding. Further studies are recommended for the different Sudanese soybean varieties meals.
