A six weeks trial was conducted to investigate the effect of using different levels of grain sorghum in the broiler chicken diets as a replacement for corn on the growth performance, shank skin pigmentation score, carcass traits, caecal microflora and nutrient digestibility. Materials and Methods: Isocaloric/isonitrogenous diets were formulated where sorghum replaced corn at rates of 0% (control), 10, 25, 50 and 100% making 5 dietary treatments with 5 replicate pens per treatment. A total of 250-day-old-chicks (Cobb500) were randomly allocated into 25 pens with 10 birds per pen. Results: The obtained results revealed no significant differences in the body weight (BW), average daily gain (ADG) and feed conversion ratio (FCR) when sorghum replaced corn at levels up to 50%. The ADG was decreased and the FCR was increased when sorghum replaced corn at 100%. The average daily feed intake was not impacted by sorghum inclusion. The measured carcass traits and caecal microflora were not impacted by sorghum inclusion. The shank skin pigmentation score was significantly decreased by sorghum inclusion at 50-100%. The protein digestibility was significantly decreased when sorghum inclusion replaced corn at 100%. Conclusion: It can be concluded that sorghum is a good partial alternative for corn at levels up to 50% without negative impacts on the broiler chicken productivity.
