The poultry industry in Sudan relies heavily on locally available alternatives such as sorghum and peanut meal, which offer potential cost advantages but are constrained by variability in nutrient composition, anti-nutritional factors and amino acid imbalances. This study aimed to conduct a comparative nutritional and economic evaluation of corn-soybean and sorghum-peanut-soybean base mixes for broiler diets under Sudanese conditions. Six broiler base mix scenarios were formulated using combinations of imported corn, local and imported sorghum, soybean meal, and peanut meal. All base mixes were standardized to contain 3200 kcal/kg metabolizable energy, 22% crude protein, and 1.00% digestible lysine through appropriate adjustment of ingredient inclusion rates, sunflower oil, and synthetic lysine. Local market prices and CIF import prices were used to estimate base mix costs, excluding fixed-cost additives to allow unbiased comparison. The results indicated that base mixes containing local sorghum partially or fully replacing imported corn significantly reduced base mix cost compared with the corn-soybean benchmark. Diets relying exclusively on sorghum and peanut meal required higher levels of lysine supplementation and energy correction, reducing their economic advantage. The lowest base mix cost was achieved when local sorghum was combined with moderate inclusion levels of both peanut meal and soybean meal, providing a balance between cost efficiency and nutritional adequacy. Importantly, the use of soybean meal may eliminate the need for imported protein concentrates commonly included at approximately 5% in Sudanese poultry feeds, thereby simplifying formulations and reducing overall import dependency. The study demonstrates that strategic partial substitution of imported ingredients with local sorghum, supported by limited soybean meal inclusion and amino acid correction, offer the most balanced approach in terms of nutritional adequacy, economic efficiency, and feed system sustainability in Sudan. These findings support policies that encourage both the rational importation of soybean meal and the long-term development of local soybean production and proper processing capacity to enhance feed security and sustainability.
