This study evaluated the effects of substituting maize with the Federal University of Technology Akure multipurpose sweet sorghum (Sorghum bicolor) on African catfish (Clarias gariepinus) fingerlings. The Novel Federal University of Technology Akure Multipurpose Sweet Sorghum was obtained from the Department of Crop, Soil and Pest, FUTA Ondo State, Nigeria. A total of five experimental diets were formulated, with sweet sorghum replacing maize at varying levels, alongside an initial baseline group. The feeding trial lasted 56 days, with three replicates per treatment, water quality, haematology, blood biochemistry, whole-body proximate composition, and genomic expression were assessed. Results showed that water parameters remained within the optimal range for catfish culture, indicating no adverse environmental impact of sweet sorghum inclusion. Hematological and biochemical indices, including PCV, RBC, WBC, hemoglobin, total protein, albumin, and globulin, varied significantly (p < 0.05) among treatments. Fish fed sweet sorghum-based diets exhibited enhanced blood health markers compared to the control. Additionally, genomic expression analysis suggested a positive influence of sweet sorghum on physiological and immune-related gene regulation. Overall, substituting maize with sweet sorghum in catfish diets improved fish health, growth, and sustainability, while reducing reliance on conventional feedstuffs. Sweet sorghum can therefore serve as a viable, locally available, and cost-effective.
