Growth performance and feed utilization parameters were significantly (p<0.05 0.01 and 0.001) better in the test diets. Result indicated an improved formula quality as the formulation progressed from 60 to 85% probability level thereby taking care of the nutrient variability problem. The formulated rations were tested on catfish fingerlings (20.15-20.50 g) twice daily for 6 days a week in triplicate groups of experiments for 150 days in earthen ponds for growth performance and feed utilization. The control diet was formulated using linear programming technique at 50% probability level while the test diets were formulated by stochastic programming technique at 50, 60, 70, 80 and 85% probability levels. Five isonitrogenous (32% CP), isocaloric (2800 kcal kg -1) and isolipidic (6.00% lipids) diets were formulated. The aim was to minimize the risk of not meeting the nutrient requirements through under formulation and overformulation which will result in high cost. ![]() This study was undertaken to capture nutrient variability in least-cost feed formulation for African catfish ( Clarias gariepinus) using stochastic programming technique.
