A smallholder keeps a flock of 40 laying hens. Each bird requires 120 g of concentrate feed per day containing 18 % crude protein and 4 500 kcal kg⁻¹ metabolizable energy. The farmer wishes to partially replace the concentrate with locally available maize grain (86 % carbohydrate, 9 % protein, 3 600 kcal kg⁻¹). The flock produces an average of 55 eggs per bird per month and each egg sells for ₦30. Concentrate costs ₦150 per kilogram and maize costs ₦120 per kilogram.
