Cost-Benefit Analysis of Replacing Fish Meal with Black Soldier Fly (Hermetia illucens) Larvae Meal in Broiler Diets

Rising inflation and overfishing have increased the cost and reduced the sustainability of fish meal, prompting the search for alternative protein sources in poultry production in Nigeria. This study evaluates the cost-benefit and performance outcomes of using black soldier fly larvae meal (BSFLM) as a substitute for fish meal in broiler diets. Fifty (50) broilers were assigned to five dietary treatments (T1, T2, T3, T4 and T5) with 0%, 25%, 50%, 75%, and 100% inclusion levels of BSFLM replacing
