ISSUE FOCUS 28 Alternative Proteins Magazine April 2025 “The poultry industry faces increasing pressure to enhance sustainability, improve animal welfare standards, and maintain production efficiency. Black Soldier Fly Larvae offer a multifaceted solution addressing these interconnected challenges. Their adoption is accelerating across diverse production systems—including broiler, layer, organic, and free-range—supported by accumulating scientific evidence and growing commercial availability.” BSFL: BETTER HEALTH & WELFARE FOR POULTRY Thomas Stringer CFO and Co-Founder Flybox® Black Soldier Fly Larvae (BSFL) offer a sustainable feed solution that supports poultry gut health, strengthens immunity, and promotes natural behaviours. Rich in functional nutrients like lauric acid, they enhance flock resilience while reducing environmental impact. Now adopted globally, BSFL signal a smarter, welfare-focused approach to poultry nutrition. INSECT PROTEIN IS NO LONGER NICHE A significant development is under way in poultry nutrition. Around the world, feeds derived from BSFL are being adopted by smallholders and commercial producers alike. The reasons are clear: BSFL offer a powerful combination of nutritional value, functional health benefits, and environmental sustainability. From Europe to Africa and Southeast Asia, BSFL are becoming an increasingly viable alternative to conventional protein sources like soy and fishmeal. They provide producers with greater feed autonomy, improved animal welfare outcomes, and a reduced environmental footprint. As regulatory frameworks evolve and supply chains expand, BSFL are shifting from niche ingredient to mainstream nutritional solution. BUILT FOR BIRD HEALTH: WHAT MAKES BSFL UNIQUE Black Soldier Fly Larvae are naturally suited to poultry nutrition, offering a dense and digestible protein source with functional properties that go far beyond basic growth support. Their protein content typically ranges from 40 to 50 per cent, boasting a robust amino acid profile that includes lysine and methionine—essential building blocks for muscle development, feather quality, and egg production. Lysine supports muscle protein synthesis, while methionine plays a vital role in feather formation and metabolic processes. Compared to conventional protein sources, BSFL generally offer a favourable lysine profile and competitive methionine levels, although precise diet formulation considering inclusion rates and bird requirements remains essential.
