Black Soldier Fly Larvae as a Sustainable Protein Source in Broiler Production: Performance, Health, and Environmental Impacts
June, 2025, Bio Cycle Labs
Black Soldier Fly Larvae (BSFL; Hermetia illucens) are emerging as a viable alternative protein source that aligns with both performance targets and environmental goals.
The global poultry meat industry continues to expand in response to rising protein demand, particularly in emerging markets. However, broiler production systems face increasing challenges: feed price volatility, sustainability pressures, and regulatory shifts toward antibiotic-free and environmentally conscious farming.
Nutritional Composition of BSFL
BSFL are rich in nutrients essential for rapid broiler growth and feed conversion efficiency:
The inclusion of BSFL meal in broiler diets (typically 5-20%) has been extensively studied and shown to maintain or improve growth performance, feed intake, FCR (Feed Conversion Ratio), and meat quality.
- Crude protein: 35-50% (dry matter), with a complete amino acid profile;
- Fat content: 15-35%, including high levels of lauric acid (C12:0);
- Minerals: Calcium, phosphorus, magnesium, trace elements;
- Bioactive compounds: Chitin, antimicrobial peptides, and medium-chain fatty acids.

Health and Welfare Benefits
BSFL not only support growth but also offer natural immune-boosting effects, attributed to:
As such, BSFL can play a key role in antibiotic-free production systems by enhancing disease resistance through nutritional means.
BSFL not only support growth but also offer natural immune-boosting effects, attributed to:
- Lauric acid, which has strong antibacterial activity against gram-positive pathogens such as Clostridium perfringens;
- Chitin and chitosan, which may act as prebiotics, stimulating beneficial gut microbiota;
- Reduction in enteric diseases and inflammation, leading to improved intestinal integrity and lower mortality rates.

Environmental and Economic Impact
From a sustainability perspective, BSFL offer a low-footprint protein production pathway:
These systems support EU Green Deal goals and global climate-smart agriculture frameworks.
From a sustainability perspective, BSFL offer a low-footprint protein production pathway:
- Lower greenhouse gas emissions and land use than soy or fishmeal;
- Upcycled organic waste: BSFL can be reared on pre-treated food waste, agri-residues, or manure;
- Frass (larval residue) serves as an organic fertilizer, rich in nitrogen and phosphorus;
- Feed cost savings: With appropriate local waste inputs, BSFL protein can reduce feed costs by up to 30-50% over time.
These systems support EU Green Deal goals and global climate-smart agriculture frameworks.
At BioCycle Labs, we provide modular BSFL production systems that integrate into existing poultry meat farming operations:
These systems are ideal for medium to large-scale producers, contract growers, and vertically integrated poultry operations aiming to boost resilience and sustainability.
- On-site rearing modules: Designed for farms producing or accessing organic waste;
- Waste preprocessing units: Ensuring hygienic, nutrient-optimized BSFL substrate;
- Post-harvest processing: Drying, grinding, and integrating insect meal into feed rations;
- EU-compliant system design, aligned with Regulation (EU) 2021/1372.
These systems are ideal for medium to large-scale producers, contract growers, and vertically integrated poultry operations aiming to boost resilience and sustainability.
Application in Broiler Operations
Numerous studies across Europe and Asia have confirmed that BSFL can replace 25-100% of fishmeal and up to 50% of soybean meal in broiler diets without compromising:
With rising demand for sustainable meat, insect-fed poultry is gaining traction in premium and ESG-driven retail segments, making this innovation not just a nutritional strategy, but a branding opportunity.
BSFL-based protein aligns with the triple bottom line of modern broiler farming:
1) Performance,
2) Sustainability, and
3) Innovation.
The next era of poultry farming is here - and it’s insect-powered.
- Growth rates and feed efficiency;
- Carcass yield and meat quality (including moisture and tenderness);
- Animal welfare and mortality rates.
