Context: Indian researchers and ICAR institutes are scaling up insect-based livestock feed to combat antimicrobial resistance (AMR) and lower the environmental impact of conventional animal farming.
About Insect-Based Livestock Feed:
• What it is? Feed prepared from nutritious insect species such as black soldier flies, crickets, mealworms, and grasshoppers, used as a sustainable protein source for livestock and aquaculture.
• Feed prepared from nutritious insect species such as black soldier flies, crickets, mealworms, and grasshoppers, used as a sustainable protein source for livestock and aquaculture.
• Developed by: Pioneered by ICAR and private partners like Ultra Nutri India, Loopworm, and Bhairav Renderers in collaboration with institutes such as CIBA and CMFRI.
• Principle behind working: Waste-to-protein bioconversion: Insects like black soldier fly larvae efficiently consume and metabolize organic residues (agro-waste, food waste, brewery waste), producing high-protein biomass suitable for animal feed. Rapid biomass accumulation: Larvae grow rapidly (within 12–15 days), accumulating up to 75% crude protein and essential lipids, making the conversion process time-efficient and cost-effective. Enhanced gut microbiota modulation: Insect-derived proteins enhance animal gut health by promoting beneficial microbiota and reducing dependency on antibiotic growth promoters—thus helping mitigate AMR. Closed-loop nutrient cycling: Residual frass (insect waste) can be used as organic fertilizer, creating a circular, low-waste production model that supports sustainable agriculture.

• Key Features: High nutritional value: Rich in proteins (up to 75%), fats, micronutrients (zinc, iron, calcium), and dietary fibre. Efficient resource use: Insects require less land, water, and feed compared to traditional livestock farming. Low environmental footprint: Emissions of greenhouse gases are significantly lower in insect farming. Waste valorization: Insects upcycle organic and food waste into usable animal feed. Economic viability: Lower cost of production with better protein digestibility than soy or fish-based feed.

• Significance: Fights AMR: Reduces the need for antibiotics in feed, helping tackle antimicrobial resistance at the source. Supports food security: Can help meet rising protein demands as global food production must grow 70% by 2050 (FAO). Enhances climate resilience: Aligns with climate-smart agriculture and helps reduce the environmental impact of animal farming. Global momentum: Already regulated in 40 countries for animal feed use, including species like black soldier flies and crickets. Indian initiatives: ICAR-led projects aim to scale insect-based feed for shrimp, seabass, poultry, and livestock.
