FIGHTING ANTIMICROBIAL RESISTANCE WITH INSECT-BASED LIVESTOCK FEED

FIGHTING ANTIMICROBIAL RESISTANCE WITH INSECT-BASED LIVESTOCK FEED

Why in the News?

• Emerging alternative: Insect-based feed offers a cost-effective and sustainable solution for livestock nutrition, contributing to sustainable livestock feeding practices.
• Government initiatives: ICAR is promoting insect-based feeds through MoUs with industry players like Loopworm and Ultra Nutri India, demonstrating a commitment to policy development in this sector.
• AMR challenge: Excessive use of antibiotics in livestock farming is fueling antimicrobial resistance (AMR), threatening public health and necessitating the exploration of alternative protein sources.

Risks of AMR in Livestock Farming

• Antibiotic overuse: Livestock farming uses half of global antibiotics, projected to rise 53% by 2030, highlighting the urgent need for sustainable livestock feeding practices.
• Public health threat: AMR could cause 10 million deaths annually by 2050, emphasizing the importance of developing functional feed additives as alternatives.
• Environmental spread: Antibiotic residues contaminate soil, water, air, increasing human exposure and potentially disrupting ecosystem services.
• Regulatory gaps: In LMICs, unregulated use of antibiotics like chloramphenicol persists, risking serious diseases and underscoring the need for robust policy development.

Benefits of Insect-Based Feed

• Nutrient-rich: Insects offer high-quality proteins, fats, and micronutrients like zinc and iron, making them excellent alternative protein sources.
• Eco-friendly: Rearing insects requires fewer resources and emits lower greenhouse gases, contributing to climate change mitigation. A life cycle assessment of insect farming demonstrates its positive environmental impact.
• Efficient production: Insects transform organic waste into high-grade proteins faster than traditional feed, showcasing superior feed conversion efficiency.
• Cost-effective: Better digestibility and low production cost make insect feed viable for sustainable farming, with bsfl meal (black soldier fly larvae) being a popular option.
• Global acceptance: 40 countries now regulate insect-based feed, showing its growing global acceptance as a sustainable solution for livestock nutrition.
