In Mbarara District, smallholder farmers face challenges in accessing affordable protein sources for broiler chicken production. Housefly maggots are a cheap sustainable source of protein in broiler chicken production that smallholder farmers can employ to improve food security. This study evaluated farmers' awareness, access, and adoption of maggots as a protein source. A mixed-methods approach surveyed 130 broiler producers. Results show 71.5% of farmers are aware of maggot-based feeds, but only 6.1% use them, indicating a knowledge-application gap. Wealthier farmers were more likely to adopt this approach. To address this gap, the study recommends targeted media campaigns, educational initiatives, and demonstration projects showcasing economic benefits. Establishing local maggot production facilities, farmer cooperatives, and knowledge-sharing platforms could further support adoption.
