Abstract

This study piloted an integrated circular farming model that combines broiler chicken production with organic manure development at a purposively selected household in Ruswiga Village, Kagadi District, Uganda. A hybrid poultry house was constructed using semi-permanent and permanent materials to balance cost efficiency and durability. Over a period of 12 months, seven broiler brands were reared and assessed for growth, mortality, disease resistance, yield, and economic returns. Royalchick consistently outperformed other brands, achieving the highest growth (up to 2.0 kg/bird), and greatest profitability (UGX 2,000,000), while Ugachick recorded the weakest performance. Poultry droppings were composted into an organic manure prototype with a standardized nutrient composition (1.5-2.0% N, 1.0-1.5% P₂ O₅ , 1.0-1.5% K₂ O) and enhanced organic matter content. Field trials demonstrated high yield improvements in maize (300 kg/manure plot vs. 200 kg/ control plot), cassava (180 kg/manure plot vs. 100 kg/control plot), and beans (95 kg/manure plot vs. 56 kg/control plot), alongside improved soil fertility indicators. While the study results suggest improved economic viability of Royalchick and field manure-linked crop yields, statistical testing was not performed to confirm whether the observed differences were significant. To strengthen adoption, the project introduced unified branding under Sachrifam, marketed as Sachrifam Delicious Chicken and Sachrifam Organic Manure. Stakeholder engagement and farmer linkages ensured steady raw material flows and community ownership. The results propose that poultry-manure circular farming enhances productivity, soil fertility, and income generation, while branding and scale up strategies position Sachrifam as a sustainable enterprise capable of meeting local and regional demand.​
