This study evaluated the bio-fertilizer quality of digestate obtained from the anaerobic co-digestion of laying birds and broiler droppings in a 50:50 ratio. The study's objectives were to ascertain the bio-fertilizer quality (N, P, K, Mg, and Ca) of laying bird and broiler (50:50) droppings before anaerobic co-digestion of the substrate and evaluate the impact of the anaerobic co-digestion process on the biofertilizer quality of the digestate and substrate. The initial measurements of the substrate showed the following values: pH (6.9), temperature (29.03°C), nitrogen (0.28%), phosphorus (2.01%), potassium (2.58%), magnesium (0.68%), and calcium (3.01%). After the anaerobic co-digestion, significant changes were noticed. The result showed that the pH increased by 4.3% to 7.2, while the temperature rose by 10.9% to 32.20°C. Nitrogen concentration was reduced significantly by 70.0% to 0.09%, whereas phosphorus declined by 32.8% to 1.35%. The potassium content was reduced by 23.6% to 1.97%, magnesium by 11.8% to 0.60%, and calcium by 7.0% to 2.8%.
