Abstract

Studies have been carried out on the production of biogas from mixture of cow abdominal waste and its dung. The rate of biogas production and cumulative volume of the gas produced was compared with that of pure cow dung under the same experimental conditions. The result shows that the mixture of the cow abdominal waste and its dung started yielding biogas within 24hours. The pure dung started producing appreciable biogas after 7 days. The result further indicates that the cumulative volume of biogas produced was dependant on the amount of pure cow dung. The fresh and digested materials were analysed for percentage composition of C, N, P, K, total solids, volatile matter and ash content.
