Abstract
Production of biogas in batch digesters at 30°C from sheep droppings produced 93 l gas/kg dry matter whereas cattle dung yielded 234 l/kg dry matter. When the sheep droppings and cattle dung were used at 25:75 (w/w), gas production per kg dry matter was equal to that of cattle dung only. The methane content of the biogas obtained from sheep droppings was 70 to 72% as compared to 56 to 60% from cattle dung.
