Most work has been done to increase bioavailability of feedstock material to anaerobic bacteria. Those works were concentrated mostly on physical, biological, ultrasound and chemical pre-treatment. The aim of this work was to determine the effect of thermal pre-treatment on biogas production. Poultry droppings and Pig dung were used as feedstock. The two feed-stocks were pre-treated with temperature of 90°C and 105°C. The biogas and methane yield were determined using volume displacement method. It was observed that methane yield increased for the two different temperatures but methane yield was higher at 105°C and the untreated feedstock had lower methane yield.
