This study investigated daily and cumulative production of biogas from three different manure; poultry dropping, pig dung and cow dung. 3kg of each of the dried dungs was mixed simultaneously with 16 litres of water in three 20 litre biogas digesters constructed for the experiment simultaneously to give a 0.19kg/litre slurry volume of biomass each. The biogas yield was measured for 30 days on daily basis using water displacement method at ambient temperature variation of between 280C and 320C. It was observed that the production of biogas did not start for all the three manure until the 4th day. After which, it increased and got to the peak on the 13th day for poultry manure, 14th day for pig manure and 12th day for cow dung. From the comparative analysis of the biogas production from the three manure, results obtained indicated that manure from poultry, pig and cow, gave average daily yield of 38.67ml, 34.17ml and 26.00ml respectively while a cumulative value of 1160.00ml, 1025ml and 780ml respectively were also recorded for 30 days’ retention period. These results show that the three manure used are excellent biomass materials.
