The overall objective of this work is to evaluate the energy potential of biogas inputs (chicken manure and pig poop) with a view to their value. The research determined the physicochemical composition, the amount of biogas produced per day and the average. For hen dung, humidity (28.47%), DM (dry matter) (71.53%), OM (organic matter) (67%), density (270.77 kg/m³), carbon content (39.7%), nitrogen content (2.55%) and C/N ratio (15.23) and pig pork, moisture (47.98%), DM (45.6%), OM (23.55%), mass volumic (693.12kg/m³), carbon (38.88%), nitrogen (1.82%) and C/N (11.26). These results compared to those of the literature revealed a very good coincidence. Two experiments on the methanation of these inputs were carried out, the anaerobic digestion lasted 24 days, in a temperature range of 24 to 30 °C (mesophilic range). It was obtained for: hen dung 0.02526m³ and pig poach 0.00841m³ and on average the daily specific production of biogas of different substrates is: pork dung (0.00407m³/day) and the hen dung (0.00108m³/d) at an average temperature of 24°C.
