Published by Elsevier Ltd. Fermented cow dung as raw material can be used for biogas generation from cattle ditch bottom sludge inoculum. In a small homemade device, cyclical experiments have been conducted to study the effects of temperature and concentration of the material on cow dung anaerobic fermentation and gas production. The results show that at lower temperature fermentation methane gas production as feed concentration increases. With increasing temperature, the concentration of the biogas changes as well. When the concentration is about 7%, the optimum temperature of biogas fermentation is 34 °C, with a total gas production of 2290ml and 2594ml. When the concentration is 10%, the biogas fermentation optimum temperature is 40 °C, and the total gas production is 3757ml. The research will provide a preliminary result for further studies in this area.
