This study was performed to define the effects of the cattle feces on aerobic composting of food wastes in vessel system. Weights of cattle feces added to food wastes of 3 kg were 0.25, 0.50, 1.00 and 1.50 kg, respectively. Reactors were operated with stirring for 1 hour per day by 1 rpm and aeration for 2 hours per day. When the weight of cattle feces was increased, the highest temperature of sample was increased, the duration period of higher temperature was elongated, and the fluctuation of pH was severe. When the weight of cattle feces was decreased, the final density was increased. The more cattle feces were added, the more porosity was increased, C/N ratio, salinity and conductivity were decreased. These facts denotes that the addition of cattle feces increases the efficiency of composting process and the final product of composting, namely compost.
