Anaerobic fermentation of mink manure and cow manure was investigated to estimate the volume and quality of the biogas produced. The process was performed in 4 batch reactors at the temperature 37 deg C. The average biogas or methane yields were 303 l kgvsd E-1 or 168 l kgvsd E-1 obtained from a substrate of cow manure with inoculum 25 %. The investigated average biogas or methane yields from mink manure with inoculum 25 % were 730 l kgVSd E-1 or 512 l kgVSd E-1 respectively. The average methane content was 56 % or 70 % in biogas from cow manure or mink manure during the anaerobic fermentation process.
