The information on the anaerobic fermentation of the livestockfarm wastes is presented in the article. It is established that in the fermentation of cattle manure with the layer inclusions the biogas output is on average 10,32 % higher compared with other substratetypes. The optimal for the fermentationthe substratelinear particle size is 30-35 mm, the introduction of the catalyst FeSO4 in the doseof 0,25 % from the fermented substrate weightaccele-rates thegas generation process.
