Production and consumption aspects of biogas at farm enterprises of Ukraine were identified. Preconditions of negative changes in cattle farming were studied. The research done made it possible to evaluate production efficiency of both beef and alternative fuel – biogas – at farm enterprises. A polynomial model, which describes potential of biogas production in the years of 1990–2013 and envisages further increase of this indicator, was developed. It has been established that biogas production
