Development of resource-saving directions in animal breeding on the basis of ecological and economic approaches

Presently situation in agriculture leads to significant environmental pollution, in particular, in cattle breeding. The storage of manure significantly worsens the sanitary and epidemiological situation. In this connection, the article proposes the use of biogas plants for cattle breeding as an environmentally safe direction for the manure utilization with high economic efficiency. Particular attention is paid to the criterion of investment efficiency after use of a biogas plant, taking into account prevented environmental damage from manure storage. An economic feasibility study of manure utilization schemes is carried out using both a biogas plant and without it, taking into account environmental and economic efficiency.
