Studying the problems of farm size in dairy farming are important and deal with them at this time may become a factor in overcoming the crisis in farming. Theoretical and practical questions about the size of holdings (rational, optimal, effective, efficient) are a constant focus of research in the context of accelerating the implementation of scientific and technological progress and innovation in the industry.
