Mil'ko D. Mechanical and technological basis for technical systems provide fodder development for dairy farms

The thesis is devoted to development of foundations of technical systems provide fodder by improving processes harvesting plant material to improve the quality of the resulting feed product. The application of the proposed technical tools will reduce the loss of nutrients in plant material during storage and provide the industry agro production in the country high-performance, high-tech, energy-saving and environmentally friendly units. The validity of this provision confirmed the results of theoretical and experimental studies of physical - mechanical properties of plant material, energy, operational - technological parameters of the unit and line for loading plant material to polymeric storage with the introduction loose preservative configured in accordance with practical recommendations on the choice of circuits design parameters and operating modes. The proposed technology guarantees the price of 1 feed units - from 0.86 to 1.0 uah./f. units. Using the proposed production line in harvesting hay provides the weighted average cost of 1 f. units. of daily ration for feeding cows - 1,92 uah. Reducing the cost of milk when using this technology compared to other options range from 11.0 to 20.9%.
