Analysis of Russian production machines for fodder preparation and distribution in the cattle houses showed their obsolete and energy consuming construction. Thus, it appeared an urgent task to design and develop the modern machines and technological lines, fitted with technical solutions limiting costs of animal production through increasing the efficiency, reducing labour and energy consumption, saving electric energy and raw materials. The basic developed and implemented machines are as follows: a double-drum cutter-grinder with the constainer rotating round vertical axis, a cutter for cylindrical hay/straw bales with horizontally rotating container, a machine for dry cleaning root crops, grinder-feeder for root crops, a mobile cutter-distributor for roughages, grinder-mixer with two reciprocally rotating drums for grinding roughages and sappy feeds. The energy consumption by the feed preparation line using energy saving technology and equipped with newly designed machines was by 40% lower in comparison to traditional KORK-15 feed preparation plant. The economical effects of practical application of newly developed and implemented technical means were as high as 8.4 million roubles (according to 1990 prices).
