Abstract Livestock breeding in Uzbekistan is established mainly small farms, and more than 80 percent of the total product produced them. With development animal husbandry there a demand for equipment used preparation feed, including concentrated feed by crushing grains. Taking this into account, small-sized grain grinder device grinding grains was developed farms. The height 1170 mm, length 50...

One of the essentials of the method was the use of a horn spoon in spreading the moisture or soil films uniformly throughout the rather dry soil mass. When plant tissue is finely cut in a grinder, relatively few of the cells are actually opened. The impo...
