Replacement of manufacturing of hay by use soy chaff in farm animals feeding

After harvesting soybean by the method of Stripping remains a by-product-soybean floor, which can be used as fertilizer, and in case of lack of feed resources - as coarse feed to meet the needs of livestock in providing complete feeding of farm animals. The relevance of the use of the floor is caused not only by the need to increase the productivity of the livestock industry but also by lower costs of its production compared to hay and straw. The results of the study indicate that the nutritional value of 1.7 tons of the floor obtained from 4 hectares of soybean field corresponds to the main similar characteristics of 1.7 tons of grain hay obtained from one hectare. Currently, in the Amur region, soybeans are grown on 900 thousand hectares, which can compensate for sexual fodder production of 380 thousand tons of hay, which requires at least 220 thousand hectares of hayfields. With the number of cattle within 100 thousand heads, including 50 thousand cows, the need for hay is about 200 thousand tons, for the production of which it is necessary to 110 thousand hectares of acreage from the available 280.6 thousand hectares of hayfields in the region. In this regard, studies of Far Eastern research Institute of mechanization and electrification of agriculture the development of the technology of harvesting soybeans by the method of Stripping remains are relevant and necessary to optimize the economic condition of agricultural production.
