| This study presents the results of ensiling technology of the aboveground mass of corn both in pure form and with flat grain of soybeans or its green in order to provide canned fodder with digestible protein up to the zootechnical norm for high-intensity livestock farms. The study was carried out on the reclaimed lands of the Non-Chernozem zone on the basis of the livestock farm OJSC "Agrofirm Dmitrova Gora" of the Konakovsky district of the Tver region. They used the soybean variety of the northern ecotype with an indeterminate growth type - Okskaya. It was found that with flat soybean grain increase in silage by 1%, the yield of digestible protein elevates by 3.7% on average, and with the ratio of soybeans and corn by 8:92%, a complete supply of 1 feed unit with protein (106.5 g) is recorded. The yield of metabolic energy in the variant of experiment by 8:92%, where the feed unit reached the zootechnical norm in terms of protein supply, was practically the same in comparison with the preparation of silage from the aboveground mass of soybeans and corn in the ratio of 15:85% and amounted to 145.42 GJ ha-1 and 145.89 GJ ha-1 respectively. | ||
