Results of determination of yielding capacity, chemical composition of initial weight and silage quality of forages prepared from the binary mixtures of Japanese millet (Panicum curs-galli var. frumentaceum), millet (Panicum) and saccharine sorghum (Sorghum saccharatum) realized in the conditions of the Republic of Belarus were presented. Research results showed that the binary mixture of saccharine sorghum with blue lupine (Lupinus angustifolius) in ratio of 70% + 30%, respectively made it possible to obtain the highest efficiency (62,4 t/ha of green material, 15,1 t/ha of dry matter, 13,1 t/ha of fodder units). Mixed sowing of millet, Japanese millet and saccharine sorghum with blue lupine surpassed in productivity the single-crop sowing on 15,5-32,6%. It was established, that the silage produced from the mixture of sorghum and Japanese millet with lupine had higher energy and protein nutritive value: 0,86 and 0,98 fodder unit, respectively; 9,77 and 9,92 mJ of exchange energy per 1 kg of dry matter, respectively; 103, 3 and 108,4 grams of digestible protein per 1 fodder unit. High nutritive value and the best palatability of trial silos promoted the increasing of milk yield on 4,4-5,4% in comparison with the control tests. Haylage which was produced from drought resistant crops had high energy nutritive value: per 1 kg of dry matter there was noted 9,40-9,48 mJ of available energy, 0,89-0,94 fodder units with fodder unit provision with 102-114 grams of digestible protein

In the conditions of the Republic of Belarus there was realized comparative evaluation of chemical composition and nutritive value of silages produced on the basis of millet (Panicum) and maize (Zea mays), their productive action and economic efficiency of ensilage fodders in diets of young stock of cattle. Data of chemical analysis showed the benefits of millet silage. The content of crude protein, crude fat, carotene, calcium and phosphorous was higher in millet silage. The analogous situation was in the analysis of biochemical indexes and energy value of dry matter. As a result of application of millet silage in diets of young stock of cattle made it possible to obtain 3,7 kg of body weight gain, while the expenses of forage per 1 kilogram of of weight gain lowered on 0,34 centner of fodder units, or 3,6%. Prime cost of 1 centner of fodder units in a diet in experimental group was on 57,3% lower than in a control one. Thus, use of millet silage in diets of heifers made it possible to lower the cost of fodders per 1 kilogram of weight gain on 63,2%, and prime cost of 1 kilogram of weight gain – on 19,8%.

Japanese millet (Echinochloa frumentacea) growing and yielding capacity was estimated in single and mixed sowings cultivated on sod-podzolic light loamy soils in the conditions of the Republic of Belarus; as well as comparative evaluation of silage quality and determination of digestibility of nutrients. Field experiment with forage crops was realized in threefold replication in accordance with the following scheme: Japanese millet (100%); Japanese millet (70%) + vetch (Vicia) (30%); Japanese millet (70%) + lupine (Luoinus) (30%); Japanese millet (70%) + pea (Pisum) (30%); Japanese millet (70%) + soybean (Glycine max) (30%). Research results showed that mixed sowings of Japanese millet with bean cultures made it possible to obtain higher yields than single sowings on 5,9-15,6%. Silage made of Japanese millet with bean culture contained higher amount of crude protein on 2,73-3,98% in comparison with silage which was produces only from Japanese millet. Silage produced from Japanese millet mixture with high protein crops had high energy and protein value: 0,90-0,92 fodder units; 9,47-9,59 mJ of metabolic energy per 1 kg of dry matter and 102-103 g of digestible protein per 1 fodder unit

In the conditions of the Republic of Belarus there was studied the yielding capacity and quality composition of nontraditional high-energy crops (sorghum and Sudan grass hybrid; millet (Panicum); white panicum (Japanese millet)) as well as there was developed a technology fodder conservation. In course of the study there was analyzed accumulation of nutrients in accordance with crop development phases and their quality composition; also there was determined a method of application of grass stands of the studied crops for their production use. It is established, that the most suitable for conditions of Vitebsk region from high-quality cultures is sorgho-sudan-grass hybrid which reaches phases of seed formation and provides productivity of dry matter more than 9 t/ha with humidity of green mass of 69% that is optimum for preparation of tinned forage. Sugar sorgho and grain is reached by phases of ear formation and have provided productivity of green mass of 25,9-25,7 t/ha, dry matter - 3,5 t/ha. To use double-cut sorgho-sudan-grass hybrid on a silo less effectively as the received green mass has high humidity (92%), and the general gathering of dry matter twice more low, than at single-cut use. At single-cut use the culture reaches phases of grain formation in which contains about 31% of dry matter that is favorable for conservation. Double-cut use of sorgho-sudan-grass hybrid is comprehensible at its cultivation in the green conveyor to use as green top dressing during the pasturable period. Japanese millet is better to use double-cut as it has provided the maximum productivity of green mass of high quality (63,9 t/ha) and dry matter (9,1 t/ha), it is in 2,3 and 1,6% of time above, than at single-cut use. Single-cut crops of sorgho-sudan-grass hybrid are expedient for using as a component at siloing of galega orientalis. In an early phase of development (7-8 leaves) the new-mown green mass of sorgho-sudan-grass hybrid possesses toxicity on the bottom border of average degree, but in 2 hours after mowing the forage becomes not toxic. In later phase of development there is an accumulation of sugars, and new-mown mass of sorgho is nontoxical. Sorghum cultures contain high percent of non-decomposed protein - 58,3-84,6% that is very important in feeding of highly productive cows.
