The best pasture performance (61.2 t/ha of green mass, 14.42 t/hectare of dry matter, 11.6 t/ha of feed units) provided paiza in the phase of milky-wax ripeness is ascertained. Binary mixtures surpassed homotypical ones in pasture performance for 14,5-36,8%. Ensilage of paiza with lupine had high energy and aleyronic feeding power: 9,77 MJ of metabolizable energy in 1kg of dry matter, 0,86 feed units, 123.3 g of digestible protein per 1 feed unit. Economic effect per one cow for experimental period at feeding of ensilage of paiza with lupine made up 29.5 thousand roubles. Considering the big potential possibilities of high-energy nonconventional crops, on the one hand, absence of scientifically proved recommendations on technology of preparation of silage from them in the conditions of the republic, on the other hand, at the present stage the necessity for studying of the (know-how) and preparation of high-energy forages for large horned livestock on a basis of paiza and millet and their mixture with bean crop (lupine) has appeared. The purposes of research were: definition of efficiency and studying of change of chemical compound of nonconventional crops in process of their development; a comparative estimation of silages; definition of nutrients digestibility; productive action of silages; efficiency of use of silages in diets of lactic cows. Results of scientifically-economic experience are stated. During experience it was stated that animals received the economic diet in which clover-timothy silage was used as the basis. In the first skilled group it has been replaced with silage made from paiza with lupine, in the second - from millet with lupine. It is established, that daily average yields of milk at cows of skilled groups were above on 4,4 - 5,4% in comparison with the control. At recalculation on 4% milk the yield of milk in skilled groups has made: in the first (paiza + lupine) - 20,8 kg/head a day, in the second (millet + lupine) - 20,3 kg/head a day, that on 6,8 and 6,3% above in comparison with control group
