The purpose of research - development of models and techniques of creating and using specialized pastures for dairy cows with given parameters of yield, intensity of use, adaptability and nutritional value of feed that meet the physiological needs of this group of animals. The research work was carried out on the basis of the methodology and methodological aspects, which are widely used in the international scientific practice and comply with the requirements of ISO, including the widely approved methodological recommendations on carrying out scientific research in forage production and grassland learning and a new approach of evaluation of the productive action of vegetable raw materials and feed for livestock products in conventional dairy units. According to the task were carried out theoretical, field and laboratory studies, assessed the biological efficiency of pasture mixtures of perennial grassroots of clover and legumes, were chosen the best kinds for growing in joint crops that have productive longevity (more than 3 years) and observed similar parameters of the phytocenotic competition. Researches developed the principle of cyclic use of perennial pasture grasses with different intensity of growth of biomass, which in comparison with the traditional mode of grazing, increases the number of grazing cycles from 3 to 5-6 per season. Was tested model of cultural pastures for dairy cows adapted to the conditions of unstable moisture content of the soil and the technology of establishment and management of pasture for dairy cattle, based on the farming practices of cultivation at different times-maturing legume-grass mixtures, system of portioning grazing of cows and improved scheme of planned cyclic use of pastures for grazing season. Established that this technology provides in terms of right-bank forest-steppe continuous supply of pasture forage for 162 days with performance 4,16-4,57 t/ha of fodder units, the potential yield of milk from pasture 5,36-5,85 t/ha and the level of profitability 121-189 %. Area of application: scientific theoretical developments of NIR will be used by agricultural scientists and practical results will be implemented in the agricultural enterprises of different ownership forms, specializing in the production of milk.
