PROTEIN, ENERGY AND MINERAL NUTRITIONAL VALUE OF FEED IN DIFFERENT TECHNOLOGICAL SYSTEMS OF PASTURE MANAGEMENT

The results of studies substantiating the possibility maintaining high quality pasture forage during 46-year use grass stands are presented. feed was assessed by protein and energy nutrition, as well content mineral elements in different technological systems management (technogenic — without fertilizers, integrated against background P45K90, technogenic-mineral backgrounds N60–180P45K90–120, technogenic-organic 10 20 tons manure/ha once every 4 years). Experimental data were obtained on accordance with technical requirements GOST R 57482-2017 "Pasture feed", indicators which varied significantly depending system levels fertilizer. influence weather conditions nutritional value cycles herbage is substantiated using example 2016, characterized a dry growing season.
