Г. В. Благовещенский The presented materials are based on the research results obtained by the European Grassland Federation (EGF) and presented at the 26 EGF General Meeting held in Norway in September 2016 as well as on other studies recently performed in European countries. The Meeting paid its main attention to the development strategy of sustainable production of high quality ruminant animal products under changing climatic conditions of Europe. It is shown that grassland-based dairy systems can produce up to 2 kilograms of animal protein per lkilogram of edible plant protein consumed by cows. The authors also prove that the intensification of ruminant production systems is based on high amount of maize silage and concentrates consumed. The paper highlights the innovations in forage production in agroecosystems, further improvement of forage production based on feed enrichment with legumes, and offers opportunities of distance control of gathering data on the productivity of agrocenoses and their assessment in a digital format.
