Hungary is located in Cenlral-Europe in the continental climate zone. Average annual precipitation is 580 mm wich makes the climate quite arid Distribution of precipitation is not even neither from geographic nor from chronologic aspects. This latter fact led to the present production structure being different from region to region within the country. Green yields of pastures show a different pattern during the vegetation period. Main features and advantages of technology developed by PAU team for grazing- based utilization of river valleys are the following: - grass yield is converted into marcetable product; - milk production is based on intesively farmed grasslands; - annual bulk feed (hay, haylage, silage and green feed) consumption is covered by grassland yield; - mobile milking, drinking hay- and concentrate feeding; - handable units of 120-150 cows; - seasonal calving in February, March and April; - artificial insemination; - round the clock grazing for 6-7 months; - using intesive milk type breeds; - closed, deep litter, loose keeping in winter; - low investments, high revenues.
