The aim of the Project was to evaluate the keeping ways (1st - on summer in pasture, on winter in stable and 2nd around the year in stable) and different feeding influence on dairy cows health and productivity. To ensure animals good health status by its keeping in 1st and 2nd ways the cows right feeding technology choice and optimum keeping conditions are essential. At the beginning of trial by using mixed feed in 2nd variant there was increased acetone body level in the milk of 15 % of total number of cows. After 5 months acetones bodies were ascertained in milk of 20 % of cows. We consider, that feeding out cut silage or haylage from big bales, where protein content is comparatively high, causes misbalance between protein and carbohydrates as well as sugar deficiency that resulted in acetone body increasing in organism. Health condition of cows legs claws improved essentially (p is less than 0.01) and only 1 animal diseased in average at the month per herd. Disease with clinic mastitis at the end of 1st period decreased essentially (p is less than 0.01). By comparing artificial insemination data on the years 2006 - 2007 it is seen that average pregnancy percentage in the year 2007 is by 5.4 % higher than in the year 2006. The conditions of a new keeping and feeding way (2nd variant) promote to maintain good animal health, active metabolism and improve potential producing ability expression in higher milk yield way.
