The aim of this thesis was to evaluate the effect of environmental changes on longevity and milk production of cows Czech Fleckvieh cattle in selected breeding. The work focused on the comparison parameters milk production, longevity reasons decommissioning cows and lactation on which the cows were excluded. Within one company were monitored two groups of cows. The first group of cows was monitored in the original stabling. The second group consisted of pregnant heifers whose milk production have been monitored in subsequent years. They were removed to new stabling among cows of Holstein cattle. Each of the groups had different environmental conditions, treatment and different feed ration. Milk production and longevity of cows were evaluated in six years. In the framework of the obtained results it can be concluded that the change in the environment, treatment and feed ration were the main reason leading to the increase in the milk production of cows in the new location. Cows in the new stabling were mostly eliminated because of the reproductive disorder, milk production and other reasons (mortality, high age, diarrhea, poorly developed teats, bad condition).
