Negative effects of high temperatures on cattle milk production is a specific problem. Dairy-cows, who produce much more heat than cows that are not milked, are more susceptible to high temperatures of the surrounding environment than other cattle. Changes in temperatures and atmospheric pressure were monitored throughout a year and then its influence on the milk production of cattle has been evaluated. It has been discovered that low temperatures do not have any significant influence on dairy-cows. However, at high temperatures dairy-cows suffer from heat stress and it leads to lower volumes of the daily milk production. The Holstein breed showed a higher sensitivity to temperature fluctuations than the Czech spotted breed; however, the Holstein breed milk production is better balanced in a long run (a year period).
