Abstract
The measurement of temperature, humidity and dew point in the selected stable, and for the comparison also in the courtyard, took place continuously from 1.4.2011 to 31.3.2012. Because of its technical demands, the measurement of stable gases took place roughly 1x in a month and that in the 24 h cycle. This work should answer the questions, how much is the stable microclimate dependent on the ambient environment - current weather, whether there are suitable conditions in the stables of National Stud-Farm in Kladruby nad Labem with respect to the welfare of horses, how much is the concentration of stable gases in enclosed areas according to the presence of horses changing and, possibly, how much affects the horse breeding the environment.
