A study of the farm factors was conducted in three buildings used for farming dairy cows. They were kept free in individual boxes or as a group living on deep litter bedding. Two of them were open and the third was closed structure. The average monthly and seasonal values of temperature, humidity and air movement were calculated. It was found that temperature, humidity and air movement in the buildings depend on the season, type of building and environmental factors. The daily thermo-hygrograms made during typical summer and winter days show the actual state of the farm factors in the buildings. The topographical distribution of floor temperatures in open buildings, compared to closed ones, confirmed their higher degree of dependence on ambient temperatures. The results were statistically processed using IBM, SPSS-21.
