Options of Microclimate Optimization in Stable Objects with Respect to Thermal Comfort

The study was carried out at the farm in Petrovice. Dairy cows and heifers were included in the experiment. The relative humidity, temperature, cooling value environment and flow rate in stables were measured. The flow rate was measured by the handheld anemometer. The relative humidity and the temperature were obtained by the data logger with sensors. The cooling value environment was obtained by the psychrometer. The rectal temperature was measured simultaneously as further value. It was rated 3 different groups of dairy cows and heifers in 2 stables. The aim of this work was finding how this values impact thermal comfort of the animals. The temperature is the most significant factor because it is very variable value. The animals immediately react for change of this. All these measured values are important for optimal welfare of animals. They influence the productivity of dairy cows and heifers, milk quality, reproduction and health of animals
