The results of the assessment of the temperature-humidity regime in the modern uninsulated barn in the summer period with external temperature fluctuations from +16.6°Ði to +37.2°Ði are presented. It was established that the indoor climate was significantly related to the state of the environment (r=0.95; p<0.001). Significant differences were found in terms of the temperature-humidity index (1.6–5.1 units) in different parts of the building, which may affect the state of comfort of the animals. The use of additional (except natural) ventilation in order to normalize the air environment should be carried out taking into account the time of day and the area of the room.
