In the process of research, the temperature and the contents of moisture, oxygen, carbon dioxide and ammonium hydrate were measured diurnally above the pigs pen. To measure these parameters, the appropriate sensors, connected to ALMEMO Data Logger 8990-8 were used. The PC AMR Win Control software was used for the saved data processing. The results of research given in the article are about inner climate parameters in three pigsties which use different pigs breeding technologies. The measurements were carried out at 1.5 m high above pig's pen diurnally in spring and summer. As a result of the research it was found that the parameters of air temperature (13.2...24.5 deg C) were under permitted limits in spring and summer. The parameters of moisture exceeded permitted limits in spring (75.0...87.4 per cent). The content of hydrate was extremely critical in spring 30.5...35.2 ppm. At the summer time the situation improved, because of opened doors or windows, but reached to 48.8 and 58.0 ppm in the farms No 1 and 2, where respectively the dung scraper and chain scraper conveyer were used
