Özet:

 The purpose of the study was the impact of different types of ventilation systems in boars pen on the microclimate and their physiological parameters. The control group of boars was kept in a house with a transverse ventilation system, and the animals of the experimental group were kept in a geothermal air supply. It was found that, regardless of the season, transverse ventilation provides a significantly higher air velocity and relative humidity: in Winter - 0.15 m s1 and 5.4; in Spring - 0.35 m s1 and 5.3; in Summer - 0.41 m s1 and 0.7; in Autumn - 0.28 m s1 and 8.1. Maintaining a stable temperature by the normative values in the boar housing was due to geothermal ventilation, regardless of the season, especially the basement effect was observed in the summer months, where the air temperature was cooled to 4.5C P  0.001, compared to the transverse ventilation system. Compared with the boars in the experimental group, under the influence of the temperature increase in Summer, the boars in the control group increased significantly the respiratory rate to 50.9 ppm P  0.001 and heartbeat rate of 45.7 ppm P  0.001. An increase in rectal temperature in boars at elevated ambient temperature under both air ventilation systems was not found. The obtained results make it possible to introduce the use of cost-effective geothermal air supply technology in pig farms to harmonize the physiological parameters of boars to meet their biological needs, even in closed housing to improve their welfare.
