Abstract
The paper describes a house for sow accommodation in which basic microclimate factors, dust concentration, ammonia concentration and number of bacteria and fungi in the air are analyzed. In the time of research here were 150 sows in the house. According to the obtained results the number of aerobic mesofilic bacteria was from 9.20x104 to 2.25x105 CFU/m3 of air, and the number of funghi from 8.12x103 to 1.25x104 CFU/m3 of air. Dust concentration was from 3.7 to 5.8 mg/m3. Most of the identified microorganisms were gram positive bacteria, then fungi and gram negative bacteria. Air concentrations of microorganisms and dust recorded in the sow house were according to the respective figures reported in the literature. Therefore it could be concluded that in modern accommodation conditions with automatic regulation of microclimate in the sows house, favorable microbiological air quality, could be expected whose values depend on population density and good management.
