Sažetak
Hygienic air quality in swine facilities is one of the basic health and production factors. The aim of this investigation was to determine the number of airborne mesophilic bacteria and fungi in particular technological phases of production, by monitoring of common microclimatic parameters. Researching was conducted in the farrowing stable of 185 m2 with 28 farrowing pens, nursery stable of 47 m2 with 12 one floor cages and fattening stable of 167,5 m2 with 14 pens. During investigation there were placed in farrowing stable 25 sows with litter in average, nursery stable 215 piglets and in fattening stable 190 pigs. The measurements were taken at 6 occasions during spring-summer period. According to the obtained results of number of airborne mesophilic bacteria in facilities, the highest mean value of 8,20 x 105 CFU/m3 of the air, was determined in nursery stable. This value was significantly higher according to their number in fattening stable. The highest mean value of fungi of 1,61 x 105 CFU/m3 of the air was also determined in nursery stable, but there was no significant difference according to their number in other production phases. The reasons of such values can be non-adequate animal density per unit of housing space as well as effusive air humidity which were determined during researching in nursery stable.
