Sažetak
Research was conducted in piggery on an industrial breeding farm and on a family agricultural husbandry. Basic microclimate factors, air temperature, humidity, air velocity, lighthing, ammonia and carbon dioxide concentration were determined as well as the bacteria and fungi content in the air. Measuring was done during two spring months, on five spots along the central hall, in animal biozone.
The obtained show a statistically significant difference in bacteria and fungi number between two housing systems. In intensive housing from 1.19x10³ to 6.04x10³ CFU/m³ bacteria, and from 0.04x10² to 1.43x10² CFU/m³ fungi were found. At the same time in the air of the family husbandry pig house bacteria numbered from 16.80x10³ to 33.60x10³ CFU/m³. Fungi numbered from 1.10x10² to 4.80x10² CFU/m³.
