Sažetak
The aim of the study was to determine fungi count in a dairy barn and its immediate environment and to help establish borderline values in line with EU recommendations on airborne emissions from animal housing. A Merck MAS-100 air sampler was employed with respective nutrient agar for the capture, incubation and counting of airborne fungi. Air temperature, relative humidity and air velocity were simultaneously determined by a Testo 400 device. Air sampling was done once a week in the morning (at 7:30), in the middle of the day (at 12:30) and in the evening (at 18:30), during two autumn months. Within the barn, measurements were performed in the animal housing area along the feedlot and outside the barn at a distance of 5 m, 25 m and 50 m, downwind and upwind from the barn. The mean values of total airborne fungi count in the barn air were 5.85×104 /m3 in the morning, 5.52×104 CFU/m3 at noon, and 6.01×104 CFU/m3 in the evening. The fungi count
showed a statistically significant decrease as close as 5 m to the barn (P<0.05). The microclimate parameters measured in the barn were within the standard values for dairy barn indoor atmospheres.
