Sažetak
In the present study, air quality in a cage-housed laying hen house was investigated throughout the seasons by assessing dust and endotoxin concentrations. Measurements were done twice a month during the 1-year production cycle. The mean levels of dust and endotoxins ranged from 0.60 mg/m3 in May to 2.83 mg/m3 in November, and from 203.15 EU/m3 in August to 745.53 EU/m3 in April. Significantly higher concentrations of dust and endotoxins in the poultry house were determined in the autumn and winter seasons, and endotoxins in the spring season as well, compared to the summer (P<0.05 all). The results suggested that the cooler periods of the year pose a greater risk for the welfare and performance of laying hens, but also for the health of humans working in these settings in terms of the levels of airborne dust and endotoxins.
