[Dust emission from chicken and layer houses].
Dust concentration was measured by Laser-monitor in two at a time houses for layers with litter or with cages and in two at a time houses for growing chicken with litter or with cages in the middle of the keeping area, in the outlet opening and in 3, 10, 50 and 100 m distance over a period of 8 weeks in winter, summer and spring/autumn. Dust values have shown only less dynamics between 8 am and 5 pm. Significant positive correlation was found between dust concentration and age of poultry, keeping time resp. in litter housing system but not in cage housing system. Also, it was demonstrated a significant relation between dust concentration inside of poultry house, at the outlet openings and in 3 m distance in the outdoor air. There was no influence evident of indoor dust concentration on the dust value in the environment in more than 3 m distance to the poultry house. It was shown a low dust concentration of 0.1% up to 2.1%--compared to the indoor dust values--in 50 and 100 m distance to outlet ventilation system independent on housing, climatic and topographic factors.
