ABSTRACT:
The purpose of the current study was to investigate pollution of various technological zones in uninsulated and insulated cowsheds with ammonia and microorganisms. The study showed that there were different levels of pollution in various technological zones of cow houses. Regardless of cowshed type (uninsulated or insulated), the intensity of ammonia emission from floor surface was highest in the zones of manure handling and keeping places (22.5–52.6 mg/m2/h) compared with feed delivery zones. Ammonia concentration and total amount of microorganisms in the air was higher in insulated (3.5–4.6 ppm and 53.8–141.8 thous./m3) than in uninsulated cow houses (0.6–2.8 ppm and 19.1–61.7 thous./m3).
