| Abstract: | "1. The aim of the present study was to estimate gas concentrations in commercial turkey houses by Fourier Transform Infrared Spectroscopy (FTIR). 2. The experiment was conducted in 5 buildings of a commercial turkey farm. The measurements of gases were carried out every 3 weeks of the growth cycle. 3. The results demonstrate that ammonia and carbon dioxide are the prevalent gases released during the entire production cycle in turkey houses. The mean concentrations of the above compounds ranged between 4-31 ppm and 220-2058 ppm, respectively. Thiols, nitriles, amines, aldehydes, hydrocarbons and other organic and inorganic compounds also occurred in turkey houses, but they were emitted periodically and their mean concentrations were significantly lower in comparison with CO2 and NH3. 4. Lower ventilation ratio and higher moisture of excreta in the first half of the growth period accelerated the release of some gases, whereas gradual faeces and urine accumulation contributed to an increase in the concentration of selected organic compounds. 5. A portable FTIR analyser is a useful device for measuring gas concentrations in commercial turkey farms, and it supports determinations of tolerable emission limits in turkey production" |
