broiler chicken, emission, ventilation rate, greenhouse gas
Abstract
An experiment was carried out to determine emissions of greenhouse gases from broiler chicken house during one
fattening period (i.e. 40 days). The greatest concentrations of water vapour (H2O), carbon dioxide (CO2), nitrous oxide (N2O) and methane (CH4) were observed in the first ten days. Increasing emissions of all greenhouse gases were as a consequence of increasing ventilation rate, although their concentrations were decreasing. It was released 83.8 . 106 m3 polluted air containing 211 314 kg CO2, 5 kg N2O, 1 323 kg CH4 and 178 914 kg H2O over a period of whole fattening time.
