Résumé

The air in floor housing systems for laying hens may be more polluted than in traditional cage systems since gases are emitted from large exposed surfaces of manure and litter. In order to study odour and ammonia concentrations and emissions at different climatic conditions a small scale poultry house (climate chamber) was equipped with a floor housing system were 356 laying hens were kept. In the experiment, odour and ammonia emissions were more strongly correlated to water vapour pressure than to relative air humidity. The results suggest that control of temperature and humidity may decrease concentrations and emissions of odour and ammonia.
