Research to improve cage-free air quality and hen welfare
Electrostatic precipitator technology investigated for use in layer houses to reduce dust levels and improve hen welfare in cage-free systems.
Compared with cage housing, cage-free houses have reduced air quality with higher dust and ammonia levels. Fine dust particles can travel into the lungs of animals, causing or exacerbating lung and heart diseases.
Dust particles can also transport odors and harmful gases as well as microorganisms, including pathogens. There is…
