Interprétation des relevés de température et d'humidité relative effectués dans une étable pour veaux

Respiratory disorders were frequently observed in a calf house despite vaccinations and drug therapy. The building was heated with a hot air system and ventilated with extraction fans. Temperature and relative humidity were recorded over a 2-week period. Temperature was in agreement with usual recommendations but relative humidity was about 100% during the whole observation period. The high relative humidity was not due to an inadequate ventilation rate but the result of large amounts of water used daily in cleaning the building.
