Airborne dust in swine houses can cause serious health problems for humans as well as for animals. The aim of this experiment was to evaluate the airborne dust concentration range and effectiveness of cooling fan with spraying misting systems in the gestation houses in the management practices of China. The experiment was implemented in a gestation barn housed 239 gestation pigs in Hebei Province of China. The tests showed that the average airborne dust concentration was about 4.70 ±3.24 mg/m3 in cold weather and 2.18 ±1.61 mg/m3 in warm weather, respectively. The high dust concentration of 17.55 ± 1.18 mg/ m3 in winter and 15.25 ± 1.77 mg/m3 in summer happened in the feeding period. When the misting cooling system with droplet diameter of 20-50µ m turned on, the average airborne dust concentration could be reduced by 75%, from 7.94 ±4.67 mg/m3 to 1.98 ±1.80 mg/m3, during the feeding period.
