Abstract

This study was performed to investigate an influence of ventilation rate change on the level of aerial contaminants in the confinement pig building. There was not significant difference in total dust and total airborne microorganisms among three levels of ventilation rate (p>0.05) whereas the increased ventilation rate lowered the levels of respirable dust and gaseous compounds (p<0 05). Based on the results, it was concluded that the suspended gases in the confinement pig building generally followed the air streamline formed by the ventilation whereas the ventilation rate had little effect on the gradient of particulates, especially total dust, due to gravity generated by their size and weight. The findings that the concentrations of total airborne microorganisms were not also significantly different among the ventilation rates could be explained in terms of the fact that airborne microorganisms are easily adsorbed on the surface of dust particle.
