Abstract

This study compared the dust, bioaresol and gas characteristics dynamics inside a pig barn with or without cyclone deduster (CD). The detection of inert minerals and heavy metal contamination was also done for both feed and dust. During a 24”hour monitoring at 30”minute interval, the peak level of dust concentration in the control was recorded at 20:00 with 6,763 ㎍/㎥ for Total Suspended Particulate (TSP), 2,966 ㎍/㎥ for Particulate Matter 10 (PM diameter 23 ㎛) was detected in the test room and was lower than the TSP (>37.29 ㎛) found in the control room at 5.1 %. Moreover, the CD was effective in reducing the bacterial count, NH3 and CO2 levels for 3 weeks. An analysis on the heavy metal contamination of the dust showed that Pb had the highest concentration at 5,695 ppm followed by Cr, AS Cd and Hg at 3,455, 1.3, 0.33 and 0.015 ppm, respectively. The above findings proved that the CD can mitigate the harmful effects of dust and bioaresols to animals and livestock farmers.
