Abstract

|
The present study was performed to investigate the effect of ozonation of the swine nursery building on indoor air quality and growth efficiency of the weanling piglets. Forty 21-day-old, cross-bred weanling piglets were housed in two ozonated or unozonated pens(10 males and 10 females per pen) for 3 wk alternately in a swine nursery building and this procedure was repeated three times, Ozone was generated using a commercials apparatus outside the nursery building and infused into the nursery building through a duct at a level of 0.03?. Indoor concentrations of harmful gases were measured at 2-h intervals for a 24-h period per each 3-wk feeing trial. Indoor ammonia and carbon dioxide gas concentrations were reduced by the ozonation(p＜0.01) by 21％ and 7％ respectively, compared with those of the control(unozonation), although hydrogen sulfide concentration was not affected by the treatment.
