The aerosol found in turkey rearing confinements was evaluated with a method for dust suppression. An experimental barn was equipped with a water spray dust suppression system; the control barn was not so equipped. Dust samples from the barns were collected weekly for 17 weeks. Blood samples and live birds were examined biweekly. The aerosol contained mold spores, bacteria, dander, feather fragments, wood shavings, and crystalline silica (7631869). Concentrations were consistently and substantially lower in the sprayed barn than in the control barn. Biological evaluation showed no significant difference in the incidence of airsacculitis between birds from both barns. Birds from both barns were positive for Mycoplasma- meleogridis at the beginning of the experiment and for Newcastle disease by week 10. The mortality rate of the control barn was 1.74 times that of the sprayed barn. The authors conclude that the reduced mortality rate in the sprayed barn was a result of its diminished aerosol concentration.
