The primary objective of the study was to quantify several important airborne contaminants in a quasi-commercial nursery facility under selected ventilation treatments. Air contaminants measured included carbon dioxide, ammonia, hydrogen sulfide, particulates, and microorganisms. A secondary objective was to determine the influence of air quality on piglet performance. Performance was measured by average daily gain and feed to gain ratios. A final objective was to investigate any apparent effects of air quality on the health of the piglets, and, to a limited extent, the workers. Clinical disease signs in the piglets were continually monitored, and in one experiment, antibody responses of several groups of piglets were determined. Indications of human health effects were obtained through interviews and general observations.
