NOTE: Rates have been converted to units of OU/s-m2 for comparison purposes, where OU = odor unit.

aNet odor emission rate (inlet concentration was subtracted from outlet concentration).

bNumber of animals calculated from average animal space allowance.

cPigs were fed acid salts.

dMultiphase feeding.

eOdor units normalized to European odor units based on n-butanol.
