(CEN, 1999) currently being followed by many laboratories
in Europe, Australia, and Canada (Watts, 1999). Amon et al.
(1995) reported a mean exhaust fan odor concentration of
2,800 OU m–3 at 600–pig (8 to 27 kg) nursery buildings
located in Slovenia. Airflows were measured by traversing
fan outlets with a hot wire anemometer. The experiments
were carried out in the autumn with mean inside temperatures
of 25°C. The buildings were mechanically ventilated and
equipped with manure pits underneath a fully slatted floor.
The mean odor emission rate of all buildings was 488 OU s–1
AU–1. Verdoes and Ogink (1997) measured odor emissions
from a partly slatted pig nursery, which was designed for low
ammonia emission. The mean exhaust fan odor concentration
and odor emission rate were 2,109 OU m–3 and 272 OU
s–1 AU–1, respectively. The mean ventilation rate and inside
temperature were 9.2 m3 h–1 pig–1 and 27°C, respectively.
