In densely populated countries like the Netherlands, nuisance caused by odor emissions from
agricultural activities is increasing. A possible remedy for this problem is the use of low emission
housing systems. Until now, however, no solid data were available to verify the effectiveness of
such systems. With the development in the mid 1990s of an adequate olfactometric technique to
quantify odor concentrations reproducibly, the different parties involved in odor regulation
decided it a necessary step to measure the odor emissions of the different housing systems for the
various animal categories. In this paper a selection of these results is reported to illustrate the
effect of two low emission housing systems for pigs. One system involves the cooling of manure,
the other involves the frequent removal of manure by flushing. Both systems were compared to
conventional housing systems with slatted floors and storage of slurry beneath slats. Most of the
sampled farms were regular livestock operations, but some were animal compartments at
research stations. In all cases production took place under standard farm management.
