[Dust reduction in pig houses].
Airborne dust in pig houses causes health problems for humans with full-time employment in pig houses. Many attempts have been made to reduce the dust burdens, but often without sufficient results. At Research Centre Bygholm ten different possibilities for dust reduction have been tested in the test section, and the results are evaluated on the basis of results obtained simultaneously in an identical control section. Until now, the two most efficient methods are addition of fat to the pigs' diet and spraying a thin layer of rape seed oil in the animal house. By adding 4% of fat to the diet, a reduction of 50% can be seen, and by spraying 5 g of rape seed oil daily per pig place, the aerial dust concentration can be reduced to about 75%. The costs are about 1 DM/pig at a price of rape seed oil of 2 DM/l.
