Feedstuff selection may impact manure dust when excreted or during
storage. Studies with pigs and cattle suggest that by adding fat
or oil to diets the feces become stickier, reducing the dust concentration
in the house. Adding ground, full-fat soybean to pig diets reduces
aerial dust levels. In confinement buildings, dust may be decreased
by 30-40 percent when full-fat soybeans are included in pig diets
instead of soybean meal. Lower dust levels improve the health of
the pigs and people who work in confinement buildings. However,
in order to avoid negative animal performance impacts, dietary
energy content should not exceed nutrient recommendations.
