Soil ingestion was measured under farm conditions by use of the titanium content of feces and soil as an indicator. Ingestion of soil ranged from 1.2 to 5.7% of dry matter in the diet when swine were on lots with bare soil and from 3.3 to 8.0% when swine were on grass pasture. Background levels of soil ingestion ranged from 0.3 to 0.8% when swine were confined to concrete. Soil ingestion can be an important source of animal exposure when chemical contaminants occur in soil.
