Cadmium in Tissues of Swine Fed Barley Grown on Municipal Sludge‐amended Soil

Barley was grown on soil which had been amended five years earlier with a municipal sewage sludge from Syracuse, New York. The harvested grain was fed to growing male swine for 73 days and, following slaughter, animal tissues were analyzed for cadmium. The concentration of cadmium in kidney and liver were greater (p < 0.01) in the sludge treatment group than in the controls. Average daily feed intake and weight gain was greater (p < 0.01) for the animals in the sludge treatment group but the feed/gain was not different (p > 0.05) between the two treatment groups.
