Abstract Pregnant goats were fed grass-legume silage grown on soil amended with 112 dry metric tons per hectare of municipal sewage sludge from Syracuse, New York for 135 days. Whereas PCBs were not detectable in control or sludge-grown silage, cadmium was much higher (3.81 ppm) in the sludge-grown silage as compared to the control silage (0.14 ppm). There were no consistent differences in residues of cadmium in the goat's milk or body tissues of the kids when compared to controls. The concentration of cadmium in the livers of the adult animals was significantly higher (p 〈 0.05) in the sludge treatment than controls. No significant treatment effects were observed in mutagenic responses for the goats milk. Interestingly, the pregnant goats fed the sludge-grown silage produced far too little milk for their kids while the control animals produced sufficient milk. There were no observable changes in the tissue ultrastructure as examined by electron microscopy for both the adults and the kids from either ration treatment.
