PESTAB Hen mallards, pheasants, and ring doves were maintained on diets containing 10 ppm (mallards and pheasants) or 40 ppm (doves) p,p'-DDE. Some birds were subsequently injected with parathyroid hormone (PTH). The shells on the eggs laid by the DDE treated mallards decreased 20. 41% in thickness over controls, and serum calcium of the hens was depressed. No eggs were laid after the PTH injection which raised the serum calcium levels. DDE also decreased shell thickness of eggs laid by ring doves and depressed the serum calcium values. PTH increased. DDE did not decrease the shell thickness of the eggs laid by the pheasants, while PTH increased it. Neither DDE nor PTH had clear-cut effects on the serum calcium values of the pheasants.
