Contrary to the findings in mammals, prolonged treatment with protamine zinc insulin did not increase the rate of weight gain in the juvenile duck. Higher levels of this hormone retarded growth, lowered food intake and produced a substantial hypoglycaemia. No change in fat content or distribution was produced by the insulin treatment. Production of antibodies to exogenous insulin was rare and unlikely to neutralize the action of this hormone.
