Summary
Sixty Leghorn hens were randomly divided into 5 groups of 12 and individually fed a control diet, or diets containing 10 and 20 ppm dieldrin, or diets containing 100 and 200 ppm p,p′-DDT for a 12-week period. Average egg production per bird, egg weight, dry shell weight, shell thickness (not including membranes), and shell calcium were not affected by feeding the insecticides. In addition, the length of the clutch or the number of clutches during the 12-week period were not affected. However, egg weight increased with time during the experiment, and eggshell thickness decreased with successive eggs within a clutch.
