Line graph represents average weekly intake of DDT per pheasant for three levels of contaminated feed. Bar graph illustrates total intake of DDT per bird. Breeder Mortality Losses of breeders fed contaminated diets began 22 days after these feeds were first offered. For birds fed contaminated diets through egg- laying, mortalities among the 500 ppm DDT group were six males (100 percent) and one female (6 percent) ; and among the 100 ppm group, two males (33 percent) and one female (6 percent). There were no losses in the group fed the 10 ppm diets. For pheasants fed with DDT until the start of egg-laying, losses in the 500 ppm group were six males (100 percent) and five females (29 percent). In the 100 ppm group, one female (6 percent) succumbed. There were no deaths in the 10 ppm group. All males from the 500 ppm groups died within.
