Atherosclerotic Response of “Aggressive'”and “Passive'”Groups of Chickens To a Cholesterol Enriched Diet. ∗

Summary

A group of male chickens exhibiting “aggressive'”and another group exhibiting “passive'”behavior were studied during and after a period of high cholesterol and fat feeding. Although the “aggressive'”groups exhibited more pronounced evidences of androgen activity, their plasma and aortic cholesterol contents were perhaps less than those of the “passive'”group. The extent and degree of coronary atherosclerosis was the same in the two groups.
