Abstract
Summary and conclusion
Male chickens were fed for 6 months on rations containing (a) no supplement, (b) cholesterol plus corn oil, (c) cholesterol plus corn oil-sterol and (d) cholesterol plus fatty acids rich in linoleic acid. Atherosclerotic severity tended to be greatest in the group given fatty acids and least on the sterol-containing diet. Since sterol excretion indicated a similar rate of cholesterol absorption on the cholesterol-supplemented diets, it appears that the principle in corn oil which retards avian aortic atherogenesis is present in the sterol fraction.
We gratefully acknowledge the help of Dr. V. K. Babayan, E. F. Drew and Co., Boonton, N. J. for supplying us with the fatty acid fraction and that of Dr. S. S. Chang, Staley Mfg. Co., Decatur, Ill. for providing corn oil sterols used in this study.
