Sample 1 PN: US 5012761 • Original Abstract: Chickens are fed a composition including fish oil over a period of time. Modified eggs laid by such chickens contain substantial quantities of omega 3 polyunsaturated fatty acids. The modified eggs are fed to humans with the result that serum cholesterol, serum triglycerides and blood pressure are reduced a compared to human eating a like number of regular eggs with a subsequent decrease in heart disease. Enhanced Abstract: A method of increasing the OMEGA-3 polyunsaturated fatty acid content of chicken eggs comprises the steps of: (a) obtaining a grain based chicken feed; (b) forming a mixture of the chicken feed an oil containing OMEGA-3 polyunsaturated fatty acid such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) with the oil being from about 3. 0 percent to about 10. 0 percent by weight of the mixture; (c) thereafter feeding chicken laying hens the mixture as a primary source of food for the hens; and (d) collecting the eggs of such hens laid subsequent to the hens eating the mixture. The oil is fish oil, and fish oil may be deodorized. Said hen eggs contain low cholesterol content, which can be fed to humans with the result that serum cholesterol, serum triglycerides, very low density lipoprotein and blood pressure are reduced as compared to humans eating a like number of regular eggs with a subsequent decrease in heart disease for example coronary heart disease.
