Dietary Modification of Serum Cholesterol in the Chick

Influence of Fats and Choline on Liver and Serum Cholesterol in the Chick

“…Since, in these studies, the amount of fat fed was constant, the difference in effect on serum cholesterol was mainly due to the kind of fat used. The results confirm reports in the literature that the feeding of a highly-saturated fat to chicks increases serum cholesterol and that a highly-unsaturated fat counteracts this effect (March and Biely, 1959;Hegsted et al, 1960). The results are also similar to those obtained by Ahrens et al (1957) in humans fed diets of the same composition and a constant amount of fat but different in the kind of fats fed.…”

“…The data presented, however, show a definite trend toward higher plasma cholesterol levels in the groups fed animal fats. March and Biely (1959) fed chicks various fats in diets containing 20 and 26 percent protein. With both protein levels, 8 percent of Crisco, butter, lard or chicken fat increased serum cholesterol.…”

Modifying egg yolk cholesterol in the domestic fowl—a review

“…The ability of the hen to absorb dietary cholesterol is highly dependent upon the nature of dietary oil (March and Biely, 1959;Chung et al, 1965;Hulett et al, 1964;Sim and Bragg, 1977). Highly unsaturated oils have a synergistic effect on cholesterol absorption and result in increased egg yolk cholesterol.…”

Effect of Dietary Factors on Serum and Egg Yolk Cholesterol Levels of Laying Hens

“…However, the ability of the laying hen to absorb dietary cholesterol is highly dependent upon the nature of dietary oil (March and Biely, 1959;Chung et al, 1965;Hullett et al, 1964). Highly unsaturated oil such as safflower oil has a synergistic effect on cholesterol absorption and increases in egg yolk cholesterol (Weiss et al, 1967).…”
