Abstract
Summary Chicks were fed mustard oil, sesame oil, coconut oil and hydrogenated groundnut oil mixed with the basal diet with or without the addition of cholesterol. The level of oil was 10% and that of cholesterol 1% of the basal diet. The different diets were fed for 8 weeks and plasma contents of different lipids were estimated. Addition of oils alone in the diet increased the plasma NEFA values without producing any change in other fractions of plasma lipids. When the different oils were fed in addition to cholesterol, there was a rise in total plasma cholesterol, β-lipoprotein cholesterol, β-lipoprotein percentage, triglycerides and NEFA values of plasma. The rise in plasma cholesterol was maximum in chicks fed cholesterol along with hydrogenated oil or sesame oil and minimum in chicks fed cholesterol along with mustard oil, with intermediate rise after coconut oil. The solubility of cholesterol was highest in coconut oil and least in mustard oil. Hypercholesteremia does not seem to depend on saturation or unsaturation of the oils or on the solubility of cholesterol in the oils.
