Abstract
This study was conducted to evaluate the effect of whole egg supplementation on the blood lipid profiles and cholesterol levels of C57BL/6 mice. Sixty-six mice were divided into two groups: normal-diet supplemented and high-cholesterol diet supplemented. Lyophilized whole egg powder was mixed with the two diets at 2 and 10%: normal diet only, normal diet with 2 and 10% whole egg powder, high cholesterol diet only, high cholesterol diet with 2 and 10% whole egg powder. The mixed diets were fed for 5 wk and feeding condition (body weight change, feed intake, and feed efficiency ratio (FER)), blood lipid profiles (total cholesterol (TC), triglyceride (TG), high density lipoprotein-cholesterol (HDL-C), low density lipoprotein cholesterol, hepatic and fecal lipids (TG, TC)), and fecal bile acids were determined. No significant differences were found in body weight gain or FER after whole egg supplementation in both the normal and high-cholesterol diet fed groups. In the normal-diet fed mice, HDL-C increased significantly in the 2 and 10% whole-egg powder groups. In the high-cholesterol diet fed mice, administering 10% egg powder increased the atherogenic index compared to the control. Furthermore, administration of whole egg powder increased fecal bile acids dose dependently (p<0.05). These results indicate that administering 2% hen whole egg powder did not affect blood lipid profiles and was more beneficial for health by increasing HDL-C and aiding in the excretion of cholesterol by fecal bile acids than those in the control.
