Suppression of avian hepatic cholesterogenesis by dietary ginseng.
The effect of the ginseng root powder on avian hepatic cholesterol biosynthesis and serum lipoprotein cholesterol levels were examined. Lohman strain broiler females were fed for 4 weeks a corn-based diet (control) or an experimental diet in which 0.25% Korean ginseng was incorporated (treatment). B.-hydroxy-B-methylglutaryl-CoA) HMG-CoA reductase activity was significantly lower (P < 0.01) in the treatment group (47% of control activity). Ginseng treatment affected a lowering of the serum total cholesterol level (83% of control, (P < 0.05) and of serum low density lipoprotein cholesterol level (77% of control, P < 0.05). The mechanism of the hypocholesterolemic action of ginseng involves the suppression of cholesterol biosynthesis.
