Previously, we reported that a diet including sesame meal (SM) increased plasma total and high-density lipoprotein (HDL)-cholesterol concentrations in goats. In the present study, the components in the sesame meal that can increase plasma total and HDL-cholesterol concentrations have been examined. In experiment 1, we gave goats defatted sesame meal diet (DSM) to investigate the influence of ether extract fraction remained in sesame meal. Corn gluten meal diet (CGM) was also fed to goats as a high-protein diet to examine the influence of high dietary protein level caused by usage of sesame meal. Plasma total and HDL-cholesterol concentrations of goats fed DSM and CGM did not change during experimental periods though they were elevated by feeding SM. In experiment 2, the influence of sesame oil and corn oil added in diets on plasma total and HDL-cholesterol concentrations in goats was investigated. Plasma total and HDL-cholesterol concentrations were increased by feeding both corn oil diet and sesame oil diet. In conclusion, the increase in plasma HDL-cholesterol concentration by feeding sesame meal was resulted by the effect of ether extract fraction including sesame oil or some lipid-soluble components remained in sesame meal.
