This study was performed to investigate the effect of dietary vitamin E supplement and kinds of lipid on the vitamin E concentration and lipid composition in serum of the rats fed for seven weeks. Supplemented vitamin E was 300mg/kg diet as DL-a-tocopheryl acetate, and 15% of corn oil or beef tallow was added to standard diet.
The results were as follows;
1) Body weight and feed efficiency ratio were significantly increased by supplement with vitamin E, corn oil and beef tallow.
2) Serum vitamin E concentration increased significantly by supplement of vita-min E and beef tallow on the diets, while one of corn oil fed group decreased significantly.
3) The contents of triglyceride, total cholesterol, phospholipid in serum were significantly increased in the beef tallow group, and the vitamin E only-supplemented group showed significantly lower serum cholesterol centent than any others.
4) The content of HDL-cholesterol in serum increased significantly in the vita-min E only-fed group and vitamin E plus corn oil-fed group.
5) The ratio of VLDL, LDL-cholesterol content to HDL-cholesterol one in serum was significantly low in the vitamin E only-supplemented group and corn oil group, and was significantly higher in the beef tallow group than in the corn oil group.
