Abstract

To study the effects of chicken fat, lard, and soyboan oil on lipid metabolism in ras, 48 male Wistar rats were randomly divided into six groups: chicken fat, soybean oil, lard, each at 15% or 8%. After four weeks, the rats were sacrified, and the serum and liver were collected for analysis of triglyceride (TG), phospholipid (PL), total cholesterol (TC), LDL-cholesterol and HDL-cholesterol content. Different dietary fat sources did not affect concentrations of PL, TC, LDL-cholesterol and HDL-cholesterol in serum, regardless of the amount of fat in the diet (p > 0.05). There were significant differences in various lipid concentrations in liver. Serum TG concentration was the lowest in rats fed soybean oil diets. Liver TG concentration was the highest in the lard fed groups (p <0.05). Liver PL concentrations in chicken-fat-consuming rats were the second highest when compared with those of the rats fed soybean oil and lard. Liver TC among the six groups of rats differ from each other. The concentrations decreased in the order of 15% soybean oil, 8% soybean oil , 15% chicken fat, 8% chicken fat, 8% lard, then 15% lard (p <0.05).
