Abstract: The effects of some commonly consumed oils on plasma lipids, lipid peroxidation and thromboxane A_ 2 (TxA _2 ) production in chicks were studied. A total of 150 1-day-old chicks were divided into 5 groups and selected as butter, margarine, sunflower oil, olive oil and corn oil groups. The oils were added to their chow as 5% (w/w) at the beginning and 7% at the end. After a period of 45 days, blood samples were obtained from the vena axillaris. Then, plasma levels of total cholesterol, HDL-C, HDL_ 2 -C, HDL _3 -C, LDL-C, thiobarbutiric acid reactive substrates (TBARS) as malondialdehyde (MDA) and TxA _2 were measured. The results indicated that total cholesterol, HDL-C, HDL_ 3 -C and TxA _2 levels were highest in the butter group whereas HDL_ 2 -C was highest in the olive oil group. The lowest HDL _2 -C was in the margarine group and the second lowest level was in the butter group. TBARS levels were highest in the corn oil group, lowest in the butter group and increased in the order butter
