Serum lipids and lipoproteins in clinically healthy male Camels (Camelus dromedarius).

Blood samples were collected from the jugular vein of 87 Iranian male dromedary camels of different age groups (<3, 3-5, 5-6 and 6-8 years). Variations in the serum concentrations of cholesterol, triglyceride, total lipid, very low-density lipoprotein (VLDL-cholesterol), low-density lipoprotein (LDL-cholesterol) and high-density lipoprotein (HDL-cholesterol) were investigated. The concentrations of cholesterol, triglyceride, total lipid, HDL-cholesterol, LDL-cholesterol and VLDL-cholesterol in the different age groups were significantly different (p < 0.05). With an increase in the age of the animals, there were highly significant increases in the cholesterol, triglyceride, HDL-cholesterol and VLDL-cholesterol concentrations, whereas the concentration of LDL-cholesterol decreased (p < 0.001).
