Relationship between the blood thyroid hormones and lipid profile in Moghani sheep; influence of age and sex


The aim of this study was to determine the correlation between thyroid hormones and lipid profile in blood of Iranian Moghani sheep in different ages and sexes. Blood samples were taken from the jugular vein of 260 clinically healthy and nonpregnant animals in eight age groups (1–14 days, 1–2, 2–3, 3–6, 6–12, 12–24, 24–48, and  > 48 months) in autumn. The plasma was analyzed to determine thyroxine (T4), triiodothyronine (T3), free thyroxine (fT4), free triiodothyronine (fT3), cholesterol, triglyceride, high-density lipoprotein (HDL-cholesterol), low-density lipoprotein (LDL-cholesterol) and very low-density lipoprotein (VLDL-cholesterol) concentrations. According to our data from Moghani sheep, an increase in age results in significant decreases in the plasma concentrations of T4, T3, fT4, fT3, cholesterol, and HDL-cholesterol (P < 0.05) but no gender-dependent significant differences in the studied parameters were found.
