Description
| - The aim of this study was to evaluate long-term (11 months) histometric parameters of thyroid gland of gimmers and ewes burdened with high-dose administration of iodine in feed. Two groups of ewes and both gimmers of Sumava mountain sheep were studied. There were six animals in each group. The feed for the two A group was supplemented by 3 mg iodine/kg of dry matter, while the two B group were given 5 mg iodine/kg dry matter. The iodine in the form of calcium iodide was contained in feed mineral supplement. The ewes were gradually carrying, lambing, lactating and finally remained barren. For both B groups significant changes in histometric parameter of thyroid gland appeared: higher percentage of large and medium follicles with increase both in height and width and lower follicular cells. Normal or lower content of triiodothyronine and thyroxine, lower content of their free fractions and bordering or elevated concentrations of thyroid-stimulating hormone in blood serum of all four test groups signalize the tendency of lowering activity of the thyroid gland. The obtained results suggest possible impact on the function of thyroid gland in sheep exposed to long-term surplus intake of iodine.
