Naryzhneva E.V. AGE AND SEASONAL DYNAMICS OF THYROID HORMONES CONTENTS IN THE BOVINE BLOOD SERUMThe article shows the dynamics of the concentration of thyroid hormones in the cattle in different age periods in spring and autumn. We studied the dynamics of thyroid hormones concentrations in the cattle in Tashlinsky District, which is a relatively prosperous area of Orenburg Oblast in terms of endemic diseases, so these studies are interesting in comparison with other biogeochemical provinces. These indicators of the thyroid status can be considered when choosing the means and methods of diagnosis, correction of diets in the animals with regard to their needs for iodine. The work revealed the physiological mechanisms that caused changes in hormonal homeostasis. The studies show that seasonal and age-adaptive rearrangements are caused by the different mechanisms which should be taken into account in the assessment and correction of the hormonal status of the animals.
