The histological structure and morphometric and some histochemical indices of thyroid gland of maral as a subspecies of red deer at the postnatal stage of ontogenesis were studied. It was established that the gland was structurally formed by the time of the birth. C-cells are detected at 6 months of age. With age, the ratio of follicles of different sizes changed: smaller forms predominate in newborns and those 6 months old, medium and large predominate in adults and in old deer. Histological, morphometric, and histochemical data indicate to activation of the thyroid gland in the period of intensive growth for up to 6 months and a gradual decrease in activity over the next years of life. During aging, along with an increase in stromal elements, large follicles with colloid are stretched and resorption processes in the follicles are reduced.
