title: [Morphometric structure of thyroid and adrenal glands in bulls under different modes of adaptive technology].
abstract: This work was carried out to study dynamics of morphometric structure of thyroid and adrenal glands in bulls brought up in early postnatal ontogenesis at lowered (-4.4-(-)8.0 degree centigrade) and raised (8.7-20.5 degree centigrade) environment temperature with further grow and fattening using intensive technology with application of new biogenic matters. For the first time it has been experimentally proved the expediency of correction of morphometric structure of investigated endocrine glands in bulls under condition of joint application of Suvar with Polistim or with DAFS-25 during the various periods of postnatal ontogenesis. Special features of morphometric structures of the thyroid glands (diameter, the area of follicles, thickness of thyroid epithelium, follicles index) and the adrenal glands (weight, width of zones of cortical and brain substances, the areas of cells and nuclei, and nuclear cytoplasmic ratio) in animals maintained under condition of adaptive technology have been investigated. It has been established that the endocrine glands morphometric parameters in bulls brought up at both lowered and raised temperature are more relief under combined effect of Suvar and DAFS-25 than Suvar and Polistim.
