Abstract

It was investigated functional status and compensatory adaptation morphogenesis of microstructures of pituitary, adrenal, thyroid, thymus, bursa Fabricius, spleen of industrial growth quails breed «pharaoh» under stress at different periods of ontogenesis. It was established that the development of anxiety stage at 40 daily quails accompanied by activation of the hypothalamic-pituitary adrenocorticotropic system in the form of increased secretory activity of basophils in pituitary with simultaneous stress-induced increase of corticosteroids in interrenal tissue, decreased secretory activity hromaphins in adrenal glands and increase synthetic and secretory activity in thyroid. The course of immuno-physiological reactions in the immune-competing tissues of the thymus and bursa under the influence of stress was characterized by a decrease in the index by 12.8 - 58.9%, the area of cortical substance - by 31.2%, in the spleen - the appearance of primary lymphoid nodes in the amount of 2,50±0,11 compared to the original state. At 75 days of age, the development of the stage of resistance coincided with the period of sexual activity and manifested by a decrease in the functional reserves of the organs of the endocrine and immune system, the intensity of the processes of immunogenesis.

Keywords: pituitary; adrenal gland; thyroid; thymus; bursa Fabricius; spleen; adaptation; quails; stress.
