PHYSIOLOGICAL MECHANISMS OF ADAPTATION AT THE COLD METHOD OF CULTIVATION CALVES
It is established, that the influence of moderate low temperatures on using a cold method of calves cultivation stimulates haematopoiesis of young cows that is shown in rising the level of erythrocytes and hemoglobin, and also in increase in phosphorus in whey of blood for strengthening power processes and thermoregulation process. The increase of the level of cortisol in blood by the 15-th day of the research specifies the development processes of adaptation, as a result the exchange processes directed to the maintenance of organism are mobilized and this fast is proved by the lowered level of triiodyronine.
Keywords: adaptation, stress, inorganic phosphorus, Cortisol, resistency, leukocytosis, triiodthyronine, thyroxine, leukocytes, thermoregulation
