The experimental studies revealed and analyzed the dynamics, protein and saline metabolism, resistance to stress factors and adaptive capacities (total proteins and protein fractions, urea, macro elements Ca, P, Na, K, content of glucose, bactericide activity, cortisol concentration) of calves in their early postnatal ontogenesis under the combined influence of stresogen thermal maintenance factor, noise and parasitic factors. There were established that the fluctuations of the researched physiological parameters have the phasic character. The tested indices, in major cases were quantitatively lower in the group of animals affected by the combined stressor factors. Two ascends in changing of the indices have been observed: at the 7-8-th and at the 25-30-th days at birth that coincided with critical development periods: immunodeficiency, depression of the stresogen reaction, depression of dominance and retardation. The positive effect has been registered also upon stress resistance and adaptation capacities of the organism.
