Abstract
The studies were carried out on calves from 1st to 21st day of life. Cortisol level and reactivity of adrenal cortex to exogenous ACTH were analysed. The highest level of cortisol in blood was observed in first days of life in the calves. Then the level became considerably decreased. In the experimental group two subgroups differing in cortisol level were distinguished. High or low level occurred on the first day and the difference kept over two weeks of their life. Adrenal cortex just on the day of birth showed full functional maturity of molecular receptors binding ACTH.
