Abstract

1. 1. Water deprivation (WD) resulted in increased serum osmotic pressure (OP) and decreased body weight (WB); adrenal aldosterone content did not change. 2. 2. Adrenal corticosterone content tended to be elevated during early WD, indicating a stress response, but tended to decrease after seven days of WD, suggesting adrenal fatigue. 3. 3. During water restriction (WR), after the period of weight loss, adrenal corticosterone content and serum OP were elevated. As the birds began to gain weight, aldosterone levels did not change but adrenal corticosterone content and serum OP approached control values, suggesting that the birds were beginning to adapt to the WR. Adrenal sensitivity to ACTH was indicated by the elevated adrenal aldosterone and corticosterone content after ACTH injection.
