Abstract

1. The effects of twice daily injections of corticotrophin (1 IU/kg body weight) or restriction of food intake to 75% of normal on body mass, adrenal mass and adrenal cholesterol were determined on chicks from 1 to 21 d of age.

2. Only the birds subjected to restricted feeding showed a reduced growth rate.

3. There was no adrenal hypertrophy in birds receiving corticotrophin but in the restricted group there was transient hypertrophy at 2 weeks.

4. Depletion of adrenal cholesterol was noted only in the birds receiving corticotrophin.

5. It is concluded that neither depletion of cholesterol nor hypertrophy is an inevitable consequence of enhanced adrenal cortical activity.
