Effect of a Formalin Stress on the Adrenal Function of the Domestic Pigeon (Columba livia)

Abstract

The present study reveals that in domestic pigeons the glandular epinephrine (E) storage is higher in the morning than in the evening. Formalin administration in pigeons depleted the adrenomedullary content of E with elevation of blood sugar in the morning only. The glandular norepinephrine (NE) remained unaffected after formalin stress both in the morning and in the evening.
