Blood CORT is commonly used to assess stress in rodents, but sampling can trigger a rapid stress response. This study aims to identify whether faecal CORT metabolites (FCM) can reflect changes in CORT induced by 7-day food restriction (FR) and an ACTH challenge. Blood and 24hr faecal samples were collected at baseline and Day 7 for control (n=8) and FR (n=10) rats. On Day 8, after a baseline blood sample, an ACTH injection was administered and followed by blood and fecal sampling. Results showed increased serum CORT and FCM in response to FR. Increased adrenal sensitivity with FR was illustrated by a greater increase in serum CORT compared to control in response to ACTH. Lastly, although it appeared that ACTH induced an increase in FCM in FR and control, only the latter reached statistical significance. Thus FCM might be better suited for quantifying chronic rather than acute changes in CORT.
