Our data extend this understanding to laying hens and suggest that microdialysis may be a valuable tool to evaluate stress in hens. Conversely, we observed that the plasma concentration of corticosterone did not predict changes to corticosterone in hen liver, kidney, or cardiac muscle. This was most apparent in the liver.
We recorded that from 90 min to 180 min after ACTH injection the concentration of corticosterone in the liver was higher than that of the plasma. We also recorded a
