Fig. 2From: Non-invasive assessment of adrenocortical activity as a measure of stress in giraffe (Giraffa camelopardalis)ACTH response of the two giraffes as measured by each of the six EIAs. Percent response was calculated by setting the individual median FGM value for pre-injection samples from each giraffe at 100Â % and calculating the change in FGM levels for each post-injection sample.
