This study was designed to determine hair cortisol levels in the New Zealand White (NZW) rabbit and to examine possible differences in the cortisol levels of hair samples collected from different body regions in stable environmental conditions. The experiment was performed on eight 18 month-old female NZW rabbits. All animals were shaved to collect hair samples from 26 different body regions. Hair cortisol levels were determined by the RIA method. The mean hair cortisol concentration for the 26 samples in the 8 animals was 2.12±0.05 pg/mg (mean±standard error). This study reveals individual hair cortisol distributions in the 8 animals (P<0.001) and no statistical differences (P>0.05) in hair cortisol levels among the different body sites in each of the animals.
