Behavior, appetite, and urinary cortisol responses by adult female pigtailedmacaques to cage size, cage level, room change, and ketamine sedation

Eight female pig-tailed macaques were tested, 4 in upper-row and 4 in lower-row, barren cages. Cage size was not significantly related to abnormal behavior [ included stereotypical locomotion, hair-plucking and odd gestures such as saluting ] and cortisol excretion. Ketamine...
