Plasma hormones in neotropical and domestic cats undergoing routine manipulations
2007 Research in Veterinary Science (82): 263-270
Many neotropical felids are threatened with extinction and information on their physiology is required to assist in conservation. Their reproduction in captivity is poor, particularly for the smaller species. Several factors may be responsible, but stress is probably the most important. We assayed cortisol, LH, FSH, prolactin, testosterone, estradiol, and progesterone in single blood samples obtained under sedation from seven neotropical species and, for comparison, in stressed and unstressed domestic cats. Cortisol was also assayed in serial blood samples obtained after ACTH administration in _Leopardus tigrinus_, _L. wiedii_ and domestic cats. While, in general, the results were fairly consistent, there were some statistically significant differences between species that were large enough to be of practical importance.
