Increasing age influences uterine integrity, but not ovarian function or oocyte quality, in the cheetah (Acinonyx jubatus).
Although the cheetah (Acinonyx jubatus) routinely lives for more than 12 yr in ex situ collections, females older than 8 yr reproduce infrequently. We tested the hypothesis that reproduction is compromised in older female cheetahs due to a combination of disrupted gonadal, oocyte, and uterine function/integrity. Specifically, we assessed 1) ovarian response to gonadotropins; 2) oocyte meiotic, ...
متن کاملInduction of ovarian activity in the cheetah (Acinonyx jubatus).
Serial injections (i.m.) of 10 mg follicle stimulating hormone (FSFI-P) to cheetahs for 5 days followed by human chorionic gonadotropin (hCG, 500 IU) administered on both Days 6 and 7 resulted in ovarian follicle development and/or ovulation in six of seven attempts. One additional female given the same gonadotropin regimen when distinct corpora lutea (CL) were visible on the ovaries failed to ...
متن کاملThe cheetah (Acinonyx jubatus) dewclaw: specialization overlooked
Both the behavioural and the morphological analyses confirm the special role of the dewclaw in the cheetah: a strong hook to stop running animals by using the energy of the victim itself. However, this would hardly be an explanation for the rather large dewclaw in the puma. The present finding of the puma as an intermediate between the cheetah and other large felids for dewclaw size, supports t...
متن کاملThe composition of cheetah (Acinonyx jubatus) milk.
Milk was obtained from two captive bred cheetahs. The nutrient content was 99.6 g protein; 64.8 g fat; and 40.21 g lactose per kg milk. Small amounts of oligosaccharides, glucose, galactose and fucose were noted. The protein fraction respectively consisted of 34.2 g caseins per kg milk and of 65.3 g whey proteins per kg milk. Very little variation in milk composition among the individual cheeta...
متن کاملACTH stimulation test in the captive cheetah (Acinonyx jubatus).
Serum cortisol response was assessed in 8 captive cheetahs, of varying ages, after the intravenous administration of 500 microg of tetracosactide (Synacthen Depot, Novartis, Kempton Park) while maintained under general anaesthesia. In addition, 8 cheetahs were anaesthetised and given an equal volume of saline in order to establish baseline cortisol concentrations at similar stages of anaesthesi...
