“…This result was inconsistent with previous findings as female cheetahs with high FGM values can be reproductively inactive and irregular in cycling (Jurke, Czekala, Lindburg, & Millard, 1997;Wielebnowski et al, 2002). However, Jurke et al (1997) analysis of metabolite measurement in cheetahs, one female demonstrated periods of increased ovarian activity while exhibiting high FGM levels at the same time.…”

-The purpose of this study was to assess the personality of 17 South African cheetahs at the San Diego Zoo Safari Park. A multifaceted approach of observer ratings (rating method), behavioral data (coding method) and hormone monitoring was used to examine individual differences. Knowledge of these individual differences, i.e., personality, is essential to better husbandry and management in a zoological facility. Principal Components Analysis yielded five personality components: Insecure, Aggressive, Interactive, Active, and Unsociable. Comparing the personality components with gender, reproductive success, and hand-rearing history of the individuals revealed significant associations. The components Aggressive and Interactive had a positive correlation with behavioral diversity, and the component Unsociable had a positive correlation with self-maintenance. There was a significant gender difference, with males scoring higher on Aggressive and Interactive. Individuals who scored higher on these components also had higher levels of behavioral diversity, and males displayed higher levels of behavioral diversity than females. In addition, individuals that were reproductively successful scored higher on the component Unsociable, as well as displayed higher FGM levels. This study demonstrates the value of using a multifaceted approach to further understand and assess animal personality. Information gained from this study can ultimately help zoological facilities manage and assist with reproductive efforts in populations that are not currently self-sustaining, such as the cheetah.

Ultrasonographic and laparoscopic evaluation of the reproductive tract in older captive female cheetahs (Acinonyx jubatus)

The study uniquely described the clinical value of trans-abdominal ultrasonography for monitoring features characterising the oestrous cycle in female cheetahs (Acinonyx jubatus). The reproductive tracts of 21 female, nulliparous and relatively aged (median: 11 and interquartile range: 9.25 -14 years) captive cheetahs resident on two sites in Namibia were assessed by trans-abdominal ultrasound. Subsequently, the ovarian findings on ultrasound were compared with direct visualisation whilst performing laparoscopic sterilization. A combination of these observations supported by concurrent sampling for vaginal cytology and serum progesterone concentrations (SPC) defined the oestrous status of individual animals. At one site, six cheetahs had been implanted with the GnRH agonist, deslorelin as a contraceptive at least once within the preceding 11 years. On ultrasound, 31 uterine horns and 35 ovaries with discernible structures on 28 (86%) were visualised in the 21 cheetahs. The uterine body was difficult to visualise due to its intrapelvic location. Eleven of 19 uteri (58%) visualised showed endometrial oedema suggestive of oestrogenisation. The uteri of four cheetahs (19%) showed evidence of mild cystic endometrial hyperplasia (CEH). Paraovarian (PO) cysts were seen on ultrasound (n = 21) and laparoscopy (n = 26) in 16 (76.2%) and 18 (85.7%) cheetahs respectively. Ovarian volumes obtained from ultrasonographically determined dimensions predicted cyclic activity. Laparoscopy showed that 19 ovaries had discernible follicular structures. In the study population, 10 (47.6%) were in pro-oestrus or oestrus; none in the luteal phase and 11 (52.4%) in anoestrus. Trans-abdominal ultrasound in combination with SPC and vaginal cytology was used with acceptable accuracy to assess cyclic ovarian activity in captive cheetahs. A considerable 1 proportion of this aged population showed ovarian activity and the prevalence of PO cysts was notable. A history of prior deslorelin treatment was not associated with either reproductive activity or uterine pathology

Fecal cortisol metabolites as indicators of stress in crab-eating-fox (Cerdocyoun thous) in captivity

Blood samples collection is a common method in biological research using domestic animals. However, most blood sampling techniques are complicated and highly invasive and may therefore not be appropriate for wildlife animals in research concerning stress. Thus, a non-invasive method to measure steroid hormones is critically needed. The first goal of this study was to determine how glucocorticoids concentrations are impacted by translocation and reproductive activity in crab-eating-fox (Cerdocyoun thous) in captivity. The physiological relevance of fecal glucocorticoid metabolites was further validated by demonstrating: (1) The translocation of a male to a females enclosure resulted in a 3.5-fold increase compared to baseline concentrations, (2) changes in adrenocortical activity, as reflected in concentrations of fecal cortisol metabolites during reproduction, gestation and lactation in females foxes, indicating that social interactions resulted in large increases of fecal glucocorticoids metabolites during the reproductive season. From these findings we conclude that fecal samples can be used for the non-invasive assessment of adrenocortical status in crab-eating-fox.
