Noninvasive monitoring of adrenocortical function in captive jaguars (Panthera onca).
Jaguars are threatened with extinction throughout their range. A sustainable captive population can serve as a hedge against extinction, but only if they are healthy and reproduce. Understanding how jaguars respond to stressors may help improve the captive environment and enhance their wellbeing. Thus, our objectives were to: (1) conduct an adrenocorticotrophic hormone (ACTH) challenge to valid...
متن کاملRetrospective Study of Morbidity and Mortality of Captive Jaguars (Panthera onca) in North America: 1982–2002
One hundred seventy-two medical records of captive jaguars (Panthera onca) were examined from 30 American Zoo and Aquarium Association (AZA) institutions housing jaguars between 1982–2002. The study determined common causes of morbidity and mortality, and the influence of age, gender, and melengestrol-acetate (MGA) exposure on these rates. The most common causes of morbidity in captive jaguars ...
متن کاملSeasonal variation in the endocrine-testicular function of captive jaguars (Panthera onca).
Captive adult male jaguars (Panthera onca) from two locations in southeast Brazil were studied to evaluate the effects of season on endocrine and testicular function. For assessment of testicular steroidogenic activity, androgen metabolite concentrations were measured in fecal samples collected one to three times per week over 14 ( n=14 ), 9 ( n=1 ) or 7 months ( n=1 ). To assess seasonality, d...
متن کاملChanges in the fecal concentrations of cortisol and androgen metabolites in captive male jaguars (Panthera onca) in response to stress.
In the present study we determined the efficacy of the measurement of fecal cortisol and androgen metabolite concentrations to monitor adrenal and testicular activity in the jaguar (Panthera onca). Three captive male jaguars were chemically restrained and electroejaculated once or twice within a period of two months. Fecal samples were collected daily for 5 days before and 5 days after the proc...
متن کاملCutaneous adenocarcinoma of sebaceous gland in a captive male jaguar Panthera onca: a case report.
High incidence of neoplasia in captive jaguar (Panthera onca) has been recorded but there have been no reports of cutaneous adenocarcinoma of the sebaceous gland. A high incidence of neoplasia has been detected in captive jaguars, possibly associated with longevity and husbandry practices in captivity. Neoplasm is a major cause of mortality in jaguar. Tumours of sebaceous gland are common in ol...
