Retrospective survey on the mortality on non-human primates at Everland Zoological Gardens (1976-1999).

The mortalities of the monkeys that have been raised in Everland Zoological Gardens within a designated period (1976-1999) were retrospectively analyzed based on the clinical charts and/or autopsy reports. During that period, a total of 161 monkeys from 8 species were died. Noninfectious and traumatic factors, respiratory and digestive disorders account for the majority of cause of death. 62% of the death was concentrated in the winter season. The mortality of female and male was 53 and 47%, respectively. The mortality of adult monkey (62%) were significantly higher than that of newborn (23%) and juvenile monkeys (15%) due to neoplasia and senile changes.
