Abstract
In Everland Zoological Gardens, the mortality by extrinsic cause in non-human primates during 1976∼1999 were retrospectively analyzed based on the clinical charts and/or autopsy reports. The number of deaths from extrinsic factor was 61 among a total of 161 monkeys which were died during that period. Among 61 monkeys of death from extrinsic factor, the number at a detailed cause were as follows: strangulation, 17(27.87%); accident fall, 15(24.59%); suffocation, 13(21.31%); drowning, 7(11.48%); death from pressure, 2(3.28%); collision, 2(3.28%); sunstroke, 1(64%); starvation, 1(1.64%); freezing to death, 1(1.64%); contusion, 1(1.64%). The number of deaths from extrinsic factor was 39 among a total of 81 squirrel monkeys which were died during that period. Among 39 squirrel monkeys of death from extrinsic factor, the number at a detailed cause were as follows; suffocation, 11(28.21%); accident fall, 8(20.51%); strangulation, 7(17.95%); drowning, 7(17.95%); death from pressure, 2(5.13%); starvation, 1(2.56%); collision, 1(2.56%). The number of deaths from extrinsic factor was 14 among a total of 50 Japanese macaque died during that period. Among 14 Japanese macaque from extrinsic factor, the number at a detailed cause were as follows; strangulation, 7(50.55%); accident fall, 6(42.85%); suffocation, 1(7.14%). It was considered that far facilities, adequate space and suitable indoor temperature are needed for the prevention of deaths of extrinsic cause at the monkey raising in zoological gardens or research center.
