Abstract: The reproductive behavior of seven captive mandrills (Mandrillus sphinx) were observed in Chengdu Zoo by using Alloccurrence SamplingMethods fromJanuary to September in 2001. The results indicated that During estrus, the perineumof the female swelled and turned to be red. Estrus synchrony between the females and the males in a group was found in captive. Reproduction was not apparently seasonal. The menstrual cycle was 30.55 ±0.77 days (N = 11) and the menstrual duration was 2.38 ±0.13 days. The mandrills were found to have apparent copulatory patterns that included teeth-chattering, mounting, inserting, and thrusting. The mating behavior occurs generally in daytime and it lasted 14.90 ±0.34 seconds (N = 246). Mating gesture was face-to-back type. The gestation was about 163 - 175 days, with an average of 171.13 ±4.19 (N = 8) days. The birth occured at night and lasted 2 - 3 hours. The mandrill observed gave birth to only one offspring each. The lactating time decreased as the young grew up, but lactation played an important role before weaning took place.

摘要: 2001 年1~9 月, 在成都动物园用所有事件取样法对人工饲养状态下7 只(5 ♀♀, 2 ♂♂) 山魈的繁殖行为进行了观察。结果表明, 山魈的繁殖没有明显的季节性, 一年四季均发情繁殖, 月经周期为30.55 ±0.77 d (N = 11) , 行经期2.38 ±0.13 d (N = 16) ; 交配行为均发生在白天, 交配持续时间为14.90 ±0.34 s (N = 246) , 具有明显的交配模式, 其中碟牙、爬跨、插入和抽动4 种行为在每次交配中都出现, 交配姿势仅有背腹式一种; 孕期为171.13 ±4.19 d (N = 8) , 产前不废食; 分娩都在夜间进行, 产程2~3 h ; 育幼期哺乳时间随幼仔长大逐渐减少。
