The Chinese pangolin ( Linnaeus, 1758) is a critically endangered species, and documents on its captive breeding and reproductive parameters are scarce. MP8, kept in the Pangolin Research Base for Artificial Rescue and Conservation Breeding of South China Normal University (the PRB-SCNU), gave birth to a male offspring (MP86) on 19 October 2011. The baby pangolin was well developed, with a weight of 120 g and a total length of 23.2 cm. The gestation length of MP8 was estimated to be from 182 to 225d. Reproductive parameters of the Chinese pangolin are discussed based on collected data about this species. The Chinese pangolin has an obvious reproductive seasonality and its gestation length is typically six to seven months. In this observation, estrus and mating principally occurred in a one-year period from February to July. Parturition principally took place from September to February of the next year. Chinese pangolins usually give birth to one offspring at a time (n = 27). Sex ratio at birth was 0.71:1 (♀:♂, n = 12). Average weight for the reproducible females was 3.57 ± 1.38 kg (2.14-6.8 kg, n = 15). We estimated that Chinese pangolins could reach sexual maturity before they were one year old.
中华穿山甲(林奈,1758年)是一种极度濒危物种,关于其圈养繁殖及生殖参数的文献稀少。华南师范大学穿山甲人工救护与保育繁殖研究基地(PRB - SCNU)的MP8于2011年10月19日产下一只雄性幼崽(MP86)。这只穿山甲幼崽发育良好,体重120克,全长23.2厘米。MP8的妊娠期估计为182至225天。基于收集到的该物种数据,对中华穿山甲的生殖参数进行了讨论。中华穿山甲具有明显的繁殖季节性,其妊娠期通常为六至七个月。在此次观察中,发情和交配主要发生在2月至7月这一年的时间段内。分娩主要发生在次年9月至2月。中华穿山甲通常一次产一仔(n = 27)。出生时的性别比为0.71:1(♀:♂,n = 12)。可繁殖雌性的平均体重为3.57 ± 1.38千克(2.14 - 6.8千克,n = 15)。我们估计中华穿山甲在一岁前就能达到性成熟。
