圈养马来穿山甲的怀孕期

马来穿山甲(Manis javanica)为极度濒危物种,已报导该物种的怀孕期长度差异较大,需要更多的直接观察案例来确定其怀孕期长短。广西林业科学研究院穿山甲人工救护与繁育基地通过室内圈养方式驯养穿山甲,记录了14例马来穿山甲产仔情况:其中圈养前野外受孕、场内产仔9例;野外受孕、圈养死亡的母体1例;不确定受孕情况母兽产仔1例;圈养条件下交配怀孕并产仔3例,其中2例是母兽进场后第2次产仔。根据初步观察结果,估计马来穿山甲孕期为5~6个月。

The Gestation Length of Sunda Pangolin (Manis javanica) in Captivity

Sunda Pangolin (Manis javanica), a critically endangered species, has considerable variation in the reported periods of pregnancy, and more evidences are needed to verify their gestation duration. Fourteen cases of domesticated breeding were recorded in GFRI Pangolin Rescue and Breeding Base: nine births were given by female pangolins which might be fertilized before arriving at the base (Fig. 1 and 2), one cub was produced by a dam that might be pregnant pre-domesticated and died in the base (Table 3); one case unidentified in or out pregnancy; and three complete pregnancies recorded from mating to parturition within the base (Table 1), while two of them were second productions of the dams after arriving at the base. According to our preliminary results we suggested that M. javanica gestation period range from 5 to 6 months.
