摘　　要：本文讨论了40对树鼩笼养条件下的繁殖。雌雄1:1配对饲养,受孕率为58.1%,每窝产仔2—6只,平均3.48±0.8只,初生幼仔体重均值为10.30±1.2克,35日龄断奶体重均值为59.1±17.6克。正常怀孕期41—45天。在半人工哺乳情况下,新生儿的成活率为74.3%。在与某些灵长类资料比较后,我们认为,树鼩的繁殖特性与灵长类有别。The paper d-iscussed reproduction of the tree shrews in captivity. The ratio of male to female is 1:l.The pregnancy ratio is 58.1%. The litter size is 2 to 6 with mean = 3.48 ±0.8. The mean weight of newborn is 10.30±1.2g. Wean weight is 59.1±17.6gin 35 days.Normal pregnancy period is 41 to 45 days. Comparing with some primate animals suggest that the characteristic of reproduction in tree shrews are different from primates.
