摘　　要：在实验室笼养条件下将28只健康成年树鼩按1:2或1:3的雄雌比例配对饲养,并每隔3周进行一次检查,通过一年的试验饲养,研究结果表明,这批实验树鼩共受孕45次,分娩37窝,流产2窝,死产3窝,总产仔147只,成活139只,另有3只母树鼩怀孕待产。每只母树鼩产仔2～3窝,每窝2～5仔,幼仔初生体重为(10.4±1.2)g,40日龄断奶体重为(66.2±15.7)g。该方法树鼩繁殖率和成活率极高,成本相对较低且操作简单,是一种值得参考和借鉴的新方法。Under the situation of the laboratory cages, the adult 28 healthy tree shrews were kept couples feeding by comparisons of 1：2 or 1：3 male and female, and we carried on a check every 3 weeks. The result showed that tree shrews conceived 45 times in total, giving birth to babies 37 nests, having misbirth 2 nests, having stillbirth 3 nests. The number of producing young tree shrews amounted to 147, here werel39 survivors, another 3female tree shrews were pregnant. Each female tree shrew bred 2-3 nets, and each time was 2-5 young tree shrews .The mean weight of newborn was（0.4 ±1. 2）g and the wean weight was （6.2±15.7）g. on the 40th day. The method of our laboratory breeding tree shrews is not only high breeding and survival rates, but also low the cost and simple operation. Therefore, the new breeding method is worthy of reference with draw lessons.
