摘　　要：目的对野生来源树鼩的繁殖性能及仔树鼩的哺育方法进行了研究,探索出一套经济实用、规模化的繁殖方法,取代以往依靠人工喂养的方式。方法提供适合的饲养管理环境和条件,完全由母树鼩主动自然哺育新生树鼩,观察统计怀孕率、产仔数、成活率、仔树鼩生长情况。结果 2010年通过120对繁殖群,成功离乳354只F1代仔树鼩,自然繁殖成活率为90.76%。目前已建立野生来源树鼩繁殖群150对,F1代繁殖群40对,为建立达到标准要求的树鼩种群奠定了基础。结论该方法的树鼩繁殖率和成活率较高,成本低且操作简单,为树鼩实验动物化应提倡的一种方法。Objective Observation the reproductive features of wide original tree shrews. Exploring an optimum method that is economical, practical and on a large scale to raising tree shrews baby. Instead of artificial feeding which were reported previously. Method Provided suitable environment and conditions for feeding and management, entirely breast feeding and care by mother tree shrews. More data were collected and statistics from the pregnancy rate,each litter size,survival rate and observation the growth of young tree shrews. Results In 2010,354 tree shrews offspring have been successfully weaned from 120 couples and the survival rate of natural reproduction was 90.76 percent. Now breeding population had been established with 150 couples of wild original tree shrews and 40 couples of F1 generation,which have laid the foundation for reaching standard requirements. Conclusion This method was one of higher reproductive and survival rate, low cost and simple to operate, it should be promoted to scale produce the tree shrews as laboratory animals.
