摘要
目的建立棕背的实验室繁育方法,测定棕背生长和繁殖数据,为开展棕背实验动物化研究提供基础。方法将黑龙江省牡丹江市牡丹峰林地的野生棕背引入实验室,于大型硬壁式啮齿动物负压隔离器内进行人工饲育、繁殖,测定棕背生长和繁育数据,评价棕背实验室繁育效果。结果棕背在实验室条件下可以实现人工饲育、繁殖。妊娠率54.55%,平均妊娠期为20.4 d(18~22 d);一个繁殖期内平均繁殖2.9次,最高繁殖次数为7次,远远超过自然条件下所统计到的繁殖次数(1~4次);平均窝产仔数(4.3±1.22)只,单窝最高产仔数为8只;幼仔离乳率94.8%,生长发育状况良好。结论实现了棕背的实验室繁育,测定了棕背在实验室条件下的生长和繁育数据,为棕背实验动物化打下了基础。
Objective To establish a breeding method of Myodes rufocanus in the laboratory,collect their growth and reproduction data,and provide a basis for carrying out the experimental animalization. Methods Wild Myodes rufocanus caught in the Moranbong woodland were brought back to the laboratory. They were bred artificially in a large hard wall rodent negative pressure isolator. Their growth and reproduction data were recorded for evaluating the results of breeding.Results The Myodes rufocanus were successfully bred in the laboratory. The pregnancy rate was 54. 55%. The average pregnancy length was 20. 4 days（ 8 to 22 days）. During one breeding period,they gave birth 2. 9 times on average. The maximum number of births was 7 times,far more than the number tested under field conditions. The average litter size was4. 3 ± 1. 22. The highest litter number of a single nest was 8. The weaning rate of pups was 94. 8%. The growth and development of pups were good. Conclusions The breeding method for Myodes rufocanus is established. The growth and reproduction data are tested too. The results of our study laid a foundation for the experimental animalization of Myodes rufocanus.
