| 中文摘要: |
| 2013年3 ~ 10月，使用红外监控设备对哈尔滨市松北区某狗獾养殖场的24只笼养东北亚种狗獾 （Meles meles amurensis）的繁殖行为进行全天候观察记录。狗獾3月末至5月初交配，翌年3月末至4月初产仔，妊娠期长达11 ~ 12个月。而以往国内文献报道狗獾交配时间主要分布于7 ~ 8月，这种交配时间的变化表明其延迟着床的时间可能也存在较大变化。对交配期内全天各时段交配频次的观察发现，交配可在全天任一时间段发生，昼、夜差异不大。交配时长10 ~ 110 min，多数交配的时长为60 ~ 80 min。观察还发现，狗獾交配期内交配频次和时长具有明显的周期性变化。 |
| 英文摘要: |
| Reproductive regulation of 24 captive badgers（Meles meles amurensis）were observed and recorded around the clock on a badger farm in Songbei District, Harbin City by using infrared monitoring equipment from March to October in 2013. Moreover, all data were analyzed by Excel 2010 software. The results indicated that badgers mated from the end of March to the beginning of May (Fig. 1), and gave birth from the end of March to the beginning of April, thus their pregnancy duration extended as long as 11 to 12 months. While the former internal treatises reported that badgers’ mating behavior mainly occurred in July and August. The variation of their mating time showed that the time of delayed implantation also had a significant change. The study of mating frequency in each time period of the whole day indicated that the mating happened at any time, and the frequency of daytime was similar to nighttime. The lengths of mating ranged from 10 to 110 minutes, mainly between 60 and 80 minutes. The observation also found that badgers' mating (including the frequency and length of daily mating) had obvious periodicity. |
