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。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。Reproductive behaviors were observed and recorded from 24 captive badgers（Meles meles amurensis） at a badger farm in Songbei District, Harbin City by infrared monitoring equipment from March to October in 2013. Data were pooled monthly and analyzed by Excel 2010 software. 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 next year. Their pregnancy duration extended as long as 11 to 12 months that was difference from the former reports occurred in July and August. The mating time variation might resulted in the implantation time significant delayed. The mating behaviors were occurred in any hours during a day, and the mating frequency in daytime was similar to that in the night. The mating duration varied from 10 to 110 minutes with most completed between 60 and 80 minutes. An estrus period of 8 to 9 days was detected in this observation.
