| 中文摘要: |
| 2014年6月至2015年8月期间，对分布在内蒙古自治区包头市达尔罕茂明安联合旗中蒙边境地区（41°14′ ~ 42°40′N，109°16′ ~ 110°26′E）和内蒙古自治区巴彦淖尔市乌拉特梭梭林-蒙古野驴国家级自然保护区（41°50′ ~ 42°27′N，106°15′ ~ 108°00′E）的两个野驴群（1♂3♀和2♂3♀）的繁殖行为进行研究。采用目标取样法以及目标取样法与扫描取样法相结合的方法对蒙古野驴的发情交配、产前反应、生产过程及产后行为进行观察。共记录到4类35种繁殖行为，分别为争斗行为、性行为、分娩行为和母幼联系行为。结果表明，雄驴平均日爬跨（4.2 ± 1.7）次（n = 14），射精（3.7 ± 1.3）次（n = 13），平均邀配持续时间（从雌雄驴靠近调情始到爬跨或其中一个走开止）为（26.6 ± 22.0）s（n = 13），平均抽动持续时间为（10.6 ± 1.9）s（n = 14），平均阴茎置入持续时间为（18.3 ± 8.8）s（n = 13），平均爬跨间隔为（685.7 ± 569.6）s（n = 14），平均射精间隔为（924.0 ± 790.0）s（n = 10）。蒙古野驴的交配模式属于Dewsbury分类系统中的第11种（无锁结、有抽动、单次插入、多次射精）类型和Dixon分类系统中的第12种（无锁结、有抽动、单次插入、无单次长时间插入）类型。本研究较完整地建立了蒙古野驴繁殖行为谱，提供了繁殖行为方面的基础资料。 |

| We made an observtion on the breeding behabavior on two groups (1♂3♀ and 2♂3♀) of Asiatic Wild Ass from June 2014 to August 2015 at Inner Mongolia Chaganhada Su'mu, Da'erhan Maoming'an Lianheqi Tenggenaoer District (Baotou City) (41°14′﹣42°40′N，109°16′﹣110°26′E) and the National Nature Reserve for Asiatic Wild Ass (Bayannur City) (41°50′﹣42°27′N，106°15′﹣108°00′E) (Fig. 1, Point A and Point C). We recorded the estrus and mating behavior, prenatal reaction, parturition process and postpartum behavioral expression. Our observation revealed that each male mounted female 4.2 ± 1.7 (n = 14) times and ejaculated 3.7 ± 1.3 (n = 13) times each day averagely. The average sexual solicitation duration (begin from flirting to mounting or one goes away) was 26.6 ± 22.0 s (n = 13), the twitching duration was 10.6 ± 1.9 s (n = 14), and the penis implantation duration was 18.3 ± 8.8 s (n = 13). The mounting interval was 685.7 ± 569.6 s (n = 14), and the ejaculate interval was 924.0 ± 790.0 s (n = 10). The copulatory pattern of Assiatic Ass was with no lock, thrusting, single intromission, multiple ejaculation, and no long time intromission, which belonged to type 11 in Dewsbury's copulatory-patterned system and type 12 in Dixon's copulatory-patterned system. We established the breeding behavior spectrum for the wild and provided some basic data on the breeding behavior based on our observation. |
