摘要
2004年的5～7月，在浙江省嵊州市河麂种源繁育基地对34只獐（Hydropotes inermis）的分娩活动进行了观察。结果表明，母獐通常选择安全的地点进行分娩。獐集中分娩的时间为6月3日到6月19日，占分娩母獐总数的73．53％（n=34），并且分娩多在白天进行。产程（从胎膜露出到胎盘娩出）平均为（302．20±15．27）min（n=15）。胎儿娩出的姿势多为前躯前置（前足、头先露出），占83．78％；少数为后躯前置（后足先露出），占16．22％。幼仔首次吮乳时间在单胎和多胎间无显著差异，平均为出生后（44．97±2．73）min（n=35）。幼仔出生后首次平均站立时间在双胞胎、三胞胎和四胞胎分别为（32．25±2．49）min（n=16）、（29．42±2．52）min（n=12）和（65．00±7．39）min（n=6）。每胎幼仔数越多，初生幼仔的平均体重越轻。
Calving behaviors were observed on 34 Chinese Water Deer （Hydropotes inermis ） in Shengzhou Chinese Water Deer Breeding Base, Zhejiang Province from May to July 2004. About 73.53% of births （ n = 34） occurred in the daylight hours from 3 to 19 June. On average, parturition duration lasted 302.20 ± 15.27 min （ n = 15） from the appearance of the sac to placenta out. Most fetuses （ 83.78 % ） were delivered in the pattern of head and forelegs coming out first, 16.22% were born in hind legs position. The first nursing bout occurred averagely 44.97 ± 2.73 min（ n = 35 ）after birth, and no significant differences were found between the fawns of single, twin, triplet and quadruplet. It took 32.25 ± 2.49 min（ n = 16） for twin to stand up after birth, 29.42 ± 2.52 min（ n = 12）for triplet and 65.00 ± 7.39 min （n = 6） for quadruplet respectively. The birth weight of fawn was significantly related to the litter size （ P 〈 0.01, Kruskal-Wallis H test）.
