摘要
This study documented the reproductive performance of 210 adult female Formosan sambar deer (FSD, Cervus unicolor swinhoei) from four semi-domesticated deer herds in Taiwan. An extensive analysis of 525 reproductive records from 2000 to 2008, including the conditions of estrus, gestation, and parturition was conducted. The mean ± S.E.M. lengths of the estrous cycle, gestation, and fawning interval were 18.2 ± 0.5 d (n = 56), 258.6 ± 0.3 d (n = 160), and 369.9 ± 2.3 d (n = 122), respectively. Hand breeding was performed between June and December (n = 494), with the majority (93.1%) occurring between July and October (P < 0.05). Fawning occurred from February to September (n = 318), and most frequently (83.0%) between April and June (P < 0.05). Pregnancy rate per mating in FSD hinds was 64.4%. There was a 1.3:1 male-to-female ratio at birth (P < 0.05) among 320 fawns, and only two cases of twinning (0.63%). The postnatal mortality rate was 6.6% (21/320), and the mortality rate in fawns before weaning did not exceed 8% on any farm. Fecundity was enhanced by high pregnancy rates and high offspring survival rates. This study provides baseline information on reproductive performance of FSD, which should be valuable to veterinarians and deer industry personnel for management of FSD on farms in subtropical countries.

从四个半驯养梅花鹿存栏这项研究证明210成年雌性台湾水鹿(FSD,水鹿鳖)的繁殖性能在台湾。进行525繁殖记录2000至2008年进行了广泛分析,包括发情,妊娠,分娩和的条件。平均值±S.E.M。动情周期的长度,妊娠和摇尾乞怜间隔分别为18.2±0.5 D(N \x3d 56),258.6±0.3 D(N \x3d 160),和369.9±2.3 D(N \x3d 122)。六月和十二月间进行手工养殖(N \x3d 494),与七月和十月(P之间的大部分(93.1%)发生在FSD海因兹每交配受孕率为64.4%。有一个1.3:1的男性对女性的出生性别比(P在出生后的死亡率为6.6%(三百二十零分之二十一)和死亡率小鹿断奶前不超过8%,在任何农场。繁殖力高怀孕率和高的后代存活率提高。这项研究提供了关于FSD的繁殖性能基线资料,这应该是有价值的兽医和鹿业人才,为消防处对中亚热带国家的农场管理。
