目的
2
探究北方地区黑白加州王蛇人工冬眠的适宜环境条件,明确其冬眠行为、生长及繁殖规律,建立适宜北方地区的人工控温冬眠技术。
方法
2
以北京动物园9条成体黑白加州王蛇为对象,设冬眠组6条、常温对照组3条,采用逐渐降温的方式开展人工冬眠试验,监测温湿度、体重、行为及繁殖指标。
结果
2
黑白加州王蛇冬眠周期为2021年10月中下旬至次年3月中下旬;初眠期平均温度13.25±3.10 ℃,深眠期平均温度10.51±2.59 ℃,苏醒期平均温度15.10±4.87 ℃。冬眠组个体冬眠后体重平均下降8.6%(
P
<0.05),次年 4 月恢复摄食后体重增幅达8.0%(
P
<0.05),对照组各时间节点体重无显著变化;环境温度高于20 ℃时,蛇类逐步恢复摄食。冬眠组在初眠期、深眠期、苏醒期的不活动行为占比分别为79.6%、96.4%、74.4%,其中深眠期占比显著高于其余时期及对照组(44.8%)(
P
<0.05)。6月合笼繁殖,冬眠组可完成繁殖,对照组无交配及产卵现象。
结论
2
保持环境温度8.0~13.0 ℃,湿度65%~90%,可实现加州王蛇冬眠与繁殖成功。
Objectives
2
The environment conditions suitable for the artificial hibernation of Lampropeltis californiae in northern regions of China were studied and the behavior of hibernation
patterns of growth and reproduction in Lampropeltis californiae were identified to establish the artificial hibernation techniques with controlled temperature suitable for northern regions of China.
Methods
2
6 Lampropeltis californiae reared in Beijing Zoo were artificially cooled for hibernation and 3 were hibernated in the normal temperature (control group). The experiments of artificial hibernation were conducted by gradually cooling down to monitor the temperature and humidity
body weight
behavior
and indexes of reproduction.
Results
2
The cycle of hibernation in Lampropeltis californiae was from mid to late October 2021 to mid to late March of the following year. The average temperature during the primary hibernation
deep hibernation
and recovery was 13.25±3.10 ℃
10.51± 2.59 ℃
and 15.10 ± 4.87 ℃. The average loss of weight in Lampropeltis californiae in the hibernation group after hibernation was 8.6% (
P
<
0.05)
and the average increase of weight reached 8.0% (
P
<
0.05) after resuming feeding in April of the following year. There was no significant change in weight at each time point in the control group. Lampropeltis californiae gradually resumed eating when the environmental temperature exceeded 20℃. The proportion of inactive behaviors in the hibernation group during the primary hibernation
deep hibernation
and recovery was 79.6%
96.4%
and 74.4%
respectively. The proportion of inactive behavior during the deep hibernation was significantly higher than that in the other periods and the control group (44.8%) (
P
<
0.05). Lampropeltis californiae in the hibernation group bred in the cage in June completed reproduction
while that in the control group had no behavior of mating or egg-laying.
Conclusions
2
Maintaining the temperature and humidity at 8.0-13.0 ℃ and 65%-90% in environment can achieve the successful hibernation and reproduction of Lampropeltis californiae.
