黑线姬鼠的耐饥试验

Evaluation on Starvation Resistance of Apodemus agrarius

以黑线姬鼠(Apodemus agrarius)为实验动物,分别在实验室温度为(10±2)℃(近春、秋季节温度)和(20±2)℃(近夏季温度)的环境中,研究断水断粮、给水断粮、断水给粮3种条件下黑线姬鼠的耐饥时间。结果表明,黑线姬鼠在(10±2)℃环境中的平均耐饥时间为(71.6±45.4)h,其中,断水断粮组黑线姬鼠的平均耐饥时间为(37.6±15.1)h,给水断粮组黑线姬鼠的平均耐饥时间为(53.5±18.3)h,断水给粮组黑线姬鼠的平均耐饥时间为(123.8±37.4)h;黑线姬鼠在(20±2)℃环境中的平均耐饥时间为(140.4±69.7)h,其中,断水断粮组黑线姬鼠的平均耐饥时间为(92.9±20.9)h,给水断粮组黑线姬鼠的平均耐饥时间为(105.1±23.9)h,断水给粮组黑线姬鼠的平均耐饥时间为(223.1±55.0)h。结果显示,黑线姬鼠对食物的依赖性大于对水的依赖性,且黑线姬鼠在温度较高的环境中耐饥性更强。

In the present study, the tolerable time for starvation of Apodemus agrarius under experimental condition with ambient temperature of （10±2）℃ （similar to the temperature of spring and autumn） and （20±2） ℃ （similar to the temperature of summer） was evaluated respectively. For both experimental ambient temperatures, water and food shortage treatment, water supply and food shortage treatment, and water shortage and food supply treatment were set. The results showed that the average tolerable time for starvation ofApodemus agrarius under ambient temperature of （10±2） ℃ was （71.6±45.4） h, and that of water and food shortage treatment, water supply and food shortage treatment, and water shortage and food supply treatment was （37.6±15.1 ） h, （53.5± 18.3 ） h and （123.8±37.4） h, respectively; the average tolerable time for starvation of Apodemus agrarius under ambient temperature of （20±2） ℃ was （140.4±69.7） h, and that of water and food shortage treatment, water supply and food shortage treatment, and water shortage and food supply treatment was （92.9±20.9） h, （105.1±23.9）h, and （223.1±55.0） h, respectively. The combined data suggest that the reliance of Apodemus agrarius on food is more than water, and Apodemus agrarius has stronger starvation resistance in environment with higher ambient temperature.
