地下室温度对小鼠生殖效应影响的试验

An Experiment on the Effect of Basement Controlled Temperature on the Mouse's Reproduction

采有地下室环境温度控制的方法,对280只昆明种小鼠进行了生殖效应影响的试验。试验在不同季节分为14个温度区,从10℃开始,每隔2℃为一个温度区。试验结果:14个温度区的母鼠受胎率(％)分别为:20、50、60、80、90、90、100、100、90、100、80、40、10、0,断奶成活率(％)分别为:18、65.9、72.2、89.7、92.3、87.8、100、94.4、100、97.8、91.1、80.6、73.3、0。试验结果表明:28℃温度区为小鼠最佳环境条件(P<0.01)。试验结论,利用新疆气候资源,建筑地下室式的小鼠饲养室可节能、节资,亦可成功克服小白鼠繁殖障碍。

Controlling the environmental temperature of the basement to search the effect on the reproduction of Mus, musculus kunming. In different seasons, the test is made in 14 different temperature ranges, we started from 10°, centigrade, making a temperature range every 2°. Result; The conceiving rates in the 14 different temperature ranges are 20%, 50% , 60% , 80% , 90% , 90% , 100% , 100%, 80%, 40%, 10%, and 0%. The surriving rates after breaking off mother milking are. 18. 0%, 65. 9%, 72. 2%, 89. 7%, 92. 3%, 87. 8%, 100%, 94. 4%, 100%, 97. 8%, 91. 1%, 80. 6%, 73. 3%, and0%, respectively. This result indicates: 22-28°,centigrade, is the best environmental temperature for mouse reproduction (P<0. 01). Conclusion: Using the climate condition of Xinjiang, we could build basement-like rooms for raising mice,so as to economize energy and investment, and to enhance the reproductive rate.
