中国地鼠的剖宫产净化

目的 通过生物净化使中国地鼠的微生物、寄生虫质量控制级别达到清洁级标准。 方法 普通级中国地鼠剖宫产后获得的仔鼠由清洁级 ICR 小鼠代乳,记录仔鼠 0 ~ 30 日龄的体质量变化和存活情况,对离乳后的仔鼠进行微生物、寄生虫质量检测。 结果 本次实验对 24 窝普通级中国地鼠进行剖宫产手术,共获得新生仔鼠 109 只,其中 5 只死胎仔,最终代乳成活 56 只,代乳成功率为 53. 85%,离乳后的地鼠经随机检测均达到清洁级国家标准。 结论 本研究对中国地鼠进行了生物净化,进一步完善了中国地鼠的质量标准化,为中国地鼠的生产、应用提供了质量保障。

Caesarian Purification of Chinese Hamster

Objective In order to make the quality control level of microbiology and parasitology of Chinese hamsters reach the clean standard through biological purification. Method First of all, the offspring of ordinary Chinese hamsters were delivered by cesarean section, and then the milk of clean grade ICR mice was substituted. At the same time, the changes of body weight and survival of 30-day-old offspring were recorded, and the microbiological and parasitological quality of weaned mice were tested. Result In this experiment, 24 nests of ordinary Chinese hamsters were selected for cesarean section, and a total of 109 new born rats were obtained, of which 5 were dead, and 56 survived, with a success rate of 53. 85%. After weaning, all the hamsters reached the clean national standard. Conclusion This study carried out biological purification of Chinese hamsters, further improved the quality standardization of Chinese hamsters, and provided quality guarantee for the production and application of Chinese hamsters.
