Abstract: 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.
