以小白鼠为实验动物，对甘肃地区筛选出的7株猪发酵床土著菌种进行了安全性评价。结果显示，接种后的小白鼠均无死亡，采食情况、行为能力、体貌特征均无异常，表明筛选出的7个土著菌种均安全可靠，可以用于猪发酵床制作接种并作为合成菌剂的备选菌种。

The safety evaluation of virulence test about 7 strains native microorganism which isolated from pig fermentation bed was studied .The test animals are mice， Through breeding and observing the experimental animals， we could assess the 7 strains native microorganism were safety at first.The results showed that the mice were alive， and eating situation， active ability and posture，facial features were normal.
