摘　　要：目的观察两种饲料饲喂BALB／c小鼠的效果。方法将10对BALB／c小鼠随机分为两组：A组5对小鼠，饲喂^60Co辐照灭菌的颗粒饲料；B组5对小鼠，饲喂121℃、7min抽真空高压消毒的颗粒饲料。比较两组小鼠的生长、发育和繁殖情况。结果虽然^60Co辐照灭菌的颗粒饲料的价格高于121℃、7min抽真空高压消毒的颗粒饲料，但采用^60Co辐照灭菌饲料饲喂，不论是母鼠的生殖能力和仔鼠的生长速度，还是提供1只离乳小鼠的耗料成本，均优于采用121℃、7min抽真空高压消毒饲料饲喂。结论^60Co辐照灭菌饲料用于饲养BALB／c小鼠较为经济合算。Objective To observe the effectiveness of two feeds in feeding BALB/c mice. Methods Ten couples of BALB/c mice were divided randomly into two groups with 5 couples of animals in each. Group A mice were fed with the feed sterilized by ^60Co-γ ray irradiation, and group B mice were fed with the feed steri- lized by pre-vacuum autoclaving at 121℃ for 7 minutes. The growth, development and reproduction of mice in the two groups were compared. Results Although the feed price of group A was higher than that of group B, the reproduction of female mice and the growth rate of their offspring in group A were better than those in group B, and the feed consumption cost for producing a weanling mouse in group A was lower than that in group B. Conclusion It is cost-effective to use the feed sterilized by ^60Co-γ ray irradiation for feeding BALB/c mice.
