摘　　要：目的探讨磨牙石在大、小鼠饲养中对饲料消耗量与动物活动力的影响。方法C57／BL6小鼠30只和SD大鼠30只按随机数字表法分为对照组（没放置磨牙石）和放置磨牙石组，每组5笼。给予定量饲料，称取和记录消耗饲料量并进行数据对比，实验时间，进行开场实验，记录分析动物自主探究及活动能力。结果对照组饲料消耗量明显高于放置磨牙石组，磨牙石成为了大、小鼠日常休闲娱乐的玩具，且到实验结束为止对照组与磨牙石组动物在活动力与探究行为上无明显差异（P〈0．05）。结论饲养笼内放置磨牙石既能节约饲料成本还能丰富动物的日常生活，符合动物福利。Objective To explore the effect of tooth grinding stone in mice and rats breeding. Method Thirty C57BL/6 mice and 30 SD rats were randomly divided into 2 groups respectively at the age of 3 weeks. Group 1 was as control, and group 2 was given tooth grinding stone in cages, with 3 animals in one cage. All animals had free access to water and everyday weighed feed, the feed consump- tion were monitored. All animals were tested by open field test 3 months later. Results The feed consumption of group 1 was higher than group 2. Animals in group 2 like playing with the tooth grinding stone. Open field test show that there was no difference between group 1 and group 2 in the activity factor and emotionality factor. Conclusion Tooth grinding stone could save feed and make the life of animals colorful.
