摘　　要：目的了解Wistar大鼠不同发育时期的摄食量。方法慢性毒性与致癌合并试验中的对照组,采用4周龄SPF级Wistar大鼠,雌、雄性大鼠各60只,试验前观察1周,常规饲料喂饲;试验期为104周,在试验的前13周内,每周测量一次摄食量,以后每4周测量一次摄食量。结果报告了Wistar大鼠不同发育时期的摄食量。雄性大鼠在104周内的平均摄食量为26.3 g/d/只,雌性大鼠在104周内的平均摄食量为19.5 g/d/只。结论本文报告的Wistar大鼠不同发育时期的摄食量可为相关技术人员提供一些参考。Objective To learn about the food consumption of rats dieted for 2 years. Methods The control group of a combined chronic toxicity and carcinogenicity test include 60 male and 60 female Specific Pathogen-Free Wistar rats （4 weeks old）. The rats were acclimated for 1 week prior to initiation of the test. The rats were dieted with conventional feed. The study duration was 104 weeks. Food consumption were measured weekly for the first 13 weeks and once every 4 weeks thereafter. Results Food consumption of Wistar rats in their different life period was reported. The mean food consumption for male rats during 104 weeks was 26.3g/day/ rat and that for female rats was 19.5 g/day/ rat.Conclusion The data about the food consumption of Wistar rats reported in this paper can provide some reference for relevant technical staffs.
