| 摘 要： | 褐家鼠(Rattus norvegicus Berkenhout)的日食量随体重的增加而增大,而日食量指数则以幼体最高。幼体(体重30—50g)每昼夜消耗小麦4.51g,黄谷11.46g、鲜玉米36.17g。亚成体(体重50—80g),耗小麦5.53g、黄谷12.98g,鲜玉米36.78g。成体(80g以上),日耗小麦7.24g、黄谷15.27g、鲜玉米49.70g。每只鼠平均年耗干粮7.14公斤。褐家鼠的日食量受光照的影响。同一年龄组的个体在全黑条件下日食量指数最高,次为自然光,全光条件下最低。

| Abstract: | The daily food consumption of R. norvegicus increases with the grorwth of individuals, but, baby individuals occupy the highest index of daily food consumption (food consumption of 100g body weight). In the test, it shows that babies (body weight about 30-50g) consume wheat 4.51g, rice 11.46g, fresh corn 36.17g; sub adults (about 50-80g of body weight) consume wheat 5.53g, rice 12.95g, fresh corn 36.78g; (more than 80g of body) consume wheat 7.24g, rice 15.27g, fresh corn 49.70g. The average amount comsuption within one year for each R. norv- egicus is about 7.14kg in general. The daily food consumption of indi- viduals for each stage of R. norvegicus is effected by the hours of bri- ghtness each day where it is highest under full dark, next is under na- tural day and night, the least is under full brightness. |
