在每天的时间段内，在大鼠提供的食物中，混合不同比例的纤维素，高岭土，或水的摄入量进行了测量。在大多数混合物中，总体积增加了，但因此获得的可利用的营养素有所减少。通过混合物，大鼠有规律地摄入粗饲料至其体重的8%。每天，水高达125%/天。摘录。表明水摄入的上限并不取决于水通过肾脏排出的最大速率。各种调味品和营养素在小浓度。并不能诱导大鼠消耗更多的AMT。粗粮。完全或部分禁食1-6天后，体重。随后，由于很少或没有过量的食物，部分恢复。食物和水摄入量的短缺没有得到弥补，但支出减少了一天或多天。因此，在维持体重，食物的摄入和水的摄入。
Intakes were measured in daily periods, in rats furnished food that was mixed with diverse proportions of cellulose, kaolin, or water. In most mixtures, the total bulk eaten was increased, but the utilizable nutrients thus gained were somewhat diminished. By the mixtures, rats were regularly induced to ingest roughages to the extent of 8% of their body wts./day, and water up to 125%/day. Expts. indicated that the upper limit of water ingestion was not fixed by the maximal rate at which water could be excreted through the kidneys. A variety of flavorings and nutrients in small concns. did not induce rats to consume greater amts. of roughages. After complete or partial privation of food for 1-6 days, body wt. was subsequently partially restored with the consumption of little or no excesses of food. Deficits of food and water intakes were not paid off, but expenditures were reduced for one or more days. Thus reproducible compromises were reached among maintenance of body wt., intake of food, and intake of water.
