Abstract
Summary
In the present investigation in the beagle, there was a decrease in both the TBW and ECW compartments expressed as a percentage of body weight with growth, but the ICW compartment did not change significantly. The decrease in the TBW and ECW compartments occurred at three different rates: the first significant change in rate occurred between the ages of 1 and 2 months and the second between 4 and 5 months. The volumes of TBW and ECW calculated as a percentage of body weight were 85 and 56%, respectively, in the newborn and 60 and 29%, respectively, in the 1-year-old, while ICW was 30.6% throughout growth.
