Fig. 3. Total water turnover (rH2Ofem) as a function
of body mass for lactating (filled circles, y=19.07+1.09x,
N=24) and nonreproductive (open circles,
y=3.34+0.26x, N=24) female mice at 30°C.
rH2Ofem was measured when the reproductive
females were at day 14 of lactation. Body mass is the mean value for days
913 of lactation (reproductive females) or the mean value for eight
consecutive days before the day of doubly labelled water (DLW) injection
(non-reproductive females).
