Modelled daily O input and output fluxes through the body water of a suckler cow. Values below and above the lines denote the mean and range (in parentheses) of the flux rates (mole d−1) and δ18O (‰) for the years 2000 to 2004, respectively. The fluxes are ordered according to δ18O. Line width is proportional to flux rate. The mean and range of δ18O in body water is identical to fecal, urinary and sweat water.
