Figure 5.

Total protein by refractometer results from the water deprivation test. Elephants are listed on the x-axis in the same order as Figure 3 and total protein (refractometer) values are on the y-axis. Corresponding results are displayed for each elephant as bars showing the difference between the T₀ and T₁ total protein values. Unfilled bars indicate elephants with an increase in total protein and filled bars indicate elephants with a decrease in total protein over the water deprivation period. The shaded area represents the interquartile interval obtained from phase 1 results.
