of Orally Administered Zinc-65 by Wild Small Mammals
B. Golley, Richard G. Wiegert and Robert W. Walter
Zinc-65 uptake and excretion
by wild and laboratory small mammals differed in both the assimilation and
excretion phases of the retention curves. The
wild forms assimilated less of the ingested zinc and excreted the assimilated
zinc at a faster rate than did the laboratory mouse and rat.
The differences in rate of assimilation may be due to the mode of
administration; those in excretion may be a function of the differential
activity or metabolism of the species under caged conditions.
