Abstract

Grit from Wisconsinan drift (Sibley area) or from Illinoian drift (Neoga area) in Illinois was fed to seven juvenile hen pheasants (Phasianus colchicus) for a period of 12 weeks in fall and winter 1968-69. Extensive erosion and fragmentation of grit particles occurred in the gizzards of the hens. Concentrations of elements in the grit samples demonstrated that the gizzard was more effective than the intestine-colon complex in the removal of ions from the grit and that the chemical composition of grit from gizzards and from feces was a poor indicator of the chemical composition of grit ingested.
