Apparent solubility rates for oyster shell (OS) and limestone (LS) were determined in two experiments. Twelve hours after force-feeding 10 grams of either hen size oyster shell or hen size limestone to 30 fasting hens, retention of hen size LS in the gizzard was significantly (P<0.01) greater than for hen size OS. In vitro solubility determinations revealed no differences between LS and OS. However, the solubility rate was slightly faster for pullet size than for hen size particles of both LS and OS.
