Eggshell Quality IV: Oystershell versus limestone and …

2020-9-23 · Most of the data suggest that the substitution of large particles of CaCO 3 (oystershell or limestone) for fine granular CaCO 3 appear to be equally effective in improving shell quality. Results suggest that larger particles of CaCO 3 may only be effective if hens are receiving inadequate calcium or in hens exposed to factors which could reduce the utilization of calcium.
