Limestone | Feedipedia

Calcitic limestone contains 36-38% calcium and can safely be fed free choice (ad lib) mixed with salt. Dolomitic limestone contains at least 5 % magnesium carbonate and should not be used for poultry, but it is as good as calcitic limestone for other animals. Portland and natural cement can be used instead of limestone.

The chemical composition of pure limestone approaches the theoretical composition of calcite (56 percent CaCO and 44 percent CaCO 2). Limestones in which the content of MgO is between 4 and 17 percent are called dolomitic limestones. As the magnesium content increases, limestones pass through a series of intermediate varieties into the dolomites.
