Calcium carbonate is used as feed nutrition enhancer to strengthen the nutritional value of basic feed.

Description

Calcium carbonate is an inorganic compound with the chemical formula of CaCO ₃, commonly known as limestone, limestone, stone powder, etc. Calcium carbonate is alkaline, basically insoluble in water and soluble in hydrochloric acid. It is one of the common substances on the earth. It exists in aragonite, calcite, chalk, limestone, marble, travertine and other rocks. It is also the main component of some animal bones or shells.
