Dolomite powder is a stock feed supplement. Dolomite is a natural product containing Calcium and Magnesium.
Calcium is required for the nervous and muscular systems, normal heart function and blood coagulation. It is also needed for bone growth. However Calcium must always be considered in conjunction with magnesium. Excessively nervous behaviour can be attributed to a lack of magnesium. Many animals have become much easier to manage when dolomite has been added to their rations, changing from excitable to quite calm individuals.
