Calcium - Feed Ingredient

Calcium is an essential macromineral required for numerous physiological functions in horses, including bone formation, muscle contraction, nerve transmission, and enzyme activation. It is a primary structural component of bones and teeth, with approximately 99% of the body’s calcium stored in the skeletal system.

In equine nutrition, calcium is commonly supplied through feed ingredients such as limestone (calcium carbonate) or dicalcium phosphate. It can also be added to feed formulations via high calcium feeds like alfalfa.

The following equine feeds, supplements and products contain Calcium as an ingredient.
