What does calcium do in horses?

Calcium is an essential mineral for horses and plays a variety of important functions in the body. Here are some of the effects and functions of calcium in horses:

1. Bone and Dental Health: Calcium is a major component of bones and teeth. It contributes to the development, maintenance and strength of the skeletal system. Adequate calcium intake is important to prevent fractures, osteoporosis and other bone tissue problems.
2. Muscle Contraction: Calcium is critical for normal muscle contraction, including skeletal muscle, cardiac muscle, and smooth muscle in the internal organs. It is involved in the transmission of nerve signals that control muscle contraction.
3. Blood clotting: Calcium plays an important role in blood clotting. It is necessary for activating clotting factors in the blood to stop bleeding and aid in wound healing.
4. Nervous System and Signaling: Calcium is essential for the proper functioning of the nervous system. It is involved in the transmission of nerve impulses and plays a role in regulating neurotransmitter release.
5. Enzyme activation: Calcium is involved in activating certain enzymes that control important metabolic processes in the body.

A lack of calcium can lead to disturbances in these functions and have a negative impact on the health and performance of the horse. Horses should be fed a balanced diet providing adequate calcium and supplementation with calcium may be necessary in consultation with a veterinarian or nutritionist to meet the horse's needs.
