Can horses overdose on magnesium?

Too much magnesium in the blood (hypermagnesemia) is rare, but horses receiving excessive doses of magnesium sulfate for constipation may show signs of sweating, muscle weakness, and rapid heartbeat and breathing rate. Cardiac arrest can occur with very high blood magnesium levels.

Is zinc harmful to horses?

What does cobalt do to horses?

Cobalt is required by the bacterial flora of the hindgut of the horse to manufacture Vitamin B12. Vitamin B12 is then absorbed by the body and combines with iron and copper for the production of red blood cells. It is also needed in energy and nitrogen metabolism.

What is the number one killer in horses?
