What mineral is toxic to horses?

Incorrect levels of some minerals may develop into toxic states of the horse. The most well-known is Selenium.

Can a horse get too much zinc and copper?

A safe upper level for zinc is 500mg per kg of total diet. Amounts greater than 700mg per kg of diet can affect copper absorption, particularly in young horses which can result in Developmental Orthopedic Disease (DOD). Other examples of Zinc toxicity are lameness and stiffness.

How do you know if your horse needs copper?

One of the most obvious signs of potential copper deficiency is a change in coat colour due to loss of pigmentation. The coat might appear dull, frizzy or discolored with a reddish tinge. Copper deficiency can also cause anemia and weakened blood vessels, bones, or joints in adult horses.

What makes a black horse turn brown?
