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.

What does copper do for a horse?

Copper is a critical element in many important metabolic pathways in horses. Copper is necessary in bone formation, elastin formation, haematopoesis, pigment formation, reproduction and immune system function.

What happens if a horse has too much zinc?

What mineral is toxic to horses?

How do you get rid of excess copper?

Can you reverse copper toxicity?

Consuming a lot of copper-rich food and taking copper dietary supplements can raise blood copper levels. This can result in acute copper toxicity, sometimes called acquired copper toxicity, in which your blood copper levels spike suddenly. They can be returned to normal with treatment.

How do you get rid of copper overload?

Doctors can treat copper toxicity and other types of heavy metal poisoning with the following treatments: Zinc: Prevents copper from accumulating in the liver and gastrointestinal tract. Chelation therapy: Binds copper particles in the bloodstream into a compound that the kidneys filter and excrete in the urine.
