Why Low Iron Matters
Why Low Iron Matters
- Iron is already commonly high in grass, hay and haylage.
- Commercial feeds and supplements often add more iron unnecessarily.
- Hidden iron can come from mineral ingredients such as lower-grade magnesium oxide.
- High iron can interfere with the balance of copper and zinc.
- Copper and zinc are often the minerals most in need of targeted support.
Do Horses Need Additional Iron
In most cases, horses do not need extra iron added to their diet. Iron is present in virtually everything a horse eats or drinks, including grass, hay, haylage, water, soil, commercial feeds, beet pulp, alfalfa and many vitamin and mineral supplements.
The issue is not only the iron declared on a feed label. Hidden iron can also be present as a contaminant in feed-grade minerals used to manufacture supplements
Iron, Copper and Zinc Balance
One of the key concerns with excess iron is the way it can affect the balance of other trace minerals, especially copper and zinc. These minerals are important for hoof quality, skin, coat pigment, immune support and connective tissue health.
When forage contains high iron and low copper or zinc, simply adding a general multi-vitamin and mineral supplement may not solve the problem. A forage-focused approach looks at the mineral pattern in the forage and supplements the nutrients most likely to be limiting.
Iron
Often already high in forage, soil and water. Usually not a mineral that needs adding to horse balancers.
Copper
Important for coat pigment, connective tissue, hoof quality and iron metabolism
Zinc
Important for skin, hoof horn, immunity, wound healing and enzyme function
Signs That Trace Mineral Balance May Need Reviewing
Many common horse health concerns can have more than one cause. However, when the diet contains high iron and low copper or zinc, trace mineral balance is worth reviewing
