Minerals are divided into two groups based upon the dietary level needed. Micro- minerals (trace minerals) are required in small amounts and are expressed as mg/kg

  • Cobalt
  • Selenium
  • Iodine
  • Choline
  • Iron

Cobalt

Function

Fibre digestion and structural component of vitamin B12 that is synthesized by bacteria found in the cecum and colon.

Selenium

Function

Selenium works jointly with vitamin E as an antioxidant to protect body tissue from damage. Selenium works inside the cell as part of an enzyme (glutathione peroxidase) to prevent the formation of the free radicals, while Vitamin E protects cell membranes by blocking free radicals at the membrane level.

Iodine

Function

Synthesis of thyroid hormones that control energy metabolism, growth and muscle sensitivity (speed at which they contract).

Choline

Function

It is also known as vitamin B4 although it is required in a much higher level than vitamins. It helps to maintain cell membrane integrity and normal maturation of bone cartilages.

Iron

Function

The horse has a low requirement for dietary iron, as it recycles iron from haemoglobin and makes it available for the synthesis of “new” haemoglobin.  Forage will supply all the iron a horse needs and there is no need for iron supplementation.
