Indications

  • Primary nutritional iodine deficiency due to low dietary intake is almost impossible in horses:
    • Secondary deficiency due to feeding plants such asBrassicaspp containing thiocy anates.
  • Skin disinfection.
  • Goitre and weakness in young foals due to dietary excess in pregnant mares.

Under no circumstances should pregnant mares be fed supplements containing iodine. This is especially important if foals are born with enlarged thyroids - this indicates a dietary excess, not a deficiency.

  • Thyroid enlargement in adult horses is rarely, if ever, due to low dietary iodine.
