Iron toxicity (Vitamin E Deficiency)

Iron toxicity occurs when the sow and her piglets are deficient in vitamin E. Iron dextran injections become toxic and cause severe muscle reactions at the injection site.

  • Anaemic.
  • Death occurs within 24 hours.
Sows
  • None
Weaners & Growers
  • Rare

Causes / Contributing factors

  • Vitamin E deficiency in the sow occurs when fats in the diet become rancid or cereals or corn have fermented and spoiled and the vitamin E is destroyed. Piglets are then born deficient
  • Poor quality iron dextran will predispose.
