Feeding of PKE – Cooper toxicity alert!

March 18, 2013

  • PKE is an excellent source of additional Dry Matter under the current tight feed conditions.
  • Remember that PKE has significantly more copper than pasture and cows being fed >5kg are at risk of toxicity in situations where copper is being supplied from other sources.
  • We recommend stopping any additional supplementation of copper if PKE is greater than 25% of the diet.
  • Copper poisoning occurs when liver stores are exceptionally high and are released when the animal comes under stress leading to sudden death.
