Eryvac
Expand All
  • Eryvac® is registered for the control of Erysipelas polyarthritis in lambs and sheep. Erysipelas infection may result in damage to the joints of sheep leading to arthritis.

    Arthritis affects all the sheep producing regions; it is not restricted by geography.

  • For the control of erysipelas infection in sheep causing:

    • Lameness and inability to stand & walk
    • Issues with transport, not ‘fit to load’
    • Reduced weight gain
    • Losses through trim and condemnations at the abattoir
    • Chronic arthritis caused by erysipelas leads to production losses due to poor body and reduced wool growth.
    • Control of Erysipelothrixrhusiopathiae arthritis in all classes of sheep.

     

    • Eryvac is the only vaccine that controls erysipelas arthritis
    • If you save 1 in 200 lambs from arthritis, a complete Eryvac program has paid for itself1
      • A complete Eryvac program has 3 shots, 1 dose in ewes at pre-lambing and 2 lamb doses, one at marking and one at weaning
    • Eryvac can improve profits by up to $0.82/DSE in prime lamb flocks and $0.59/DSE in fine wool flocks2
