Thrombocytopaenic purpura

Thrombocytopenia purpura is a rare disease seen in piglets of 7-21 days characterized by a failure in coagulation.

Alternative names: bleeding


 It is a rare condition seen only in young piglets from 7 to 21 days of age. It starts because  the sow's colostrum contains antibodies that destroy platelets (thrombocytes) of the piglets.

The disease begins 7-10 days after consumption of colostrum. The piglet dies due to a failure of the normal mechanisms of coagulation. The disease is very sporadic but when it is present may affect up to half of the litter.



Sows, nursery and fattening

  •  Not present

Lactating  piglets

  • Sudden death.
  • Dead piglet’s skin shows bite marks or injuries resulting in hemorrhages and / or bruising.
  • The hemorrhages are evident in all body tissues.
  • Anemia.


Causes / Contributing Factors

  • The immune system of the pregnant sow recognizes the pig platelets as foreign proteins and produces antibodies against them.
  • The boar used also influences the formation of these antibodies.



  • Perform necropsy.



  • There is no treatment. Affected piglets need special care.
  • Take the litter to another sow.
  • Genetic change (boar).
