Thrombocytopaenic purpura

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

Alternative names: bleeding

Information

 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.
