Prolapse of the Uterus

This involves the complete eversion of both horns of the womb which turn completely inside out. It usually takes place within 2-4 hours of the completion of farrowing but sometimes up to 24 hours afterwards. Prolonged straining causes a small part of the tube to be propelled outwards by uterine contractions.


  • The prolapse occurs over a period of approximately one hour and commences with the appearance of the red congested lining of the womb.
  • This rapidly increases in size until the large everted mass is presented.

  • Uterine prolapses are uncommon but usually occur in old sows with large litters or where large piglets have been born.
  • The supporting structures of the uterus become weak or the uterine wall becomes flaccid.
  • Faulty farrowing mechanisms.
  • Previous damage to womb.


This is obvious by the appearance.
