How to Tell If a Pig Is in Labor
A sow will exhibit specific signs prior to the impending births of its piglets. It can take up to 24 hours from the time a sow begins to show signs of labor until it actually delivers its piglets. Knowing the signs of labor can help you attend to the sow and observe for any potential problems that could arise. If you notice the sow becoming too nervous prior to giving birth, it may help to remove it from any other pigs, as the sow can develop aggression towards the other pigs.

Tips & Warnings
Prepare a quiet area for the sow before birthing to keep it comfortable and stress-free.
Notify the veterinarian immediately if the sow passes bloody fluid without straining, if it strains without giving birth, if foul-smelling discharge is expelled or if the sow develops extreme weakness. Without assistance, the sow and its litter can die.
