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.

      Watch for signs of nesting in the sow. It may paw with its front feet in an attempt to build a nest, according to the University of California Davis School of Veterinary Medicine. The sow can also become restless and may pace around its pen.

      Observe the sow's respiration rate. A sow's respiration rate will increase from 25 to 30 breaths to nearly 80 breaths a minute, indicates C. Robert Dove, Extension Animal Scientist of the University of Georgia Cooperative Extension.

      Inspect the sow's teats for milk production. The sow's udder will also become firmer and enlarged.

      Expect the sow to become quiet and find a place to lie down just prior to birthing. You may notice that the sow will pass bloody fluids and fecal matter before giving birth to its piglets. When the sow draws up its legs and begins to shiver, the birthing process will begin.
