Near the farrowing date, the sow will act restless and begin to nest. When the sow stands up, the piglets congregate around her legs and can easily get trapped when she lies down again. Domesticated and wild pigs have an obvious difference: the formers tails are curled, but the latters tails are straight.

Pigs tend to produce large litters in a relatively short period of time.

Inertia - a failure of the uterus to contract most often occurring part way through farrowing and is more likely to occur in older sows or sows/gilts in extreme body condition (either too fat or too thin).

While the majority of piglets are born head first, you'll see that towards the end of farrowing, more piglets will be born with their hind legs (or back legs if you prefer!)

Sows can give birth to litters up to twice a year. Newborn piglets are still attached to their umbilical cord and it breaks as they struggle and try to walk; if the sow does not object, you can spray the end of the cord with antiseptic or iodine, but due to the length of the cord being a barrier to infection this is not necessary.

The whole birthing process takes between three and six hours (range: one to 10 hours). At this late stage of gestation, loss of piglets is fairly uncommon.
