A first time mother can labor anywhere from four hours to 15 before the first pig arrives. Sometimes they can take all day to give birth to all piglets, or sometimes they can all arrive within an hour! Just like people, it depends on the individual. If there are no anatomical problems, a birth can usually take anywhere between 6 hours and 10 hours while some can be as short as an hour and a half. It depends on the individual. Some sows get quiet and calm, and give birth quite rapidly. Some have a lower pain tolerance and they may get up and get restless and take longer. The first stage of labor is nesting and rooting around, making a 'nest' and this may be a all-night process. The actual laboring and contractions takes less time. I'd say for us its been an average of six hours overall. If a sow stops having piglets at the present rate, then perhaps there is a pig in a bad position or she needs oxytocin, a naturally ocurring hormone that they induce labor in humans with.
When my rabbit was pregnant, we didn't even know that she was pregnant. When we found out she had given birth, which was some minutes after she gave birth, she was in the middle of constructing her nest. So my guess is, they build their nests a little while before or immediately after giving birth.
