Hey there. I raise american guinea hogs and have seen many pregnant pigs and birth. The milk bar is usually the best indicator of impending birth. It'll look like 2 bars under her stomach. Once it gets big and hard, she's close. They usually start streaming milk right before and during birth. Pigs have been one of the easiest no fuss birthers Ive had. I put a pile of straw or hay in for the mom to into a nest. Not too much where the babies get burried. I don't separate but it's not usually necessary with agh. They all help care for piglets. Feed is sow and piglet. Free choice if you can manage it. Nursing takes a ton out of them. Watch piglets can't get into water and drown. They'll need water and starting eating feed around 2-3 weeks. Don't worry about docking tails or clipping teeth. It's not necessary outside factory farms. First time mothers can be very nervous after giving birth. A couple of dark beers will help her relax and nurse. They can also be extremely protective the first couple weeks. Like try to bite you protective. Watch her body language and listen to her if you need to go in the pen. I've had some that didn't care what I did with their piglets and others that cared very much. I use a big net from the other side of the fence if I need to grab a piglet. Also, if they are on dirt they don't need an iron shot. If they are inside or on concrete, they need an iron shot.
