For those of you that run electric fencing for pastured hogs, how high off the ground are the wires and how many do you use?

Well trained (to electric fence) hogs over 150 lbs only need a single wire about standing nose height. The key here, though is TRAINING. Don't expect to just put them out and turn them loose and have the wire contain them. Won't happen. Introduce the wire in a pen with solid sides, and let them get stuck between the wire and fence a few times. They have to learn to back up when shocked rather than run forward. We put ours out in the woods when they are around 75-100 lbs (depends on season) with 2 wires. If the ground is nice and moist, both wires are hot. If the ground is dry, you will want at least one ground wire. You could even do 3 wires if necessary. We don't really trust them to one wire until they are over 150 lbs in our terrain. If you are dealing with perfectly flat terrain, you might be able to go smaller. Our is rough though, with lots of dips and changes where a little pig could duck under. Extra wires are critical until they are big enough to bump it no matter where they go under. Hope that helps.

I use step in fiberglass posts, I run the wire on the bottom 2 clips. I am not sure of the exact distance but you want one at snout level and one near the ground to get their attention when they root up to it

As has been recommended above, two strands. The lower is approximately six inches off the ground, and the higher about 16-18" off the ground. Using T posts for corners, or anywhere your fence makes a change of direction, and then step in posts for inline support gives us the best result. We use polywire, rotating regularly.

Train them when they're little inside hog panels. After that 1 wire is enough if it's got any zap at all to it. In fact we have more issues trying to get them past the old wires location when moving them than with them ever getting out.

I always found it interesting that it is nearly impossible to drive a hog out across the line where the hot wire has been but let the battery fail and they will be in your garden immediately. I think it has to do with Murphy's law of pork production. Come to think of it I think Murphy may have been a hog farmer. :)

So pretty much what I thought. I'm hoping to get a training wire run around the pen today or tomorrow. They're not little things - around 100-125. I'll see if you can teach old hogs new tricks, lol

Hogs fascinate me and creep me out a little. I dispatched a rooster this morning after he attacked me. Threw the body to the hogs. They were unsure at first, but we're super enthusiastic once they figured out it was food. Later on, one was up against the fence wanting his back scratched and had a chicken foot hanging out of her mouth. Yikes!

I used to have hot wires all around my cattle pens. That is where all the new hogs went for 2 weeks then they were turned out in just hot wire pens. I didn't have very much trouble keeping them. Had some 4 foot wood gates for the hot wire pens so you could drive them out or lead them with a feed bucket if you walked fast. hot wires were about 16 inches off the ground. fencer was real hot had about 1/2" of spark.
