Did you guys keep sows year after year that were big enough to to not be able to go under the fence, and their piglets stayed near their moms and didn't get out? Or did you start each year with piglets, and the fence was really, really close to the ground?When I was a kid we raised hogs on 5 acres with just 1 strand of hot wire. You put it at nose level, they lead with their nose. Dad made it hot enough that it left a mark when they touched it. They learned real quick not to go anywhere near that wire. They learned so good that he had hell at times trying to get them into new pasture because they knew where that boundary was and would not go past it. My dad done daily walk arounds just to make sure weeds weren't getting into it. I remember that wire real well myself because i'd go to step over it and I still swear to this day that thing would reach out and grab me, LOL. I can still feel that wire biting me. It was not fun and it would leave marks on my legs too. The only times we had hogs escape was when the wire went down to storms causing trees or limbs to fall on it. Which thankfully, wasn't all that often. But we never overwintered them, they always went to market in the fall and we would butcher a few for us and family members.
