Training pigs to electic

So... I live on 20 wooded acres. Today I bought two 7 week old kune kune gilts. My dream is to have them rotationally grazing my woods clearing out underbrush and building a silvo pasture (my land was logged about 5 years ago but still has lots of huge oak, maple, beech, and cherry trees). I'm working on a perimeter fence and plan to divide the land into 5 acre quarters (and eventually into 2.5 acre eighths) to begin the de-brushing.

My question is: this is my training pen. Am I doing this right? I've never had success with electric except for netting with pigs- they just run through it. But I hear people rave about electric working for pigs once they are trained. Sorry for the blurry pictures- all I have is a camera on my phone. In case you can't see what I've got- it's a woven wire fence with a strand of electric about 4" off the ground about 6" off the woven wire fence. So far my pigs run into it constantly and seem to think I'm the one hurting them (but it's only been like 3 hours and they're new here and scared). They ran through the front where the netting is a few times and I put up the netting and now they aren't messing with it. Will they learn to respect the electric alone, or will they realize they can run through it as soon as the electric isn't backed by netting or hard fence?

Electric is really my only realistic option for perimeter fencing here, so whether or not the pigs respect it will determine whether I have a goat farm with a couple of pigs in a pen or a pig farm with a couple of goats. What are my chances, and please throw any advice my way on how to make my set up better/ pig tight.

Hi Anna;
Give them some time to calm down. They have had a rough day...
Taken away from mom & siblings. Loaded in a crate and driven in a vehicle.
No more milk from mom... life sucks for them today!
Kune Kunes are generally  mellow piggy's. Give them a home, fresh cold water, plenty of treats and they will come round!

What I do for savvy critters like goats being kept in and deer being kept out is to bait the fence! Hang little tags of aluminum foil on the wire at nose height of the critter in question and put a little dab of peanut butter on there.  Critter will smell this and give it a lick and get a REALLY good shock!  I've had deer respect a single wire for months this way!
