Anyone try some electric cattle fencing inside the trap to keep them away from the sides of the trap? Might not stop the first panic charge but after they settle down a little and wander over to the fence and get a good shock? Maybe they'd just tear it up? Just wonderin

I would think they would just tear it to shreds with the first panic, once its grounded its no Bueno.

yup....

I agree with redchevy, but there may be a way to make it work. Others will let us know whether its practical.

Could you install a predator wire at the bottom of the panels and lift the panels about an inch off the ground, put a rubber buffer between the panel and post, and hook up the panels to a truck battery?

Been there, tried that.
Spend your money on the better pig panels, more posts and use the galvanized electric fence wire as tie wire and tie the heck out of panels and posts.
Pigs tend to go absolutely bat-[censored] crazy when they hit electric fence.

Interesting to hear someone who's tried it I guess I can imagine what it would look like with a dozen pigs hitting the wire. OK bad idea.

It's an interesting idea, and thinking about new things is great. However, in this case I agree that efforts to simply construct a stronger trap would probably offer better return on your effort.

Just electrify the pen/trap itself. You could put a switch or contact on the door so that it only electrifies once the door has been dropped. I'm no electrician, but it makes sense in my head. Ha!
