Pigs lift things with their noses and easily throw gates off their hinge hooks. This is an instinctual behavior – there is no particular intelligence about it. They stick their noses in low openings and lift. It’s rooting.
It’s a problem with gates. The solution is quite simple. Electrify the gate. The wooden or stone post acts as an insulator and the hot wire from the nearby fencing delivers a charge to the gate through the red switch. The result is if a pig starts poking at the gate it gets a shock just like if it were to poke around at the electric fencing.
The other thing that helps is a pin in the pin of the hinge of the gate. This slows the pig from lifting the gate off of its hinges so it gets a chance to feel the fencer’s charge on its nose. Be sure to open the switch before you open the gate.
Electric fencers are safe as long as you can get away from them. That’s the design. They deliver a very brief pulse, less than a 1/10th of a second spaced out each second. That pulse is low current which makes it safe but it is high voltage up to 10,000 volts which makes it be able to jump across a gap and fur or hair. This is what pushes the pulse out through our miles of fencing. Voltage hurts. Current Kills. Joules are in reserve.
Contrary to the mythology, pigs can be herded through gates that were previously electrified. They just need to be able to clearly see that the gate is open. It works fine for us with both the swinging gates, drop gates and polywire gates on handles.
