Why pigs need a training fence, not just a fence
Pigs meet the world nose-first, and a pig that touches an electric wire tends to surge forward through it rather than back away — the opposite of what you need. Respect for electric fencing is therefore a trained behaviour, not a property of the wire. A pig that has learned, in a small safe area, that the tape bites and never pays to challenge will treat a single strand across a whole field as a wall. A pig whose first meeting is a faint tickle through a dry snout in a big pasture learns the opposite lesson: fences are negotiable.
Set up a training pen that teaches clearly
Build a small training pen inside a secure physical fence — stock netting or pallets — so a pig that does push through its first shock is still contained. Run two strands of highly visible electric tape or polywire, one low at rooting height and one at mid-body, and mark them with strips of bright tape for the first week. Visibility matters: the pig should learn to recognise the thing that bit it, so it can avoid it deliberately ever after.
Make sure the energiser earns respect. Use a charger rated well beyond your fence length, ground it properly with adequate rods in moist soil, and keep vegetation off the wires. A weak, grassed-out fence teaches pigs to test it daily. Wet ground teaches best, so if you can, train new pigs when the soil is damp rather than in the middle of a dry spell.
The first lessons, step by step
Put the pigs' feed and water well inside the pen, and let them discover the wire themselves while investigating; a nose touch on a live, obvious tape delivers the lesson in one moment, with no chasing or forcing from you. Most pigs need only one or two touches. Stay nearby the first day: a pig that panics and runs through needs the physical backup fence, a calm reset, and another chance to meet the wire nose-first rather than at a gallop.
Keep the pigs in the training pen for several days, feeding near but not on the wire, until you see them grazing up to the tape and turning away without touching it. Only then move them to the main electric-fenced area, and re-flag the wire there for the first few days so they recognise the boundary in its new setting.
Keeping respect for the fence long-term
Respect decays when the fence does. Check the charge regularly, clear fallen branches, and never let pigs spend a day discovering the power was off — one uncharged afternoon can undo the training, because pigs retest boundaries constantly. Keep feed, water and the wallow comfortably inside the boundary, so the fence is never between a pig and something it badly wants, and be careful with a boar or a sow in season near pigs on the other side: motivation can outbid one remembered shock.
Pigs that learn to rush the wire at speed, taking the shock as the price of exit, are made, not born — usually by a weak training fence. Retrain a rusher in the small pen on a strong charge rather than adding ever more strands out in the field.
A routine everyone can keep
Fence checks belong on the daily round, and KinsLe's Care Teams lets you set the charger check and wire walk as recurring duties for your pigs, marked complete with a timestamp, so a missed day shows up before your pigs find the gap themselves.
