Controlling Pigs With Electrical Fences
Electric fences are an increasingly popular form of animal control. Using electricity to deter
animals from crossing a boundary; these types of fences can be effectively used to contain
domestic and livestock animals. Many pig owners are turning to these fences as opposed to
traditional fences for the many benefits they offer.
Electrical fences are ideal for containing pigs because:
It is safer than traditional fencing;
Electric fences are more affordable and cost effective than traditional fencing;
It requires far less maintenance;
They are easy and quick to erect and collapse as required, which consequently allows
strip grazing to be possible.
Many people use electric fencing for pigs effectively. Pigs have very little hair on their bodies
and soon learn the consequences of trying to pass the wire. They are intelligent animals and will
quickly learn to respect the fence.
Consisting of 4 components, electrified fences should have:
An energizer generating regular pulses of electrical current,
One or several wires to transport the current,
Plastic insulators preventing the current from branching off into the ground,
An energizer which is earthed as deep as possible in the soil where it is most moist.
In order to safely contain pigs you will need an energizer with a minimum of 3,000 volts on the
fence line and, depending on the length and layout of the area, a minimum of 1.5 stored joules.
However this can depend and be affected by vegetation within the area, the length of the fence
and the type of wire being used. It is recommended that three lines of tensed wire supported by
posts are usually sufficient to contain pigs, and that vegetation is kept to a minimum on the fence
If you are keeping piglets with the pigs, it will be important to space the wires closer together,
but also lower to the ground than you would if you were just controlling adult pigs.
