Pig Fencing

Electric fencing is ideal for containing Pigs:

  • safer than conventional fencing
  • can be easily moved for grazing
  • costs less than conventional fencing
  • they will respect the fence quickly
  • simple also to electrify an existing fence

Electric fencing is a cost effective and excellent way to contain pigs. Commercially reared pigs are very easy to control with electric fencing as they have very little hair and large wet noses so will they will feel a strong shock. The are intelligent animals and will very quickly learn to respect an electric fence.

Electric fencing can be used to contain them in whole fields or parts of fields for strip grazing. For permanent fencing wooden posts and screw in insulators with poly wire and ideally a mains energiser can be used. For temporary fencing 3ft poly posts, poly wire and a portable 12v energiser should be used.

Wire and post spacing is important when installing a pig fence. For normal strip grazing and permanent fencing 3 wires fairly equally spaced with a total height of 60cm are fine. If you are fencing piglets than more wires with closer spacing at the bottom are needed. Please ensure that the ends of the fence well strained and anchored. Please find below a diagram of the different vertical spacing of wire fencing:

The fence lines recommended for use with sheep is poly wire and galvanised wire. Three strands of wire provide good visibility and coverage with one at above head height at 60cm, the middle one at nose level at 35cm and the bottom line at knee level 15cm from the ground. 3ft posts can be used or if you have smaller breeds of pigs smaller electric fence posts can be used. When using electric fencing with wires close to the ground it is important to trim the vegetation to keep it off the fence as this will affect the voltage on the fence.

Reel systems are sometimes used with pigs as the fencing is can be moved around alot and this enable quick unwinding and winding of the fence. Reel mounting posts are used to hold the reels. Usually a mix of metal mounting posts, corner posts and poly post are used in a pig electric fence system.

Electrifying an Existing Fence

You can easily adapt or convert an existing conventional fence into an electric fence. This is a cost effective method if you already have a permanent fence in place. You can either use the wooden posts already installed and put in insulators on the posts with wire. There are also many types of offset screw in and post top insulators for mounting on an existing fence.

Energisers

Pigs require a minimum of 3,000v on the fence with an electric fence energiser that has at least 1.5 Joules in stored energy. For fences that are permanent or if a mains supply is available using a mains energiser is the best option. A mains system works by plugging the energiser into the supply inside and running lead out cable to a 2m earth stake and to the fence to power it. For permanent fences mains energiser should not have less than 0.5 Joule stored energy. For remote areas or places you cannot get a mains supply to, 12v, 9v or solar electric fence energisers should be used. 12v battery energiser are usually used and we would recommend using these as they are more reliable and cost effective. If you are likely to use the energiser just for strip grazing or will be moving it around alot than 9v energiser are better as they are lighter and easier to move.

Fence Line Conductor

We would recommend only using poly wire, stranded wire, galvanised wire and high tensile wire for use with pigs. Electric poly wire gives great visibility and can be easily unwound and wound up for re-use. Also stranded wire can also be re-used for temporary fencing. If you are installing a permanent fence its better to use either high tensile wire and or galvanised wire as this is longer lasting. There is different quality of conductors lines available. A quality of a line is dependent on the number of conductors, diameter of conductors, level of resitance and breaking strain. Stranded, galvanised and high tensile are all conductor so you are usually looking at the level of resitance and breaking strain for quality. A poly wire with alot of large conductor wires with low resistance and a high breaking strain has the best quality. For longer electric fences you will need a better quality line such as galvanised wire but if it is just a short fence the cheapest lowest quality will be fine. 

Pig Fencing Kits

We offer a starter pig electric fence kit that gives you an energiser, earth stake, electric fence posts and wire, gate handles, signs and a fence tester. As normally large lengths of fencing can be needed if you may need to add to this kit. Systems will normally contain an energiser, earth stake, reel mounting posts, reels, poly posts and wire. If you need a system please contact us with the length of the fence needed and we can quote you for all you need.
