Old Fences Made to Last
Old fences can be made to last for many more years by simply attaching offsets and electrified wire on one or both sides - even where fences have deteriorated so much they need replacing.
New fences will last almost twice as long if they have electrified offset wires attached to them. Electrifying one or more wires in a conventional nonelectric fence will prevent stock pushing through the fence.
Attach single offset wires at two thirds the height of the animal to be controlled. If sheep and cattle are to be in the same area, use two wires or a single offset attached at three quarters of the height of the sheep.
Where old barbed wire is rusty and broken, remove the worst wires and tighten the others to prevent an ongoing problem of them shortening out the offset wire. Barbed wire should never be electrified.
