Wire, Posts, And Gates For An Electric Cattle Fence
Decide how many wires are going to be on the fence – one, two, or five. The bottom wire should be 22 inches (55cm) from the ground and the top wire 49 inches (125cm). If you plan on keeping bulls, the fence could be up to 40 inches (152cm) high.
A short zap of electricity from an electric fence will not harm your cattle. It will hurt for a moment, and the memory will last, hopefully, long enough to dissuade them from returning to the fence and trying to get out!
