Electric Fence:
This type of fence can be used as an inexpensive  portable or temporary fence  for horses, sheep, cattle and other livestock. It can be built as a permanent fence system and  is also a  cost-effective fence to exclude deer, elk, moose, caribou, bear, coyote and other animals from crops, airfields and highways.

There are two types of electric fences; temporary and permanent. Both require a fence controller to energize the fence.
