Electric fence is the most effective form of livestock control for one very simple reason. It offers the same kind of natural emotional response that large animals are accustomed to in the herd environment. In other words in every herd of large animals there is a pecking order. The genetically dominant animals in many cases, regardless of size, become the accepted leader. The lessor animals of the herd respect that position. When an animal with a lessor social position challenges the dominant authority they are met with an immediate and sometimes violent response. Electric fence treats these animals in a manner that they naturally respect. A shock from a low impedance fencer is quite intense and establishes the same emotion in the animal as if it were kicked or bitten by the herd boss, but without potential injury.
