Keeping cows, cattle and other livestock safely within the confines of a fence is of critical importance to farmers and ranchers. Although there are many solutions, the electric fence has proven the most effective. To contrary belief, barbed and woven wires can be harmful and more expensive when it comes to corralling livestock. Electric fencing is the most cost-effective, safe and easy-to-maintain solution for protecting your cattle. Weeds and the condition of the earth can impede the flow of electrical current.
