What Is an Electric Fence?
An electric fence applies an electric current to deter living creatures from touching it. This current, delivered approximately once per second, produces an electric shock upon contact.
Touching an electric fence results in a sensation similar to static electricity. It’s generally harmless if contact is brief and the person quickly withdraws their hand.
Uses of Electric Fences
Electric fences are primarily used to contain livestock and deter pests. Animals tend to avoid electric fences after experiencing shocks, enhancing the fence’s effectiveness.
Features of Electric Fences
Advantages
Electric fences offer the advantage of controlling the movement range of animals. They can deter wild animals from entering certain areas and confine livestock to designated grazing zones.
Disadvantages
The primary disadvantage of electric fences is their cost. This includes both the financial investment and the need for regular maintenance checks.
How to Choose Electric Fences
Selecting the right electric fence depends on its intended use and the target animals. Consider the following when choosing an electric fence:
1. The Perimeter of the Field
Consider the size of your field and ensure the wire length can fully enclose it. Account for any unique terrain or steps, and choose a wire length that accommodates these features, including the required fence height.
2. Target Animals
Select fence posts suitable for the target animals and ensure you have the necessary wire-fixing devices. The positioning and height of the fence posts should be tailored to the specific animals, as follows:
Wild Boar Control: For wild boars, use posts about 3 ft high, spaced approximately 8 inches apart, with two lines of wire.
Deer Control: For deer, use posts at least 6 ft high, spaced 8-10 inches apart, with four lines of wire.
Anti-Monkey Measures: Against monkeys, use posts over 7 ft high, spaced 8-10 inches apart, with five lines of wire.
Other Information About Electric Fences
1. Installation Considerations
Pay attention to the following when installing electric fences:
Grass Interference: Overgrown grass touching the wire can cause electricity leakage. Regularly trim grass around the fence to prevent hiding spots for animals.
Wire Height: Ensure the electric wire is high enough to prevent ground contact, which could disrupt the electrical flow.
Metal Proximity: Metals near electric fences can accidentally conduct electricity. Avoid placing conductive materials, such as metal, close to the fence.
2. Management During Inactivity
When not in use, electric fences are typically dismantled. Leaving them in place without electricity might make animals less fearful of the fences, reducing their effectiveness. If dismantling is not feasible, keep the electricity on and conduct periodic checks.
