Any animal that weighs over 1000 pounds and has a lot of strength should be kept in an electric fence. These fences are the best way to keep your bulls from escaping and causing potential damage to your property. In this article, we will discuss how electric fences work, as well as which ones are the best for bulls.

Which electric fence is right for me?

Each animal that is protected outdoors by an electric fence has specific requirements for the pasture fence system. The following factors must be individually designed for the animal and the external circumstances or taken into account when choosing the device:

  • The hairiness of the animal and its conductivity in order to transmit a targeted and effective but not too high a current pulse to the animal.
  • The size of the animal
  • The fence length – so that the power reaches everywhere
  • Overgrowth along the fence will weaken the output

How to Install Electric Fence for Goats

A distinction is made according to animals to be herded:

Easy to herd animals such as horses, cattle, pigs, dogs, cats.

Here a normal electric fence is sufficient. These animals are often used to an electric fence, have shorter fur, and therefore feel the current impulse clearly. Nevertheless, the minimum herding voltage on the fence should be over 2000 volts (3000V is better) – otherwise, the animals tend to break free.

Animals that are more difficult to herds, such as free-ranging wild animals, sheep, goats, and poultry

For this purpose, choose a powerful electric fence unit, as these animals are usually not used to electric fences and also have thick coats. These animals are rather insensitive to electric shocks. Here only a pasture fence with sufficiently high voltage can provide the necessary herding security. This voltage should be above 4000 volts.

You can use the following specifications as a guide:

Pasture fencing devices with low pulse energy (less than 1.0 joule)

  • Easy to herd animals
  • Small fences
  • No to little vegetation

Pasture fencing devices with medium pulse energy (up to approx. 5.0 joules)

  • Hard to herd animals
  • Medium fence lengths
  • Normal to medium vegetation

High pulse energy fencers (over 5.0 joules)

  • Hard to herd animals
  • Long/very long fences
  • Heavy vegetation

Fence height

For a herd-proof electric fence for cattle, you need at least 2 fence rows. Depending on the risk, more fence rows may be required.

For cows, we recommend 2 fence rows in the heights of approx. 23.6 and 35.4 in. For bulls, suckler cows with offspring, and robust breeds we recommend 3 fence rows in the heights of approx. 17.7 in, 29.5 and 41.3 in.


When purchasing an electric fence for bulls, you need to take into account the height of the fencing and also whether it is able to contain bulls.

You should avoid placing energy-saving devices near your herd because they are not suitable for herding animals.

If you want a low-maintenance fence, keep in mind that this may reduce its ability to contain cattle or other livestock. A high voltage wire will give more pulse strength than a single wire but can be expensive compared with using two wires at lower voltage levels.
