Fencing for Pigs ~ Which Type Is Best for Your Farm?

If you intend to raise pigs, you will need fencing for pigs on your farm. There are several reasons why this is important. For starters, even the most domesticated pig breeds can go feral when left to roam freely on the land. Another, and more important reason, is that some states forbid free-ranging pigs.

Even though states like California have strict laws on just how much space you can designate for your pigs, letting them roam as far and wide as they lack is illegal in many others.

Besides, it’s only good farm ergonomics to keep the farm animals contained within a shelter. Not only is this done for their protection from predators, but it’s also paramount to their management regarding food, breeding and socialization.

There’s no doubt that fencing for pigs is important. The question remains: what kind of fencing is good for your pigs and your farm in particular?

Reasons for Pig Fencing

Before deciding which fencing for pigs is right for you, you should know a few things about pigs. For starters, they are gifted escape artists. Pigs are highly intelligent creatures who seek ways to get out of their enclosure.

On the plus side, if you provide your pigs with everything they need within their pasture, they’ll hardly ever find a reason to leave it. Here are just a few reasons pigs might want to escape a pasture:

  • They don’t have enough food
  • They don’t have enough space to roam
  • The pasture doesn’t have adequate fencing
  • They don’t have enough water
  • They are curious about what else is out there
  • They feel threatened in their own home

You will often find that pigs escape their fencing by chance. They were probably rooting for something by the fence line, and they got free while digging under the fence posts. These pigs always find their way back to the pasture, but this always poses a threat, especially if your farm is near a populated area.

Knowing what pigs eat can help ensure they don’t escape their pasture to find more food.

What to Consider

There are some factors you need to consider when deciding which kind of fencing you need for your pigs:

  • How many pigs do you intend to keep?
  • The size of your farm
  • How often do you intend to move your pigs (this needs to be done often as pigs tend to create a great deal of stench, especially if they stay in the same pasture for too long)?

Types of Fencing for Pigs

With all this in mind, let’s look at some pig fencing options available today.

Permanent Fence

If you are raising pigs on a small farm and have no intention of moving them any time soon, then a permanent fence might be the best option. In that case, there are three main options to consider:

  • Fencing made of woven wire
  • Welded wire fence
  • Hog panels

These options are only economical if you have a small enough farm and don’t intend to keep too many pigs. However, keeping your pigs in such an enclosed space will turn the entire area into mud within a few days.

This kind of pig fencing works best if you intend to use your pigs as rototillers that clear up and turn the ground for other agricultural use later on. The downside is that this could lead to soil erosion or even internal parasites should you leave your pigs in the same spot for too long.

Farmers with limited space on their land would benefit most from permanent fencing. This way, the pigs on your land would only need about 10 square feet of space for each.

If this is the path you choose, you can use a wide variety of fence posts, including metal posts and wooden posts that have been treated for rot.

Since pigs can’t jump, your fence height won’t need to be that high. Around three feet should be adequate to keep the pigs fenced in. You must ensure that the fence posts are securely posted to the ground so the pigs can’t root underneath them.

Electric Fence for Pigs

If you are raising pigs in a large pasture, you might want to consider electric fencing. As mentioned, pigs are excellent escape artists but also quite smart. This means that they are probably going to test the kind of boundaries you have in place. A pig will quickly learn to respect an electric fence and refrain from trying to break free.

An electric fence, particularly a three-strand electric fence, is the best option if you have a large piece of land and would like to give your pigs some room to roam. There are several advantages to this:

  • The domestic pigs have more room to find food within the pasture
  • They won’t stink as much since they won’t be enclosed in a small space
  • You get to have a large parcel of your land fertilized by the hogs

Furthermore, a three-strand electric fence wire is cost-effective to maintain. The three-strand electric wire fencing is a great containment measure as your pigs won’t be able to root under, walk through or even jump over the fence to escape. They’ll know to stay away from the hot wire.

Electric Netting for Pigs

If you plan on raising young piglets on your farm, you will be better off using electric netting. While this fencing is ideal for piglets, it’s almost useless for larger pigs as they can easily run through it.

It should also be noted that this kind of perimeter fence will be useless against wild boars, wild pigs, feral pigs, and any larger feeder pigs that might want to get to the piglets. So, this kind of fencing is not for protection so much as it is for containment.

Apart from containment, this kind of fencing material is a great introduction to electric fencing for young piglets. By the time they get old enough to forage with the other pastured pigs, they know what an electric fence looks like and respect it enough to stay within its bounds.

The best part is that electric fence kits are easily available at a reasonably affordable rate. You are, however, advised to use a professional installer when dealing with electricity.

Tips on How to Pig-Proof Your Fence

Whether you use barbed wire, hog wire, chicken wire, or high tensile wire to fence your pig pen, you should know that pigs are very smart and will test it. You can do a few things to pig-proof whatever kind of perimeter fence you put in place against your ever-curious pigs. These include:

  • Inspect the fence regularly: This is true for any fence, but it is especially important for electric fencing. Look to see if any sections are shorted out
  • Look for rooting: If you have used woven wire, hog panel fencing, or welded wire, you need to keep an eye out for spots that have been rooted up, as these may be exit points for the pigs or entry points for feral hogs
  • Use the right energizer: If you are keen on using electric fencing, ensure that you have the right energizer (at least two joules, even though six joules will work perfectly fine despite being a bit more expensive)
  • Dig a trench beneath the fence: This is to keep your pigs from rooting underneath the perimeter fence. You can reinforce this trench with chicken wire or even concrete

These are just a few tips and tricks to keep your pigs fenced in and contained within the pasture. Remember, you will probably need to move your pigs occasionally. Keeping that in mind will help you choose the most practical and cost-effective fencing option for your farm. Raising various pig breeds can add value to your farm or homestead.
