Building a corral can be a lot of work, and there is nothing worse than finishing and learning that your cattle destroyed it on the first or second use. Therefore, any time you build a pen or corral, it should be with resistant and stable materials.
Portable cattle panels, for example, are made of metal and can last for 20 years or longer. This means that your corral should last that long.
It is possible for the metal to rust, but it generally stands up better to the elements and the cows than other materials. This is especially true if you have a particularly temperamental or large breed in your herd.
You can use both permanent and portable metal cattle panels. Permanent corrals are obviously sturdier but would be a headache to move later. However, they are also quite a bit quieter and tend to be less expensive than a portable system.
Portable cattle panels give you the freedom to set up wherever is most convenient for you and can even be moved to a new ranch or farm if you need to.
Wood can also be a good choice, but it has to be a very resistant wood and done the right way for it to last. Also, using wood is softer on the cows, so they don’t have as much potential to be damaged if they hit it.
In order to be strong enough to resist more challenging animals, wood should be secured in the ground with concrete. Unfortunately, this makes it so that it is not a portable option.
It can also be prone to rotting or breaking if you aren’t careful in maintaining it. However, wood fencing and corrals are the more traditional method and have a rustic look, which is important to some ranchers.
