Why Do Pigs Like Mud?

We’ve all seen a little pig rolling around in the mud and loving every second of it. But the question comes up “why do they do it?” Many people think that it’s because pigs are dirty animals. This is not the case, pigs are actually very clean animals. In this article we dig in to why do pigs love mud.

They loved to be covered in something

Pigs love to covered in something at all times. This typically is mud however if mud is not available they will try and cover themselves in whatever they can find. The reason behind this is simply because it helps them avoid sunburns. Many pigs (especially your pink varieties) can easily sunburn. And if you’ve ever had a sunburn and couldn’t get out of the sun you know how bad it hurts. So they will cover themselves in whatever they can find to help protect their skin. As I said before, many people think that pigs are dirty animals. This is not true at all. If you have ever spent any significant time around a pig farm then you probably will notice that they keep their “bathroom” as far away from their eating and drinking area as possible. You can watch them root around in mud for hours and it’s quite entertaining to watch.

Thermal Regulation

Pigs and hogs have very few sweat glands in their bodies. So, unlike humans they are unable to sweat when they get too hot. So to help keep their bodies at a cooler temperature they will roll in mud since the moisture helps keep it cooler for a longer period of time. Nowadays many pig farmers use misters or sprinklers to keep the animals cool. The problem with this is that pure water evaporates much faster than the water in mud does. Our hogs typically will lay in a mud hole the majority of the day if they can. We don’t discourage the practice, in fact, we encourage it. We want our animals to be as natural as they can be which is why we keep them in dirt and not concrete pens.


When a pig is covered in a nice thick layer of mud it helps discourage bugs from biting them. Since typically there is a fair amount of food around them it tends to attract flies and other pests that irritate the pigs skin. By covering themselves in mud they give themselves a barrier against those kinds of pests.

So now you can tell somebody the answer when they ask “Why do pigs love mud?” I also did a video on this exact topic on YouTube which you can watch below. Feel free to share this article if you found it informational or helpful.
