Pigs are often seen rolling in mud, and there are several reasons why they exhibit this behavior:

Thermoregulation: Pigs don’t have sweat glands like humans do, making it difficult for them to regulate their body temperature. Rolling in mud helps to cool them down through evaporation. The mud acts as a natural barrier to the sun’s heat and also helps in retaining moisture on their skin, which cools them as it evaporates.

Sun Protection: Pigs have relatively thin skin that can easily get sunburned. Rolling in mud provides a protective layer that shields their skin from the sun’s harmful UV rays, helping to prevent sunburn and other skin issues.

Insect Repellent: Mud can act as a natural insect repellent. Pigs rolling in mud can create a layer of mud on their skin that deters insects and parasites from bothering them. This can help reduce the risk of bites, infestations, and skin irritations.

Social Interaction: Pigs are social animals and enjoy interacting with each other. Rolling in mud can be a communal activity where pigs bond, play, and establish social hierarchies. It’s a way for them to engage in social behaviors and reinforce their relationships.

Behavioral Instinct: Pigs have retained some of their wild instincts even in domesticated settings. In the wild, pigs would dig for roots, tubers, and other food items in the ground. Rolling in mud could be an extension of this behavior, helping them to find food and stay cool simultaneously.

Sensory Experience: Rolling in mud provides pigs with a sensory experience. Pigs have a well-developed sense of smell and touch, and mud rolling might offer them a pleasurable sensory stimulation.

Comfort and Comfort Marking: The sensation of mud on their skin might also be soothing and comforting to pigs. Additionally, the mud rolling can leave scent markings, allowing pigs to leave their own unique scent behind as a form of communication with other pigs.

It’s important to note that while pigs do enjoy mud rolling, they don’t necessarily prefer dirty or unsanitary conditions. In fact, domesticated pigs are often provided with clean, shaded areas, and opportunities to wallow in mud are typically managed to ensure their health and well-being. Mud rolling is just one of the many behaviors that reflect the natural instincts and adaptations of pigs.
