Pigs are social animals that typically live in groups. However, like any social animal, they can display aggressive behavior toward one another. Pigs may attack each other for several reasons, including competition for resources like food and water, overcrowding, boredom, and mating season.
Understanding why pigs attack each other is important for farmers and pig owners to prevent serious injuries and promote harmonious group living. In this article, we will explore the different reasons for pig aggression and how to prevent it.

Do Pigs Attack Other Pigs?
Yes, pigs do attack other pigs, and this behavior can be a concern for farmers and pig owners. Aggression in pigs can range from mild biting and pushing to more severe attacks that can result in injuries or even death.
It is worth noting that aggression is not uncommon in social animals, and pigs are no exception. However, excessive aggression can be a sign of poor management or inadequate living conditions, and can have negative consequences for the health and welfare of the pigs involved.
Aggression can occur between pigs of the same age or size, but it is more common for younger or smaller pigs to be the target of aggression from larger or older pigs. In some cases, aggression may be related to competition for resources like food and water, especially in situations where resources are limited or of poor quality. Pigs may also become aggressive due to overcrowding or boredom, which can cause stress and anxiety.
While some level of aggression is expected in a group of pigs, excessive aggression can cause injuries that can lead to infection, which can be life-threatening. It is important to identify signs of aggression early to prevent serious injuries.
Why Do Pigs Attack Each Other?
There are several reasons why pigs may attack each other, and it is important to understand these reasons to prevent and manage aggression in pig groups. One of the main reasons pigs attack each other is to establish dominance within the group. Pigs are social animals that live in hierarchical groups, and establishing dominance is a natural part of their social structure. Dominant pigs will often assert their position by biting, pushing, or chasing subordinate pigs.
Competition for resources is another common reason why pigs may attack each other. This can include competition for food, water, or space. In situations where resources are limited or of poor quality, pigs may become more aggressive towards each other. Overcrowding and boredom can also lead to aggression in pigs, as they become stressed and frustrated.
Mating season can also contribute to aggression in pigs, especially among males. During this time, males may become more territorial and aggressive towards other males in the group.
It is important to note that while aggression is a natural behavior in pigs, excessive aggression can be a sign of poor management or inadequate living conditions. Factors such as overcrowding, poor nutrition, and lack of environmental enrichment can increase stress and anxiety in pigs, which can lead to aggressive behavior.
Is It Normal for Pigs to Bite Each Other?
Yes, it is normal for pigs to bite each other, as it is a natural part of their social behavior. Pigs are social animals that live in hierarchical groups, and establishing dominance is a natural part of their social structure. Dominant pigs will often assert their position by biting, pushing, or chasing subordinate pigs.
However, it is important to distinguish between normal social behavior and excessive aggression that can result in injuries or even death. Mild biting and pushing are expected in a group of pigs, and these behaviors are usually resolved quickly without injury.
Excessive aggression, on the other hand, can be a sign of poor management or inadequate living conditions, and can have negative consequences for the health and welfare of the pigs involved. Factors such as overcrowding, poor nutrition, and lack of environmental enrichment can increase stress and anxiety in pigs, which can lead to aggressive behavior.
How Do You Stop Pigs from Attacking Each Other?
Managing aggression in pig groups is important for promoting the health and welfare of the animals involved. Here are some strategies for preventing and managing aggression in pig groups:
Provide Adequate Space
Overcrowding can contribute to stress and aggression in pigs. Providing adequate space for each pig can help to reduce competition for resources and prevent aggressive behavior. The amount of space required will depend on the size of the pigs and their housing environment, so it is important to consult with experts and guidelines to ensure that the pigs have enough space to move around comfortably.
Provide Adequate Nutrition
Poor nutrition can also contribute to stress and aggression in pigs. Providing a balanced and nutritious diet can help to reduce stress and promote good health, which can in turn reduce the likelihood of aggressive behavior. It is important to consult with experts and guidelines to ensure that the pigs are receiving the appropriate diet for their age, weight, and breed.
Provide Environmental Enrichment
Environmental enrichment can help to reduce boredom and stress in pigs, which can in turn reduce the likelihood of aggressive behavior. Providing items such as toys, straw, and rooting material can help to keep pigs occupied and engaged, and provide them with opportunities for natural behaviors such as rooting and exploring.
Separate Aggressive Pigs
If a pig is exhibiting excessive aggression towards other pigs, it may be necessary to separate them from the group. This can prevent injuries and promote harmonious group living. Separating a pig may involve providing them with their own space or housing them with pigs that are more compatible with their temperament.
Monitor Pig Behavior
It is important to monitor pig behavior regularly to detect signs of aggression early and take appropriate action. Signs of aggression may include biting, chasing, pushing, or mounting. Observing pigs during feeding times, when resources are most contested, can be particularly helpful for identifying potential aggression.
Provide Adequate Veterinary Care
Pigs that are in pain or discomfort may exhibit aggressive behavior as a way of expressing their discomfort. Providing adequate veterinary care, such as regular check-ups and treatment for any injuries or illnesses, can help to reduce stress and prevent aggressive behavior.
What Are Signs of Aggression in Pigs?
Pigs are social animals that have complex social hierarchies, which can result in aggressive behavior towards other pigs in the group. It is important to be able to recognize the signs of aggression in pigs in order to prevent injuries and promote harmonious group living. Here are some common signs of aggression in pigs:
Biting
Biting is a common sign of aggression in pigs. Pigs may bite other pigs as a way of establishing dominance or as a response to a perceived threat. Bites can range from minor to severe, depending on the intensity of the aggression.
Chasing
Pigs may chase other pigs as a way of establishing dominance or asserting their territorial rights. Chasing can be a precursor to more aggressive behavior such as biting, so it is important to monitor pig behavior closely.
Mounting
Mounting is another common sign of aggression in pigs. Pigs may mount other pigs as a way of establishing dominance or as a form of play. However, excessive mounting can lead to injuries and should be monitored closely.
Pushing
Pigs may push other pigs as a way of establishing dominance or as a response to a perceived threat. Pushing can be a precursor to more aggressive behavior such as biting, so it is important to monitor pig behavior closely.
Tail Swishing
Tail swishing can be a sign of aggression in pigs. Pigs may swish their tails as a warning signal to other pigs to back off, or as a way of expressing their frustration or anger.
Raised Hackles
Raised hackles can be a sign of aggression in pigs. Hackles are the hairs on the back of a pig’s neck that stand up when the pig is feeling threatened or aggressive.
