Pigs are domesticated mammals reared as livestock. They are also noted for their intelligence. But pigs are also perceived as aggressive. How aggressive are pigs in reality?
Pigs are not naturally aggressive animals. They are quite docile and calm creatures. Certain environmental and management factors can increase aggression in pigs. Proper handling and management can prevent or reduce aggressive behavior. It is important to address aggression right away.
Read more about the topic to grasp better how aggressive pigs can be and the factors contributing to their aggression.
Natural social behavior of pigs
Pigs are social creatures, establishing elaborate social hierarchies within their herds. These hierarchies, or “pecking orders,” are based on characteristics like size, strength, and age created by interactions between people.
The dominating pig, often known as the “alpha,” is typically the biggest and sturdiest member of the herd and has the greatest clout. The dominant pig in the herd typically has early access to food, water, and other resources. It also gets the most attention and grooming from the other pigs.
Additionally, pigs form tight relationships with their family members and frequently remain close to them throughout their lives. Pigs have been seen to demonstrate empathy for one another and to support and console one another under trying circumstances.
Pigs are typically docile creatures who try to avoid conflict. They use a range of vocalizations and body language to communicate with one another. A pig, however, might turn hostile out of self-defense if it feels threatened.
The perception of pigs as aggressive animals
There is a misconception that pigs are hostile creatures. This belief may be based on the fact that pigs are big, powerful creatures that are unpredictable when under stress or threat.
Furthermore, due to the nature of their professions, some farmers and others who breed pigs for meat could have a poor opinion of pigs. It is crucial to remember that rather than being a natural trait of the animal, aggression in pigs can frequently be impacted by environmental and managerial factors.
Factors that can influence aggression in pigs
Environmental factors
Overcrowding
Pigs housed in overcrowded settings may become more aggressive as they battle for space, food, and other resources. This can result in greater hostility against other pigs as well as people.
Lack of space
Pigs who do not have adequate space to walk around and express natural behaviors may grow frustrated and aggressive. This is especially true for pigs raised in confinement systems or small quarters.
Poor sanitation
Pigs housed in filthy settings may become violent as they become anxious and uncomfortable. This can involve exposure to excessive ammonia, dust, and other irritants.
Lack of Socialization
Pigs who do not have regular social interactions with other pigs may become aggressive as they become nervous and anxious.
Unfamiliar settings or new pigs
Pigs may become aggressive when introduced to unfamiliar circumstances or new pigs as they attempt to establish dominance and territory.
Heat stress
Pigs are extremely sensitive to heat stress; high temperatures can make them agitated and aggressive. This is especially true in humid areas.
Lack of enrichment
Pigs not given appropriate environmental enrichment, such as straw, toys, or other materials to root through, may become frustrated and violent.
Improper feeding and management
Pigs not properly fed or handled may become aggressive as they compete for resources.
Genetics and breeding
Pig aggression can be influenced by genetics and breeding. Specific genetic features and breeding methods that can contribute to increased pig aggressiveness include:
Genetics
Some pigs are predisposed genetically to be more aggressive than others. Certain pig breeds, such as the Yorkshire or Hampshire, are known to be more aggressive than others. Furthermore, genetic abnormalities impacting the pig’s neurological system or hormone levels can increase aggression.
Breeding
Pigs selectively bred for faster growth rates and larger muscular mass may be more prone to aggression since these qualities are connected with increased energy levels, which can contribute to more active and forceful behavior.
Inbreeding
Pigs resulting from inbreeding or a lack of genetic variation are more likely to acquire certain behavioral disorders, such as aggression.
Improper breeding techniques
Certain breeding procedures, such as breeding just the most aggressive pigs, can help to perpetuate aggressive tendencies in the population.
Handling and management practices
Specific practices that can contribute to greater pig aggressiveness include:
Rough handling
Pigs who are handled or restrained violently may become more aggressive if they feel intimidated or disturbed. Hitting, kicking, or employing excessive force are examples of such activities.
Lack of Training and Socialization
Pigs that have not been properly trained or socialized may be more prone to aggression since they are less accustomed to human interaction and may feel threatened by unfamiliar persons or settings.
Unstable Routine
Pigs that do not have a stable routine or are subjected to abrupt changes in their surroundings may become anxious and aggressive.
Inadequate nutrition and care
Pigs who do not receive adequate nutrition and care may become aggressive as they compete for resources and become agitated.
Lack of Veterinary Care
Pigs that do not receive regular veterinarian treatment may become aggressive if they feel uncomfortable or in pain due to untreated health concerns.
Lack of Proper Shelter
Pigs that do not have adequate cover or protection from the weather may become anxious and aggressive because they cannot regulate their body temperature or shield themselves from the sun and rain.
Lack of Enrichment
Pigs not given sufficient environmental enrichment, such as straw, toys, or other stuff to root through, may become frustrated and violent.
Signs of aggression in pigs
Pigs can display a wide range of aggressive behaviors, both physical and behavioral. Pigs commonly exhibit the following symptoms of aggression:
Physical indicators
Aggressive pigs may charge at other pigs or humans, bite, or attack with their tusks. As an indication of aggressiveness, they may raise their hackles (back hair) and expose their teeth.
Vocalizations
When pigs are aggressive, they may squeal, growl, or make other vocalizations. These vocalizations may be more powerful and louder than regular vocalizations.
Body Language
They can raise their tail, lower their head, and charge or chase other pigs or humans. They may also indicate their hostile intentions through their ears, eyes, and head position.
Aggression toward other animals
Pigs may be aggressive toward other animals, such as other pigs or other species maintained with them, such as chickens or sheep.
Human aggression:
Pigs can be aggressive toward humans, especially if they feel threatened or anxious. This can include charging or biting individuals and using angry body language.
Not all aggressive behavior in pigs is destructive or hazardous, and some aggressive conduct might be a normal and natural element of the pig’s social activity. Aggressive conduct must be handled and managed appropriately if it becomes excessive or harmful.
Managing aggression in pigs
Aggression management in pigs is critical for their well-being and the safety of those who work with them. The following are some aggression management tactics.
Providing appropriate room and resources
Pigs with adequate space and resources are less likely to become hostile. This can involve giving pigs sufficient space to roam freely and express natural behaviors. It’s also important to provide pigs with enough food, water, and other resources to suit their needs.
Proper Handling and Training
Pigs treated gently and educated to respond to commands are less likely to become hostile. This can entail teaching pigs to answer to orders like “sit,” “stay,” and “come,” as well as rewarding good behavior.
Identifying and dealing with aggressive pigs
Aggressive pigs should be identified and managed separately from the rest of the herd. This can involve giving them more space or providing extra attention and training to help them overcome their violent behavior.
Environmental enrichment
Pigs who are given environmental enrichment, such as straw, toys, or other rooting materials, are less prone to become hostile. This can also assist in alleviating stress and improve the pigs’ overall well-being.
Proper diet and veterinary care
Pigs who are well-fed and cared for are less prone to become violent. This can involve feeding well-balanced food and scheduling frequent veterinary check-ups to address any health issues related to aggressive behavior.
Summary – How aggressive are pigs
- Pigs are generally calm creatures that avoid conflict wherever feasible; nevertheless, some environmental and managerial conditions might increase their aggression.
