Facts and Myths about Sows and Boars

Sows (female pigs) and boars (male pigs) are fascinating animals with complex behaviors, physical traits, and reproductive roles. They have been integral to agriculture for centuries and play a vital role in the pork industry.

However, many myths and misconceptions about sows and boars are often rooted in outdated practices or misunderstandings about their biology and behavior.

The truth behind these myths can help farmers, researchers, and animal enthusiasts appreciate these animals better and manage them more effectively.

Here, we will explore some common facts and myths about sows and boars to clarify what’s true and what’s merely folklore.

Fact: Sows Are Highly Maternal and Protective of Their Piglets

Sows exhibit strong maternal instincts, especially during the farrowing (birthing) and nursing phases.

They are attentive to their piglets and protect their litter from threats, including other animals or humans.

A sow will often nurse her piglets with dedication, ensuring they get enough colostrum in the first hours after birth, which is crucial for building immunity.

In commercial farming, managing the farrowing environment is essential, as sows can accidentally injure piglets due to their size.

Farrowing crates, for example, help reduce this risk by restricting the sow’s movement while still allowing her to nurse the piglets. In free-range or pasture-based systems, sows have been observed creating nests for their piglets, further highlighting their natural inclination to protect and nurture.

Myth: Boars Are Aggressive by Nature

One common myth is that boars are naturally aggressive animals. While boars can display aggressive behavior, especially during mating seasons or in unfamiliar environments, aggression is not an inherent characteristic of all boars.

Genetics, environment, and handling practices play a significant role in shaping a boar’s temperament. In fact, with proper training, socialization, and handling, boars can be calm and manageable.

Many farmers find boars raised in quiet environments with regular human interaction tend to be less aggressive. Aggressive behavior is often a result of competition, stress, or fear rather than an innate trait. By reducing stressors and understanding triggers, boars can be raised in a way that minimizes aggressive behavior.

Fact: Boars Have a Strong Sense of Smell

Boars are known for their extraordinary sense of smell, which they use to locate food, identify mates, and detect pheromones. This powerful olfactory sense is essential during mating, as boars use it to locate sows in estrus (heat).

They can detect these pheromones from significant distances, which helps them identify fertile females and increases their chances of successful reproduction.

In some regions, wild boars are used for truffle hunting because of their remarkable sense of smell. Truffles produce a compound similar to a pheromone found in sows, which attracts bears. This ability highlights boars’ olfactory capabilities, an evolutionary trait that has helped them survive in the wild.

Myth: Sows Have Low Intelligence

Pigs, including sows, are often mistakenly viewed as unintelligent animals. This myth couldn’t be further from the truth. Pigs are brilliant animals, frequently compared to dogs regarding cognitive abilities.

Research has shown that pigs can solve complex tasks, recognize individuals, and even understand symbolic language. Sows, in particular, demonstrate problem-solving skills and social intelligence, especially when interacting with their piglets or other pigs.

Sows can be trained to respond to commands, navigate mazes, and recognize feeding schedules in farming settings.

Their intelligence makes them adaptable animals, capable of forming social bonds and learning from their environment. This cognitive ability also means they require mental stimulation and an enriched environment to thrive, as they can become bored or stressed in monotonous settings.

Fact: Sows Have a Complex Social Structure

Sows are social animals that establish complex hierarchies within their groups. Sows form social structures based on dominance, influencing their behavior and interactions when housed together.

These hierarchies determine access to resources like food and space. Rather than overt aggression, dominant sows often assert their position through subtle gestures or nudges.

In group housing systems, it’s essential to introduce new sows carefully, as disruptions to the hierarchy can cause stress or fighting.

However, when appropriately managed, sows can coexist peacefully, displaying social behaviors such as grooming, nesting, and vocal communication.

Social structure in sows is a testament to their intelligence and adaptability, allowing them to live in groups while maintaining harmony.

Myth: Boars Are Unhygienic Animals

Another misconception is that boars are dirty or unhygienic animals. In reality, pigs, including boars, are pretty clean by nature. They wallow in mud to regulate their body temperature, as they lack sweat glands, and to protect their skin from parasites and sunburn.

This behavior is often mistaken for uncleanliness, but it is a form of self-care and protection.

In controlled environments, boars prefer to keep their living area clean if they have sufficient space. They designate specific areas for eating, sleeping, and eliminating waste.

Boars and sows both exhibit this preference for a clean environment, so providing adequate space and regular cleaning in enclosures is essential for their welfare.

Fact: Boars and Sows Exhibit Different Reproductive Behaviors

The reproductive roles and behaviors of sows and boars are pretty distinct. Sows experience estrus cycles every 21 days, during which they are receptive to mating.

When a sow is in heat, her behavior changes, becoming more restless and vocal. On the other hand, boars are constantly on the lookout for sows in estrus, driven by their keen sense of smell and instinctual drive to reproduce.

The behaviors associated with mating can sometimes appear aggressive, particularly with boars, who may engage in nudging, sniffing, and vocalizations to communicate with the sow.

These behaviors are natural and play a crucial role in successful mating. Farmers carefully monitor these interactions to ensure both animals are safe and comfortable, facilitating successful breeding.

Myth: Sows and Boars Are Incapable of Showing Emotions

Contrary to popular belief, pigs can express a range of emotions, from joy and excitement to fear and stress. Sows, for instance, show maternal care and comfort their piglets through vocalizations and grooming.

Similarly, boars have been observed to show curiosity, affection, and even playfulness, especially when they are young.

Pigs are emotionally complex animals that form social bonds with humans and other animals. They exhibit behaviors that indicate emotional responses to their environment.

Fact: Sows Are Prone to Health Issues if Not Properly Managed

If they are not properly managed, sows are at risk of developing health issues, especially during pregnancy and lactation.

Common problems include lameness, mastitis (infection of the mammary glands), and reproductive complications. Proper nutrition, veterinary care, and environmental enrichment can prevent many of these problems.

Similarly, boars also face health risks, such as joint and foot problems due to their size and weight. Regular health check-ups, a balanced diet, and well-maintained living conditions are crucial for the overall health of both sows and boars.

Conclusion

Understanding the facts and dispelling myths about sows and boars can lead to better management practices, animal welfare, and productivity in pig farming.

While myths about their aggressiveness, lack of intelligence, and hygiene have persisted, scientific research and practical observation show that sows and boars are intelligent, social, and emotionally complex animals.
