Pigs: Intelligent and Sociable Farm Animals


Pigs: Intelligent and Sociable Farm Animals

Pigs are among the most versatile and intelligent animals domesticated by humans. With their remarkable adaptability, they have been integrated into a wide range of cultural, economic, and environmental contexts. This article provides an overview, covering their characteristics, domestication history, and significance.


They (Sus scrofa domesticus) are domesticated animals that belong to the family Suidae. Originating from the wild boar (Sus scrofa), they were one of the first animals to be domesticated around 9,000 years ago. Today, they are raised globally for their meat (pork), skins, and by-products, and they also play roles in medical research and as pets.

Amazing Fact

They are highly intelligent animals, often compared to DOGS and chimpanzees in terms of cognitive abilities. They can solve puzzles, navigate mazes, and have been shown to possess a high level of social intelligence, capable of remembering other individuals and forming complex social networks.


They have a compact body, a large head with a long snout that is used for their excellent sense of smell, and small eyes. Their skin is usually covered with coarse hair, which can vary in color depending on the breed. They are known for their voracious appetite and ability to eat a wide range of food, which contributes to their adaptability in various environments.

Domestication and Breeds

Their domestication began in multiple centers around the world, including China, the Near East, and Europe, leading to a diversity of breeds adapted to local conditions. Today, there are over 500 recognized breeds, ranging from the large, pink-skinned varieties commonly seen in commercial farming to smaller, harder breeds used in free-range and organic farming practices.

Pigs Role in Agriculture

They play a significant role in agriculture due to their efficiency in converting feed into body mass, their rapid growth rate, and their ability to thrive on a diverse range of feedstuffs. Pork is one of the most widely consumed meats worldwide, and pig farming is a significant industry in many countries.

Social Behavior

They are highly social animals that form close bonds with each other. They communicate through a variety of vocalizations and body language and even use different grunts and noises to express emotions and intentions. In natural or semi-natural settings, they live in matriarchal societies, with females and their offspring forming the core of social groups.

Intelligence and Training

Their intelligence makes them highly trainable, capable of learning complex tasks and responding to commands. This intelligence, combined with their social nature, also makes them suitable as companion animals, although their size and needs make them a challenging pet for most households.

Difference between Boar and Pigs

  1. Species and Classification:

    • Wild boars are the undomesticated members of the species Sus scrofa.
    • Domestic pigs are the domesticated subspecies, Sus scrofa domesticus, bred by humans for various purposes.
  2. Physical Characteristics:
    • Wild boars have a rugged, bristly coat, longer legs, a more prominent head, and well-developed tusks for foraging and defense.
    • Domestic pigs have been bred to have a variety of coat colors, shorter legs, a more compact body, and generally lack prominent tusks.
  3. Behavior:
    • Wild boars are known for their adaptability but can be more aggressive, especially when threatened. They live in social groups called sounders.
    • Domestic pigs have been bred for docility, making them easier to manage and raise in farming environments.
  4. Diet:

    • Wild boars have a diverse diet, consuming a mix of plants, roots, fruits, and small animals.
    • Domestic pigs are usually fed a diet formulated for rapid growth and health, which can include grains, soy, and vitamins.

Conservation and Ethical Considerations

While domestic pigs are not endangered, their welfare in intensive farming systems has become a significant ethical concern. Issues such as confinement, lack of stimulation, and environmental impact have led to calls for more humane and sustainable farming practices. Additionally, efforts are underway to conserve heritage breeds that possess unique genetic traits and adaptations.


Q: What do they eat?
They are omnivores and can eat a wide range of food, including grains, fruits, vegetables, and occasionally small animals or insects.

Q: How long do they live?
The lifespan of a domestic pig is typically 6 to 10 years, but it can vary depending on the breed and living conditions.

Q: Can they be kept as pets?
A: Yes, they can be kept as pets, particularly smaller breeds like the Vietnamese potbellied pig. However, potential owners should be aware of their needs, size, and local regulations regarding keeping pigs as pets.

Q: Are they clean animals?
Contrary to popular belief, pigs are quite clean. They prefer to keep their living and eating areas separate from where they relieve themselves. Their reputation for dirtiness comes from their habit of wallowing in mud to cool off and protect their skin from parasites and sunburn.

This overview provides a glimpse into the complex and fascinating world of pigs, highlighting their intelligence, social nature, and the multifaceted roles they play in human societies.
