History of pigs

Discover the life of one of the most iconic creatures on the planet, from piglets to sows to sounders. Pigs belong to the Suidae family, which consists of eight genera and sixteen species.


According to research published in the journal Proceedings of the National Academy of Sciences, pigs have domesticated approximately 10,500 years ago in the Near East, before farmers introduced them to Europe around 8,500 years ago.


According to the Encyclopedia of Life, domestic pigs originated mostly from the wild boar (Sus scrofa) and the Sulawesi warty pig (Sus celebensis), separating from their nearest forebears some 500,000 years ago. According to Statista, there are currently 752 million domestic pigs around the globe, with 406 million of them in China.




Pigs are omnivorous animals. They have two functioning and two nonfunctional fingers on their hooves. Wild pigs are not native to North America but are thought to have arrived on Christopher Columbus.


Wild pigs, on the other hand, come in a wide range of sizes and weights. The huge forest hog is the biggest pig (Hylochoerus meinertzhageni). According to the Encyclopedia of Life, it is native to more than a dozen African countries and may grow up to 6.6 feet (2 meters) long and 3.6 feet (1.1 meters) tall.


The biggest boar is the Eurasian wild pig (Sus scrofa), which may weigh up to 710 pounds (320 kilograms), while the smallest is the pygmy hog (Sus salvation). This tiny swine develops to a height of 9.8 inches (25 cm) from hoof to shoulder and a length of 1.8 to 2.4 feet (55 to 71 centimeters). According to the San Diego Zoo, the pygmy hog weighs only 14.5 to 21 lbs. (6.6 to 9.7 kg).




According to the Encyclopedia of Life, pigs, boars, and hogs may be found all over the planet, with the exception of Antarctica, northern Africa, and far northern Eurasia. Wild swine have adapted to a wide range of temperatures and environments. Red river hogs and babirusas inhabit rainforests,bush pigs and forest hogs inhabit woodlands, and warthogs inhabit savannas. Mud wallows are used by anyone to cool off and protect their skin from parasites and bug bites. They are mostly crepuscular or nocturnal, spending the day in tunnels or hollows they dig in thick grass or leaf litter.


Wild pigs are most commonly found in grasslands, marshes, rainforests, savannas, scrublands, and temperate forests. Pigs swim in the mud because it helps them to maintain their body temperature and prevents parasites.




Pigs, boars, and hogs are omnivores that consume almost everything. Small reptiles, animals, and carrion, as well as grasses, water plants, and fruit, make up their diversified diet. Foraging takes up a significant portion of each day. That rough snout is used by all pigs to root in the dirt for food items such as leaves, roots, bulbs, insects, and earthworms. Swine have a keen sense of smell and may detect an edible root or tuber 10 inches (25 cm) below the earth. Wild swine has grown notorious for digging through and ruining substantial amounts of farms; crops as a result of this habit.


Domestic pigs and hogs are given a maize, wheat, soy, or barley-based diet. Pigs are frequently given vegetable peels, fruit rinds, and other leftover food items.


According to the Encyclopedia of Life, most species of pigs absorb plants in their hindguts; nevertheless, their digestion of cellulose is poor, forcing them to eat often.




During the mating season, a boar will follow a sow and frequently poke her to test whether she is receptive. If she is, she informs him by allowing him to smell and taste her pee. He then spends many days with her before going on to locate another sow to mate with, fighting off rival boars with his tusks.

Wild pigs mate throughout the winter when lonely males look for a partner. Once pregnant, wild sows will give birth to around 10 piglets and will share responsibility for rearing them until they reach the age of one year. According to the Woodland Trust, the sounder will thereafter return to his lonely lifestyle.


Domestic pigs may reproduce all year without regard to the seasons. According to the animal rights organization Compassion in World Farming, female pigs, often known as sows, carry a litter of roughly 10 piglets for around 114 days before giving birth.

When the pregnant sow is ready to give birth, she seeks out a secluded location and constructs a nest by excavating a shallow hole and filling it with plant material. A litter of wild pigs can have up to six young (piglets), although certain species can have up to fourteen. Piglets are born with their eyes open and resemble brown-striped watermelons with legs; babirusa, warthog, and forest hog piglets are solid colored.


Piglets spend their first ten days buried in a grass nest dug by their mother before venturing out. Sows and piglets travel as a group until the young are weaned at around three months of age. When the piglets are mature enough, they can join the sounder, which also includes other sows, piglets, and young adults. They stay near to their mother for one to three years until they develop, depending on the species.




Pigs are extremely clever creatures. Wild pigs are usually sociable, living in close-knit groups known as sounders, which consist of adult females (sows) and their progeny, as well as an adult male (boar). Young boars may establish bachelor herds until they reach breeding age. Boars are normally solitary, whereas sows unless they are nursing young, stay with the sounder. Sounders can have several generations.


Sounder home ranges frequently overlap, with common feeding areas, water holes, mud wallows, resting spots, and sleeping caves. Depending on the species, ranges can range from 60 acres (24 hectares) for pygmy hogs to 7 square miles (1,813 hectares) for Eurasian wild pigs.


Pigs have exceptional senses of smell and hearing, and they communicate using a range of grunts, squeaks, and chirrups. Calls are made to stay in contact with the remainder of the group or to warn of impending danger. A quick grunt, a lengthier growl, or a loud roar are all examples of alarm sounds. Pigs also communicate by bodily postures such as lifting the rear crest of hair, cocking the ears, grinding the teeth, or jerking the head up or to the side. Pigs also have smell glands on various parts of their faces. They disperse their fragrance by rubbing their faces against trees or rocks or ramming into the ground.




Humans have hunted bearded pigs for food for about 40,000 years and began domesticating Eurasian wild pigs some 7,000 years ago in Europe, India, China, and Malaysia.


Pygmy hogs are the tiniest wild pigs. They dwell in India, on the slopes of the Himalayas. Little is known about these unusual species, which were considered to be extinct by the 1960s due to poaching and habitat destruction. Then, in 1971, a limited number of miniature pigs were discovered. Pygmy hogs are still in danger of extinction because their habitat is shrinking.


Animals living on a tiny island may find it difficult to flee predators, food shortages, or hunters. This has harmed swine species such as the Visayan warty pig, which is only located on two islands in the Philippines, and the Javan warty pig, which is only found on the Indonesian island of Java.




Large cats, hyenas, and even pythons are natural predators of pigs, while people hunt them for sustenance. The pigs primary defense is speed, although they may be fairly aggressive when cornered. Their bottom tusks are razor sharp and can grow to be roughly 3 inches (7 cm) long, making them great weapons! To avoid leopards, red river pigs can even swim underwater, taking a breath every 15 seconds or so.




Pigs have a lifespan ranging from 5 to 18 years, depending on their domestication state. Wild pigs, for example, live just 4 to 10 years on average due to their habitat and potential predators. Domestic or pet pigs, on the other hand, can live for 20 years or more.

Pigs do not have sweat glands, hence they cannot sweat. Pigs, on the other hand, prefer wallowing in the dirt to cool down.

Pigs will not litter their sleeping or eating places if they are allowed enough room.

Pigs are extremely intelligent animals, and their high degree of intellect routinely puts them one of the world's brightest animals.

Pigs interact with one another via unique grunts and squeals.

Pigs love to be in groups and grow anxious when left alone. They create close ties with each other, as well as with other animals and humans.

The sense of smell is by far the greatest sense in a pig. Pigs use their nose to find food as well as to receive information during social encounters.

Despite their unusual form, pigs can attain speeds of up to 17 kilometers per hour. They are excellent swimmers.

According to scientific investigations, pigs can recall where they may get food and can even distinguish and remember distinct humans and other pigs.

Each pig, like people, has unique behavioral features that define its personality.

Play is an essential aspect of a piglet's social and cognitive development. Even after they reach adulthood.
