It was an evening in November,
As I very well remember,
I was strolling down the street in drunken pride,
But my knees were all a-flutter,
And I landed in the gutter,
And a pig came up and lay down by my side.

 

Yes, I lay there in the gutter,
Thinking thoughts I could not utter,
When a colleen passing by did softly say:
“You can tell a man who boozes
By the company he chooses.” –
And the pig got up and slowly walked away.

The domestic pig, also called swine, or hog, is descended from the wild boar (Sus scrofa), and most authorities regard it as a subspecies, domestica, of that species, whereas others maintain that it is a separate species, named Sus domestica.

Early domestication
Archaeological evidence suggests that domestication of the wild boar took place as early as around 13000 B.C. in Mesopotamia, with a separate domestication taking place in China about 6000 B.C. As the wild boar has an omnivorous diet, this domestication process was rather easy.

DNA studies indicate that the first domestic pigs were brought to Europe from the Middle East. People soon began domesticating the local European wild boar, causing the genes from the Middle East animals to die out in the European pigs. Later, European animals were brought back to the Middle East, and during the 18th and 19th Centuries, Asian pigs were introduced to Europe. Thus, modern pigs have very complex genes. The majority are more or less pink, with a rather scanty fur.

When Europeans migrated to the Americas, Australia, New Zealand, and elsewhere, they, naturally, brought pigs along. Descendants of these pigs have become feral in many parts of the world, including North and South America, New Zealand, northern Australia, and parts of Europe, often causing considerable damage to the environment.

 

Pig facts
The world population of domestic pigs is around 1 billion, making it as numerous as sheep and goats.

 

In the Indian Subcontinent, most domestic pigs still resemble the wild boar quite a lot, but may have a piebald fur.

Sows are loving mothers, nursing their piglets about every hour. The gestation period is 112-120 days.

Pigs love wallowing in mud, covering their skin with a coating of mud, which protects it from stinging insects.

In many countries around the world, a pig sty is a very simple affair – or simply lacking.

Pig breeds
As with other domestic animals, a huge number of pig breeds have evolved over time.

 

Pot-bellied pigs are a breed, which originated in Vietnam. Today, it is found in many countries in Southeast Asia.

The Andaman pig is only found in the Andaman and Nicobar Islands, a long string of small islands, stretching from Myanmar southwards to the Indonesian island Sumatra. Some scientists regard these pigs as a subspecies, andamanensis, of the wild boar. To me however, it is much more likely that it was introduced by the original Negrito inhabitants of these islands, as it resembles the pot-bellied pig of Southeast Asia far more than it does the wild boar. Some of these introduced pigs probably escaped to form wild populations.

The Linröd pig is an old Swedish breed, which is very rare today, numbering only about 150.

Usage
Pigs are mainly utilized as food, but in earlier days, various items were produced from pig skin, including shields. Tools and weapons were made from the bones, and brushes from the stiff hairs.

In many places in Asia, so-called pig-toilets are still in use in rural areas. It simply consists of an outhouse, built over a pig sty. The faeces fall down into the sty, where the pigs consume them – an eco-friendly and economical way of getting rid of human waste.

A new trend is pigs as pets, usually dwarf forms.

Prior to the invasion of Taiwan by Chinese peoples, the indigenous Malayan tribes of this island roamed the forests, hunting wild boar and other animals. Today, they still love whole roasted pig, but now raise domestic pigs for the purpose.

The population of domestic pigs in Denmark is around 13 million, so it would seem strange, if this animal did not appear on weather vanes.

Clever animal
The pig is a clever animal, and keeping it in small enclosures is a cruel act, which totally disregards the basic needs of pigs, namely to roam about freely and root in the ground with their snout.

The cleverness of the pig was used by English author George Orwell, aka Eric Arthur Blair (1903-1950), who was very much opposed to the totalitarianism, which had just shown its true nature in Germany, and was now being practiced, on the pretext of socialism, by Russian dictator Josef Stalin, who is portrayed in Blair’s novel from 1945, Animal Farm.

In this novel, the animals, led by the clever pigs, usurp the wicked farm owner, Mr. Jones, declaring that “all animals are equal.” Later, “a large, rather fierce-looking Berkshire boar”, named Napoleon, assumes power on the farm and kills his rival Snowball, using dogs he himself has trained. He now declares that “all animals are equal, but some animals are more equal than others,” turning into a replica of Mr. Jones, just much worse. In the end, he even fraternizes with humans, keeping the other animals as slaves. As they peep through the windows, “the creatures outside looked from pig to man, and from man to pig, and from pig to man again; but already it was impossible to say which was which.”

 

 

In Europe, and elsewhere, free-running pigs are a rather recent, but increasing trend, as a growing number of consumers demand products from animals, which have not been kept under cruel conditions.
