Description and behavior

A pig has a snout for a nose, small eyes, and a small tail, which may be curly, kinked, or straight. It has a thick body and short legs. There are four toes on each foot, with the two large middle toes used for walking.

Pigs are omnivores, which means that they consume both plants and small animals. Pigs will scavenge and have been known to eat any kind of food, including dead insects, worms, tree bark, rotting carcasses, excreta (including their own), garbage, and other pigs. In the wild, they are foraging animals, primarily eating leaves and grasses, roots, fruits and flowers. Occasionally, in captivity, pigs may eat their own young, often if they become severely stressed. This article or section does not adequately cite its references or sources. ... Proper care of the piglets by a mother gilt depends on sanitary conditions and a comfortable environment. ...

A typical pig has a large head with a long snout which is strengthened by a special bone called the prenasal bone and by a disk of cartilage in the tip. The snout is used to dig into the soil to find food and is a very sensitive sense organ. Pigs have a full set of 44 teeth. The canine teeth, called tusks, grow continually and are sharpened by the lowers and uppers rubbing against each other. Cartilage is a type of dense connective tissue. ... Types of teeth Molars are used for grinding up foods Carnassials are used for slicing food. ...

Pigs that are allowed to forage may be watched by swineherds. Because of their foraging abilities and excellent sense of smell, they are used to find truffles in many European countries. Domesticated pigs are commonly raised as livestock by farmers for meat (called pork), as well as for leather. Their bristly hairs are also used for brushes. Some breeds of pigs, such as the Asian pot-bellied pig, are kept as pets. In a draw in a mountainous region, a shepherd guides a flock of about 20 sheep amidst scrub and olive trees. ...

A female pig can become pregnant at around 8-18 months of age. She will then go into heat every 21 days. Male pigs become sexually active at 8-10 months of age.^[2] A litter of piglets typically contains between 6 and 12 piglets.

Pigs do not have functional sweat glands,^[3] so pigs cool themselves using water or mud during hot weather. They also use mud as a form of sunscreen to protect their skin from sunburn. Mud also provides protection against flies and parasites. Sweating (also called perspiration or sometimes transpiration) is the loss of a watery fluid, consisting mainly of sodium chloride and urea in solution, that is secreted by the sweat glands in the skin of mammals. ...

Environmental impacts

Feral pigs in Florida, United States

Domestic pigs that have escaped from farms or were allowed to forage in the wild, and in some cases wild boars which were introduced as prey for hunting, have given rise to large populations of feral pigs in North and South America, Australia, New Zealand, Hawaii and other areas where pigs are not native. Accidental or deliberate releases of pigs into countries or environments where they are an alien species have caused extensive environmental change. Their omnivorous diet, aggressive behaviour and their feeding method of rooting in the ground all combine to severely alter ecosystems unused to pigs. Pigs will even eat small animals and destroy nests of ground nesting birds.^[13] The Invasive Species Specialist Group lists feral pigs as number 90 on the list of the world's 100 worst invasive species and says about them:^[14] Image File history File links Download high resolution version (1084x662, 272 KB) Wild pig - Sus scrofa Source: http://mediaarchive. ...

Health issues

Unlike most other "domestic" animals used as food for humans (cows, sheep, goats, chickens, etc...), pigs harbour a range of parasites and diseases that can be easily transmitted to humans. These include trichinosis, cysticercosis, and brucellosis. Very commonly, pigs are also known to host large concentrations of parasitic ascarid worms in their digestive tract. The presence of these diseases and parasites is one of the main reasons why pork meat should always be well cooked or cured before eating. Religious groups who consider pork unclean may refer to these issues as support for their views. A parasite is an organism that spends a significant portion of its life in or on the living tissue of a host organism and which causes harm to the host without immediately killing it. ... The term disease refers to an abnormal condition of an organism that impairs function. ... Trichinosis, also called trichinellosis, or trichiniasis, is a parasitic disease caused by eating raw or undercooked pork and wild game products infected with the larvae of a species of roundworm Trichinella spiralis, commonly called the trichina worm. ... Cysticercosis is a the most common parasitic infection of the central nervous system worldwide. ... Species Ascaris lumbricoides Ascaris suum Ascaris is a genus of parasitic nematodes. ...

Pigs are extremely susceptible to pneumonia, usually caused by weather. Pigs have small lungs; for this reason, bronchitis or pneumonia can kill a pig quickly.

Pigs can be aggressive and pig-induced injuries are relatively common in areas where pigs are reared or where they form part of the wild or feral fauna.

Domestic pigs are often inbred, leading to the expression of recessive traits. Congenital malformations are common. One such malformation is the duplication of a pig's head.[1]
