Transcript of PIG
Cultural and religious reference
In Asia the wild boar is one of twelve animal images comprising the Chinese zodiac.
In Europe the boar represents a standard charge in heraldry. Many Abrahamic religions view pigs and those who handle them negatively.
Some religious groups have dietary laws that make pork an "unclean" meat, and adherents sometimes interpret these health issues as validation of their views.

A typical pig has a large head with a
long snout which is strengthened by a special prenasal bone and by a disk of cartilage
at the tip.
The dental formula of adult pigs is 126.96.36.199/188.8.131.52
, giving a total of 44 teeth. The rear teeth are adapted for crushing. In the male the canine teeth form tusks,
which grow continuously and are sharpened
by constantly being ground against each other
The ancestor of the domesticated pig is the wild boar, which is one of the most numerous and widespread large mammals.
Pigs are omnivores, which means that they consume both plants and animals.
Pigs can harbour a range of parasites and diseases that can be transmitted to humans. These include trichinosis, Taenia solium, cysticercosis, and brucellosis.
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 reason pork meat should always be well cooked or cured before eating. Today trichinellosis infections from eating undercooked pork are rare in more technologically developed countries due to refrigeration, health laws, and public awareness.
Pigs also can acquire human influenza.
2. Pigs communicate constantly with one another; more than 20 vocalizations have been identified that pigs use in different situations, from wooing mates to saying, “I’m hungry!”
3. Newborn piglets learn to run to their mothers’ voices and to recognize their own names. Mother pigs sing to their young while nursing.
4. According to Professor Donald Broom of the Cambridge University Veterinary School, “[Pigs] have the cognitive ability to be quite sophisticated. Even more so than dogs and certainly [more so than human] 3-year-olds.”
5. Pigs appear to have a good sense of direction and have found their way home over great distances. Adult pigs can run at speeds of up to 11 miles an hour.
6. Professor Stanley Curtis of Penn State University has found that pigs can play joystick-controlled video games and are “capable of abstract representation.” Dr. Curtis believes that “there is much more going on in terms of thinking and observing by these pigs than we would ever have guessed.”
7. Pigs do not “eat like pigs” or “pig out.” They prefer to eat slowly and savor their food.
8. Suzanne Held, who studies the cognitive abilities of farmed animals at the University of Bristol’s Centre of Behavioural Biology, says that pigs are “really good at remembering where food is located, because in their natural environment food is patchily distributed and it pays to revisit profitable food patches.”
9. Pigs are clean animals. If given sufficient space, they will be careful not to soil the area where they sleep or eat. Pigs don’t “sweat like pigs”; they are actually unable to sweat. They like to bathe in water or mud to keep cool, and they actually prefer water to mud. One woman developed a shower for her pigs, and they learned to turn it on and off by themselves.
10. In his book The Whole Hog, biologist and Johannesburg Zoo director Lyall Watson writes, “I know of no other animals [who] are more consistently curious, more willing to explore new experiences, more ready to meet the world with open mouthed enthusiasm. Pigs, I have discovered, are incurable optimists and get a big kick out of just being.”
