Today we're gonna to learn about pig
Pigs are mammals with stocky bodies, flat snouts that can move independently of their heads,
small eyes and large ears.
They are highly intelligent, social animals,
and are found all over the world, except Antarctica.
Nowadays, there are an estimated two billion pigs on the planet.
China is home to the largest number of pigs of any country.
The European Union and United States are second and third in the list.
Currently there are eight different species of pigs in the world,
include domestic pig and wild boar.
Domestic pig that are well cared for live an average lifespan of 15 to 20 years.
Compared to wild pigs, which are estimated to live only four to eight years.
A sow is a mother pig.
Sows give birth to a litter of young called piglets.
They usually nurse the piglets for three to five weeks.
Newborn piglets learn to respond to their mother's voices,
And mother pigs communicate with their babies through grunts while nursing.
Scientific research has found that piglets have a certain teat order
And each piglet has its own teat to suckle from.
Piglets weigh about 2.5 pounds (1.1 kilograms) at birth,
and usually double their weight in one week.
Fully grown, pigs can grow to between 300 and 700 pounds
(140 to 300 kilograms)
And sometimes much more.
Pigs are smart!
Their intelligence is higher than a dog's,
some primates and even young children of at least 3 years of age.
Like humans, pigs are omnivores.
In the wild, pigs eat everything from leaves, roots and fruit to rodents and small reptiles.
Pigs have poor eyesight, but a great sense of smell.
The pig's nostrils are on its leathery snout, which is very sensitive to touch.
Pigs use snout mainly to dig in the dirt and smell food.
A pig's sense of smell is about 2,000 times more sensitive than human's.
Pigs have four toes on each foot but they only walk on two.
An adult pig can run up to 11 miles per hour.
In their natural state, pigs are very clean animals.
They keep their toilets far from their living or feeding areas.
They are much more tolerant of colder temperatures than heat.
Pigs have no sweat glands so they can't sweat.
This is why they enjoy being in mud to keep themselves cool.
The group of pigs is called a herd.
Pigs snuggle close to one another and prefer to sleep nose to nose.
They dream much as humans do.
In their natural surroundings,
Pigs spend hours playing
sunbathing
and exploring.
Pigs communicate with each other through scent,
body language
and mostly vocal communication.
They have a vocabulary of over 20 distinct:
oinks, grunts, snorts, snarls and squeaks that have specific meanings.
Pigs have excellent memories.
They can remember things for years and can recognize and remember objects.
Pigs are very peaceful animals, rarely showing aggression.
The exception, as with many animals,
is when a mother with her young offspring is provoked or threatened.
Domesticated pigs especially miniature breeds are commonly kept as pets.
They are raised commercially as livestock;
materials that are garnered include their meat (known as pork), leather,
and their bristly hairs which are used to make brushes.
Because of their foraging abilities and excellent sense of smell,
they are used to find truffles in many European countries.
Both wild and feral pigs are commonly hunted.
Human skin is very similar to pig skin,
therefore pig skin has been used in many preclinical studies.
And because of the biological similarities between each other,
pigs can harbour a range of parasites and diseases
that can be transmitted to humans.
