Despite the reputation of gluttonous and perpetually dirty creatures (he can find dirt everywhere), pigs are, in fact, very intelligent animals. Whether domestic or wild, pigs are known for their ability to adapt to different environments.

The American zoologist E. Menzel believes that in terms of the development of their own language, pigs are second among animals after monkeys. Pigs respond well to music, for example, they can grunt to the beat of the melody.

Due to their high intelligence, pigs are highly susceptible to stress. Pigs are very attached to their mothers, and if they are separated, especially at an early age, they experience this very painfully: the piglet does not eat well and loses a lot of weight.

The biggest stress for pigs is moving from one place to another. No wonder Academician Pavlov stated that the pig is the most nervous of the animals surrounding a person.

Some scientists argue that the intelligence of a pig is about the same as that of a three-year-old child. In terms of learning ability, pigs are at least at the level of cats and dogs, and often surpass them. Even Charles Darwin believed that pigs were at least as intelligent as dogs.

Various studies have been conducted on intelligence among pigs. In one test, a feeder was connected to a computer. A cursor was displayed on the monitor screen, which could be moved with a joystick. Also, a special area was depicted on the monitor: if you get into it with the cursor, the feeder automatically opens and feed is poured out. Surprisingly, the pigs were perfectly controlled with the Piglet joystick and moved the cursor to the right place! Dogs cannot repeat this experiment and lose here to pigs in intelligence.

Contrary to beliefs, pigs are not at all dirty, but very clean animals. Pigs' love of mud baths is of practical importance, as the mud protects well from overheating and cleanses the skin of parasites. In the end, people are not against therapeutic mud baths.

Pigs have a fantastic sense of smell! It is them, for example, that are used as seekers of truffles - underground mushrooms - in France. Pigs were used to find mines during the war, trained sniffer pigs can easily cope with the search for various drugs.

According to the composition of the blood, the physiology of digestion and some other physiological features, pigs are very close to humans. Closer only monkeys. That is why transplantation often uses donor material taken from pigs. Many organs of pigs are directly or indirectly used in the treatment of dangerous human diseases, and their gastric juice is used in the manufacture of insulin. A pig often suffers from the same diseases as a person, and it can be treated with almost the same drugs in the same doses.
