Pig nose structure


Funny pig pig - a legacy of its wild ancestors, who did not have three meals a day. The nose served as an important tool in the extraction of plants, roots, various insects. Food had to be searched for under stones, snags, underground. The scent of pigs is many times better than that of a person. Now many of them even serve, using their snuffing and digging talents. Among them there are good seekers of truffles and explosives.

Nose with a penny and not only ...

The mouth and nose of the pig form the face - the front of the head. The cavity in the nose plays an important role - in it the incoming stream of air is studied for aromas, it becomes warm and moisturized. It is connected through the nostrils with the environment, through the choans (internal openings) - to the throat, along the lacrimal-nasal canal - to the paranasal appendages (sinuses) and the conjunctival sac.

In the structure of the nose there are:

  • root (on the forehead);
  • tip (tip);
  • back (arch);
  • side parts.

The apical part of the pig is mobile, is a proboscis (piglet), which is merged with the lip. There are two holes in it - the nostrils - the "gate" in the nose.

The skin between the nostrils and around is called the nasal mirror. There is no hair on it, but there are grooves dividing it into small lobes with protein glands. They moisturize and cool the piglet's nose.

Subtle Smell of Nature

Bones and cartilages are involved in the formation of the nasal dorsum. It smoothly passes into the side parts, and then into the root, which has a lattice plate at the base (perforated by holes).

The passage inside the nose is relatively narrow, long and slightly widening near the ventral wall. It is divided into the vestibule and the internal cavity with lining its mucous membrane. This shell is smooth, but near the side walls and the root of the nose - in the crease, forming the nasal conchs. They each have 4 nasal passages, which are responsible for smell and respiratory function.

Pigs have the most delicate sense of smell, in its level they can compete with dogs. They are able to smell smells unrecognizable by humans, for example, they can find truffles, various roots, peanuts (peanuts) in the thickness of the earth. Pigs know how to understand herbs.

Truffle hunters

Truffle is considered the most expensive mushroom, its price for 1 kg can reach up to 8000 euros.

Pigs, due to their natural olfactory ability, have always been the first assistants in the search for truffle delicacy.

As a rule, these are specially trained animals, capable of sniffing mushrooms in the cobs under the ground, up to 1 m. The first mentions of truffle pigs are found in ancient Rome.

Now for searches of valuable mushrooms often use not pigs, but dogs. They do not get tired and do not try to eat what they find, unlike pigs. In addition, sows when finding mushroom treasure begin to dig the ground hard, violating the mycelium. After that, it takes a long time to recover - 2-3 years.

Interestingly, the smells of truffles are especially strong at night, therefore, they are hunted at dusk.

Truffle Secrets

The search for truffles should begin at the end of the summer, when they are considered ripe. These mushrooms like to settle on large, open meadows or edges in an oak forest. They grow in large families. It is possible to determine the truffle place by the gray-ash color of the earth, faded grass, moss and tubercles.

In sunny weather, truffle mycelium is given out by yellowing flies swarming above it, which are attracted by the smell of mushrooms. Sometimes you can see the land under the ground - forest animals are trying to find a delicacy.

Truffle young pigs before the hunt wear a pyramid from velvet so that they do not sniff out odors, and a collar. You can pull a muzzle on a piglet, - so he will not be able to eat the mushrooms found. You can distract from this with the help of your favorite treats.

And the scent is like a dog ...

Pigs as holders of fine flair began to be used not only to search for truffles.

"Pigs against terror" was the name of the Israeli project, during which they tried to train them to search for explosives. The idea also lay in the fact that the Islamist suicide bombers consider these animals to be dirty: just their touch can deprive a chance to get to paradise after the terrorist attack.

In the Belgian customs work dwarf pigs. They are looking for not only explosives, but also narcotic substances, prohibited products.

The German customs officer who taught the pig Louise to look for drugs also has this experience. In this, she had no equal among police officers, and for this, for the first time among animals, she received an officer’s rank.

You can learn more about the pig breeds from the articles "Yorkshire Pigs", "Belarusian Pigs Breeds", "Mirgorodsky Pigs".
