Dogs are actually not as smart as pigs (what you don’t know about pigs)

From childhood to adulthood, the meat we eat most is pork. Pigs are the well-deserved king of meat animals in the hearts of urban and rural residents in my country. Pork is rich in protein, which supports growth and development; pig skin is rich in collagen, which helps skin metabolism; pig bones contain collagen, which makes bones stronger. We can use them to cook bone noodles, stew vermicelli, knead meatballs, make leather shoes, make brushes, etc. If your knowledge of pigs is limited to this, then let me introduce this gentle and lovely guy. In fact, there are still many things you don’t know about it.

Pigs contain a lot of collagen, which can be extracted and converted into gelatin. It is then used as a gelling agent in food and can be used to make gummy candies. In addition to candies, in some beers, wines and fruit juices, pork gelatin is also used to improve the darkness of drinks. It absorbs black substances by reacting with tannic acid in the liquid to clarify.

The fatty acids extracted from pig bone fat can be used to make shampoos and conditioners, which can give hair a pearly luster. These fatty acids are also used in a variety of body creams, foundations, and anti-wrinkle creams. Glycerin, made from pork fat, is also an ingredient in many toothpastes.

What is surprising is that cigarette manufacturers actually use hemoglobin in pig blood in the filters of cigarettes. This ingredient acts as an "artificial lung" in cigarettes and can effectively reduce the toxicity of cigarettes to the human body.

In fact, there is no wasted part of the pig. Pig mouths can be turned into fried dog food, pig ears are used in chemical weapons testing because they resemble human tissue, and pig bone gelatin is also used to help feed black powder or smokeless powder into bullets. Tattoo artists even purchase pig skin to practice their craft, and because pig skin resembles human skin, it is sometimes used on burn victims. Even pig manure has extremely high value. It is currently the fertilizer with the highest quality and largest output in our country, and is the main source of organic fertilizer.

In short, pigs live up to the old saying, "Pigs are full of treasures."

Scientists also discovered that pigs are not inherently dirty. There are not many sweat glands on its skin, so it likes to soak in water to dissipate heat on hot days. Pigs also know how to be hygienic. They always leave the place where they eat and sleep as far as possible to poop and pee. It's just that people keep it in a pigsty so it can't get very dirty.

The general activities of pigs are to explore through the senses such as seeing, hearing, smelling, smelling, gnawing, and gnawing, and through exploration to gain understanding and adaptation to the environment.

Pigs have a well-developed sense of smell and can smell and identify any smell. This is because the pig nose is well developed, the olfactory area is vast, the villi of the olfactory mucosa are large, and the olfactory nerves are densely distributed. Pig babies can identify smells a few hours after birth and use this to find nipples. Within three days, they can fix the nipples and breastfeed without confusion. The sexual relationship between male and female pigs also relies on the sense of smell to conduct communication. Boars can rely on their sense of smell to detect sows in estrus two kilometers away. Sows in estrus can smell the boar's unique sex hormone smell, and can react "stand still" even if the boar is not present. Pigs can rely on their sense of smell to find food buried deep underground, and can accurately find all foreign objects underground. According to measurements, the part of the pig's brain responsible for smell is the same size as the two parts responsible for hearing and vision combined. Therefore, the pig's sense of smell is several times more developed than that of dogs and 7-8 times higher than that of humans. Therefore, through a certain method of training and training, pigs can use their noses to sniff out landmines buried in the soil, and can also be used as customs detection animals, or even as "pig dogs" as guards. It is said that in order to prevent cattle from being bitten by snakes when drinking water by the pond, a farmer raised two pigs to guard the pond instead of humans, and achieved good results. Some people in the United States are raising pigs in farmland, and the number of venomous snakes in the fields has been significantly reduced. It can be seen that pigs can prevent snakes. Scientists have used experiments to prove that there is a scientific reason to raise pigs to prevent snakes because pigs have thick fat that can neutralize snake venom and prevent it from entering the blood vessels.

The hearing of pigs is also quite developed. Pigs have large ears and deep and wide external ear cavities. Even if the sound is very weak, they can be keenly aware of it. In addition, the pig's head can rotate flexibly and can quickly determine the direction of the sound source. Their auditory analyzers are also very complete and can distinguish the intensity, pitch and rhythm of sounds, making it easy to quickly establish conditioned reflexes for various commands and sound stimulation. After training, pigs can dance, play drums, swim, salute, spin in place, open and close cages, push carts upright, and even make sounds similar to human language, and the training time is shorter than that of dogs.

When you mention pigs, what is your first impression? Delicious lazy and stupid pig? Seeing this, you should have realized that pigs are actually much smarter than we think. They are an animal with great wisdom and foolishness. It can be said that among the animals that people usually eat, pigs are undoubtedly the smartest. In many ways, dogs are not as smart as pigs!

Experiments have found that pigs have amazing memory. They can remember different food caches and the size of each cache. If they sniff out that one of their friends knows where food is stored, they will immediately follow that pig. The pig being followed is also very smart. It will find a way to get rid of the follower so that it can enjoy the food alone. Under the soil in some areas of France, a rare black truffle grows. Local farmers use pigs as a valuable helper in harvesting black truffles. Pigs can smell black truffles growing underground at a depth of 25-30 centimeters from a distance of 6 meters. Although dogs can also take on this job, training a dog is much more difficult than training a pig, and the dog must be searched every day. If there is an interval of several days, it will forget. Even if the pig only searches once a week, it will never forget the skills it has learned. Professor Held, from the University of Bristol, said: "Because of their good memory, once they learn something, it is very difficult for them to forget it."

Mirrors are often used to test self-awareness and higher intelligence. Most babies can realize that the person in the mirror is themselves after 18-21 months. Later, it was gradually discovered that orangutans, elephants, dolphins, and several species of birds also had this ability. Now experiments have proven that pigs can also recognize themselves in the mirror, and use the reflection function of the mirror to observe the surrounding environment and find food. Pigs also recognize shapes and can group together pieces of wood of the same shape as well as a three-year-old child. Now some studies have found that pigs have been specially trained to use high technology, can enjoy computer games, and can adjust the heating according to the indoor temperature. They are also the only working animals that can use food self-service machines!

In fact, experiments conducted as early as the 1990s have found evidence that pigs are also very smart. In the experiment, pigs were trained by researchers to use their mouths to move a pointer on a screen and use it to find the graffiti they saw for the first time. The results showed that the time it took them to complete this task was almost the same as that of chimpanzees, which shows how smart they are.

Biologists have discovered that pigs’ metabolism, heart structure, and tooth arrangement are similar to humans. The pig’s vascular system is exactly the same as that of humans and orangutans. Pigs even have many of the same habits as humans. "Pigs like to lie around and will drink if given a drink. They may even smoke and watch television if given the chance," said Professor Schuck of the University of Illinois at Urbana-Champaign.

A pig's life is a happy life. Even if everyone in the world says it is stupid, it doesn't care or complain. It still eats deliciously and sleeps lazily. Cute pig, we all know that you selflessly dedicate all your treasures, how could we know that you still have such a broad mind and smart brain!
