Misunderstandings about pigs that people have

Eating omnivores, preferring to snuggle into feces, or being able to mate for half an hour are common misconceptions about pigs, animals were purebred humans from 9,000 years ago.

Misunderstandings about common pigs

Referring to pigs (pigs), people often think of animals with pink, dirty skin.They often snuggle into feces to feed and sleep.Male boars can maintain orgasm until half an hour.In fact, most of these prejudices are not correct and they stem from narrow breeding conditions.

Wild boars are omnivores and they are not too careful in eating.90% of their food is plants.Perhaps that is why they have no particular interest in feces.If a home pig occasionally chewed feces, it might be because of the cramped, cramped cage that made it so.

There is a group of wild boars at the Basel Zoo, Switzerland, famous for "clean eating" .People give them pieces of sand with apples.Although they are very hungry, they always take the time to clean the food.

They release these pieces of apple 'to a small river that flows through the area where they live, place the apple pieces in the water, then push them back and forth with the muzzle before eating.' right.

In addition to eating problems, pigs are also known as stinking . Wild boar has a swamp in real mud, but it is to cool the body. Pigs do not have functional sweat glands (so it is impossible to say "sweating profusely like swine") .This physiological feature means that pigs are easily overheated, but the mud water evaporates more slowly than clean water.

"Like any other animal, pigs are always looking for ways to feel comfortable," said Greger Larson, Oxford University, UK. "If they get dirty and feel cool, they will still do it. They may find other ways but it will be difficult because they are often raised in crowded farms."

The mud on the skin also has many other effects.It's like a sunscreen that protects skin from burning or mosquito repellent and many other insects.Cleansing mud into the mud is also a convenient way to remove ticks and many other parasites on the skin.Thus, swamping in the mud helps to clean, not to contaminate the skin.

Pink on pigskin is also a product of human.Domestic pigs and wild pigs are members of an animal family called Suidae.The family includes more than 12 pig species such as warthog, pig (pygmy hog), horned pig (babirusas), giant boar (giant forest hog) and African bushpig.

Genetic evidence shows that wild boars are purified twice, from varieties in Asia and Europe.The ancestors of pigs began to be divided about a million years ago, long before they were about 9,000 years ago from purebred humans.Despite being divided for so long, wild boars in Asia and Europe still retain the same characteristics.

But with a pig, it is not so.In these breeds, the genes that regulate skin color vary, and each type of gene corresponds to the color and pattern on its own skin.According to Larson, this diversity was created over a period of nearly 10,000 years.

"People have refined rare mutations that, if in the natural environment, will be quickly eliminated," Larson and his colleagues wrote in the 2009 report.

The rumored pig is a boar that can maintain orgasm for 30 minutes.The fact is, we don't know how boars, or sows, feel when they commit mating.Therefore, every orgasm statement in this animal is only a guess.

However, when conducting experiments using the method of stimulating the genitals of boars, it was found that the ejaculation time in them was quite long.According to a 2012 study, the average ejaculation time was 6 minutes.The disparity in this time period is quite large among individuals.Some children can ejaculate within 31 minutes.

It is difficult to know if not stimulating them to maintain the ejaculation time so long.Also likely to be there.Practical observations show that mating time between boars and sows usually lasts 4-5 minutes, but sometimes lasts up to 20 minutes.

Whatever the truth about the orgasmic state in pigs, scientists warn pig breeders not to hinder the "fun" of the boars, unless they want to be mad.
