Detecting pigs also know empathy as humans

Recent research by Dutch scientists has shown that, besides intelligence, pigs are sympathetic, sharing with their friends.

We know that pigs are a smart animal. Recent research by scientists from the University of Wageningen (Netherlands) has shown that the pigs also know sympathy, empathy, sharing like people.

To draw this conclusion, the researchers conducted 16 groups of pigs, each consisting of 6 notes. They pulled two pigs from each group to train in response to the good or bad things that could happen.

Experts have done this by letting the pigs listen to a few types of music, then rewarding them with food if they have a good performance before each of the expert situations is set or will be punished for taking to the area. next.

Next, two pigs in each group will be "joined" with this newly trained pig. New pigs - called "innocent pigs" will be with you and the barn to enjoy music. A few old pigs who have been trained to listen to the old music have shown happy behavior such as wagging their tails, waving their ears to express happiness. When experiencing some stressful problems, they often urinate and "go heavy".

Although not yet trained, the "innocent pigs" still show their joy to their fellow cousin. Researchers continue to see if these innocent pigs succeed in "spreading emotions" with friends? Over here, experts will see an important aspect of empathy.

They found out, when a pig feels stressed, sad, the "innocent pig" approaches and expresses his sympathy by wagging his tail. This is also shown more clearly when innocent pigs are paired with pigs that are "happy".

Thereby, the experts confirmed that the reaction to the behavior of the pigs proved that he is a sympathetic animal, sharing with his friends.

Previous research has shown that pigs are extremely intelligent, sometimes smarter than dogs. Accordingly, scientists in turn taught pigs characters and simple symbols appear on the screen. After that, they instructed them to use the snout to control the computer mouse to classify characters of the same type.

Some time later, all the pigs in the test program were able to use their snout to categorize maturity, even as fast as the chimp.
