Pigs are also capable of expressing their emotional state

A new study shows that pigs also have the ability to express complex emotional states like humans. Scientists hope through this discovery to arouse people's beloved animal consciousness.

The group of scientists led by Dr. Catherine Douglas of the University of Newcastle (UK) has designed a technology to 'advise' whether pigs are satisfied with their current emotional life or not.

In the experiment (similar to Pavlov's classic reflex experiment), the pigs were trained to recognize two different sounds that were cheerful and optimistic.

The pigs are divided into two groups, the first group is placed in a good environment with ample space, plenty of food and toys; the second group is placed in a small barn and has no toys. Then the scientists made a new sound different from the two sounds that these pigs were trained in. Then proceed to observe their reaction.

Dr. Catherine Douglas said: 'Pigs who live in a good environment appear optimistic. They treat this new sound as a reward and quickly hope to own it. In contrast, pigs living in tight environments appear pessimistic. They think that this new sound doesn't make sense and as a result, no pigs pay attention. '

For humans, we often observe this state. Imagine a little when you encounter a bad day, a confused mood, a constant failure. Now suddenly your boss asks you to come to his office, what would you think? You will definitely think: 'What did I do wrong after all?' .

We can also use this technique to know if the animals that live in the farm environment are happy or not.

Last year, Dr. Catherine Douglas published his research and demonstrated that the milk production of dairy cows was named by the owner and always called by that name more than the dairy cows. name.
