Although a pig is always associated with an unpleasant odor and dirt, it can easily get rid of all parasites.
Their favorite mud baths contribute to this, so it is a fairly conscious process.
In addition, a layer of dirt protects them from the sun's rays and keeps them cool.
How smart are pigs
It turned out that pigs have excellent long-term memory, skills in arranging objects in space, and can navigate mazes.
They also understand simple symbolic language and can recognize complex combinations of actions.
However, high intelligence has its drawbacks: pigs are more susceptible to stress than other animals.
So, if a piglet is separated from its mother in the early months of life, the piglet stops eating and may even die.
According to researchers, the intelligence of a pig is approximately at the level of a three-year-old child.
Researchers from Germany developed a technique that allowed them to observe how pigs help each other get out of captivity.
How many colors do pigs see
Animals hardly distinguish between blue, green, yellow and red colors; they only perceive white and black with difficulty.
Pigs have good hearing and differentiate its different tones.
