What is the average lifespan of a pig?
Pigs are ancient omnivorous mammals, divided into domestic pigs and wild boars. It is now generally accepted that the pig is the abbreviated name for the Suidae family. The domestic pig is a subspecies formed after the wild boar was domesticated by humans, with shorter tusks than the wild boar. Generally speaking, it refers to the pig breeds raised by humans mainly for food. As early as the matrilineal clan commune period, people had already begun to raise them. Now let us take a look at what the lifespan of a pig is!
What is the lifespan of a pig?
The average lifespan of a domestic pig is 20 years, the lifespan of a pet pig is around 10 years, and a wild boar can live 50 years. Pet pigs are omnivorous animals with a modest appetite, and they also like to eat a little fruit and vegetables, such as watermelon, tomatoes, etc. If the owner takes care of them carefully, living 10 years is no problem. The average lifespan of a sow can reach 6 to 7 years, but from a practical production standpoint, they are generally culled after 5 to 7 litters (some are culled after 3 litters when production performance declines), so in large-scale farming they are generally culled after 2 to 3 years.
How high is a pig's intelligence?
People usually think that pigs are a low-level and stupid animal, only suitable for being raised to supply humans with food. However, the latest research by scientists shows that pigs are not low in intelligence, being as smart as dogs, and can even solve complex problems like chimpanzees. Researchers compared and analyzed pigs with other animals, and the results showed that pigs have good long-term memory, are good at maze games, and can complete the task of locating and finding objects. They can understand some simple symbolic language and master complex symbols and signs involving actions and objects.
