Do pigs really swim? Uncovering the swimming ability of pigs
Pigs are ancient omnivorous mammals, divided into domestic pigs and wild boars. Their physical features vary depending on the breed, but they usually have large ears, a long head, a straight snout and a narrow waist and back as their main body characteristics, with fairly coarse and stiff hair, and depending on the breed they come in white, pink, black, brown and spotted colors. Now let us take a look together at whether pigs really can swim!
Do pigs really swim?
Not only can pigs swim, they swim very well. In fact, pigs are not as clumsy as people imagine; they are fairly intelligent omnivores and, after training, can master many skills just like dogs. A pig's ability to swim is an animal's instinct for survival, and they are born knowing how to swim, especially piglets, though pigs that are too heavy may not necessarily be able to swim. At the same time, the average density of a pig's body is 0.975, which means that from a theoretical analysis a pig can definitely swim.
How long do pigs live?
The average lifespan of a domestic pig is 20 years, a pet pig's lifespan is around 10 years, and a wild boar can live 50 years. Pet pigs are omnivores with a modest appetite, and they also like to eat a little fruit and vegetables, such as watermelon and tomatoes; if the owner takes careful care of them, 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 usually culled after 5 to 7 litters (some are culled after 3 litters when their production performance declines), so in large-scale farming they are generally culled after 2 to 3 years.
How intelligent are pigs?
People usually think pigs are a lowly and stupid animal, only suitable for being raised to supply humans with food, but the latest research by scientists shows that pigs are not low in intelligence at all; they are as smart as dogs and can even solve complex problems like chimpanzees. The 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 tasks of locating and finding objects, can understand some simple sign language, and can master complex symbols and signs involving actions and objects.
