I'm a member of the shafter FFA in Califorina and i show pigs and i was amazed to find out that people think pigs are just dirty animals i wrote out some facts to help prove my point that pigs are VERY CLEAN AND SMART animals
Despite their reputation, pigs have many positive attributes including cleanliness, intelligence, and a social nature.
Pigs are indeed clean animals. Yes, they do roll in mud, but only because they can't sweat like people do; the mud (or water) actually keeps them cool. If available, pigs, who are excellent swimmers, prefer water to mud. Pigs also carefully keep their sleeping area clean, and will designate a spot as far from this area as possible for waste. Even piglets only a few hours old will leave the nest to relieve themselves.
Those who know pigs can't help but be charmed by their intelligent, highly social, and sensitive nature. Pigs are actually more intelligent than any breed of dog. Like dogs, piglets learn their names by two to three weeks of age and respond when called. They are also very discriminating eaters, and are particular about their living space. Pigs enjoy novelty and are extremely active and inquisitive.
When free to roam, pigs spend much of their day enthusiastically smelling, nibbling, manipulating objects with their snouts, and rooting ("nosing") about in the soil for tidbits. Rooting is so essential to a pig that some animal scientists say that "a rooting pig is a happy pig." Their powerful but sensitive snout is a highly developed sense organ. A pig's sense of smell is so keen that the animal is trained in France to unearth truffles. Using their snouts as shovels, pigs toss clumps of soil and twigs high into the air, searching for the rare and delicious fungus that grows underground near the roots of oak trees. They are also used by police to help search for drugs.
