15  FACTS ABOUT PIGS YOU DON’T KNOW

The words pig, hog and swine are all generic terms without regard to gender, size or breed. Pigs originated from Eurasian Wild boars. A pig is any of the animals in the genus Sus, within the Suidae family of even-toed ungulates. Pigs include the domestic pig, its ancestor the wild boar, and several other wild relatives. The domestic pig (Sus scrofa domesticus) is usually given the scientific name Sus scrofa, although some authors call it S. domesticus, reserving S. scrofa for the wild boar. It was domesticated approximately 5,000 to 7,000 years ago. Their coats are coarse and bristly. Their head and body length ranges from 0.9 to 1.8 m and they can weigh between 50 and 350 kg.
