Grunting Pigs

These mud covered meddlers scrounge around for morsels of anything edible left on the ground. Their huge hindquarters bounce in the sun as they bump and grind against each other, squealing their pleasure when they find a lost piece of carrot, or grunting annoyance at the lack of squishy mud to roll in beneath the sizzling summer rays. Pigs include the domestic pig, its ancestor the wild boar, and several other wild relatives. Pigs are omnivores and are highly social and intelligent animals. With around 2 billion individuals alive at any time, the domesticated pig is one of the most numerous large mammals on the planet. Long isolated from other pigs on the many islands of Indonesia, Malaysia, and the Philippines, pigs have evolved into many different species, including wild boar, bearded pigs, and warty pigs. Humans have introduced pigs into Australia, North and South America, and numerous islands, either accidentally as escaped domestic pigs which have gone feral, or as wild boar. These have typically adapted well, and are increasing in number and broadening their range outside human control. In the wild, they are foraging animals, primarily eating leaves, grasses, roots, fruits and flowers. In confinement pigs are fed mostly corn and soybean meal with a mixture of vitamins and minerals added to the diet.Domesticated pigs are commonly raised as livestock, but some breeds of pig, such as the Asian pot-bellied pig, are kept as pets.
