Why do pigs have pink skin?
Some domestic pigs look pink because their skin lacks pigment and is covered with very thin, light fur.PigmentationSkin color is determined by cells that contain pigment. Pig skin, like human skin, is colored by the pigment melanin. Skin shade depends on the amount of melanin.Pig ColorCommonly farmed pig breeds have very little pigment and so have pink skin and light or white fur. Like light humans, they can suffer sunburn.Pig FurSkin and fur have similar colors. Pigs with dark fur have dark skin; pigs with white fur have pink skin. Spotted pigs have spotted skin.Wild and Feral PigsWild pigs are brown or black, or red and shaggy. Wild-born domestic pigs are called feral pigs. They revert to the wild condition of being dark and shaggy, even when their parents look like farm pigs.AlbinismAnimals without melanin are called albinos. Albinism is a genetic condition. Many domestic animals are albino. They have pink skin, white fur, and pink or light blue eyes.Color VariationDifferent breeds
