Why are pigs pink?

Why are pigs pink?

  1. For one thing not all pigs are pink, some are orange (Tamworths, Oxford Sandy and Blacks), or spotty (Gloucester Old Spots) stripy (Berkshires) and thus not all are pink!
    But most animals’ skin appears pinkish, (unless they have a high concentration of Melanin, which is why some humans have different shades of skin, and why people get a tan). Melanin masks the pinkness which we normally see in some animals, and the pinkness is simply caused by blood flowing in and under the skin.
    But most animals have fur, or hair masking the pink skin underneath, and as most pigs only have a little bristly hair-they often look pink!
