The Pietrain is a breed of pig.
Pietrain, Belgium, the village from which the breed takes its name, was the birthplace of the breed. The exact origin is unknown but the local breed was "brought to the fore" during the difficult period of the swine market in 1950-51. The breed became popular in its native country and was exported to other countries, especially Germany.
The breed is of medium size and is white with black spots. Around the black spots there are characteristic rings of light pigmentation that carries white hair. This, coupled with the fact that the black hair is not as deeply pigmented as on black breeds, or the black spots on some spotted breeds, leaves them with less than the most attractive coats. The breed is commonly referred to as being of piebald markings. The ears are carried erect.
While the Pietrain has recently been loosing popularity in its native country, it does have the potential for providing genetic improvement in carcass quality. In Belgium, the breed is tested regularly for the selection of superior performing lines of swine in the eight test stations that are scattered over the country.
