Black Alpine Pig
The former occurrence of red alpine pigs
New map with the confirmed historical distribution according to Prof. Anderegg (Anderegg Felix, 1898: Illustriertes Lehrbuch für die gesamte Schweizerische Alpwirtschaft) and Johann Jakob Steinmüller (Naturgeschichte des gemeinen Schweines und der verschiedenen Racen der Schweiz; Neue Alpina, 1827). It is possible that red Alpine pigs were also widespread in the Leventina and Goms, but there is no written evidence of this.
