Bisaro pigs are
commonly found in Portugal. They are black to an almost white, pink color and
have a convex dorsal line. They grow to be up to 95cm in height and weight
around 87kg.
They were
classified by J.F. Macedo Pinto in the nineteenth century as Bizaro Type 1, or
Celtic. He believed that they are a variation of Celtic pig from Gaul.
