Hi Xisca;
Still many different breeds out there.
Normally I raise a mixed breed. Durok, Hereford, Yorkshire.
Last year we had straight Yorkshire. They are large white ones.
Normally my piggys are a mix of black and white and all white.
I have considered raising the red Tamworth "Bacon" piggys, but they take longer to mature.
Locally folks are now raising mangalica piggys … short hairy piggys known as the kobe
beef of piggys, due to the high fat content. That breed of piggys live outdoors in the snow at below zero (F) … they even have pigglets out in the snow!
