No, I didn't think you did Harmony
I'm so just to defending them that I get kinda carried away, sorry!
Gregoz, they can vary greatly! Ours were bred primarily for meat so we tended to aim for longer, larger types - a lot of herds have smaller pigs, bred down in size.
Ours typically finished at 10-12 months somewhere around the 75kg live weight (50kg dw) size, but I had some from other herds that only made 27kg dead weight at 10 months. Still tasty, just small. Our sows often made 100kg plus and were fab for bacon, gammons and sausages/burgers galore
They're similar meat wise to mangalitzas with the slow growth rate and fat marbling - ideal for charcuterie. You do have to be VERY strict with their feeding, no more than 1lb of pig nuts a day, give them plenty of space and time to grow and you'll be rewarded for your patience
Depending on where you are in the country I might be able to tell you some herds with bigger pigs, or if you contact the breed society they'll have a regional rep who'll be able to help you.
