What kind of saddleback? Are they Essex, Wessex or British? Each one is it's own pedigree and bred together they'd be British, which is a breed of its own as of 1856. So I'd think yes, they'd be pedigree regardless of what they are. If they're both Essex saddlebacks you've got Essex piglets. Same for Wessex and British. And if the sow is one but the boar is another you'd have British piglets.
