We have both registered, purebred and crossbred, and you takes your money !!
If I registered everything we kept, the BPA would be very rich, and we would be very poor!
The vast majority of our sales are to people who grow for meat, and they do not mind whether the pigs are registered, most buy for quality and to grow for tracibility (knowing where their meat comes from), certainty of care (knowing it has been brought up well), and the outdoor taste (knowing what it has been fed, and that it has been on real ground not concrete).
As stated above crossbred pigs can have hybrid vigour and grow faster, can look very cute (ginger saddlebacks look fantastic, as do extra spotty OSBxGOS's.
From our angle the important thing is that we keep registered lines going, and we do that by selling things that people can afford and want, and that means not restricting ourselves just to registereds.
