Mine have only ever had the normal castration, I have had two piglets go wrong when I changed the vet but apart from that they are usually fine.
I dont advertise my piglets, just birth notify them, then I spose people look them up on the BKKPS website under recent notifications.
I think the appeal for them is that although they are slow growing, they require much less feeding.
They do need a good deal of space though so they dont go fat, my pigs have got a good amount of muscle and are nice and lean. And then if kept on nice flat grass they dont root/root as much
My pigs have not rooted since winter 2011, but when people ask if they root I dont say that they wont! its just my ground is hard and flat and grass, they will root up weeds.
When the sows arent feeding piglets they dont get fed, (well between April-October) but they do have 2 acres of grazing and I have a good supply of windfall apples.
They do make very tasty pork and sausages, the bacon is lovely but I have only tasted my friends bacon as of yet, cant wait to make my own

Due to me taking the pigs far (Barton Hill in Hereford) for the boar last time I only just managed to break even
My parents might be moving in the next few months to a house with no land and so I am moving some of my sheep to rented land near my Uni (cirencester) but cannot find anyone who is willing to rent land to 2 pigs (the two sows who I cannot bear to part with)
So my kunekunes might not be around for much longer
