karen i have no idea of blood lines tbh we were given 4 kk's last year they were june born and the people that had them were surprised a male and a female would mate as they were pet pigs, she had such a good nature we decided to keep her and have the 3 boys for meat (which we have done), so we brought in a young unregistered boar and hey.
we will be giving her plenty of goats milk to keep her condition up along with a endless supply of fruit and veg, hay, comprey (sp ?), pea straw, grass and a top up of PBP nuts so she should be fine.
i must admit we were surprised by the number she had it was all over very quickly just before feed time, which she soon tucked into.
