Hi Gillian,
As the Tamworth breed rep for Scotland I can confirm that all piglets must be birth notified by 10 weeks of age to be eligable for introduction to the bpa herd book. It is the original breeder that has to birth notify and register the litters. That is if the parents have been registered and you have the registration paper work for them in your name. This is a frequently encountered problem, pedigree parents off spring sold on and the new owners automatically assume that the piglets will be pedigree status. Without the paper work they are just ordinary pigs. As your piglets are 9 weeks old at the moment you still have another week to birth notify them and please remember it can be done online only if you are a registered breeder with the bpa. If you are unclear of any of the above please contact me.
regards,
Lillian
