the whole pig id thing is or can be confusing no tag or individual number up to a certain age
pedigree pigs have to be individually identified at weaning with no possible mixing of litters
Scottish executive issue you with a herd number as well
and sheep are just as bad one herd number for ordinary sheep and a totally different one for pedigree
you cant remove a tag as that is illegal and could end up if you followed the rules with an animal that has an ear like a Christmas tree
the bpa herd book number is longer and more straight forward than the kunnie one and can be traced both ways either book number or individual id number
now the cards are reissued to the new owners on becoming members of the bkkps as do the bpa and if the number is the herd book number it should still come back to that pig
86 registered breeders is a far bigger gene pool than some of the bpa breeds Hampshire's have about 13 breeders and are really struggling to get anything past grandsire or dam that is not close related which is why i commented on your opinion initially
and if it is herd book registration numbers it makes interesting readingaround 550 registrations in three and a half years and the next year only 135 with more pigs
