Never buy sheep or goats from the local auction. It is where most people send their culls. Anything at the local auction can be suspect. I also don't take back anything I have sold since you don't know what the buyer exposed them to. If I guarantee an animal, I will replace it but the one that left the prmises goes to auction.
Sorry about the test results on that ND. Just tell the breeder which ND is positive so she has that information to help her eradicate any other positive animals.
Even with pasturizing and bottle raising the kids, testing once a year is the best and cheapest defense. Although you are not showing, if you send a doe out for breeding she can pick it up. This happened to us. And like you say, until you do the bloodwork yourself any new animal can bring it into the herd, evenfro reputable breeders.I'll probably test at least once a year forever, but we'll probably not have to cull very much once we stop the best defensebringing in does and we get like a year or two behind us. (We're done with that now) Even buying from "clean tested" herds doesn't mean the goats are actually going to test clean. It just means they claim to have a recent all negative test.
