I had a buyer ask me the other day, what is the difference in an American Nubian and a Purebred Nubian? Being fairly new to "registered" nubians, I told him the paperwork says "AN" on American Nubians and N on a purebred. What would be the best answer to this question? We have been working with nubians for 2 1/2 years but started with mainly all unregistered stock. Now that we have moved to mostly registered, I have noticed the paperwork has "AN" on some and "N" Thanks for your answers.
