63. Tattoo instead of ear tag A flock ID and individual animal number can take the place of an ear tag. A registration tattoo may also take the place of a tattoo if the animal accompanied by its registration paper.
66. If the seller doesn’t provide a tag, tag the animal with another scrapie tag and record the seller’s name and address so you can prove the animal wasn’t born on your farm.
