9 C.F.R. § 71.22 Removal and loss of official identification devices.
Title 9 - Animals and Animal Products
Official identification devices are intended to provide permanent identification of livestock and to ensure the ability to find the source of animal disease outbreaks. Removal of these devices is prohibited except at the time of slaughter. If an official identification device is lost, and it is necessary to retag an animal with a new official number, every effort should be made to correlate the new official number with the previous official number of the animal.
