Cattle Electronic Id Tags - Beef Cattle Product Reviews
The National Animal Identification System covers most livestock species, including cattle, poultry, horses, donkeys, mules, sheep, goats and swine, as well as bison, deer, elk, llamas, alpacas and even some fish species, under the heading of aquaculture.
Household pets such as cats and dogs are not included. The first step in the system is identification of locations, or premises, where these animals are housed or otherwise handled, while identification of the individual animals is the second component. The final part of the program is to track animal movement between the various premises.
The USDA claims the ultimate goal of NAIS is traceback within 48 hours of a diseased animal's movements, which would be possible once the three components of NAIS are fully implemented. This traceback would enable animal health officials to identify all the animals and locations that have had direct contact with the animal and take appropriate measures to prevent the further spread of disease.
