The National Animal Identification System (NAIS) is a national program intended to identify animals and track them as they come into contact with, or commingle with, animals other than herdmates from their premises of origin.
The system is being developed for all animals that will benefit from rapid tracebacks in the event of a disease concern. Currently, working groups comprised of industry and government representatives are developing plans for cattle, swine, sheep, goats, horses, poultry, bison, deer, elk, llamas, and alpacas.
