Is there an advantage to using Auto ID Active-Database over Active-Colony?
Yes, using Active-Database has the advantage that there will not be 2 animals with the same ID even in independent colonies. This will avoid any possible mix ups. However, Mouse colony is designed to detect animals with the same ID within a colony, and when animals are transferred from one colony to the other. In other words, there is little chance of having 2 animals with the same ID in the same colony.
