Numbering System

 
The Council on Dairy Cattle Breeding initiated the American ID numbering system January 1998. The goal is to establish a unique, lifetime number for each animal for milk recording (DHIA), breed registry, genetic evaluations and, eventually, animal health. The American ID number does not imply that an animal is registered, thus a producer may use this numbering system for all of their calves, even if they have a mixed herd (registered and grade). Producers should not assign more than one American ID number to the same animal.
