The possible implementation of voluntary bovine EID as part of European legislation offers significant opportunities to the industry. However, the existing GB cattle numbering system is incompatible with the EID standard (ISO 11784) to be required by Europe. Therefore, there is a significant challenge in finding a cost-effective solution which will not discourage voluntary uptake of bovine EID. This paper details the problems, possible solutions and trade-offs.
