This latest edition (published May 2008) has been produced by Weatherbys, in conjunction with the RCVS and BEVA, in part as a result of the increased use internationally of microchip transponders to identify horses. Nevertheless, the passport, with its recording of a horse’s colour and markings, remains the essential means of identification for Thoroughbred and Non-Thoroughbred horses and ponies under the implementation Regulation of the EC Directives (Commission Regulation (EC) No. 504/2008 of 6 June 2008 and Council Directives 90/426/EEC and 90/427 EEC.
