(24)Equidae living in the Union should be identified by a lifetime identification document that provides a narrative and a diagrammatical description of the equine animal and records the individual marks of that animal for the purpose of identity verification. These marks may be either inherited, such as more than three whorls, chestnuts, colour marks, rare eye pigment defects, specific muscle depressions, but also detail-rich structures of iris or retina, specific genetic markers (DNA profile) or they may be acquired, such as saddle sore depigmentation and scars, including those from castration of stallions, or a brand.
