All mares and stallions which shall be used in Hanoverian breeding must be entered into the Hanoverian mare or stallion studbook.
All the information concerning the horse are noted here (e.g. pedigree, colour, sex, date of birth, inspection score, performance test etc.) The breeding stock must pass through a section procedure before being entered. With regard to the mares this is the studbook inspection. A foal can be registered and branded only of its dam was entered into one of the studbook divisions. This can be carried out even in the year of birth of the foal, i.e. it need not necessarily be carried out in the year of mating.
