At the beginning of the year the owner of every active registered Oldenburger mare will get a so-called “Deckschein” with a duplicate copy. Here the basic data of the mare as well as the address of the owner is included.

Before the covering the “Deckschein” must be handed over to the owner of the stallion.
The covering/insemination of a registered mare without prior handing-over of the “Deckschein” to the owner of the stallion/insemination station is not permitted.

In exceptional cases the presentation of the breeding confirmation (copy) for the identification of the mare is allowed.

The “Deckschein” must include at least the following details:

- Name and registration number of the mare
- Name and registration number of the stallion
- All information regarding the covering
- The registered number of the covering
- Name and address of the owner of the mare
- Signature of the owner of the stallion or his representative.

After the covering/insemination the owner of the stallion (respectively his representative) will completely fill out und sign the “Deckschein”.

The owner of the covered mare gets a copy of the “Deckschein” und has to keep this until the mare gets the foal. When selling the mare the buyer must take over this obligation.

The owner of the stallion collects the first page of the “Deckschein” and sends is to the administrative office of the Verband at latest 30.09. of the year.
