| Reminder to Breeders | 18 Aug 2026 |
 Any mare covered by a stallion that has not been registered to stand in the 2026 covering season, will not have the covering recorded in the ASB records, or any resulting progeny accepted. To ensure your choice of stallion is eligible to cover this season, check the stallion’s header block on our website (new imported stallions are exempt and will not be displayed as standing until late August due to completing the import DNA process). |
