Does Your Horse Have Too Much
The AAHIASM registrations rules states that no more than 25% TB blood is allowed in the AQHA or APHA heritage. This is the #1 reason for elimination of registration. We would like to take this opportunity to explain how to look over the prospective heritage and know for certain the subsequent offspring is eligible for registration, and the AQHA or APHA parent is eligible for American Azteca foundation breeding stock.
Horses with AQHA appendix papers may be eligible. However, and eight generation pedigree, is required to determine the TB blood percentage.
*All pedigree's submitted must be from a legitimate registry such as AQHA or APHA. We cannot accept pedigree from non-official sources such as allbreedpedigree.com or any other non registry pedigree generator.
When viewing your AQHA or APHA pedigree you must have four generations. A generation DOES NOT include the horse's name on the registration papers. The certificate you receive from them only shows a three generation pedigree. You will need to contact AQHA or APHA for an extended pedigree.
Follow the example below. If you have any questions, please contact the AAHIA office, they will be happy to look it over
Example Pedigree of AQHA Horse
1st GENERATION 50%
2nd GENERATION 25%
3rd GENERATION 12.5%
4th GENERATION 6.25%
Sire AQHA Sire AQHA Sire TB = 12.5 % Sire TB = 6.25% Dam TB = 6.25% Dam AQHA Sire AQHA Dam TB = 6.25% Dam AQHA Sire AQHA Sire TB = 6.25% Dam AQHA Dam AQHA Sire TB = 6.25% Dam AQHA Dam AQHA Sire AQHA Sire AQHA Sire AQHA Dam TB = 6.25% Dam AQHA Sire TB = 6.25% Dam AQHA Dam AQHA Sire AQHA Sire AQHA Dam AQHA Dam AQHA Sire AQHA Dam AQHA 0% 0% 12.5 x 1 = 12.5% Total 6.75 x 7 = 43.75 %
THE TOTAL OF THIS AQHA HORSE IS 43.75%
Place the percentage of each TB next to each horse in their prospective column. At the bottom of each column add up the total percentage of TB blood. The generation with the highest percentage would be the total going back to generation four.
