AQHA Board of Directors Votes on Key Rule Changes at Convention

The American Quarter Horse Association Board of Directors voted Tuesday on the recommendations of the AQHA standing committees as approved in the general membership meeting. The following is the final results of the vote regarding hyperkalemic periodic paralysis (HYPP) and the white rule.

The board voted that foals of 2007 and later tracing to the stallion Impressive be required to be parentage verified and, in addition, tested for hyperkalemic periodic paralysis subject to the guidelines in rule 205 (c) (1).

In addition, foals of 2007 and later testing homozygous positive for HYPP (H/H) will not be eligible for registration with AQHA. The board also supported a recommendation made by the AQHA Executive Committee to commence an education and awareness campaign informing the membership of the effects of HYPP.

White Rule
The board voted to delete rule 227 (c) as it applies to the numbered and appendix registries, but to require any horse with white over the current limits to be parentage verified.

The board did amend the stud book and registration committee's original recommendation by adding the following wording as rule 205 (d): "Breeders should be aware that the American Quarter Horse, while long recognized, identified and promoted as a solid-colored horse, can and does occasionally produce offspring with overo paint characteristics. Such markings are uncharacteristic of the breed and are considered to be undesirable traits."

"AQHA is currently working on computer programming and procedures with plans to complete the process by May 1." said AQHA Executive Director of Registration Gary Griffith. "Members can visit for updates and information concerning horses that might be affected by this rule change."
