5 panel testing as part of PPE?

[rulex]

I am looking at a QH gelding for sale and unfortunately don’t know much about stock breeds as warmbloods are the breed of choice in my discipline. I’ve noticed some sale ads for stock breeds will state a horse is 5 panel N/N and so did some research on that. Seems like the requirements around 5 panel tests are quite new for the AQHA and currently just extend to stallions?

Is a 5 panel test something you would expect on a gelding for sale? Would you consider buying a horse that didn’t have a 5 panel test done? From my research it looks like it takes several weeks to get the test back. Is this always the case or can it be done as part of the PPE with quicker results?

From my research it looks like some bloodlines are more problematic than others, but again, being pretty out of the QH loop, I don’t know what those bloodlines are. Anyone know what I could look out for? No Impressive or Poco Bueno on this horses’s papers, but are there others I should look out for?

For a gelding it doesn’t matter if he is a carrier, only if he is actively expressing the disease and has symptoms. Out of the conditions on the 5 panel, one is fatal at birth and one shows up early in life.

On the other hand people do sometimes come across PSSM or HYPP in adult horses that start to be symptomatic.

The question for a 5 panel on a gelding would presumably be if the test can tell whether he is likely to express the disease. Being a carrier or having a recessive gene is irrelevant. I don’t know enough about the 5 panel to answer that.

I would absolutely not buy any stock horse (or lookalike) without having a negative test for HYPP and PSSM.

Both of those are heterozygous dominant, meaning if they are positive, they are not just carriers. They are, or will likely become symptomatic. There is no guessing at how likely the horse is to express those diseases. Those 2 diseases are not like Frame, or HERDA, where being heterozygous is perfectly fine without health repercussions.

Ok good to know! This would be less expensive than a 5 panel.

Yes. I would test for HYPP and PSSM. You should be able to get results much faster than the 5 panel. I would not buy the horse unless the HYPP test comes back N/N.

Good to know, thanks!

All Impressive descendants must be tested for HYPP prior to being registered. The results are on the papars.

“In 1996, AQHA designated HYPP a genetic defect and undesirable trait. Two years later, the Association added that all Impressive-descendent foals born after January 1, 1998, were required to be tested for the disease and parentage verified for registration, with the results placed on the registration certificate. Since 2007, any horses tested as H/H are not accepted for registration with AQHA.”
