I disagree with Confluence. In my understanding of AFPT this is exactly the point of AFPT--that a high breeding quality horse will have a high AFPT, while a low one is indicative of low breeding ability.

Now, absolutely the mare quality needs to be considered here. So does the number of foals bred and the number of foals tested--without quite a few foals bred and tested you can't really make an assessment.

But if your stallion has a cohort of 25 or more tested foals and you're breeding, as far as you can tell, similar quality horses (for instance, all the mares and the stallion are foundations that passed Breeding Advice), I would take a good hard look at your stallion as the common denominator. If you are breeding a gen 2 stallion to Foundation mares I would be more likely to blame the mares...but I may be wrong to do so!

A link to the stallion in question may help us assess...but if you're only talking about a few tested foals I wouldn't worry. Also I should note that hand breeding instead of breeding to mares with the full pasture bonus will significantly affect PT, so if you're comparing a boy you hand breed/use straws from to a boy you use in a pasture, the hand bred boy will always be at a competitive disadvantage.

I think the point of AFPT as it relates to the breeding quality of the parent is that it indicates which individual parents might have a higher breeding quality range to pass on. Parents who have a comparatively low breeding score for their generation will throw foals whose top possible breeding score is lower than the top possible score of high breeding quality parents--or at least that's how I understand it. So a genuinely low AFPT, when controlled for pasture breeding and mare quality and when the sample size is adequate, would indicate the stallion is of low breeding quality...and doing no favors to your breeding program. This is why I had a minimum AFPT for each generation of my herd and culled by AFPT after every breeding season.

Also about your one really high PT foal upping the AFPT--I'm assuming this is a foundation stallion, who is throwing nothing but foals with a PT of 9.5 and below according to the OP. With the full pasture bonus and both parents being PF equivalent, the highest PT I managed at gen 2 was 10.5. Assuming the stallion has even only 20 or 25 foals with PTs at or below 9.5, it's going to take lots of top end foals to pull that AFPT up...

I would still be really interested in seeing a link to the stallion in question. As Confluence points out, there is no way to tell which individual foals might be the better breeders of his offspring based on their PT, so the only way to figure that part out is to breed them once they're old enough (assuming they have passed whatever testing you have access to).

Here is the stallion in question he's just a regular create. I've PT tested all of the foals that I currently own by him. I think I'll retire him. He's thrown a lot of inconsistent foals. Several of which I've already culled. He throws pretty babies but they are just that and I have plenty of better foundation studs.

Yes I'd snip him to he gave you a lot of foals below his PT score not just a few but mainly all of them

None of the mares were /are tested. I just got the basic upgrade so I'm doing all tests as I have the funds. I'm starting with Gen2 and 3 then will test the foundations last. Thanks for your help. :)
