So Much for DOGMA Once Again

OK, this will be the third time I have examined the Rasmussen Factor (RF, inbreeding to females) using sales populations. I am going to use the same excuse for repeating myself as I did for age of mares. “You can never step into the same river twice. . . . ” The sample group is different, and therefore the results could conceivably be different this time around.

Listed below are the 83 stakes winners among sales foals of 2008-2011 who are inbred to females. Listed for each is its name, pedigree (sire–dam), description of the inbreeding, price, and number of Performance Points earned. The stakes winners are listed by years sold, then alphabetically by sire (pretty much the order in which I found them). Discussion resumes at the conclusion of these lists.

The best of these stakes winners were Grace Hall (2,946), Overanalyze (2,046), and Private Zone (1,775).

If these 83 stakes winners came from only 1,000 foals, that would be an excellent result. If these 83 stakes winners came from only 2,000 foals, that would be a good result. The only problem is that these 83 stakes winners came from 2,803 foals, which is not a good result.

Of the total 45,562 sales foals of 2008-2111, 2,803 qualified as RF. That is 6.15%. Incidentally, the last two times I did this study, with sales foals of 1999-2002 and sales foals of 2003-2007, the incidence of RF qualifiers was slightly over 7% in both cases.

In the first two studies the names duplicated most often were Almahmoud and Somethingroyal. Those two names have declined in popularity over time, which is one reason why the overall incidence of RF qualifiers has gone down. It seems to me that the one broodmare who has gained most in popularity over time is Special. I would not be surprised if Special has supplanted both Almahmoud and Somethingroyal as the name most often duplicated.

To review, all 45,562 sales foals of 2008-2111 sold for an average of $46,418 and a maverage of 154. These 2,803 RF qualifiers sold for an average of $51,642 and a maverage of 161.79, higher on both scores. That works out to a Price Index for the 2,803 RF qualifiers of 1.05.

To review, there were 1,426 stakes winners among all 45,562 sales foals of 2008-2111. That is 3.13%. There were 83 stakes winners among the 2,803 RF qualifiers. That is 2.96%. So the RF qualifiers produced a lower ratio of stakes winners from foals than did the overall population.

The 1,426 overall stakes winners averaged 647 Performance Points apiece. The 83 RF stakes winners averaged only 570 Performance Points apiece. So the 83 RF stakes winners were not particularly good stakes winners compared to the overall population of stakes winners.

Taking both quantity and quality into account, the 2,803 RF qualifiers had a PPI (result) of 0.83. That is a pathetic result compared to its Price Index of 1.05. They sold for prices about 5% ABOVE average and produced results about 17% BELOW average.

This result is similar to the previous two results. In all three cases the RF qualifiers sold for prices ABOVE average and produced results BELOW average. The 2008-2011 results are by far the worst of the three.

In coming weeks I will be listing all RF qualifiers sold in 2008-2111. I do so just to assure you that I am NOT making up these numbers. Also so that you may explore more on your own if you feel so inclined. If you want to see how Almahmoud, Somethingroyal, Special, or some other female fared, you can go through the lists and find out on your own. Good luck.

At one point in time no one questioned the Rasmussen Factor at all. It was considered DOGMA that RF produced good results.

That was because no one had ever bothered to TEST large populations for the true efficacy of RF. Once tested, it turns out that the RF is NOT a good prescription for breeding a better horse at all. If anything, quite the opposite.

So much for DOGMA once again.

    Once again you have confirmed the brutal truth, there are no real shortcuts. The northwest passage does not exist! My guess is that almost everyone who reads this blog is intensely interested in trying to breed a better racehorse. That is certainly my goal. However, you keep us all in check. By doing the cold calculations, you help us to avoid paths that lead to nowhere. Let me be the first to say that I wish there were an easier way!!! However, I am grateful for the work you do to help your readers better understand the unfortunate and inconvenient truth. Better to know the hard truth, than to stumble blindly and happily along a path to nowhere.

      Thank you, Ned.

      Northwest Passage is a good analogy. Alchemy is even better. Almost all breeding theories promise to transmute base metals (pedigrees that are mediocre or worse) into gold (graded stakes winners). Of course none of them actually do that. At least not with any consistency.

      Yes, the truth frequently is brutal. That is why it is so UNPOPULAR. Most people would rather believe in fairy tales than deal with the truth.
