Rasmussen Factor

A little over two years ago I did a series on the Rasmussen Factor (inbreeding to females within five generations), using sales foals of 1999-2002. That was so much fun I decided to do it all over again, this time with sales foals of 2003-2007. I think y’all should be familiar enough with the format by now that I will dispense with the explanation of the chart. Discussion starts after the chart ends.

First a note on housekeeping. For sales foals of 1999-2002 I divided Japanese earnings by 8.5 in calculating Performance Points. For sales foals of 2003-2007 I lowered that number to five because I thought the gap between Japanese and other earnings was narrowing, and I wanted to be a little more conservative.

Eishin Lombard is an example. He won one legitimate G3 race in Japan and earned $1,245,148. So he earned 200 Performance Points for the G3 win and 249 points for this earnings for a total of 449. Those earning were from BRIS. I checked the TJC data base and found somewhat higher earnings there. So he is listed in the chart above as having 455 Performance Points.

Racehorse Breeding Theories offers the following definition: “The Rasmussen Factor (RF) occurs when there is a duplication of a female ancestor, between the individual’s sire and dam, within five generations (5×5 or closer).” Not everyone totally agrees with that definition. I will deal with that discussion later.

There are 170 stakes winners listed in the chart above. If those 170 stakes winners were achieved from 4,000 foals, the results would be pretty good. If 4,500 foals, the results would be slightly above average. If 5,000 foals, the results would be below average.

In fact there were 5,110 foals with the RF among these sales foals of 2003-2007. That represents 7.23% of the total of 70,714 foals. That is very close to what it was for sales foals of 1999-2002 (3,886 of 54,244 foals, or 7.16%, over four years).

So the percentage has risen slightly, and the results are below average. I will demonstrate the latter in some detail.

The 5,110 RF foals sold for a gross of $314,777,593, an average of $61,600, and a maverage of 172.93. That is higher than the overall figures for all 70,714 foals (average of $54,140 and maverage of 163.11). So the RF foals sold for higher prices. They should have produced better results. They did not.

Of these 5,110 RF foals, 170 (3.33%) were stakes winners. That is just slightly below the results for the overall group (2,373 stakes winners from 70,714 foals, or 3.36%).

The 2,373 stakes winners in the overall group earned a total of 1,431,157 Performance Points, an average of 603 apiece. The 170 RF stakes winners earned a total of 94,827 Performance Points, an average of 558 apiece (well below the overall average of 603).

This lack of quality among the 170 RF stakes winners can be documented another way. Only one of those 170 RF stakes winners (Round Pond, 3,399) earned 2,000+ Performance Points. That is 0.59% of all 170 stakes winners. Overall, 87 of the 2,387 stakes winners (3.67%) earned 2,000+ Performance Points. Those 170 RF stakes winners should have included four or five (4.6, to be exact) with 2,000+ Performance Points. They actually included only one. That is a big reason their results are below average.

The 70,714 overall foals earned a total of 1,431,157 Performance Points, an average of 20.24 apiece. The 5,110 RF foals earned a total of 94,827 Performance Points, an average of 18.56 apiece. That means the 5,110 RF foals had a PPI (Performance Points Index) of 0.917 (18.56 divided by 20.24), making them about 8.3% BELOW the overall average of 1.00.

I mentioned that the 5,110 RF foals had a maverage of 172.93. That translates into a Price Index of 1.06 (172.93 divided by the overall maverage of 163.11). So the 5,110 RF foals sold for prices about 6% HIGHER than average and produced results about 8.3% BELOW average.

For sales foals of 1999-2002, the corresponding figures were a Price Index of 1.0436 and a PPI of 0.975. So the gap between price and performance has widened from sales foals of 1999-2002 to sales foal of 2003-2007.

I mentioned that not everyone is in total agreement with the definition of RF listed above. Earlier versions included the adjective “superior” in describing the name being duplicated. If we define superior as a mare who was either a stakes winner herself or who produced at least one stakes winner, how would that affect the results???????

Very, very little. Only 69 of the 5,110 foals would be eliminated using that definition of “superior.” Thirty of them would be eliminated because the name duplicated is Mixed Marriage, who is considered a “star” mare (the female equivalent of a chef-de-race, for whatever that is worth). Those 30 actually sold pretty well (average of $76,502 and maverage of 216.93) but produced no stakes winners.

Twenty-one would be eliminated because the name duplicated was Bebop II. Those 21 sold for an average of $35,283 and a maverage of 151.24 and produced one stakes winner, Exotic Bloom (457 Performance Points).

Another 18 would be eliminated because of a variety of names. Those 18 sold poorly (average of $18,982 and maverage of 96.33) and produced no stakes winners. So overall, 69 would be eliminated. Those 69 sold for an average of $48,952, a maverage of 165.48, and produced one stakes winner, Exotic Bloom.

So if you eliminated those 69 foals, the resulting PPI would be 0.925 (up from 0.917), and the resulting Price Index would be 1.061 (up from 1.06). Very little difference.

And who is to say that Mixed Marriage and Bebop II were not “superior” in the first place???? If names of mares of little or no distinction are duplicated, it is because SOMEONE has instructed people that inbreeding to mares is good (period).

At this point I would like to consult the readership on a matter of procedure. I am disinclined to list all 5,110 foals and their pedigrees for two reasons. The first is because I get the impression that the readers are not particularly interested in these big long lists of foals and their pedigrees. The second is because it is a lot of work and not worth doing if no one is gonna peruse the results (though it would be a DIFFERENT story if someone were willing to PAY me to produce a list of all 5,110 nags and their pedigrees).

I have thought about a series of partial lists. For example, I have mentioned that the four most popular names duplicated among sales foals of 2003-2007 are Somethingroyal, Almahmoud, Natalma, and Gold Digger. I could list all the Somethingroyals in one post, all the Almahmouds in another post, etc.

I have already dealt with duplicating mares from the tail-female family of La Troienne. I have done the same for the family of Rough Shod II but have not posted it yet. Or maybe you the readers have other names you would to see examined in more detail. So I am soliciting suggestions and/or feedback as to what you would or would not like to see with regard to the Rasmussen Factor. I have a lot of data available. I am trying to finger out what particular data would interest the most people.
