View Full Version : interpreting conduit mare profiles?

Mar. 12, 2011, 12:16 AM
I've been searching online, but haven't found anything that explains how to interpret conduit mare profiles. What would the following numbers suggest about a horse?

6-4-4-6-7 Speed = 10 Stamina = 13 Index = 0.83 Triads = 14-14-17

This article may help you a little in understanding the points assignment.
If you understand dosage indexing (Brilliant-Intermediate-Classic-Solid-Professional) related to the stallion's contributions to a pedigree, this is profiling based on influential mares in a pedigree.
Some of the science behind the stats has merit, given that the dam is the exclusive contributor of mitochondrial DNA, the so called energy producing cells (run genes) to a foal.
Here's a link to Steve Roman's site on dosage as well:

I've noticed that the once very active Bill Lathrop has disappeared from sight. He is getting up in years and both his facebook and conduit mare website are no longer available. Bill published both a handicapping and a breeding edition to his system. The breeding edition is very good for both.

As I searched, I came across this 2011 post and thought the discussion might be of interest.

After many years of gathering data, and thousands of hours pouring
over that data, I have come up with what I believe to be a viable
aptitudinal index based on the female family. The data involves the
winners of over 400 Group/Graded races throughout the world run over
the past 40 years (more than 16,0000 individual races). Having
cleared the usage of some of the terminology with Steve Roman (who
has invited me to publish my research on his website), I am pressing
forward. The targets of the index are what I call "Modern Conduit
Mares". These mares are those traced tail female from any individual
which were foaled circa 1900, and not before that date. There is no
criteria used in selecting these mares other than their foaling date.
The basis of the aptitudinal selection is in the racing history of
the runners descending through these "Conduit Mares". I use the same
classifications as the dosage index, B - I - C - S - P, and use a
formula to establish the potential aptitudinal tendencies. So Far,
the conduit mare index has answered some of the questions regarding
the dosage index, such as Kona Gold's stamina oriented numbers in the
dosage index, whereas the Conduit Index clearly establishes him as a
sprinter who would probably come from off the pace. Smarty Jones
conduit index is a perfect balance of speed and stamina, where
Birdstone is more oriented toward stamina, with fewer speed
designations. I am in the process of putting the data together, and
will be having the text edited for a potential book on the subject. I
had a lot of help from Anne Peters, and Tony Morris in gathering
historical information, and from Jessi Pizzuro and Sandy Snider as
sounding boards. I'll keep you posted.

His pedigree intrigues me, and after delving into his lineage, I am
struck by the maternal line influences of the family history. Bruce
Lowe's division of the thoroughbred into female families more than
100 years ago initiated a new tool to use in evaluating pedigree.
His work has evolved through the expansions made by Bobinski and
others into the female families that we know today. Dixie Union is a
case in point where the female family thrusts itself into
prominence. He is line-bred 4x5 to Native Dancer, but the
significance of his pedigree, in my mind, lies in the fact that both
Dixie Union's sire and dam are from Bobinski family #4m.

Interesting. So when are you publishing?

Sorry that was from Bill Lathrops on conduit mare.

The use of quotes would have been nice along with a credit. Well to say the least Bill leaves the industry with a valuable reference. I will say that I recently heard that Bill sold the rights to his publication to someone in Australia. I made inquires but no one has fessed up to the new ownership.

I was aware of some of his collaborations with numerous pedigree analysis, but not with Steve Romans. Actually a review of the Dosage website indicates it may not have occurred or at least been published on Roman's website.

Thanks for clarifying the information. I fear we've lost Bill Lathrop to the ages one way or another. I will sadly miss him as we had numerous exchanges over the years concerning his work.

As Plum Creek noted in another thread, many has dismissed dosage as valuable resource for breeders, handicappers, et al, and I agree but I feel each step we take to analyze the TB and its appitudes is one step forward, not back. After all, particularly when it comes to breeding, the analytical task is more subjective than not.

Thanks again.
