Using Pedigrees 360 for Our Clients

Lonestar stallions will provide the breeder with a free Pedigrees 360 Report for your mare(s) mated with our stallions. Pedigrees 360 uses artificial intelligence and machine learning to analyze pedigrees and predict the likely success of matings to maximize a mare’s potential.

The Pedigrees 360 software is the brainchild of Leo Tsatsaronis, who was the founder of G1 Goldmine, one of the most widely-used pedigree tools around the world.

“It really is a huge step forward in pedigree analysis and will give elite breeders and yearling buyers an extremely powerful tool in helping predict the likely outcome of a mating,” Tsatsaronis said. “Using AI and machine learning, the program has shown a very high degree of accuracy in predicting which pedigree combinations will produce the champions and which will produce the perennial maidens.”

In designing Pedigrees 360, Tsatsaronis included nine generations of pedigrees for thousands of horses, ranging from elite champions, down to the least successful runners, and tasked the software with finding the qualities that separate them.

While it is important to find the breeding combinations that work, Tsatsaronis noted that it’s just as important to identify which mating patterns are unsuccessful; especially when those patterns involve fashionable pedigrees. Finding those problem patterns can help buyers avoid costly mistakes at auction, and help breeders avoid producing those horses in the first place.

One of the most exciting aspects of Pedigrees 360 is its ability to identify potential quality horses from matings deemed unfashionable by the commercial marketplace.
Knicks Go, North America’s 2021 Horse Of the Year, is an example of what the software can find. Although the horse is the result of a mating involving a low-fee sire, and he sold for a low price at auction, Pedigrees 360 shows the mating had more potential than conventional wisdom might suggest.

The AI modeling analyzed 48 identifiable clusters within nine generations, with clusters being items such as counts of sire duplications, counts of sex-balanced mare duplications at seven, eight, and nine generations, and inbreeding positioning between generations.

It turned out that 40 of the 48 clusters were not significant, but eight clusters showed a clear difference between the “Champions” and the “Slow” sets and those eight clusters form the basis of the cluster chart.

Interestingly, the modeling identified that the eight significant clusters were different for colts and fillies. It is clear there are colt patterns and filly patterns, and that could explain why brothers and sisters often exhibit completely different racing ability.

“Obviously, there are always going to be horses which believe their pedigree,” Tsatsaronis said.

“Some which the program suggest are going to be outstanding are actually slow and vice versa but so far these are proving to be a small percentage and maybe the result of some biomechanical factor rather than pedigree.”

As shown on these two reports, “Knicks Go” and “Curlin”, Pedigrees360 is spot on.

Guidelines for Superior Horses

Guidelines for Champions

  1. ONE single cluster that is ‘off the charts’ as shown by a Green dot that is above the upper range block is present in 70% of Champions.
  2. Champions can have 1 red dot (55%).
  3. It is interesting that 100% of Tesio-bred champions have 3+ Green dots
  4. It is interesting that 100% Tesio-bred champions do not have 2+ red dots
  5. Breeding a horse with 4+ Green quadruples your chances of breeding an elite horse

Identifying Very Slow Horses

  1. 2 or more clusters in the Slow and Very Slow categories ie 54% of Very Slow horses have 2 reds.
  2. 3 or more red dots are in only 23% of Slow horses but in only 8% of Champions so breeding a horse with 3+ Red dots triples your chances of breeding a slow horse
