EQS Horse Report
Thoroughbred pedigree analysis reports
A pedigree shows where a horse comes from. The performance data shows whether that family delivers. An EQS horse report puts the two side by side, in one document.

The pedigree itself
The report draws the family tree to the great-grandparents and says how complete it is. In the sample report, 93% of the 14 ancestor places are held, and the one missing ancestor is marked “not in EQS” instead of being left blank or guessed.
From names to numbers: sire and damsire statistics
Names tell you who the ancestors are. The statistics tell you how their progeny have actually performed: the share that ran, the share of runners that won, and the share that secured black type, each set against the database median and shown with the number of progeny behind it.
| Sample report | Progeny | Black type secured | Database median |
|---|---|---|---|
| Shamardal (sire) | 1,285 | 18.8% | 4.9% |
| Dubai Destination (damsire) | 669 | 13.3% | 9.6% |
Both rates sit above their medians. Read what black type means and how the rate is worked out in the methodology.
The cross
The report also looks at progeny of this sire out of mares by this damsire. In the sample there are 9, below the 30-record floor, so the report marks the section partial and says the figures are indicative only. A small sample is shown honestly, not hidden.
The dam's family
The dam's produce record shows her other foals: how many ran and won, their ratings and, where held, their sales. In the sample, the dam has 5 produce on record. The report explains when a shared name means some rows had to be removed.
Reading a pedigree with care
- Look at the number behind every percentage. A rate from 1,000 progeny is steadier than one from 20.
- Compare with the database median, not with zero.
- Check the coverage table before you rely on a section.
- Use the pedigree as a guide to potential. It does not decide what a horse will do.

Questions
- How many generations does the pedigree show?
- Parents, grandparents and great-grandparents: 14 ancestors, which is four generations counting the horse itself.
- What does 93% of ancestor slots held mean?
- It is the share of those 14 places the EQS database can fill with a named horse. A slot it cannot fill is marked "not in EQS", so you can see exactly where the tree has gaps.
- Does a report calculate inbreeding or line-breeding?
- Not at present. A report shows the pedigree and what the sire, damsire and dam's family have produced. To read line-breeding yourself, see the guide on reading a pedigree.
