We offer a Thoroughbred Pedigree Analysis service for Broodmare Mating and Stallion Credentials as well as our  PRI (Pedigree Racing Index) analysis system.

PRI provides an excellent additional tool for relating pedigree to potential racing Ability.…………..

What makes a good race horse?


Galileo: Great Pedigree and Racing Ability

According to the experts there are three factors: Genetics, Environment, and Luck. About 35% of racing ability is inherited according to experts which may explain why horses who have impeccable pedigrees fail to fire on the track. However, unless a horse possess the right genes, the rest won’t matter.  Pedigree and Racing ability can be meshed. A PRI (Pedigree Racing Index) is a new tool which can assist  a pedigree analysis. PRI  comes from linking pedigree and racing ability. Environmental influences include such factors such as nutrition, training methods and the age and sex of the horse.

The role of luck!

Statistically speaking, luck will even out over many runs and a considerable length of time. However, a thoroughbred’s career generally doesn’t stretch that far. About 25 is the  average number of runs in Australia for each horse. Not long enough to remove the bad luck factor. Bad barriers, wet or hard tracks, exceptional opposition, jockeys mistakes can all affect the outcome of the race. The bad luck factor covers all of these.

Of the three factors, genetics is the most important. A poor quality horse is unlikely to win the Oakleigh Plate even if it draws barrier 1 and has Australia’s best jockey aboard. In human terms, a 5’8” man is unlikely to play in the NBA no matter what his ball skills or attitude to training are. The ability conferred by his genetics is not there for the job. Hence it is important to produce the best progeny available from the stallion/mare cross. To do this the breeder has to use all the information he or she can muster . Similarly a purchaser must also understand these matters to ensure their investment is based on the soundest analysis they can make.  

PRI: linking pedigree and racing ability 

The traditional way of assessing a horses chances on the racetrack requires a detailed pedigree analysis. The breeder/purchaser can make employ a number of various breeding theories to measure a horse’s likely ability on the track. We have developed a new addition to improve this analysis which is termed the Pedigree Racing Index (PRI). This measures the link between  pedigree and racing ability. Decisions about the breeding program for a mare will benefit from a PRI score. Similarly, additional information for an existing horse can influence a purchase decision. The PRI  score is  assessed against the horses in our data base. Similarly ,for virtual horses contemplated as part of a breeding program. Contact Dr Bob on  0417540698 for a chat.
