Young broodmare sires

published: 14 Jul 2015 in Pedigree analysis

Evaluating broodmare sires is a precarious business at the best of times. Even more challenging is spotting a good one early enough to be able to act on the information.

In truth, I suspect that very few breeders ever make decisions primarily on the sire of a mare, as there are far too many other more important aspects to consider. It is all too easy to be forgiving of an essentially failed stallion in the broodmare sire slot as long as the mare is either talented herself or from a very good family.

  So what makes a good broodmare sire? Observing plenty of Group winners out of his daughters is the obvious starting point. But that alone may not tell the whole story. Sires who have been given the best of mares when they went to stud tend 
to follow through with good broodmare daughters. It doesn’t mean they will become a successful sire of broodmares.

  For this study I have concentrated on broodmare sires born 1990 or afterwards. They must have a minimum of 200 starters to be included in our table that is restricted to racing in Australia and New Zealand. Using ratios of Stakes winners 
as a barometer of success, I have created a comparable index to gauge the quality of opportunity the daughters of each broodmare sire has received. Essentially, if all runners out of a broodmare sire’s daughters are by stallions that produce 8% Stakes winners, then that becomes the broodmare sire’s pass mark. He needs to reach or surpass this mark to be considered a successful broodmare sire. If – as usually is the case – there are a mixture of sires, we average each individually: three runners by 10%, 5% and 3% sires would set the broodmare sire’s comparable index at 6%.

  Four-time Champion sire of New Zealand O’Reilly tops our table of young broodmare sires. The dual G1-winning sprinter/miler by the brilliantly speedy Last Tycoon is currently averaging 7.3% Stakes winners. And although most of the major runners produced by his daughters have done their winning in New Zealand, it is still remarkable that O’Reilly has amassed such a ratio of Stakes winners, given that the sires employed to cover his mares have a combined record of only 4.7% Stakes winners. His recent standout performers include G1 Coolmore Classic winner Steps In Time and we can look forward to many more successful runners employing her Danehill-line/O’Reilly cross.

  Second on our list is Gold Brose, also a New Zealand sire who has demonstrated that he can play a part in the best of international pedigrees. A Silver Slipper winner by the Dewhurst hero Huntingdale, his chief claim to fame so far is the outstanding sprinter Little Bridge who won Royal Ascot’s King’s Stand Stakes in 2012. More recently the Dubawi brothers Tiger Tees, winner of the G1 Galaxy, and G2 scorer Ball Of Musle have been flying the flag in Australia for Gold Brose. 
Both Pins and Redoute’s Choice – third and fourth on the table – are pretty good examples of the ultra young up-and-coming broodmare sires. A G1 winner of the Flemington Guineas, Pins has amassed 14 Stakes winners so far (6.8%) including six G1 horses. The truly great Redoute’s Choice was always going to be an interesting proposition as a broodmare sire. Many of his broodmare daughters will be choicely bred, so much so that – all things being equal – you could be fairly sure they’d help most stallions improve their output. And the evidence is that they certainly do. 

The combined projected ratio of Stakes winners for the sires that have runners out of Redoute’s Choice mares is 4.4%, which is a long way shy of his own incredible score. Nevertheless, the Redoute’s Choice mares have moved that 4.4% score up to 6.6%.

The best of the early runners include the outstanding multiple G1 winner Sacred Falls, plus the most recent winner of the G1 Champagne Pasadena Girl.
Our table features the top 20 broodmare sires by Stakes winners to runners but not all are proving capable to matching their pass mark as laid down by their mares’ covering sires. As many as nine of the 20 have lower scores. n
