Inbreeding and Relatedness Coefficients extended to 10 generations

Monday, February 04, 2019 11:29 AM

This morning you may see that we have extended the computations of the Coefficient of Inbreeding and Coefficient of Relatedness to 10 generations. These coefficients were previously calculated over 8 and 6 generations respectively and were done to that generation previously due to computational restrictions, i.e, the speed of the computers and the frequency of...

The Disappearance of Dosage

Monday, December 10, 2018 9:14 AM

A couple of weeks ago the manager of a TrueNicks enrolled stallion called to tell us that a hypothetical mating had generated Dosage Figures that were all zeroes – zeroes for each category in the Dosage Profile; a Dosage Index of zero; and a Center of Distribution of zero. A check confirmed that this was not an error, and nor was it the result of an obscure pedigree... Read More...

mtDNA and Tregonwell's Natural Barb

Monday, October 20, 2014 1:48 PM

A year or so ago another company that I am associated with, Performance Genetics, did a private study on mitochondrial DNA, the strand of DNA that is maternally inherited in all species and can be used to classify female lineages. We were specifically looking into the #1 family of Tregonwell's Natural Barb which is now that of the likes of Black Caviar, Super... Read More...

How Important is Racing Class of the Dam?

Thursday, June 26, 2014 1:00 PM

As we get ready for the start of the Northern Hemisphere yearling sales series, one of the more pertinent questions that we are often asked at TrueNicks is how important is the racing class of the pedigree at hand in determining the success of a mating. While the TrueNicks rating of a yearling can be the same, the chances of a stakes winner occurring from one... Read More...

Kissing Cousins: Australia and Taghrooda

Sunday, June 08, 2014 10:20 AM

Last week saw the running of the Epsom Oaks (Eng-I) and Derby (Eng-I), two of the longest existing classic races in the world and for many the barometer of the Thoroughbred breed. The Derby was won in devastating fashion by the royally bred Australia. A son of the good racehorse and now leading sire Galileo ( TrueNicks ), Australia is out of Ouija Board, one... Read More...

Return to the Sire the Best Blood of His Dam

Tuesday, October 15, 2013 5:00 PM

The breeding maxim " Return to the sire the best blood of his dam " has been attributed to longtime Darby Dan Farm manager Olin Gentry. Gentry wasn't the first to suggest this breeding theory, indeed there is evidence to suggest that it first came into livestock management via the Bedouins in upgrading Arabian stock centuries ago. The theory is that when mating... Read More...

A Date for Delta: Mating Royal Delta

Friday, September 06, 2013 11:25 AM

It goes without saying that it takes an exceptional individual to win Eclipse Awards in three successive years. Among fillies and mares, the feat has only been achieved twice, by Zenyatta (2008-10) and Azeri (2002-04), although Susan's Girl was champion 3-year-old filly of 1972 and then champion older mare in 1973 and 1975. Looking back to the pre-Eclipse Award... Read More...

Departing Adds to Confidence on War Front/Pulpit Cross

Friday, August 16, 2013 11:20 AM

While there is no doubt that nicks tend to run in sire lines, we've also often found it profitable to consider the dam of a stallion when attempting to predict potential crosses. For example, when Smart Strike ( TrueNicks ) retired to stud, we noted that he was a half brother to champion Dance Smartly, a daughter of Danzig. Since Smart Strike was a Mr. Prospector...

Galileo/Danehill Revisited

Thursday, July 18, 2013 12:45 AM

A little over two years ago, we looked at the cross of Galileo with mares by Danehill . This was fast becoming a European mega nick, having—in the space of three weeks—been represented by Frankel, who had just taken the Two Thousand Guineas (Eng-I) in breathtaking style; Golden Lilac, successful in the French One Thousand Guineas (Fr-I); and Roderic O'Connor...

A Key Ancestor for Encosta de Lago

Monday, June 10, 2013 3:45 PM

While he is now considered an "elder statesman" of the Coolmore Australia stallion roster, there can be no doubt that Encosta de Lago (AUS) ( TrueNicks , SRO ) is one of the premier stallions standing in Australia this year. The son of Fairy King has amassed a sensational record at stud with 6.3% stakes winners to foals and 7.6% stakes winners to runners (up... Read More...

A Classic Case of Coincidence?

Wednesday, May 29, 2013 10:40 AM

The interpretation of Thoroughbred pedigrees is no simple matter. The multi-factorial elements that might be considered include nicks, inbreeding, linebreeding, the positions of ancestors relative to one another, the relationship of the pedigree to the female line, and the class of the individuals involved. Given the volume of the data, and the difficulty of... Read More...

Black Caviar's First Mating: Is Redoute's the Right Choice?

Wednesday, April 17, 2013 5:05 PM

Today brought the news of Black Caviar's retirement from racing. The big question now is which stallion will have the privilege of serving the great mare in her first season at stud? But first, to reflect on Black Caviar's remarkable record, her unbeaten 25-race career included 15 group I victories and spanned six consecutive calendar years. She was the world... Read More...

Monday, March 04, 2013 7:00 PM

15.33%. That's the coefficient of relatedness between Frankel and Chrysanthemum, the first mare scanned in foal to the champion racehorse during his first season at stud. As a point of comparison, first cousins are 12.5% related and half siblings are 25% related. Chrysanthemum, owned by the Coolmore team of Tabor, Magnier, and Smith, won a pair of group III races...

This morning I spoke briefly with Brereton Jones of Airdrie Stud, who alerted me to a homebred filly of his with a very clever name. She is by Airdrie stallion Proud Citizen ( TrueNicks , SRO ) out of the winning Langfuhr ( TrueNicks , SRO ) mare Saramar—the exact same cross as Mr. Jones' Kentucky Oaks (gr. I) winner and champion 3-year-old filly Proud Spell... Read More...

Frankel Highlights Success of Danehill Mares

On a week when much will be written about the great Frankel (Galileo– Kind , by Danehill) as he retires to Juddmonte Farms to serve his first season at stud in 2013, this writer had pause to reflect on the outstanding performance of his broodmare sire, Danehill, who has thus far proved himself a phenomenon as a sire and broodmare sire in two hemispheres—a true...

Kauai Katie: Repeating the Pattern

It's still very early in the season for serious juvenile competition, but there is no doubt that one of the most impressive 2-year-old fillies seen to date is Kauai Katie.
