Yes, I understand what you are saying, but I guess I'm not communicating my point clearly enough.
If breeders rely on these to help guide them towards a particular stallion and it shows a D it's a bit misleading simply because the sample is too small. The absence of Mr. Prospector blood in Europe and the infusion of bloodlines that we do not have here is obviously going to affect the result, but what it does indirectly is make it a harder sell if a horse is imported TO this country.
We are at a point where we could desperately use some new bloodlines but if products like this are incomplete because of a lack of relevant sample data, it's going to produce a result that's inaccurate.
These products are not the be all and end all, but if the data is not complete than perhaps it should stipulate it? |

Im glad to see you're beginning to catch on to E-tricks and Untrue-Tricks, Tappiano.
Why dont you ask about the quality and quantity of the stakes winners studied? |

Tappiano,
I can't speak for eNicks but I have to refute your suggestion that the creation of a "D" rating, in this case Cape Blanco/Awesome Humor, is a bit misleading simply because the sample is too small.
That is just not right.
In the case of Cape Blanco/Awesome Humor, the rating is calculated on the rule of Galileo and his sons with mares by Mr Prospector, his sons and grandsons. There are 178 foals of racing age bred on the cross. 121 of these have started for just 4 SW. Part of the TreuNicks calculation looks at Galileo and his sons with all other broodmare sirelines except Mr Prospector. There are 1,485 foals of racing age in this group, 1052 starters and 99 SW.
You can probably work out that the percentage of SW/Foals and SW/Starters is significantly better for Galileo and his sons with mares not by Mr Prospector line sires. As for the claim that the sample size is too small I would contest that 178 foals of racing age is plenty to prove or disprove a cross. It is a D on TrueNicks because the cross has well and truly underperformed the alternatives. I am also unsure how you could use the term 'incomplete'. It may apply to eNicks who only use stakes winners that they hand collect, but it doesn't apply to TrueNicks who use the complete Jockey Club database - literally millions of records - to make their calculation.
As I said earlier, TrueNicks is a tool to use with other things and certainly doesn't take away from good horsemanship which is essential as paper does not run very fast. We have also always suggested intelligent interpretation of these nicks. Some of them are rated "B" but have a slew of G1 winners, while others rate "A" but have mainly regional stakes winners. You have to make a judgement call, along with all the other things you are considering. We include all stakes winners because for some breeders in this country, especially in regional markets, their goal is to just breed a stakes winner no matter the class and to exclude these would deny those breeders relevant information to make informed decisions.
As for 'desperately' needing some new bloodlines, I am not sure that we are not inbred enough. Inbreeding in this industry has negative connotations for whatever reason and the average breeder seems to think that outcrossing, which provides hybrid vigor but makes elite production in subsequent generations harder to achieve, is good. There is an optimal rate to it all but inbreeding generally fixes advantageous genes.
Barcaldine.....at the suggestion of others, I just typed in "Michael Power" and "Thoroughbreds" into Google. Wow. Your well earned reputation is something to behold. _________________ Byron Rogers

Byron Rogers' assumptions on many counts explains why most professional horsemen snicker at him, Alan Porter, Sid Fernando, Jack Werk and their products:
The assumption that the pedigrees of stakes winners in minor races should help serve as the basis for making decisions by breeders interested in important horses is bogus.
So is the assumption for including "stakes winners'' in minor countries, and in countries where racing conditions---and class---has no relevance in the U.S.
And the assumption that horses which have placed in, but not won, Graded races in the U.S. should be excluded from study.
Let's not forget the assumption that sire line nicks with dams' relations other than their sire lines are inconsequential in deriving the coveted letter grades. It apparently doesnt concern them that of 30 ancestors in each horse's first four generations only two of them are "studied."
And what about their indefensible assumption that---even though their sample sizes of relevant horses is pathetically small---historical pairings will produce the same outcomes in the future? Someone should have told them about BOLD RULER and NASCO.
Of course, the Nicksters' biggest assumption that enough naive horse owners will actually pay (or at least pay attention to) their ill-conceived and misleading conclusions may be the only supportable assumption they make. |

Okay, so let me ask you this one last question. I asked it in another thread but never got an answer.
Hypothetically speaking if I wanted to send my mare, Another G to Posse it's a fantastic match because it says Silver Deputy loves Forty Niner so it gives Kodiak Kowboy as the example. Well, if I do a hypo on KK to Another G it gives the same rating and cites Kodiak Kowboy as the best example of the cross. The application does not factor in TWO crosses of Forty Niner which is present in the second hypo. Now, if there had already been some kind of Nick established when inbreeding 3 x 4 to Forty Niner where would I ever see it? This is where there is, IMHO, a narrow lens because what takes priority, the most stakes winners, the biggest sample?
I could design my own database to do what you all did so I'm not going to knock what you've put together because I know what goes into it, but I guess I don't see as much value in the tool as you all do. |

Tappiano,
What you are proposing to do is one of the more successful ways to breed a stakes winner!
The late Olin Gentry famously said "return to the sire the best blood of his dam". Take a look at the pedigree of a horse named Mentality (by Flying Spur). I bought his dam when I was at Arrowfield and he was the first foal we bred out of her. But you have also raised an interesting point, how many times has Forty Niner been inbred to successfully. You need to go to the Pedigree Analysis system that the Jockey Club offer (you can order it on Equineline). It allows you to enter any horse and see what horses have been inbred to it within 4 generations. R Heat Lightning is a SW Inbred to Forty Niner, just not the same way. _________________ Byron Rogers

| "return to the sire the best blood of his dam" is attributed to Col. E. R. Bradley, not Gentry. He bred BLUE LARKSPUR, among others, using this principle. |

| interesting discussion on the nicks thing but i think there are many sure fire matings that have proven to be spectacular failures and there are a lot of spectacular successes that have been in the mold of big brown pin cushions ----there is an interesting saying in the mining industry that says gold mines are where you find them ---- |

Nonetheless, most contemporary references attribute it to Gentry (1900-1990), Bradley's farm manager. Perhaps we could just refer to it as the 'Idle Hour principle'. |

Actually, and I guess I'm just not communicating it clearly enough is that there is a primary and secondary cross and these applications do not differentiate. The dominant cross in the hypo I gave you is ND x MP NOT ND x MP x FN (x2). The primary cross is what you give the rating at not the secondary. All things aside, the main reason why I would not cross the two is they are physically different and that's not a match I would ever want to do. My mare is going to Artie Schiller. |

the cross of storm cat on daughters of rahy has produced 4 stallions ---two pairs od full brothers who are in turn 3/4 to each other
giants causeway/ freud ------- after market/courageous cat
true nicked each with my mare ----
gc with mr p----A
freud with mr p-----C+
storm cat with carson city ----C
storm cat with carson city-----C
the matching of sire lines is inconsistent and the rating from full brothers A vs C+ probably says the females have a lot to say about the mating potential as i suspect GC has had better mares than FREUD
the FREUD/ GC choice is getting easier ---offspring of 10,000 dollar freud earned 30,242 dollars per starter while 85,000 GC earned 24,493 |

Actually I believe this shows the strength of TrueNicks.
Freud has 98 foals of racing age out of Mr Prospector line mares. He has 6 SW. Freud, bred to all other broodmare sires except Mr Prospector line mares has produced 254 foals and 22 SW. He does better with mares NOT by Mr Prospector line stallions.
Giant's Causeway Has 454 foals of racing ae out of Mr Prospector line mares for 41 stakes winners. Giants Causeway as 1012 foals out of all other broodmare sires for 61 SW. He does really well with Mr P mares.
Freud and Giants Causeway react differently to Mr Prospector line mares, but that is genetics for you. Sadlers wells was dynamite with Mill Reef line mares but his full brother Fairy King was not so it is not like this is unusual. The important thing is that it needs to be acurately represented which it is with TrueNicks. _________________ Byron Rogers

MR ROGERS
i beg to differ ---i think it actually shows the major fault with stallion to stallion nicks ---they completely ignore 50% of the gene pool presented to a sire line ----they give no weight whatever to the female families ---of course to get to that influence one would have to drill a little deeper and find out what if any are the common characterisics in the female families in the stakes winners ----what elements are present in the winners and whats missing from the non stakes winners ------zenyatta --- pretty good horse has a great many lines(from the three streams under the stallion pedigree) leading back to pocahontas in what i call direct line----- female -female-female etc or female- male -female ----no female male -male which of course is a stop sign for some gene transmission ----i would even take it one step further and say female families have affinities ---for example 6e / 4m mix ----more study is needed in this area. |

That is fair enough. Nicks represent what they are, genetic affinities between sirelines. It does, as you point out, not consider the bottom 25% of the pedigree but it was never said to and as it stands does hold up to statistical scrutiny. Not much else does in the pedigree theory world.

I agree, but it is a little more complex. Putting on my Performance Genetics hat, what you seem to be talking about there is mitochondrial biogenesis.
The limited coding capacity of mtDNA necessitates that nuclear genes make a major contribution to mitochondrial metabolic systems and molecular architecture. Consequently the vast majority of the mitochondrial proteins are nuclear-encoded and mitochondrial function depends on the coordinated expression of both nuclear and mitochondrial genomes. We are still working on this concept but it seems that in athletic racehorses mitochondrial families have differing nuclear genetic requirements in order to maximize the mitochondrial process. That is, the ‘handshake’ that occurs between the nuclear encoded genes and the mitochondria is reliant upon specific variants within both the mitochondrial and nuclear genes to optimize this process. If you get a lot of horses from the same female family (and identifying them as such is a task itself as while the d-loop region generally places them in families, it is apparently that even within that, selection pressures have come to bear on the 13 protein-coding mtDNA genes), and arrange them into elite and non elite, it is apparent that there are variants within the PPARGC1A-NRF-TFAM pathway that are found in the elite horses, that do not appear in the non-elite. It is complex because the nuclear genes are subject to mendelian inheritance and we are talking about multiple genes at work so it is rolling the dice, numbers of times. We are a fair way away from working it out but it is really interesting stuff.
Dr. Steve Harrison, from Thoroughbred Genetics, has done just about as much work as anyone on mtDNA and at the Pedigree & Genetics conference this year he mentioned what we had already started on above as a possibility along with the possibility that the relative mtDNA groups that the sire and dam belong to have an influence on mtDNA copy number (basically what you are talking about - when you combine a sire from one mtDNA family with a mare from another mtDNA family). _________________ Byron Rogers

Did anyone else catch the new E-Nicks ad promoting it's $595 "enrollment fee" for stallions?
To be eligible for an E-Nicks recommendation a stallion must be enrolled. For mare owners this means that the only stallions that E-nicks will recommend are the ones whose owners paid to play.
So, even though 'better nicking' stallions may be available for a breeder's mare, they will not be promoted by the Werk Company.
To my knowledge, all of the Nicksters operate their businesses in the same manner. |
