Can someone explain the domiance of the Darley Arabian line?

[bdw0617]

was just bored and doing some research, most of which I already knew but, how can one line, be that much more dominant n thoroughbreds today than the other 2? The Beverly turk line is almost extinct. And secondly, do you think that this lack of diversity is one of the culprits to why our horses seem to be as brittle as they are?

The Y chromosome in horses, which is the only thing a sire line tracks is almost identical in ALL horses. Doesn't have a lot of genetic information.

As for why there have been at least 3 bottlenecks Eclipse, St Simon and Phalaris all being Darlley Arabian line stallions. Each time a bottleneck happens the male lines loose diversity. However since this is an almost identical Y it doesn't matter all that much. Diversity is maintained by the female side of the family.

Sire lines fail. All American Standardbreds trace in male line to Eclipse, but through a line that did not persist in Thoroughbreds.

Herod's line prospered in the US in the 1800s, but the male line of Lexington eventually failed to continue producing top sires. Marcel Boussac was very successful with Tourbillon in France, but that line has not continued to produce sires. Any line that fails to produce leading sires will fade and fail.

The resurgence of Man O'War's line through In Reality is something of an anomaly, but if that line keeps producing Tiznows, it will prosper.

American thoroughbreds are NOT inherently brittle. They are NOT.

What US-trained, US-raced thoroughbreds ARE is unfit. They are not trained adequately for the stresses of racing a long distance.

Ever wonder why the Euros smoke US-trained horses in the BC turf races, year after year, and stay sound to compete for several years? Especially when those horses are either bred in the US or bred overseas with US-bred/trained/raced parents or grandparents?

Ever wonder why a horse trained in Dubai by Mike De Kock and wins lights out will come to the US and struggle? Or why Japanese horses invade California and embarrass the home team?

The list goes on and on.

Euro, Aussie/NZ, Japanese, and South African trainers get their horses FIT. Horses who are not fit hurt themselves trying....they will fall (Always a Princess), take bad steps (Eight Belles), strain ligaments, lose their balance and injure themselves, or exceed their cardio capacity and bleed. The sireline is irrelevant.

And you can't forgot those that want to beef up their yearlings for sale, sacraficing health and welfare. Their bone density and the two year old in training sales, how they are treated and trained.
To make an ASSUMPTION that a group of animals are brittle is a very dangerous thing to do.

Start clicking on the 5th generation of almost any TB and eventually you will find many Arab stalliosn other than the big three

seriously, i did not know this. so are "the big three" a myth?

yeah i just checked hard spuns pedigree and noticed like at least 7 foundation sires names i have never heard of. off to research i go.

Darcy's Yellow Turk, Place's White Turk, Bald Galloway, etc....There are many more than that. lol. Check out TB Heritage and Bloodlines.net. Great sites.

I think the point is ALL TBs can trac back at least one of he big three; in addition to many other Arab stallions.

I've seen studies that show that the original founding population of the modern TB had only 31 individuals.

Yep..However, those other stallions were usually Barb or Turk in origin, not arabian. In fact, Darley Arabian was suspected to be Muniqui-In other words, a turkish "tainted" strain. No desert tribe would give up truly valuable and "pure" bloodstock. No matter, the English wanted running horses and that's what they ended up getting.

[griff]

If I read you correctly you are saying there are no pure arabians left??

I believe all he present day "arabians" came from Lady and Lord Blunts arabian studs in Egypt and England, plus the studs establish by n most European countries when they found that Arabian stallions onto locl stick produced a superior war horse
