SCANNING through some old racing articles, Mike de Kock came across this one written for ESPN in 2009 by WILLIAM NACK and recommended it for his website. Excellent reading and food for thought…

AS the 20 horses were being loaded into the starting gate for the 2008 Kentucky Derby, with Eight Belles – standing in post position five – poised to make her bid to become only the fourth filly in history to win America’s most important race, Ellen Parker, a thoroughbred breeding consultant and analyst in Kentucky, said quietly to her husband, “I just hope this filly doesn’t break down.”

No, Ellen Parker was not given to eerie premonitions. At 61, she had spent most of her adult life studying and analyzing blood-horse pedigrees; and for years, she’d been consulting clients and arguing vociferously in her newsletter, Pedlines, on the need for thoroughbred breeders to aim for soundness, for durability, as they plotted their matings. She had often sounded, in this equine world driven now by speed, greed and the soulless dictates of the marketplace, like the voice literally crying in the wilderness. What so concerned her on the eve of this Derby, what she found so disturbing, even infuriating, traced to her unshakable belief that Eight Belles was carrying in her DNA the seeds of her own destruction.

Specifically, in the pedigree of this speedy gray filly, Parker had seen the same kind of dangerous crosses – in her case, lines of known unsoundness triply crossed behind an unsound sire line – that she believed had contributed to the racetrack breakdowns and deaths of such prominent horses as Ruffian and Go For Wand, of George Washington and Pine Island, and even of Barbaro. Indeed, when Ellen Parker first perused the bloodlines of Eight Belles, she saw a danger clear and present: a family tree that bore three branches of the extremely brilliant but unsound racehorse Raise a Native, who was a very muscular chestnut, heavy on the front end, who had won all four of his starts before he broke down in front and limped off to stud.

Ruffian, attended to, but later euthanised.

Raise a Native came by his lack of durability quite naturally. He was the fastest son sired by the equally brilliant Native Dancer, racing’s immortal “Gray Ghost,” whose record of 21 victories in 22 starts was spoiled only by a loss to Dark Star in the 1953 Kentucky Derby. By the time Native Dancer had reached age 4, when he started only three times through August, he had gotten so sore due to a chronic inflammation in his ankles – he reportedly had developed osselets, bony growths along his ankle joints – that his owner and breeder, Alfred G. Vanderbilt, was forced to retire him to Sagamore, Vanderbilt’s Maryland farm. There, The Dancer rose to become one of the most successful and influential progenitors in the history of the breed. Through one grandson, the prepotent Northern Dancer, he helped found the most popular and prolific sire line in the world; and through another grandson, the exceptionally fast but unsound Mr. Prospector – yes, a son of Raise a Native – his name gradually appeared at the roots of a far-flung web of sire lines and families that rivalled Northern Dancer’s.

Native Dancer’s sought-after blood started it all.

And herein, ladies and gentlemen of the jury, lies the rub. The thoroughbred breed is now so suffused with the precocious blood of Native Dancer, so filled with his great-grandsons and great-granddaughters, so shot through with distant offspring who carry the markers of his tribe – extraordinary speed with limited durability and soundness – that today it threatens the viability of the entire breed. Of the 20 starters in the 2008 Kentucky Derby, every single one of them carried the blood of Native Dancer. Of course, this line in and of itself is not to be condemned – if, that is, it comes in reasonable doses and is counterbalanced by the blood of sounder strains – but in many of the Derby pedigrees, he appeared multiple times. Native Dancer appeared four times in Eight Belles’ pedigree, most conspicuously in the three crosses of Raise a Native that so troubled Parker when she saw them there.

When Eight Belles shattered both of her ankles as she pulled up past the finish line and galloped out around the clubhouse turn – she obviously broke one ankle first, then snapped the other as she dug it in to support herself – Parker was but one of millions who sat transfixed in horror as the television camera showed the filly lying prostrate on the track.

The recriminations began at once. Columnists, bloggers, talk-show hosts and other observers, some of whom actually know which end of the horse eats, launched into a series of spontaneous public lectures detailing what the problem was and what had to be done. Members of People for the Ethical Treatment of Animals (PETA) picketed the offices of the Kentucky State Sports Authority in Lexington and flooded the organization with e-mails protesting the sport. They unjustly condemned the trainer for running the filly and the jockey for using his whip, however sparingly, the last eighth of a mile.

What Ellen Parker wanted to know, when I spoke to her following the Derby, was why no one was picketing Robert Clay’s Three Chimneys Farm in Midway, Ky., one of the pillars of the Blue Grass breeding establishment and the place where Eight Belles was bred and from where she was sold as a yearling, at Keeneland in 2006, for $375,000.

“They’re the ones who created this tragedy,” Parker said. “Robert Clay is smart enough to know better. He bred her. That’s where it starts. You don’t blame the trainer, who does not have the reputation of breaking horses down, and you don’t blame the poor little jockey. … She was inbred three times to Raise a Native! [She broke down] right where Raise a Native was the weakest, right in the ankles, and everybody acts like they don’t know what caused this filly to break down. It’s written right there for everyone to see! Except they refuse to see it. To admit it is to address the fact that all these stallions that are bred like that, that all the yearlings that are bred like that, are potential accidents waiting to happen. And they’ve got so much money wrapped up in this crap!”

Less than two weeks after conceding to the Wall Street Journal that “there’s a blessing and a curse” involved in breeding descendents of Native Dancer, Three Chimneys’ pedigree advisor, Anne Peters, told ESPN.com, “To blame it on Raise a Native is absurd. Any good mating is a balance of speed and stamina and soundness, and this is a good mating. It is a balance of speed and stamina and soundness. The mating was designed to add soundness through other sources. The fact of the matter is, the filly was sound.”

Barbaro, another unfortunate breakdown.

What is clear right now, in the wake of Eight Belles’ death, is that horse racing has arrived at yet another wrenching moment of crisis and self-examination, one even more critical than the first one I experienced more than 30 years ago. That was on July 6, 1975, when the fastest filly that I ever saw, the undefeated Ruffian – in a nationally televised match race with Foolish Pleasure – pulverized the sesamoids in her right front ankle and had to be destroyed. Like Eight Belles’, Ruffian’s pedigree did not guarantee her demise, but it certainly telegraphed her vulnerabilities to breaking down under the most extreme physical pressures that the sport can offer. Ruffian’s soft-boned sire, Reviewer, had broken a leg three times while in training as a racehorse, and had to be destroyed after breaking down a fourth time in a paddock accident while serving at stud. And, as Parker has pointed out more than once, Ruffian’s dam, Shenanigans, was a daughter of Native Dancer. So she had the same genetic predisposition for unsoundness hanging from the top and bottom branches of her family tree.

“Ruffian was an accident waiting to happen,” Parker lamented.

In 1993, after watching Union City break down in the Preakness and then the Preakness winner, Prairie Bayou, shatter bones in the Belmont three weeks later – both horses were euthanized on the track – I reported and wrote a long investigative story for Sports Illustrated in which I found that, over the past few decades, a sea change had occurred in the breeding of thoroughbred horses, leading to a genetic weakening of the breed, a softening of the horse as a racetrack competitor and the increased use of a variety of drugs, some legal and some not, to keep this weakened, softened animal competitive on the track.

Through the first 60 years of the 20th century, most of the major stallions and many of the best mares were owned and controlled by some of the oldest families and richest sporting patrons in America, by the Whitneys and Woodwards, the Bradleys and Wideners, the Klebergs and Mellons. They bred horses to race them, not to sell them, and they did so in order to compete against one other – to beat their fellow members of The Jockey Club, to see who had the fastest horse. A cardinal article of their faith was to “improve the breed,” which meant to breed a horse with great speed, stamina and soundness. In fact, on the C.V. Whitney farm in Lexington, a foal born with a crooked leg was usually taken into the woods and shot, lest he or she pollute the Whitney bloodlines with this inherent deformity.

By the middle of the last century, this tight-knit racing world began to change. As these families died out and their blue-chip breeding stock was sold at dispersal auctions, the best stallions and mares fell into the hands of commercial breeders, whose central motivation was to breed, not so much a sound or durable horse, but rather an attractive horse, a “cosmetic horse,” who showed well, who had a pedigree filled with fashionable names, preferably sire lines that glowed with speed, and who thus would draw the biggest price at the fanciest yearlings sales. Because they needed to look like show horses, these hothouse yearlings were often raised in small pens and not allowed to run free, or to kick, bite and roughhouse with their peers.

So, not only did the industry begin to breed horses less sound, in general, but also horses that were raised more softly, with kid gloves. John Nerud, the 95-year-old former manager of Tartan Farm, a private stud in Florida, points with pride at all the wonderful racehorses he bred and raised and retired sound, horses like the great Dr. Fager and the sprinter Ta Wee.

“These horses all retired sound because we raised ’em out in the open,” Nerud said. “We did not hothouse ’em or prep ’em for sales. It makes quite a difference when your foal or yearling can run in a pasture. The pounding of those legs strengthens them when they are young and you’ll grow a better bone on a horse.”

What has happened, with the passage of years, is that the thoroughbred is no longer the resilient, hard-boned, robust racehorse that he was in the days when horses were starting 40 or 50 times in a career – back, for instance, when the great 1940s handicap star, Stymie, started 131 times in six years of racing, a physical impossibility for any horse today.

Dr. Larry Bramlage, a prominent equine veterinarian out of Lexington, said that the mid-20th century racehorse was “a bit more angular, narrower-chested, with tendencies toward being knock-kneed, the conformation of human distance runners. Today, if you take the breed as a whole, they are broader chested with tendencies toward being bowlegged and pigeon-toed. Like human sprinters. All fast human sprinters tend toward bowleggedness.”

The horses who are populating the studs these days tend to retire with far fewer starts, their durability and soundness be damned. Nerud would never have bred a mare to such an animal in the past.

“We didn’t breed to unsound, light-boned horses,” he said. “Today, our horses are very delicate, very light-boned. I don’t blame the breeders. They have to breed a cosmetic horse who will show good in the sales ring. But we are breeding ourselves into a hole. We breed light-boned sires that run five or six times to mares who run five or six times. Now what do you expect to get? The resulting foal ends up lucky to run five or six times.”

Indeed, in North America, the average number of yearly starts per runner declined from 11.31 per year in 1960 to 6.37 per year in 2006.

No wonder Bramlage said, “We’re not rewarding longevity like we used to. If we keep going at the rate we’re going, the logical conclusion is that we’ll be down to one start per year for a horse. I don’t think we’ll ever get there, but this ship will have to right its course.”

This gradual softening and weakening of the breed has led to the use of more medications to keep these horses running sound, among them the corticosteroids injected into injured knees and ankles. The cortisone reduces inflammation and allows horses to run pain-free on the damaged limbs or joints, a dangerous practice, if done repeatedly, because it can lead to a more serious injury and to the much-feared catastrophic breakdown. When I started going to races in the 1950s, I hardly ever saw a fatal breakdown on the Chicago dirt tracks; but when I started covering the sport in 1972, in New York, I began seeing numerous breakdowns during a race meet, sometimes two or three a week. One veterinarian told me that this was no accident, that this was the time period when cortisone began to get widespread use on U.S. racetracks, the first signal to me that drugs were a culprit in the sudden increase in catastrophic breakdowns.

“Medication is a symptom,” Parker said. “They need medication because they’re not sound to begin with. Why else would you give it to a horse?”

Drugs are only one way that the industry has been trying to make up for the weakening of the American thoroughbred. A number of racetracks have already replaced their dirt tracks with softer Polytrack surfaces, for the purpose of reducing breakdowns, but all we know about these tracks is that they often are the bane of true speed horses, favouring come-from-behind plodders. They have made the outcome of races so unpredictable that they have driven the high-rolling, sophisticated gamblers away from the betting parlours; and they may or may not save horses’ lives. The jury remains sequestered.

All such expedients are aimed at forgiving commercial breeders for what they have done to the breed. At the core of the problem is the fact that the fastest and most popular sire lines in the world are the least durable and sound. The many lines that branch out from Native Dancer include names that fairly light up a yearling catalogue page and bring the highest prices, and Parker sees their presence and influence so much on the rise – so much Northern Dancer and Raise a Native, so much Danzig and Danehill, so much Nureyev and Sadler’s Wells, so much Storm Cat and Storm Bird – that she fears a gene pool grown narrow and dry, one in which it will be impossible to find a sound, viable outcross unless the grand pooh-bahs open up The American Stud Book, which has been closed to anything but purebred thoroughbreds for more than 100 years.

“You think The Jockey Club is going to allow something like that?” she asked. “Not hardly. What you have to deal with is what’s left, and what’s left is very little.”

In her latest issue of Pedlines, written after Eight Belles’ death, Parker wrote how such intense inbreeding to Raise a Native “creates nothing but tragedy. There is no good thing about it and there is no excuse for it. Dr. Larry Bramlage says he seldom sees injuries like this. Well, he better get used to it, because sales catalogues are full of this horrible cross. Breeders are either oblivious or think it’s inevitable. But what is really inevitable is that every time a Barbaro grinds a limb to a pulp, every time a Pine Island dies at the Breeders’ Cup, every time an Eight Belles’ death destroys the joy of a Kentucky Derby, we lose another chunk of what little fan base we have left.”
