Shoeless Thoroughbred Wins at Keeneland; Track Lists Barefoot Entries as Trainers Experiment with Polytrack Surface Effects on Hoof Slide

The racing surface known as "Polytrack" is one of several artificial surfaces that have been installed at racetracks in North America to improve safety and help cope with bad weather. But it also changes the way the hoof interacts with the surface. The characteristic slide that horses experience on dirt can be "sticky" for some horses. Experimenting with and without shoes during training and racing has led some trainers to try some unorthodox combinations of shoes--or no shoes at all.
Update: A second "no shoes" designated horse won a race at Keeneland on Sunday, bringing the total of winners to two in three days. Updated information has been added at the end of this article.

Paynter Watch: Top Thoroughbred Colt Diagnosed with Post-Colitis Laminitis in New York

You could hear a collective moan rise from the world of Thoroughbred racing today.

Paynter has laminitis.

For the past month, the racing press has been reporting on the condition of top three-year-old colt Paynter, trained by California's Bob Baffert. Paynter is owned by Zayat Racing Stable.

After winning the Haskell Invitational at Monmouth Park in New Jersey on July 29, the colt was transferred to a New Jersey vet clinic, then released a few days later. Few details about his condition were available but it was clear that both his connections and his fans hoped to see him run in the Travers Stakes at Saratoga.

Paynter was sent to Belmont to recover and then moved to Saratoga, where he was reported to be in light training.

However, last week Paynter was admitted to the Upstate Equine Medical Center in nearby Schuylerville, New York. It was confirmed that the horse was suffering from colitis, a severe infection of the horse's digestive tract that involves extensive and debilitating diarrhea. Severe and sudden laminitis is a common side-effect of colitis in horses.

A moving tribute to the colt spontaneously erupted on Twitter as hundreds of people tweeted the mantra-like hashtag, "#PowerupPaynter" throughout the weekend.

It seemed like a miracle when, on Monday, the owners tweeted that the horse was improving.

In what might be a new trend for news gatherers in horse sports, the horse's condition has been reported via the Twitter accounts of Justin and Ahmed Zayat.

Earlier this afternoon, Justin's flying fingers tweeted, in poignant 140-character bursts:

"Unfortunately we have a very sick horse who has developed serious complications in the last 24 hours. 

"Other than fighting bravely his colitis, he continues to have diarrhea as well as his protein blood level is very low. We continue to give him plasma to help him out. His blood work continues to be good as well as his temp so on a standalone basis he is fighting bravely and hard...

"...He is developing a new issue about his veins being swollen, a disease that is called DIC which stands for 'disseminated intravascular coagulopathy'.

"...The most concerning news is as of last night he started becoming sore on his left foot and was scared to turn around and walk on it..unfortunately we only thought it was some swelling...but it has worsened because today he has been diagnosed with our nightmare scenario of laminitis.

"...It seems it is rapidly progressing after...additional x-rays of the foot and discussing with some foot experts, Dr. Laura (Javsicas) (has) found out that he has developed it in three of his four legs, which is heartbreaking. 

"...Poor Paynter, I don't know how long he can fight this out so bravely without having pain and suffering. So far (Dr. Laura) is very conscious of that and having his pain under control. 

"But we need to look at all these problems. My deep concern is that if he is a healthy horse he can fight laminitis since it is the beginning but to be a sick horse and fight all these issues all at once, it is asking for too much. 

"We need to be compassionate and merciful and treat our star with the respect and love that he deserves while giving him the best chance in fighting for his life."

The prognosis for horses suffering from colitis is grim. Acute post-colitis laminitis can be especially sudden and severe and bears little resemblance to laminitis seen in otherwise healthy horses.

Ice baths have been documented in Australian Equine Laminitis Research Unit studies to prevent laminitis in horses with colitis. As described by Mark Andrews MRCVS in Equine Sciene Update

"One treatment that (Dr. Chris) Pollitt has shown to be effective in preventing laminitis is cryotherapy, using iced water....

"'It is important that the ice water comes up to just below the knee. If only the foot is cooled laminitis still occurs.

"'We don't yet know how long this protective effect would last. But horses with toxic colitis (which often causes laminitis) have been treated successfully with an ice-water bath. The clinicians involved believe that it has prevented laminitis.'"

Paynter appears to be wearing ice boots on his legs.

Hoofcare University: Biomechanics of Racehorses' Lower Limbs and Track Surface Interface Video Lectures with the University of Guelph's Dr Jeff Thomason

Dr Jeff Thomason
Go get a cup of coffee or a sandwich or start popping the corn. Hoofcare + Lameness is happy to share a new video series with you from the University of Guelph's Jeff Thomason BA, MSc, PhD, professor of biomedical sciences at Guelph's Ontario Veterinary College.

Dr Thomason is widely known for his research, which currently looks both at the biomechanics of the horse's foot and distal limb as well as the mechanical properties of the track itself, and how they influence the function of the foot.

Recently, Dr. Thomas was part of a group of authors that created an extensive "white paper" reference document for the Grayson-Jockey Club Foundation's Welfare and Safety of the Racehorse Summit on this type of dual research, which will ultimately benefit the safe travel of horses over optimal racing surfaces.

Plan to spend the next 15 (or so) minutes absorbing Dr. Thomason's lecture points, which have been broken down into bite-size videos.

Introduction:


How do you examine limb mechanics?


How do banked surfaces affect impact?


Can optimizing track surface reduce catastrophic injury:


Who will benefit from the racing surfaces 'white paper'?


What is the best track surface for racing?


How does climate affect track surfaces?


How does maintenance affect track surfaces?


To learn more:

Inside the Thoroughbred Racehorse: Just Watch This!


Of course you have never taken the Thoroughbred athlete for granted, but after watching this 48-minute documentary, you'll be in even more awe of the complex biomechanics and physiology of the running Thoroughbred. Anyone who's squeamish in a dissection might want to skip over this, but you'll miss a lot!

This documentary, part of the multiple award-winning Inside Nature's Giants series broadcast on Britain's Channel 4 over the past three years, is hosted by veterinarian Mark Evans. Hoofcare + Lameness readers may recognize contributors Renate Weller and Alan Wilson, two leading veterinary researchers at the Royal Veterinary College in England.

Farrier Billy McQueen has a few minutes on screen.

There are several sections of the documentary that focus on the racehorse foot. This clip (below) details the function of the flexor tendons in moving the limb and hoof forward, not the anatomy of the foot itself, but it has some great animation and a startling demonstration by Alan Wilson and a scalpel.



You might not agree with the way that everything is presented on this video. Students of equine evolution may be surprised at the way presenter Richard Dawkins (6:06 in the full video) describes the progression of the hoof from multi- to single-toed (the way that everyone was taught in Pony Club). It must be easier to explain it to a television audience as if the horse just kept dropping toes to run more efficiently. Weightbearing theories that include the horse employing more than just the hoof wall are not mentioned, either. But the producers had the task of explaining a running horse in 48 minutes to a universal audience, so this is pretty general information in some parts.

You'll have to watch the entire documentary to see all the information on the foot. But it's all connected. Don't miss a minute of this documentary, even if you're sure you know it all. You just might see it presented in a new way.

Are you a professional who works with horses--a farrier, trimmer, veterinarian, vet tech, gait analyst, or bodyworker? Or an educator? This video is highly recommended to explain to anyone who doesn't "get it", why you do what you do: because the athletic horse is simply the most amazing creature on earth.

Note: the video team made a stop at the breeding barn at Coolmore Stud in Ireland, so if you are sensitive to what goes on there, or have children or students who might be, you might want to skip over that part.

Travers: Shackleford Sticks with Glue-on Shoes for Summer's Biggest Thoroughbred Race; Horseshoe Technology Exciting Area of Track Safety, Health Innovation

The feet of a survivor: Shackleford ran in all three Triple Crown races in 2011, and provided some exciting memories. He won the Preakness in May wearing polyurethane glue-on Polyflex shoes, thus becoming the first Triple Crown winner to cross the finish line first in non-metal glue-shoes. The shoes appear rather amber-colored in this photo taken by Sarah K. Andrew (Rock n Racehorses) last week at Saratoga. The urethane is transparent, and shows a thin metal wire embedded in the plastic; the shoe also has a wear plate at the toe. Shackleford is shod by New York-based horseshoer Brad Dewey. The whitish patch on the colt's heel quarter is adhesive. Shackleford is a very large colt, an imposing equine specimen who could have a second career as a photo model. His face is marked by a wide white blaze with a triangle at the top, giving his face the appearance of a arrow pointing to the sky. He's easy to spot in a race. His namesake, an island off North Carolina populated by wild horses, is probably underwater right now.
News just in: That handsome Shackleford will race in today's Travers Stakes at Saratoga in his favorite high-tech run-a-red-streak horseshoes. Trainer Dale Romans confirmed this morning that his big red colt will stay in his Polyflex glue-on shoes, in which he won the Preakness Stakes in May. That was the first win of a Triple Crown race by a horse in plastic glue-on shoes. Let's look at it again:
2011 Preakness Stakes: first Triple Crown race won by a horse wearing glue-on and/or plastic horseshoes; Big Brown won the Kentucky Derby and Preakness with his aluminum shoes glued on.
There was some uncertainty, apparently, in the Roman camp that Hurricane Irene might arrive in time to turn the Spa to soup, but Irene is busy elsewhere and the rains aren't predicted to begin until long after the sun sets in upstate New York. A wet track, however, didn't impede Curlin when he won the Jockey Club Gold Cup in the same type of glue shoes in 2008. I still miss that horse. Just for old times' sake, watch him win that race, which catapulted him into the #1 spot in all-time money-earning racehorses:
2008 Jockey Club Gold Cup Stakes at Belmont Park won by Curlin in plastic glue-on horseshoes over an off track; Curlin also wore the shoes when he won the Woodward that year.
The first stakes horse to run in glue shoes was Afleet, back in the 1980s; his trainer opted for the Mustad Easy-Glu. Since then, horseshoers at racetracks have had success with a variety of raceshoes adapted for glue, and in even directly gluing aluminum raceplates to the foot. Experimentation with glue shoes (rather than nails) goes back to the 1800s. Most experimentation has been done in Germany, which also gave rise to the newest era of glue shoes when the Glu-Strider emerged there in the 1980s. That shoe was developed by a creative engineer and horse owner named Peter Steubbe; the technology was quickly purchased and continued in research and development of a full line of shoes by hoofcare giant Mustad International.

Glu-Strider technology was based on a Super Glue type adhesive, while the current generation of shoes uses two-part PMMA-type adhesives. PMMA is the family of adhesives that includes the glue used by women to hold artificial fingernails to their nailbeds. The innovation and experimentation in footwear is one of the most exciting areas of developing health and safety innovations in racing today. At the same time, the Association of Racing Commissioners International is considering a model rule to allow horses to run without shoes. Currently, barefoot racing is outlawed in about half the jurisdictions in North America. The Grayson Jockey Club Foundation's Welfare and Safety of the Racehorse Summit has kept shoeing and hoofcare in its sights since the consortium was founded in 2006. The Summit has an ongoing and active Shoeing and Hoof Care Committee that meets regularly and consults on shoeing-related matters affecting Thoroughbred racehorses. A sub-committee is tackling the possibility of a uniform, nationwide racetrack shoeing licensing program and test, and is currently seeking input from the industry. Mucho Macho Man and Nehro are two other Triple Crown contenders who ran in glue shoes in 2011. Top older stakes horse and candidate for Horse of the Year Tizway, winner of the Metropolitan and Whitney, also wears the Polyflex shoes.

The racehorse Shackleford has probably never been anywhere near the Shackleford Banks off the North Carolina coast. And with Hurricane Irene in the neighborhood, he wouldn't want to be there. The area is famous for the wild horses, called Banker Ponies, that freely roam the dunes there. Photo courtesy of Kurt Repanshek and NationalParksTraveler.com.
Glue-on shoes are now so ubiquitous  at the track that it's hard to find out when horses win in them. We found out about Shackleford in the Preakness, after the race was over; he was shod by Brad Dewey. Horseshoes aren't as visible as a tack change or new style of blinkers or Zenyatta's ear plugs, so the news of innovative horseshoes isn't always obvious.
Here's a partial list of stakes horses who won their races (some set track records) wearing the Polyflex glue shoes: Ambitious Cat, Bargain Baby, Big Booster, Brother Derek, Buzzards Bay, Charitable Man, Cry and Catch Me, Cowgirls Don't Cry, Cubera, Divine Park, Dream Play, Eldaafar, Essential Edge, Ever Elusive, Foxysox, Fredaville,Golden Yank, Greeley's Conquest, Hold the Salt, Hot Dixie Chick, Indian Blessing, J Be K, Kandar Du Falgas, Kensai, Lantana Mob, Little Belle, Lucky Island, Luna Vega, Major Rhythm, Malibu Mint, Mo Cuishle, Mr Fantasy, Nehantic Kat, Noonmark, Octave, Osidy, Pray for Action, Present Danger, Pyro, River's Prayer, Roses 'n' Wine, Secret Gypsy, Set Play, Seventh Street, Shaggy Mane, Silent Name, Sok Sok, Stormin Baghdad, Stream of Gold, Student Council, Total,  Teuflesberg, Uno Mas, Wow Me Free, and Zanjero. (Names harvested from the Polyflex web site.) Favorite little known fact about Polyflex glue-on shoes: Both Curlin and his beloved stable pony Pancho wore them! Nothing but the best for the champion's best friend! Watch Shackleford and all the top three-year-old Thoroughbreds entered in today's Travers Stakes at Saratoga on NBC Sports at 5 p.m. Lots of news about the race and the track on www.nyra.com.

Sarah is a frequent contributor to the Hoof Blog and keeps a key eye on the hooves at the track. Her track and sport horse photography is nothing short of phenomenal; Sarah is also a key ingredient in the success of Camelot Weekly, the all-volunteer program at the New Jersey horse auction that channels racehorses, sport/recreational horses, and companion horses into new homes instead of the killer pen--via Facebook! Sarah photographs the horses available each week, without compensation, and I wish a book publisher would make a coffee table book of these portraits of horses in need. They have saved thousands of horses from slaughter; not one horse from that auction has been re-routed to slaughter since they began.

The Unshod Racehorse: Racing Commissioners Table Model Rule on Barefoot Racehorses


When the Association of Racing Commissioners International (RCI) met at the Holiday Inn in Saratoga Springs, New York on Tuesday, the state regulators had Lasix on their minds. But after lunch, the meeting turned to the model rules that had been proposed for 2011. 

Model Rule 5 proposed allowing horses to race without shoes. It has a proviso attached to it, however: a horse that runs in a race unshod would not be able to race in shoes for 60 days. This requirement seemed to be based on the way that Lasix is handled rather than on the way that equipment changes like bar shoes or blinkers are handled, although their requirements may vary between states as well.

After some discussion, the decision was made to table the rule proposed at Saratoga.

The state of California has gone through an extensive period of evaluating the decision whether or not to allow horses to race without shoes. The question of allowing the practice came up in November 2007, when the state was installing artificial surfaces on the major racetracks. In February 2008, Dr. Diane Isbell, one of the CHRB’s official veterinarians, spoke on behalf of trainers who were training horses without shoes and wished to race without shoes. She also listed some of the improvements seen in the horses training without shoes.

California initiated a temporary open-rule period, with records of unshod horses compiled for reporting to the California Horse Racing Board. During the trial period, data was collected on 211 horses racing in the state, of which 172 were unshod in all four feet, 27 wore shoes in front and not behind, 4 ran with only hind shoes, and 8 horses were running with shoes after having previously raced unshod.

In terms of success of these horses, 77 of the 211 finished in first, second or third place in their races, while 24 finished last and 10 horses were scratched. The great majority (191) of the horses ran at Golden Gate Fields.

At the time that California was considering this rule change, the CHRB found that 13 states and/or tracks allowed horses to race barefoot, with restrictions and stipulations varying between the states. Twelve states or tracks required that horses be shod.

A model rule is not the same as a rule. A model rule gives each racing jurisdiction a framework, or suggested text for a rule, based on the research and expertise of committees within or attached to a larger group like the RCI. So that each state does not have to go out and research a subject, it is provided a model rule that has gone under scrutiny of the RCI system.

Documents from the California Horse Racing Board were referenced in preparing this article. Thanks to Teresa Genaro

Racehorse Fetlock Screening Via Standing MRI Could Identify Horses at Risk for Condylar Fractures of the Fetlock


If there is one thing that we all learned by watching the Kentucky Derby this year, it was the term "condylar fracture". Watching first Battle of Hastings and then Archarcharch load into the horse ambulance was the low point of the day.

Are you one of the people who just shrugs and says, "That's racing!" or are you one of the people who asks, "Why? Why? Why?"

Maybe this article will raise the eyebrows of people in both camps and get them both saying, "What if..."

So what if...

What if a standing MRI could help identify horses with potential fetlock problems before any injury ever even happens? It's possible, and that's the prospect that equine practitioner John Peloso of Equine Medical Associates of Ocala, Florida put forward in March in an article in Thoroughbred Times.

Little did he know how timely the article would be six weeks later!

Let's start with the injury. Condylar fracture means that the portion of the long bone that was broken was the condyle. When you look at the end of the cannon bone, you see a ridge in the middle, between two rounded bulbs, called condyles.

The fetlock joint surface can be subject to a lot of wear and tear, as well as evidence of a degenerative condition, that might now show on a radiograph but might be visible via MRI. (John Peloso DVM photo)

The condyles sit in the fetlock joint and rotate within it, like balls in a socket, as the horse flexes his lower leg. Battle of Hastings' fracture was the medial (rough translation: inner side of the limb) condyle, whereas Archarcharch's injury involved the lateral  (rough translation: outer side of the limb) condyle.

Racehorses are especially prone to condylar fractures. Something (trainers like to call it "a bad step") causes increased pressure on the condyles in the fetlock joint. Normally a horse is fine but sometimes the condyle fractures, to varying degrees. A radiograph will show what looks like a crack in the cannon bone in the condyle area.

Thoroughbreds "Make It or Break It"

In his article, Dr Peloso reminds us that the process of building and creating an equine athlete is dependent on the horse's ability to "remodel" his bones.

The rigors of training cause a horse to continually lose bone and then replace it. In a healthy normal horse, the resulting replacement is more dense than the original.

But in some horses, the lost bone is not adequately replaced or fortified. This is called non-adaptive bone modeling. The effects of training may actually weaken the bone rather than fortify it.

If you have looked at a good radiograph of a horse's fetlock and cannon bone, you know that bone has different density values, and yet the inadequate bone modeling syndrome is deep in the bone and difficult for a radiograph to show. The depth of the problem means that the tissue around the joint doesn't swell, either. It's invisible.

MRI scans the fetlock in 3-D

Which horse would you bet on? The horse on the left had not begun training; the horse on the right shows mild thickening of the subchondral bone in the condyle region. (John Peloso photo)
Dr Peloso recommends the use of standing MRI to evaluate racehorses. MRI scans the fetlock in three dimensions and shows what's going on with the soft tissue in and around the joint as well as the architecture of the bony column itself. And with standing MRI, the horse does not need general anesthesia; trainers are reluctant to schedule their horses in training for anesthesia.

Standing MRI allows the horse to stand in a natural position while the scanning goes on. The horse is sedated but does not need general anesthesia. (Hallmarq Veterinary Imaging photo)

Certainly there is no way to know how many injuries can be prevented by monitoring fetlocks for non-adaptive bone remodeling. But in human medicine, MRI is the modality of choice to routinely detect almost-invisible stress fractures in athletes.

Dr Peloso noted that standing MRI screening of the fetlock is commonly performed in England, Ireland, France and Dubai, where many vet clinics are equipped with standing MRI units and may screen as many as two to three racehorses per day.

What veterinarians like Dr. Peloso hope to help trainers avoid: two examples of the early stages of condylar fracture of the fetlock. The red arrows are pointing to white crack-like lines that indicate a fracture has begun. (John Peloso photo)
Of course, you have to wonder why this happens at all: why are some horses normal? Why is it that the bones in other horses--horses who look and act perfectly healthy--just don't adapt properly?

Those are big questions. MRI can't answer those but a racehorse monitoring protocol of standing MRI sounds like a hopeful proposal that could possibly save some American horses' lives, careers or months lost from training. It could be that famous "ounce of prevention" that is worth many pounds of surgery, layup and rehabilitative cure.

Laminitis-Survivor Overdose Wins in Germany, Sets New Course Record

Overdose, the Hungrian wonder horse who survived a long layoff for what was described as laminitis, broke a track record in Germany yesterday. (Photo via Flickr.com's Gabor Dvornik)
Some quick good news for a Sunday afternoon: Hungarian wonder-horse Overdose is back to his winning ways. Once undefeated, the horse went into an extended layup when he was suffering from some form of laminitis, as reported on this blog last May. Last year he suffered his first defeat but yesterday, after another seven-month layup, he not only won, he set a new course record!

Much of Overdose's successful return to racing had been credited to his American glue-on shoes, made by Sound Horse Technologies, and his British farrier, Stuart Packham who is apparently something of a national hero in Hungary.  I don't know if Stuart is still with Overdose, but something is working.

In a race last year, Overdose lost one of his glue-ons during the race but still won. I think that lost shoe was the most famous shoe story in many years!

Stuart Packham's shoeing of Overdose was featured in a step-by-step story in one of the many Hungarian blogs about Overdose. (This is not meant to be an advertisement for the shoes; it is a great photo story for anyone who'd like to see one of these shoes applied.)

The Racing Post, as usual, has more details about yesterday's win. It sounds like he may be headed for Royal Ascot if all goes well. Wouldn't you love to see him against Black Caviar?

Necropsy Report: British Horses Died of Cardiac Arrest; Signs Consistent with Electrical Shock from Leaking Cable Under Paddock


The British Horseracing Authority has provided a summary statement following the completion of necropsy studies on the bodies of two horses that died at Newbury Racecourse in Berkshire, England on Saturday. The horses collapsed and died as the jockeys were preparing to mount; two other horses fell but were able to recover.

Professor Tim Morris, Director of Equine Science and Welfare for the British Horseracing Authority, issued this prepared statement today:

“The Authority has been officially informed that there was leakage of electricity from a cable under the parade ring in the area where the incident occurred. There was immediate veterinary attention, and our enquiry on the day noted the racecourse veterinary surgeons felt a tingling sensation when examining the horses, and that the veterinary surgeons noted particular clinical signs such as muscle contractions.

“Both horses that died, Marching Song and Fenix Two, have undergone postmortem examinations which showed sudden cardiac arrest as the cause of death. Samples taken from the horses affected have shown no evidence of substances that could have caused this incident. These findings are all consistent with the cause of death being accidental electrocution and at this stage we are not investigating any other cause of death.

“I can also confirm that, contrary to speculation, no evidence of any burn marks around the mouth was found on post mortem examination, neither were such marks found by the veterinary surgeons on the horses at the start.”

The necropsies were performed by pathologists at the University of Liverpool’s School of Veterinary Science with additional services from the British Horseracing Authority contractor HFL Sport Science.

Much speculation has surrounded whether the horses' shoes were part of the formula that led to their death. Metal horseshoes are known to conduct electricity; horses are especially susceptible to electrical shock. Some people have speculated that the fact that the horses who died were shod with steel shoes, while the horses who survived were shod with aluminum, may have been a factor in the tragedy.

So far, there is no proof that that is the case.

Aluminum Shoes May Have Saved Two Horses' Lives as Two Steel-Shod Horses Die in Possible Electrocution at British Racecourse

Video by ITN.

The worlds of both sport and horses were rocked today when news came from England that four horses had become agitated for no obvious reason in the paddock before the first race at Newbury Racecourse in Berkshire. The horses began rearing and falling as the jockeys were mounting. Within minutes two horses had died while two others rose back to their feet. 

The rest of the horses continued to the start and the race was run, but track officials canceled the remainder of the program for the day. Rumors began immediately that the horses had been electrocuted, and that a groom had felt a shock come through the horse's body, and a lead line showed burn marks.

According to the Racing Post, unconfirmed reports suggested that some of the runners who actually took part in the race appeared to have burn marks around their mouths when their tack was removed.

In an interview late on Saturday, Joint Managing Director of Newbury Racecourse Stephen Higgins commented on the shoes worn by the four horses affected in the incident. He said that the two horses that died were shod with steel shoes. The two horses that went down and got back up were shod with aluminum shoes. The two metals would conduct electricity differently if a shock was transmitted through the grass.

He also mentioned that because horses have four legs instead of two, they are much more sensitive to electricity in the ground, and that that would explain why humans might not have noticed the electricity. There were also rubber mats on the ground which the horses were stepping off onto the grass when the incident occurred.

Commenting on the incident, Professor Tim Morris, Director of Equine Science and Welfare for the British Horseracing Authority, confirmed that a full investigation is under way: “Following the tragic events at Newbury today, our sympathies go out to connections of the two horses that died, Fenix Two and Marching Song.

"We have launched a full investigation into the events before the first race. Whilst there are suspicions that an electrical fault was the cause and this is being looked into by the racecourse and relevant authorities, it is important that we investigate other possible causes.

"Both horses have been sent for post mortem examinations and samples from both horses, and from the other two horses involved in the incident, have been taken and will be analysed. We will also be testing a sample of the water supply and have secured and will review all of the CCTV footage from the racecourse stables and footage from the parade ring itself at the time.

"We have gathered evidence and statements at the racecourse from the connections involved with the incident, including trainers, jockeys, stable staff and owners, the racecourse and BHA veterinary officers, and the racecourse executive including the health and safety officer."

On its Facebook page, the racecourse posted this message to the public:

"The whole team here is totally devastated and our condolences are with everyone connected to the horses and those that saw this happen. The Electricity Board are carrying out investigations now and a further statement will be issued tomorrow."

The British Horseracing Authority quotes Jonjo O'Neill, trainer of Fenix Two, as saying: "Kid Cassidy was in front (leaving the paddock) and he took a turn. We thought he was bucking and kicking and he went down on his knees then he seemed to be OK. Mine reared up and we couldn't get him back, it was like he was stuck to the ground. It was the weirdest thing I've ever seen in my life."

Marching Song's part-owner Graham Thorner said: "I was very fond of him and he had great potential. To a layman with no evidence, you would say it was electrical. The lad who was with him was saying 'I'm getting an electric shock off this horse'. It can't be coincidence four horses have done the same thing and two have died, all in the same area."

Press assistance from the British Horseracing Board was instrumental in preparing this report.

¿Habla usted del casco? Grayson-Jockey Club DVD on Thoroughbred Hooves Now Available in Spanish

The DVD is one segment of the Shoeing and Hoof Care Committee's efforts to study and improve the safety for racehorses through hoof-related education.
The Welfare and Safety of the Racehorse Summit’s Shoeing and Hoof Care Committee has released a Spanish-language version of its educational DVD, The Hoof: Inside and Out, entitled, El Casco: Por Dentro y Por Fuera.

“Spanish-speaking individuals constitute a significant percentage of our horses’ caregivers, so it is only natural and in the best interests of the industry to provide a Spanish-language version of our hoof care DVD,” said Bill Casner, Thoroughbred owner/breeder and chairman of the Summit’s Shoeing and Hoof Care Committee. “We hope the Spanish-language version is embraced as enthusiastically as the original, because it will further enhance the care our horses receive on a daily basis.

The Hoof: Inside and Out was released in June 2009. Since then, more than 1,000 copies on DVD have been distributed and the online version has been downloaded more than 2,500 times by individuals in 57 countries.

Both the English- and Spanish-language versions can be downloaded at no charge at www.grayson-jockeyclub.org/summitDisplay.asp?section=39; or a physical copy can be ordered through that website for a $5.00 shipping and handling fee.

The 65-minute DVD includes seven segments:
* Introduction and Overview
* Welfare and Safety of the Racehorse Summit
* Physiology — The Equine Limb
* Basic Hoof Care and Trimming
* The Basics of Horse Shoeing
* Types of Shoes
* Farrier’s Role and Communication (with trainers and owners)

The DVD features the insights of a number of hoof experts and industry professionals, including Mitch Taylor, director of the Kentucky Horseshoeing School; prominent Kentucky-based farriers Steve Norman and Colby Tipton; Dr. Scott Morrison of the Podiatry Center at Rood and Riddle Equine Hospital; Dr. Sue Stover of the University of California-Davis School of Veterinary Medicine; Dr. Mary Scollay, equine medical director for the Kentucky Horse Racing Commission; Kentucky Derby winning trainer John T. Ward; champion Thoroughbred owner and breeder Bill Casner; and Grayson-Jockey Club Research Foundation President Ed Bowen.

The Welfare and Safety of the Racehorse Summit, coordinated and underwritten by Grayson-Jockey Club Research Foundation and The Jockey Club, convened a wide cross-section of the breeding, racing, and veterinary community for two-day workshops in October 2006, March 2008 and June 2010.

The Summits, which were hosted by Keeneland Association, have been the catalyst for many initiatives that improve the safety and integrity of the sport, including the Equine Injury Database, the Racing Surfaces Testing Laboratory, recommendations concerning traction devices on front shoes, and bloodline durability indices.
