Advice to Horse Owners: Be Objective about Obese Horses

(report provided by ILPH)

At the recent Scottish Equine Welfare Seminar of the International League for the Protection of Horses (ILPH) at the Royal (Dick) School of Veterinary Studies in Edinburgh, Robert Eustace FRCVS of The Laminitis Trust rattled the cage of equine obesity in the show ring and in the home paddock.

"Obesity – a major cause of welfare problems" was the title of his presentation.

Robert was able to graphically show the difference in what horse owners nowadays think is acceptable weight compared to forty years ago and even twenty years ago, by using winner photos from old and recent horse shows. The attendees were captivated by this visual proof of the changing form of horses shown in-hand (what we call "halter" horses in the USA).

Robert expanded on the damage that is occurring to these obese animals and their progeny, if indeed they were able to reproduce.

He concluded with some very basic sound advice to all horse owners: Every time your horse is shod, use your weight tape and mark on the stable wall the weight it shows. This will prove that the horse owner is keeping an accurate record of the weight at a regular interval so any weight gain or loss is easily detected.

Farrier Elmer Campbell Has Died

Elmer Campbell, one of the first farriers elected to the Kentucky Derby Museum's "Hall of Fame" for farriers, has died in Florida.

Elmer is shown in the middle in this photo with his twin sons Charley on the left (I think) and Joe on the right. This photo was taken at the 1985 Breeders Cup at Aqueduct. Both sons were shoers with their father at the New York tracks; Joe is still there and works as paddock farrier at Saratoga in August. Charlie died in 2005 after a long battle with cancer.

I will post more information shortly to add to this story.

New "TracMe" Therapeutic Horseshoe Hits Its Stride at Hoof Conference

The new "TracMe" aluminum wedge/roller horseshoe was unveiled today at the International Hoof Care Summit meeting in Cincinnati, Ohio.

The new shoes are sized like raceplates and look like therapeutic shoes. The larger sizes have wider (some would say onion-esque) heels and optional clips.

Trac Me is the project of metals manufacturing pro Mary Lovejoy of Versailles, Kentucky. A few years ago, her mare Zena developed laminitis and was a patient at Rood and Riddle Equine Hospital’s podiatry unit, under the care of Dr. Scott Morrison and farrier Manfred Ecker.

Mary became intrigued with the clinic's display of aluminum shoes made by Manfred, or offered by different manufacturers. And she thought she could do better. When Zena recovered, she became determined to bring her metal trades background to the farrier world, and TracMe shoes became a full-fledged business plan.

The preliminary shoes were designed by Manfred Ecker and tested by top farriers like Dr. Scott Morrison, Mike Wildenstein (Cornell University), Jay Thomlinson (Virginia) and James Gilchrist (Palm Beach Equine Clinic).

Aluminum milling has been a state of the art process for making shoes for almost ten years now. The demand for aluminum egg-bar shoes sent GE Forge and Tool’s KB shoe line to the top of the class when GE’s Bob Garner went high-tech and mastered the aluminum extrusion and computerized milling process. The result was a streamlined horseshoe that didn’t break because (in a nutshell) the aluminum “flowed” around the form of the shoe instead of across the form. Major improvement!

TracMe shoes retail for $36 a pair and up.

Magnetic Toe Clip Device Helps Farriers Position Shoe for Nailing

Our trusty reporters on the trade show floor at the farrier meeting in Cincinnati report that one of the most unique items they have seen is the "Shoe-Tru" device. It is an oversized toe clip with a magnet that adheres to the shoe.

Assuming that the toe of the shoe is "out there" with the toe of the foot, not set-back, the clip holds the shoe in placing for safer, more steady nailing. Once the nails are in, the farrier just slips the clip off the shoe.

Many farriers lament the unpopularity of toe clips on USA horse shoes; most people use side clips. Users of both types of clips site the ease of nailing on a clipped shoe. The magnetic clip may help with nailing, but not have the burn-in requirements of a "real" clip.

There are some ingenious people out there!

Barbaro's Final Update

At around 10:30 this morning, after spending a restless night on his feet in his stall at New Bolton Center, 2006 Kentucky Derby Barbaro was euthanized by his surgeon Dr. Dean Richardson.

I was able to participate in a press briefing from Dr. Richardson this afternoon and can share this information:

1. The decision to euthanize Barbaro was not related to a re-fracture of his leg. To take weight off his foundered left hind, Barbaro bore increased weight on the right hind and severely bruised the lateral heel, which lead to an abscess in that heel area.

2. Barbaro did develop laminitis in both front feet.

3. On Sunday night, Barbaro did not lie down. Richardson said the horse is usually quiet at night and lies down to sleep. He did not do that last night and Richardson said it was the first night the horse had been in distress. The horse's distress was in spite of pain medication and the use of the sling. "We couldn't control his pain," Richardson said.

4. On Monday morning, Barbaro was relatively comfortable in his sling and alert. He ate his grass brought to him by his owners. He was given a heavy dose of tranquilizer and then an overdose of anesthesia through a catheter that was already in his neck.

5. "It could not have been more peaceful," Richardson stressed.

In retrospect, Richardson commented, "There were some Eureka! moments. But this is how science works, it's more like a gradual accumulation of expertise. I am sure I made mistakes, or, I should say, I am sure there were things I could have done better. You have to believe that you will get better at your job, otherwise why would you go to work in the morning?"

Referring to the cascade of events leading to the decision to euthanize the horse, Richardson said, "It's like a deck of cards. If one thing starts to go, others follow."

"My only gratification," he said near the end of the conference, "Is that he had eight or nine months of being a happy horse a majority of the time."

The press conference ended about 4:30 this afternoon.

Barbaro's Last Update: Rest in Peace

Word just in that 2006 Kentucky Derby winner Barbaro was euthanized this morning at New Bolton Center. More information to follow.

What's Next for Barbaro: External Fixation for Collapsing Right Hind

Left: Barbaro's right hind leg as it appeared on radiographs in November. This leg is now equipped with an external fixation device for support; pins were surgically implanted through the leg to attach to a brace.

A sobering statement from New Bolton Center this morning:

"On Saturday, January 27, Barbaro was taken back to surgery because we could not keep him comfortable on his right hind foot. That foot developed a deep subsolar abscess secondary to bruising when he went through a period of discomfort on the left hind foot. It is not laminitis but the undermining of the sole and part of the lateral heel region are potentially just as serious.

"We attempted to manage the right hind foot in a cast and then in a custom fabricated brace but it was impossible to have access to the foot for treatment as well as acceptable stability and comfort.

"We elected to place his right hind in an external skeletal fixation device in order to provide the foot a chance to heal. This means that two steel pins have been placed transversely through his right hind cannon bone. These pins are connected to external sidebars that in turn are connected to a lightweight alloy foot plate. This results in the horse eliminating all weight bearing from the foot; the horse's weight is borne through the pins across his cannon bone.

"There is significant risk in this approach but we believed it was our only option given the worsening of the right hind foot problem. The major risk of the external skeletal fixation device is that the bone bearing the weight can fracture. Unfortunately, we felt we needed to take this risk because this approach offered our only hope of keeping Barbaro acceptably comfortable.

"He had a perfect recovery from anesthesia and has been in and out of the sling since then. His left hind foot appears to be stable at this time. We remain concerned about both front feet. Remarkably, his attitude and appetite were excellent overnight.

"We will continue to treat Barbaro aggressively as long as he remains bright, alert and eating. This is another significant setback that exemplifies how complex his medical situation remains because both hind limbs have major problems."

External fixation for laminitis and other conditions is not an unproven technique for New Bolton. The hospital's Dr. David Nunamaker is probably the world's leading expert on this type of support. Photos of similar fixations from Hoofcare & Lameness files will be added to this story when I am back in the office.

From Gretchen Jackson, owner of Barbaro, on Saturday:

"He's got a lot of issues, and not any of them is bad enough to say goodbye. But put together it's not a good day for Barbaro," Mrs. Jackson told Mike Jensen of the Philadelphia Inquirer.

Scott Morrison DVM, consultant on Barbaro's foundered left hind foot, was at home in Kentucky yesterday.

Journalist Jensen recently won an Eclipse Award, racing's highest honor, for his reporting on Barbaro. He is basically embedded at New Bolton Center, somewhere near the reception desk.

Stride Characteristics vs. Conformation: The "Deep Impact" Impact

Interesting report today from the Japan Racing Association, as presented this week at the Asian Racing Conference in Dubai:

(As posted on http://www.thoroughbrednews.co.nz)

"The success of Deep Impact, an unremarkable-looking racehorse, is down to his incredible stride, extensive scientific data revealed.

"Dr Hiroko Aida, from the Japan Racing Association, displayed the running form of Deep Impact in the veterinary science workshop at the 31st Asian Racing Conference in Dubai.

"A host of measurements were taken from high-speed video data of the Kikuka Syo (Japanese St Leger) at a rate of 250 frames per second.

"Sophisticated analysis has revealed that the champion racehorse’s ratio of overlap time to stride duration was 8.5 per cent, compared to that of an average horse, which is 17.1 per cent.

"It was postulated that this characteristic, which is also common to the great American horse Secretariat, may be an essential feature of superior horses.

"Aida said that such video analysis could in the future identify the “next Deep Impact” before he hits the sale ring."

Editor's Note: Deep Impact was Japan's superhorse. He retired this fall with earnings of 1.5 billion yen (about $13 million US). When Deep Impact traveled to France this fall for his gallant third-place finish in L'arc de Triomphe, chartered jumbo jets full of his fans accompanied him. Deep Impact is one of many stakes-winning offspring of American champion Sunday Silence, who stood at stud in Japan before his death caused by laminitis.

Barbaro Update: Cast changes, heel abscess in right hind

From the University of Pennsylvania today:

“Barbaro was placed under anesthesia yesterday to have his left hind foot cast replaced,” said Dr. Dean W. Richardson, Chief of Surgery. “We also removed the cast on his right hind leg and replaced it with a custom-fabricated plastic and steel orthotic brace to give his foot additional support.” An abscess near the lateral heel of his right hind foot was drained, and the brace that was applied will allow more regular treatment of that foot.

“Barbaro had another smooth pool-recovery and has been comfortable with an excellent attitude and appetite since then,” said Dr. Richardson. “We will probably replace his left hind foot cast under anesthesia again at least two or three times at roughly two-week intervals if his comfort is maintained. We were very pleased with the progress of his left hind foot since the last cast was applied.”

In addition, new shoes were placed on both front feet for additional support.

Waltham and Royal Veterinary College Organize British Laminitis Conference in March

(edited from press release received 25 January)

The WALTHAM^® Equine Studies Group and the Royal Veterinary College have joined forces to host a laminitis conference at The Royal Veterinary College at North Mymms, Hertfordshire (England) on Saturday 24 March 2007. Targeted at vets, researchers and others interested in the condition, the conference includes recent research findings and advice with respect to laminitis.

Pat Harris PhD MRCVS, head of the WALTHAM^® Equine Studies Group will chair the conference; she said: "This conference should bring you up to date with the current thinking on the pathophysiology of laminitis and how to manage affected animals. In addition, we will provide exciting new insights into ways that may help us to predict which animals are more likely to suffer from this debilitating condition, as well as management strategies that may reduce the risk of an episode occurring."

The program covers key aspects of laminitis, its possible causes and management regimens. Dr Annette Longland BSc, PhD will discuss "Starch, sugar, and fructans: what are they and how important are they?". Jonathan Elliott MRCVS (Professor of Veterinary Clinical Pharmacology) will look at new insights into the cause. Ray Geor PhD, DACVIM will examine the role of obesity and insulin resistance. Pat Harris will cover the nutritional counter-measures to laminitis. Celia Marr PhD, MRCVS will examine the medical management of the acutely laminitic Horse. Simon Curtis FWCF HonAssocRCVS will explain the role of the farrier in the management of laminitis. Nicola Menzies-Gow MRCVS (Lecturer in Equine Medicine) will provide insights based on various laminitis field studies. Jonathan Elliott will present a paper by Simon Bailey MRCVS (Lecturer in Veterinary Pharmacology) examining how an increased risk of suffering from this condition may be predicted now and in the future.

To register for the conference please telephone Kerry Knight on (011+ from the USA) +44 (0) 1908 576258. The fee is £30 (approximately $60US), which includes lunch and a full copy of the proceedings.

EDITOR'S NOTE: The Royal Veterinary College (RVC) is the UK's first and largest veterinary school and a constituent College of the University of London. Equine laminitis has been a focus for researchers at the College for the past 15 years. The research team involved includes pharmacologists, endothelial cell biologists, bacteriologists, endocrinologists and epidemiologists. The group has made significant steps towards understanding the link between events in the gastrointestinal tract and failure of the dermal-epidermal bonds within the hoof laminae. Recent work has turned to understanding the factors making some horses and ponies particularly susceptible to bouts of laminitis.
