Hoofcare & Lameness Presents World Horse Welfare's Laminitis Video Conference (Part 2)

"Recognizing the Early Signs of Laminitis" is the second in a series of feature presentations designed to help horse owners recognize the signs of laminitis in horses and to work toward preventing laminitis. In this video, British veterinarian David Catlow shares his insight from working with horse owners, and explains what conditions can fool a horse owner into thinking that a horse is just routinely lame rather than suffering the onset of a serious, life-threatening disease.

These videos were filmed at a lamintiis awareness seminar organized by World Horse Welfare and British feed company Dodson and Horrell earlier this year. More videos from the series will be posted on the Hoof Blog in the next few days.

The conferences, which were held at leading UK veterinary universities, were organized by Dr Teresa Hollands, Senior Nutritionist at Dodson and Horrell. Featured specialists included Professor Derek Knottenbelt, Dr Cathy McGowan and Alex Dugdale from the University of Liverpool, David Catlow from Oakhill Veterinary Centre and Samantha Lewis from World Horse Welfare, among many others.

The videos in this series include “The Horse’s Foot and How it Goes Wrong” (Professor Knottenbelt,) “Managing your Laminitic and Minimizing his Pain” (Dr McGowan,) “Recognizing the Early Signs of Laminitis” (David Catlow,) “Using Ultrasound to show the Difference Between Fat and Muscle” (Alex Dugdale,) and “How to Fat Score a Horse” (Samantha Lewis.)

Liverpool's Professor Derek Knottenbelt Speaker at Michigan State University Vet School

Each year, the Michigan State University College of Veterinary Medicine's Equine Division invites a visiting Freeman Scholar to visit MSU-CVM to provide seminars and informal instruction to the large animal faculty and residents.  This year Professor Derek Knottenbelt from the Leahurst Equine Hospital at the University of Liverpool in England will be at the East Lansing campus from Wednesday October 20 through Friday October 22.

Professor Knottenbelt will be giving two seminars for faculty and students at the College of Veterinary Medicine and he will also be the speaker for the October 20 evening program of the Michigan Equine Practitioners Association.

The topics of Knottenbelt's lectures will be "Equine Sarcoids" and "Role of Working Equids Around the Globe – Why Should We Care?"

Biography: Professor Knottenbelt graducated from the University of Edinburgh's Royal (Dick) Veterinary College in 1970. After a four-year spell in his native Zimbabwe working in the State Veterinary Service as a research officer, he moved into private practice in the UK where he stayed for 12 years. During this time he developed an interest in equine medicine and so, in 1985 he turned to the academic world, first in Zimbabwe and, after 1989, at Liverpool.

Professor Knottenbelt‘s expertise in equine internal medicine is recognized both nationally and internationally, particularly in equine oncology and dermatology. He is a Diplomate of the European College of Equine Internal Medicine and holds a personal Chair in Equine Medicine at the University of Liverpool. He has published widely in journals, authored 13 equine veterinary medicine textbooks and is frequently invited to speak at national and international meetings.

Knottenbelt received the Animal Health Trust Scientific Award in 2003, the BEVA (Blue Cross) Welfare Award in 2004 and the OBE in the Queen’s Birthday Honors of 2005 for his services to Equine Medicine. He is actively involved in many domestic and international charities relating to equine welfare and works tirelessly to support these causes.

His most recent effort was organzing a mad motorcycle relay of ten senior academic and private-practice veterinarians around England and Scotland to present research education at vet schools. The "Horsepower CPD" vets delivered their lectures in their motorcycle leathers and then sped off to the next university. The purpose was to benefit the British Equine Veterinary Association's fund-raising efforts and to help establish a therapeutic riding program for handicapped children in Mali, where Knottenbelt volunteers for part of each year as an equine education outreach provider. The lectures were free but donations for the funds were requested and the tour was partially sponsored by Petplan. The volunteer lecturers visited seven vet colleges in six days and planned to raise 60,000 pounds for charity.

A special service provided by Professor Knottenbelt is a web site he created to help horse owners around the world who have horses affected by sarcoids. Sarcoids affect as many as seven percent of the horses in Great Britain; that is a higher per capita infection than other countries. Sarcoids seem to be a growing concern in the United States, as well.

Knottenbelt is particularly astute on subjects related to dermatology of the horse's foot; he also has a keen interest in laminitis and worked with World Horse Welfare and Dodson and Horrell on their Laminitis Road Show series to educate horse owners on how to recognize and prevent laminitis.

A video of Knottenbelt's lecture on the equine foot (and what can go wrong) from that series can be viewed on The Hoof Blog.

Hoofcare & Lameness Presents World Horse Welfare's Laminitis Video Conference (Part 1)


Welcome to an amazing educational opportunity. World Horse Welfare and feed company Dodson and Horrell have created a series of videos from their recent "laminitis roadshow" conference in Great Britain and the Hoof Blog will be posting the videos here for you to watch at your leisure. This first brief video is the introduction and summary, featuring equine nutrition researcher Teresa Hollands of Dodson and Horrell.


In this first "feature-length" 24-minute video, you will meet Professor Derek Knottenbelt, who is no stranger to readers of Hoofcare and Lameness Journal. His article on pemphigus (sometimes called coronary band dystrophy and the subject of more articles to come) is one of the most popular articles ever published by Hoofcare and his work on hoof diseases is extraordinary in the way he integrates research and treatment with other areas of medicine.

Professor Knottenbelt was recently a guest speaker at Tufts University's Cummings School of Veterinary Medicine and I highly recommend him as a speaker. You'll see why when you watch this video, which includes one of his clever improvisational dramatizations--he becomes the hoof's laminar bond!  His simple explanation takes the mystery out of insulin resistance and how it is involved in the mechanical collapse of the foot in laminitis; this video also helps with explaining many other key concepts of laminitis and its prevention for horse owners.

More videos from the road show conference will be added to the blog in the next few days. Please watch them all, share them all, and refer back to them.

Many thanks to World Horse Welfare and Dodson and Horrell for their leadership in laminitis education for horse owners. This is critical information that needs to circle the world, wherever horses can be cared for in a way that helps prevent laminitis. It is, after all, a preventable condition in most cases and so much pain and suffering could be spared if horse owners can be educated about management practices.

Hoofcare@WEG: What's Inside the French Farrier's Tool Bag?

Click on an arrow to start the slide show. You should also be able to navigate to the images' pages on Flickr.com to see them in a larger size.

It all started early in the evening. I guess it was meant to be French night. I strolled through the Normandy pavilion here at the 2010 Alltech FEI World Equestrian Games. Inside was a poster showing a shoe being forged on the face of an anvil. It was promoting the 2014 World Equestrian Games, which will be held in Normandy. It was just a nice photo until I looked closely at the shoe in the picture and saw how the toe had been creased.

It seems like a good omen that the 2014 Games would include a horseshoe image in their promotion. I was happy as I headed to the show jumping arena. And then I saw him.

He slipped through the barrier without making a disturbance but something made me look over at him. Hundreds of people were walking by. But only one carried a beautiful leather bag over this shoulder. The very same type of leather bag I'd seen used by farriers in France. Made of saddle leather with a long shoulder strap, these bags bounce on French farriers' hips as they walk. You wouldn't fill one with sandwiches or Lego pieces: this is a special bag, a part of a farrier's life.

 I set off after him. 

I had heard that France had sent a farrier, but he had been eluding me for two weeks. I couldn't let him get away.

I felt like a wide receiver on a football team. I zigged and zagged through the warmup arena. Took a left at Sapphire, circled the $8 million Saudi horse, zipped behind a couple of Brazilians. I could still see him up ahead. He was headed to the top warmup ring, tool bag bouncing along through the crowd.

When I caught up with him, I was out breath. And that's when I learned that he spoke no English so I had to interview him in French, which means that none of the information in this article may be what he meant to say. But he was very nice about everything.

David Le Corre lives near Toulouse in France and is his country's sole farrier at the 2010 Alltech FEI World Equestrian Games. He has been busy these weeks in America, and tomorrow will be hard at work with all the farriers out on the marathon course. He dutifully posed with one of the French team horses and showed me its left front foot, which was shod with a plastic plad and a frog cutout, for what little frog the horse had.

And that is when things started to fall apart. I asked David about his tool bag, could I take a photo of it?

He obviously thought that I was asking if I could see what was in it, which I would never ask. I realize that the contents of a tool bag like that are personal, like the contents of a woman's purse. But in a split second, the beautiful leather flap was thrown open and shoes were spilling out onto the ground.

Shoes were taped together and clearly marked "droit" and "gauche" (left and right). Nearly every shoe in the bag had a pad attached to it. There were Luwex plastic mesh pads, full leather pads, leather rim pads, and impression material.

David obviously likes two things: leather pads and aluminum shoes. He even likes the two together. In the photo of the single rolled wide-web aluminum shoe, you can see what the studs will go. He has it set up with a leather pad, and if you look closely you can see where it has been scored for the frog to be cut out. The circles marked on the pad on either side of the frog will be punched out so that silicon or some other  support material can be injected under the pad, while the frog stays open to the air and able to touch the ground and be functional, with luck.

I sheepishly helped David put all the shoes back in the bag and thanked him. He settled down to check rider Penelope LePrevost's horse's feet and adjusted the big black band over the heel bulbs.

Like all the farriers here, he had a lot of work to do. The groom chatted happily to him in French. I imagined she was saying, "David, that woman chased you across three warmup arenas, who IS that?" and David answered, "I have no idea."

Note: Be sure to read the comment about David, which is a blog story in itself, in which David's effort to glue a shoe on one of the French team horses is aided and abetted by Alan Orville Dryg, one of the AFA farriers! Just click on the comment link. Alan had a French farrier tool bag experience too!

Hoofcare@WEG Video: Inside the On-Site Veterinary Hospital



You can also view this video at this link, if it is not showing up here.

Note: Blog visitors may or may not see a video in this space. The video is provided by WKYT in Lexington, Kentucky and shows the temporary veterinary hospital built on the grounds of the Kentucky Horse Park for use during the World Equestrian Games.

Horses with serious injuries or illness have been transferred to Rood and Riddle Equine Hospital, which is only six miles away. Some eventing and endurance horses have been treated there but, as the video says, the injuries have been relatively minor and few in number so far. That's something to be thankful for!

The on-site hospital includes a veterinary podiatry unit provided by Rood and Riddle Equine Hospital in the form of a Stonewell Forge equine podiatry rig. (I learned last week from Brent Chidsey at Stonewell that this truck is not the same as a farrier truck, no matter how much it may look like one.) Dr Raul Bras DVM of Rood and Riddle, who is also a certified journeyman farrier with the American Farrier's Association has been on site several times. He speaks Spanish and has been able to assist some of the South American teams, who also found their way downtown to the Breeders Supply farrier store.

A special guest at the hospital was Professor Jean-Marie Denoix of France, who provided diagnostic ultrasound expertise at the hospital and spoke at the veterinary conference that preceded WEG.

All my knowledge of the hospital is secondhand, since security there is very tight and they won't allow media (that's me) in, hence the posting of this video, which may be as close as I ever get!

Racehorse Performance "Not Significantly Affected by Tendon Injury", According to Horse Trust Research

This horse has "bowed" it superficial digital flexor tendon; the tendon protrudes, or bows out, at the back of the leg. This is the most common debilitating tendon injury suffered by racehorses and requires a long layoff for recovery, although new treatments are shortening the time lost from training. (Photo: Dr. Barak Amram/VetMoves)
Data compiled and analyzed in a research project in Great Britain funded by The Horse Trust found that racehorses who recovered from tendon injuries did not have inferior racing performance records compared to horses that had not had tendon injuries.

The research was led by Bryan O'Meara, who is in the final year of a three year clinical training scholarship funded by The Horse Trust. O'Meara carried out the research at Donnington Grove Veterinary Surgery in Newbury, under the supervision of epidemiologist Dr Tim Parkin from University of Glasgow.

Tendonitis is one of the most common musculoskeletal injuries in racehorses, with a prevalence of 11-30%, according to earlier research.

O'Meara examined the clinical records and racing histories of 400 racehorses who had been treated for superficial digital flexor (SDF) tendonitis injuries over a five year period from 2003 to 2008.

The race records of horses affected by tendon injury were compared with 400 matched control horses that had never suffered SDF tendon injuries. The controls were horses training in the same establishment at the time of injury and of the same age and sex as the case horse.

The Horse Trust-funded research looked at the performance of the racehorses in races before and after treatment for the injury, and at the performance of the control horses before and after the treatment date. The Racing Post Rating (RPR), which is published by the Racing Post (a British racing newspaper with charts) after every race, was used as a measure of performance.

O'Meara found that there was no significant difference in RPR before and after the treatment date in case and control horses.

This result is unexpected as in vitro studies have found that healed tendon tissue has reduced elasticity properties due to the presence of scar tissue. This suggests that a horse with a healed SDF tendon would need to work its muscles harder to compensate and would therefore be expected to have lower performance.

O'Meara said more research is needed to back-up his finding that performance isn't significantly affected by tendon injury.

"It could be that using Racing Post Rating to measure performance isn't sensitive enough to pick up a change in the horse's performance," said O'Meara. "However, it's encouraging that there's no marked change in performance after a horse has recovered from a tendon injury. These findings show that there's no need to give up on a horse that has a tendon injury--they can still come back and perform well, or can be used for other, less demanding riding activities."

The Horse Trust-funded research also found that there was no significant difference between case and control horses when returning to racing and completing three races. Only after completing five races, or three years post treatment, was a significant difference found between case and control horses. This finding is a step towards developing a more accurate assessment of tendon-treatment outcome after five races or three years post-treatment is a better indicator of the outcome of treatment.

"At the moment, some tendon treatments state their success as the percentage of horses that return to racing after treatment. However, we've shown that there's no significant difference between case and control horses at this time," said O'Meara. "At the moment, there are a myriad of treatments available to treat tendonitis. Hopefully this finding will be used in further research to learn which treatments are most effective."

O'Meara's research also found a link between SDF tendon injury and the racehorse competing at its maximum performance level: the case horses were significantly nearer to their pre-injury maximum performance level in the race immediately before injury (compared to matched controls), suggesting that they were competing nearer their individual maximum performance level when the SDF tendon injury occurred. (Note: this statement is not explained but would seem to suggest that either the level/class of the race or the distance perhaps was the best the horse had done in its career when the injury occurred.)

Editor's note: Information in this article was provided by The Horse Trust, a British charity that funds equine research and promotes education about horse health and welfare. Hoofcare Publishing likes to support The Horse Trust whenever possible. The research described in this article was published in the May 2010 edition of the Equine Veterinary Journal and is available online as a downloadable PDF file: "An investigation of the relationship between race performance and superficial digital flexor tendonitis in the Thoroughbred racehorse".

Readers should keep in mind that the study included only British racehorses and that the majority of British racing is done on grass. Race distances, conditioning schedules and training methods also vary in Great Britain from methods used in North America and some other countries. But the results are interesting, no matter where you live!
