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.

Dubai Horse Hooves Are Being Molded, Not Shod, with Experimental Hoof Application Process

by Fran Jurga | 12 September 2009 | Fran Jurga's Hoof Blog

Take a really close look at this "shoe". What looks at first glance like a Natural Balance shoe is actually a urethane hoof application created on the foot by injecting Vettec Adhere material into a mold. Vettec Superfast is sometimes also used, but Derek said that in this particular shoe, Adhere made the shoe more flexible.

Here's the ground surface of a six-degree short-heart bar, made for a horse with a fractured navicular bone.

A new shoeing technique developed in Dubai by South African farrier Derek Poupard is offered for your comments. In addition to the photos above, we have a short video showing how the mold is applied and the material is inserted, and the removal of the model to reveal a "shoe", if you want to call it that.



"This is so new, I only put my first one on 4 months ago, and after doing hundreds I now feel it is time to expose it," Derek wrote in an email. "I have only shown it to a handful of farriers here and right from the word go they embraced it and it is very rewarding to see their response as they peel of a mold seeing the perfect shoe. They all describe it as a revelation and every time they use it, it gives them the same feeling over and over again."

This has been a big year for plastic and composite horseshoes. First Curlin won the great classics of his four-year-old career last fall wearing square-toed Polyflex shoes of polyurethane. Then Steffen Peters and Ravel won the World Cup of dressage wearing plastic Eponashoes. This week, the venerable Horse and Hound news magazine from London carries a feature article touting the popularity of plastic shoes, especially those designed by our friend, the clever Andrew Poynton, who has expanded his moldable Imprint therapeutic plastic heartbars into sporty new models for competition horses.

And now we have the possibility of design-it-yourself hoof molds to make not shoes, exactly, but something else, a hybrid lighter and perhaps more cohesive with the foot than a separate shoe attached by nails would be. While steel and nails have their advantages too, this new technique may find a niche of its own, or become a platform for inventors or farriers and veterinarians faced with challenging hoof injuries or deformities.

This second video was made a while ago by a Dubai television station that visited the royal stables where Derek works. It's a nice view into the facility and shows Derek's previous traditional use of glue-on shoes on a Thoroughbred racehorse.



Eventually, Derek's molds will be available for sale, I'm sure, but in the meantime, the floor is open for comments. He's a world away from almost all of us and would like to hear from you, I'm sure.

Much more information is available at www.quixshoe.com.

Some American readers may remember Derek from his time spent living and shoeing in Virginia. He has been featured in Hoofcare and Lameness Journal in the past but when he left the USA several years ago, we lost track of him. A royal farrier shop in Dubai is an interesting place for him to be found.

New shoes continue to come on the market or be passed around as prototypes. This process is quite unique, though, and while it seems cumbersome and awkward at this stage, it is sure to improve and become more streamlined.

What could your imagination do with technology like this? What if...

Barefoot Racing in California? State Board Seeks More Time for Input, But Bans Heel Nerving and Steroids

A decision had been due in California last week about a proposed rule change that would allow Thoroughbred horses to race barefoot at the state’s tracks, all of which have recently been converted to artificial surfaces.

At yesterday’s meeting at Del Mar Racetrack near San Diego, the CHRB sent two the regulatory amendment back out for 15-day public notice with minor changes to the texts. The Board indicated it would suspend the portion of the rule that requires horses to be shod, as long as it is publicly noted in the official program. The memo from the CHRB indicated that a public hearing will be held.

Vice Chairman Richard Harris noted that while this proposal to allow horses to race unshod has been around for some time. He said that the installation of synthetic surfaces in California has helped push it forward because some horses appear to be training better without shoes on the new surfaces.

The amendment would allow a horse to race unshod if the trainer feels the horse might run better without shoes. Any changes would be noted on the official program.

According to the CHRB, the issue was first raised by the California Thoroughbred Trainers at a meeting of the CHRB Medication Committee last November. CTT Executive Director Ed Halpern indicated there had been sentiment among some trainers “for a long time to allow horses to race unshod, but with the introduction of synthetic tracks, the idea has gained support for moving forward. Some horses are more comfortable without shoes.”

Dr. Diane Isbell, one of the CHRB’s official veterinarians, provided some details during a special meeting on February 20 that focused on synthetic surfaces. Dr. Isbell was among seven veterinarians on a panel that discussed the safety of synthetic surfaces in terms of injuries to horses.

“We have much sounder horses (on the synthetic surface at Golden Gate Fields) and I’m finding that we have a lot less joint filling in the horses on pre-race (examinations) than we do when we have the sealed surfaces,” explained Dr. Isbell. She went on to say, “What we’ve found with the synthetic surfaces is the foot does not have the slip that it had with the dirt surface.”

Dr. Isbell continued, “A number of trainers in Northern California are starting to train their horses barefoot. There are an increasing number of trainers doing that (and those horses are) working as well or better as they did when they had shoes on. We do know from research work that the bare foot is better able to utilize the internal shock absorption system of the horse, which does help to take some of the stress off the legs.”

Dr. Isbell did not give a reference for that research.

If the regulation change passes, the official program will note when any horse adds or removes shoes. To date, the CHRB has heard no testimony in opposition to allowing horses to race unshod.

Written comments should be addressed to: Harold Coburn, Regulation Analyst, California Horse Racing Board, 1010 Hurley
Way, Suite 300. Sacramento, CA 95825.

For additional details, he can be reached at (916) 263- 6397 or Fax (916) 263-6022 or e-mail (harolda@chrb.ca.gov).

Most states and racing jurisdictions require horses to be shod. Kentucky Derby and Preakness winner Big Brown recently spent a few weeks barefoot while in light exercise at Aqueduct, but has since had glue-on shoes re-applied, according to hoof repair consultant Ian McKinlay.

Standardbred farrier Conny Svensson recalled in an article recently that he pulled the shoes on champion Moni Maker in 2000 when she she raced in France. She went out and trotted the fastest mile in European history. A few weeks later, the trainer gambled and tried it again when she was racing in Italy. She broke stride and was eliminated.

Artificial arena surfaces have been detrimental to the hooves of some unshod sport horses, although ill effects of racing surfaces have not been reported, perhaps because horses in most states are required to be shod. Farrier Bob Pethick in New Jersey documented the deterioration of hoof wall thickness in a barefoot warmblood when it was moved to a new stable with a more abrasive indoor arena surface. The case was documented in Hoofcare and Lameness Journal, issue #78. Click here to read the article online.

In other news, California added horsewoman and celebrity Bo Derek to the Board, banned the four major steroids from use on racehorses in the state, and unanimously adopted a regulatory amendment prohibiting posterior digital neurectomies, or “heel nerving.” Any horse that undergoes such a procedure after October 1, 2008, will be prohibited from racing. This prohibition was opposed by the Thoroughbred Owners of California, which believes California should wait for a national policy.
