Laminitis Prevention: Is Current Body Condition Scoring Irrelevant for Ponies?

by Fran Jurga | 18 September 2009 | Fran Jurga's Hoof Blog

A 9.2 hand, 12-year-old spotted pony named Firefly suffered from overgrown feet and laminitis in England in April 2007. She couldn't walk properly, but her owner refused to have her cared for, nor would she sign the pony over to the World Horse Welfare. A court case ensued and the owner lost her right to own horses for two years.

Here's Firefly in September 2007, on her way to full recovery and adoption to a new home. The research project funded by WHW at the University of Liverpool suggests that it is difficult to assign an objective body condition score to ponies using the system designed for larger horses.

Researchers at the department of clinical science at Britain's University of Liverpool, with support from the World Horse Welfare charity, presented new research at the annual convention of the British Equine Veterinary Association(BEVA) last week.

The question: how accurate is conventional equine body condition scoring for weight loss management when the equine being evaluated is an overweight pony?

The study, entitled Managed Weight Loss in Obese Ponies: Evaluating Weight Change, Health and Welfare, involved five mature, overweight or obese ponies and aimed to restrict their feed intake (on a dry matter basis) to 1% of body weight of a chaff-based complete diet for 12 weeks.

During this time the ponies' weight change, health parameters and behavior were monitored. All ponies remained healthy throughout the whole trial and an appropriate and safe rate of weight loss was achieved.

Clare Barfoot BSc (Hons) RNutr, registered nutritionist and the research and development manager for SPILLERS® (British horse feed company) explained: “Body weight decreased at a steady rate. However, despite significant weight loss, the body condition scores of the ponies didn't change. This highlights the concern that body condition scoring may not be the most effective way to monitor early weight loss in ponies.”

Even in this well-managed study, the feeding activity of the dieting ponies was decreased by 74 percent compared to ad libitum intake, highlighting the need for a practical feeding system that is both effective at managing weight loss but is sensitive to behavioral needs.

The WALTHAM® Equine Studies group was closely involved with this study as it has been with other groundbreaking work on equine obesity, such as showing that an obese body condition score was associated with increased insulin resistance back in 2003, and developing the cresty neck scoring system.

In response to the study, the research group is in the process of developing a new condition scoring system designed specifically for ponies. “This will involve validating the relationship between actual measurements of body fatness and the external appearance of the pony,” said Alex Dugdale, lead researcher for the study at Liverpool University.

Texas A&M Adds Full-Time Farrier to Hospital Staff

by Fran Jurga | 17 September 2009 | Fran Jurga's Hoof Blog

Jason Wilson-Maki is the first resident farrier at Texas A&M University College of Veterinary Medicine's Large Animal Hospital.

The following article is provided by Angela Clendenin of Texas A&M University. I don't think I know Jason Wilson-Maki, but wish him the best of luck in his new position and congratulate A&M for taking the important step of hiring a full-time farrier. Photographs were also provided by A&M.

COLLEGE STATION, TX –A certain specialization that is often overlooked or unknown by many people today is that of a farrier. A farrier’s job is to provide shoes for horses, and to work on their hoof problems. The Texas A&M College of Veterinary Medicine & Biomedical Sciences does a lot of work on lame horses, and a big part of treatment for horses’ hooves often requires therapeutic shoeing, and a specialist who knows what to do.

“For years, Texas A&M has had a farrier contract on an 'as needed' basis,” said Dr. Kent Carter, Professor of Equine Lameness and Chief of Medicine at the Texas A&M College of Veterinary Medicine Large Animal Hospital. “The problem with this type of contract is that we don’t always know when we are going to need a farrier and that makes us unable to provide full service to our clients.”

One year ago the faculty decided to do more towards pursuing a full time farrier to provide a better resource for our clients as well as a better teaching and learning environment for professional veterinary students.

“We set out on a national search for a full-time farrier and received a tremendous response,” said Carter. “There were 30 or 40 applicants who were narrowed down to 12, and finally we interviewed 5 of them. Jason Wilson-Maki had the most outstanding interview.”

A native of Ohio and a 1997 graduate of the Heartland Horseshoeing School, Jason was qualified for the job because of his previous experience and teaching. He also has a double certification in the American Farrier’s Association and the Farrier’s Guild (Guild of Professional Farriers). He showed great enthusiasm about horses and teaching during his interview and began work at the Texas A&M College of Veterinary Medicine during October of 2008.

Wilson-Maki feels that one of the greatest benefits of working as a farrier at a vet hospital, as opposed to being self-employed, is that working with so many veterinarians eliminates the guesswork, and is of greater benefit to the horses.

“Having a diagnosis and a prescription reduces the amount of trial and error required to improve an animal’s performance or soundness” said Wilson-Maki. “Moreover, the direct communication between the clinicians and myself benefits the animal by reducing the risk of a miscommunication. If I have any technical or application concerns, these issues can be discussed. This facilitates an individualized, comprehensive treatment for the animal which accomplishes the goals of the attending clinician and stays in step with the fundamental principles of sound farriery. This team approach is a great joy for me.”

Since such a huge part of an equine veterinarian’s career has to do with providing the physical skills needed to handle problematic hooves, Wilson-Maki’s expertise has taken the veterinary medical students’ education to the next level.

“It has been such an enjoyable experience interacting with the vet students,” said Wilson-Maki. “It is great to be able to see the light go on in their heads when applying certain aspects that they have been taught, but have not been able to apply until now. The students are constantly challenging me with questions that I must sometimes pause to think about the answer! Working at the CVM has truly been the best experience of my life.”

From enhancing veterinary medical education to providing value added service for clients, the farrier service at the veterinary medical teaching hospital has given the clinicians at the CVM another tool for helping their patients.

“Having a full-time farrier on staff has been extremely beneficial” said Carter. “We are able to provide a more consistent and thorough job for clients, as well as a better learning experience for students pursuing their veterinary degrees.”

The World Would Be a Better Place If There Were More of These

Farrier Vane, originally uploaded by Dave Angood.

Weathervanes, that is. They are one of the best ways to make a statement. A silhouette against the sky can be seen from afar and a good blacksmith can create a work of art to go atop a barn's cupola, a vet clinic, or a mobile home. Or a car dealership, clam shack or tipi.

It takes the observer's eye up to the sky and there's something uplifting about that, it more ways than one.

I just wish it wasn't so hard to get a good photo of a weathervane! It seems like there are always power lines or something in the way, or I can't get a good angle from the ground.

This is my new favorite weathervane, captured on film by Dave Angood, who tells me he found it atop an old barn inside some fortress-like gates near Swaffham in Norfolk, England. He allowed me to share it with Hoof Blog readers. I kept staring at it for the longest time this morning.

It reminds me of the beautiful weathervanes made by a farrier and heavy horse expert named Richard Gowing in England. If Richard didn't make it, surely his past work helped inspire it. Our friend the late Edward Martin from Scotland made beautiful weathervanes too.

Weathervanes carry some responsibility, of course. They have to be aligned with the earth. In our little seaside village, my salty old neighbor died and left a provision in his will that money from his estate be used to get steeplejacks to come and re-orient the weathervane on top of the church which, over the years, have drifted out of alignment.

It really bothered him. He saw the vane as a tool to check the wind as he drove toward the harbor each morning rather than the beautiful ornament on the church that the rest of us saw.

It's fixed now.

What--and where--is your favorite weathervane?

Thanks to Dave Angood for his hard work in getting such a good shot of this beautiful weathervane. Dave's trying to find out more about it and I'll add more details if he reports back.

Been There, Done That? Farrier Shrine to St Eloi Shoeing a Horse at Orsanmichele in Florence, Italy

Dr. Gaunt recognized a familiar scene when he looked up: anvils, hammers, and farriers at work. (Photo: Dr Geoff Gaunt)

British Columbia veterinarian Geoff Gaunt was strolling down the narrow streets of Florence, Italy on his summer vacation when he looked up...and smiled. He snapped a photo for the farriers back home, and I'm sharing it with you all, too.

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...

Rachel Alexandra: Preparing to Make History in Saturday's Woodward Stakes at Saratoga

Rachel Alexandra: Preparing to Make History in Tomorrow's Woodward Stakes, originally uploaded by Rock and Racehorses.

The go-go girl herself takes to the track at Saratoga on Saturday. Miracle filly Rachel Alexandra skipped the Travers Stakes for three-year-olds in order to challenge older males in the shorter mile-and-an-eighth Grade 1 Woodward Stakes.

Expect Saratoga to be the site of the biggest traffic jam in New York State since Woodstock. Really. Since the race is not televised, the only way to witness this historic event is to Be There.

My guess is that there's a pool somewhere on what the gate attendance will be. Perfect weather is forecast.

Will someone who has TVG or HRTV or OTB call me and hold the phone so I can hear Tom Durkin call the race? I'd like to hear history firsthand, even if I can't see it.

Ace photographer Sarah K. Andrew of Rock and Racehorses just uploaded this nice shot of Rachel leaning into her bath sponge so I thought I would share it with you all. Thanks, Sarah, for the perfect timing and the beautiful photo.

Win or lose, Rachel Alexandra has made this an exciting summer. Right about now, she's camped out in the detention barn so she knows something is up. What is up is that New York and the nation has fallen in love with this horse and what they think she can do, who they think she is, and the time is just exactly right.

I don't know if this will be her last race or not but with each and every race, work, and schooling session she went through at Saratoga, I marveled that she's been my good news story of the year. And I want her to stay that way.

Safe home, filly.
