Friends at Work: Victor Harbor, South Australia

Here's Budd Glazbrook shoeing one of the tram Clydesdales out in the courtyard in the seaside town of Victor Harbor, South Australia. His work day is also a public demonstration of farrier skills. The Clydes pull tram cars over a wooden causeway to a nearby island and have been doing it every day in the old whaling port since the 1890s. The tram runs year round and is one of the last in the world. Budd has 14 Clydesdales to shoe. Photo from the Victor Harbor Times.

Night Owls and Tivo-ers: Catch Vet-Stem on ABC's Nightline Tonight

Southern California's Vet Stem corporation will be the star of the show tonight on ABC News' Nightline news program, which will air a special segment on stem cell treatments for joint disease and arthritis in dogs.

While the show focuses on dogs, Vet Stem claims to have been involved in the treatment of more than 2000 cases of lameness in horses. Suspensory ligament injuries are the highest success rate for Vet Stem treatment, according to the equine portion of their web site.

The web site, by the way, has case studies of 20 or so different horses. You can download the documents as PDF files from this page. Scroll down to almost the bottom to read a case study on stem cell repair of coffin joint lameness in a four-year-old Quarter horse.

On the news page, there is also a video about the sprinter Greg's Gold at California's Del Mar racetrack who was treated with Vet Stem technology, which consists of extracting stem cells from fat deposits near the horse's tail head, culturing them so they multiply, and injecting them at the injury site. (That is a massive over-simplification!)

On the east coast, Nightline airs at 11:30 p.m.

Santa Anita: Los Angeles All-Weather Race Surface Prefers Nice Weather

Rainy weather has closed down lovely Santa Anita Racecourse outside Los Angeles, California since Saturday; the track will re-open today, Thursday. Santa Anita received approximately seven and a half inches of rain in 72 hours over the weekend. In spite of sealing the track before the rain and not allowing training on the main track, the new artificial racing surface is not draining properly. The surface has been plagued with drainage problems.

Jockey Mike Smith, quoted in the Los Angeles Times, said an inconsistent track can result in injuries to a horse. "A horse's hoof is sinking about one inch into the surface at one point, then suddenly the hoof is sinking in four inches," he said.

Rumors abound that the rest of the meet will be moved or that the track itself may be excavated. A major announcement is expected on Thursday.

The California tracks received a statewide mandate to switch to artificial surfaces for Thoroughbred racing. The same surface, Cushion Track, was installed at Hollywood Park and Santa Anita, but the Santa Anita surface has problems with the drainage pipes beneath the surface. The entire surface was dug up over Christmas in an attempt to fix the problem. Several major stakes races are scheduled for this weekend at Santa Anita.

Conference on Walking Horses and Horse Protection Act Planned for Ohio in April

"The End of Soring" is the goal of the first Sound Horse Conference to be held in Columbus, Ohio, later this year.

The event is set for April 11-12 at the Hilton Garden Inn and is sponsored by the Tennessee Walking Horse Breeders and Exhibitors Association, the American Association of Equine Practitioners, the American Horse Protection Association, Friends of Sound Horses and the Humane Society of the United States.

Described as two days of "stimulating conversation and action," the goal of the conference is to accelerate progress to end soring "by bringing all interested people together to share ideas, increase knowledge, resources and action plans."

Discussion will include the challenges to enforcement of the Horse Protection Act, technology for future enforcement, proposed research that is needed, detection of pressure shoeing, how to prevent soring and other related topics.

The Equine Affaire, an all-breed, all-sport horse expo, will also take place in Columbus during that week.

"Soring" refers to illegal methods used to exaggerate a Tennessee Walking Horse's natural high-stepping gait in the show ring. Under federal law, horses may be inspected for signs of soring prior to competition, and are disqualified if they are found to have been sored.

Disputes between trainers and federal officials over the inspection process plagued the industry during 2006, resulting in the cancellation of the World Grand Championship class at the Walking Horse Celebration, but the 2007 horse show season appeared to go much more smoothly

Traction Counts at the Rose Parade (Just Ask Ada)

In 1932, movie star Mary Pickford rode in the parade.

It wouldn’t be New Year’s Day without Pasadena, California's Rose Parade, America’s most extravagant (and fragrant) parade. It’s mostly about flowers—every float in the parade is made out of flowers, but it's about horses, too. Hundreds of them!

Draft horses pull floats. Four matched chestnut Quarter horses pull a Wells Fargo stagecoach. Mounted posses. Painted Indian ponies. And, this year, even some of the US Equestrian Team riders hopped on borrowed horses and joined in the parade.

What do all those horses have in common? At sometime during the night last night, each and every horse was visited by a woman with a flashlight and a clipboard.

For the seventh year in a row, Pasadena resident (and farrier) Ada Gates Patton was up way before dawn and marched through a half-mile long string of vans and horse trailers and picked up the left front foot of each and every horse. (Ada is an icon of American farriery and was the first woman licensed to shoe horses on a racetrack in America.)

This morning, Ada was looking to see what was on the bottom of the horses’ feet. The parade route is five miles (not counting the staging area) and a horse slipping on the pavement or worse yet, falling, is not something that would enhance the image of the parade.

So, Ada checks that each horse is either a) barefoot or b) shod with either Borium or Drilltek hardfacing or c) nailed with Duratrack “hard head” nails. Plastic shoes are also an option. I asked her if hoof boots were allowed; she said they are not on her list.

Here’s Ada’s report:

1. No increase in barefoot horses this year. As usual, the minis, the Peruvian Pasos, and the Bashkir Curlies were barefoot.
2. The Marines used Borium on the shoes of the Palominos in their color guard that led the parade.
3. No Drilltek was seen by Ada who then quipped, “Well, it was pitch dark out there and it’s hard to tell in the dark if it’s Borium or Drilltek.”
4. Draft horses tended to wear rubber shoes, like you’d see on city carriage horses.

“The biggest increase is the move toward Duratrack nails,” Ada said. “I’ve been pushing them in that direction. I was surprised to see that some used as many as six Duratracks in one shoe. It's a no-brainer. The Duratracks (nail heads) are good for about five miles on pavement, which is the length of the parade.”

Ada said that no horses slipped and there were no mishaps, as far as she knew, and there haven't been any since she has been inspecting the horses for the Parade committee.

Ada said that she had full compliance today from the horsemen. No one needed to have their horses re-shod. She mentioned that one group of silver-saddled Palominos from Long Beach brings two farriers "just in case" but there was no official farrier on hand. There were, however, three veterinarians and a humane society horse ambulance standing by.

Looking Back at 2007: This About Sums It Up, or: Israeli Vet Reminds Us Why We Are Still Just Spinning Our Wheels in Hoof Research

{Syndicated content copyright 2008 Fran Jurga's Hoof Blog and www.hoofcare.com}

"Incorporation of more advanced analysis systems in recent years has provided veterinarians with abundant new information related to the various effects of common shoeing and farriery techniques on foot and lower limb biomechanics. It is quite obvious however, that some aspects are still controversial or unclear. Among these controversies are the effects of change in heel height on the angles of the PIP ("pastern") and MCP ("fetlock") joints and on the strains of the flexor tendons and SL ("suspensory ligament").

"Comparisons of unshod and shod horses are rare, but the use of analysis systems, such as the pressure mat, may help to clarify debate about the purported benefits of shoeing horses versus leaving them barefoot. Fine (finite element) analysis of the distal limb seems to be limited by the complex anatomy. Indeed, it seems that a full understanding of the function of smaller structures, such as the distal sesamoidean or collateral ligaments, may only be achieved with the use of computer simulation.

"Finally, it should be noted that from an evidence-based perspective, most studies that have been performed evaluating the biomechanical effects of the common shoeing and farriery techniques have been performed using sound horses, and many others have been in vitro studies. Thus, although the information obtained from such studies is interesting, its direct clinical relevance is speculative and the strength of evidence is not as strong as is desirable. "

--from the summary of the paper "An Evidence-Based Assessment of the Biomechanical Effects of the Common Shoeing and Farriery Techniques" by Ehud Eliashar, BSc, DVM, MRCVS, published in Veterinary Clinics of North America: Equine Practice, in August 2007.

Translation: when it comes to hoof research, "evidence-based" is a relative term. The same sentiment was voiced at the Fourth International Equine Conference on Laminitis and Diseases of the Foot by Rustin Moore DVM PhD DACVS in his lecture "Evidence-Based Treatment for Laminitis".

For years, many respected voices have called for a standardizd protocol for foot research. We are expected to accept as gospel studies performed on treadmills. Bar shoes or wedges tacked on to only one front foot. Horseshoes nailed onto untrimmed, unbalanced feet. Shoes tested on ponies instead of horses. Raceplates on high-heeled non-racehorses. Shoes applied for testing without following manufacturer recommendations. And, in almost all studies, the lack of control data of the horse without shoes, or at least with normal flat shoes. Contrary data even exists as to whether horseshoes dampen or increase concussion.

Dr. Eliashar's paper points out changes in study results on the same condition when the horse is on a treadmill and controversies over interpretation of statistics on toe grab relevance in racetrack breakdowns.

Looking ahead, it makes sense to draw parallels between the struggles between Darwinism and creationism when comparing the arguments for the benefits of shoes vs natural (shoeless) trimming. When scientists like Eliashar and Moore are cautious about labeling existing scientific data as "evidence-based", the boat has some serious leaks.

For years, researchers like Chris Pollitt have asked, "How do you expect us to explain laminitis when we don't know how the normal foot metabolizes and grows and functions?" Researchers like Robert Bowker have mused, "I discovered this really interesting facet, but I don't know what it might mean..."

Kudos to those willing to admit that the function of the foot of the domesticated horse is still a mystery and that science doesn't have all the answers. Science may not have even been asking the right questions.

Happy new year, anyway!
