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!

American Farrier Associations Elections Near

Maybe it's my proximity to New Hampshire and all the US Presidential election publicity here, but I've taken a keen interest in the American Farrier's Associations elections this year and have compiled some of the minutiae about the candidates.

A new system of government goes in place in February when New York farrier Andrew Elsbree takes office as president over a smaller board of regional directors instead of representatives of individual chapter associations of farriers.

Two former AFA presidents, Bruce Daniels of New Jersey and Walt Taylor of New Mexico, are candidates for the new board. In fact, most of the candidates are former officers, committee chairs, or chapter presidents.

Commercial interests are heavy in the elections; two candidates are technical reps for manufacturers and another has his own line of tools. At least three of the candidates are (or at least have been) commercial clinicians for a horseshoe distributor. What's oddly missing is the competition constituency, although Jason Harmeson was recently on the American Farriers Team and several candidates mentioned their competition experience as helpful to their professional development.

Of the 28 candidates, 21 hold the AFA's journeyman certification and only one is not certified.

AFA elections are always interesting. In the candidate statements, each candidate provided a photo. Three posed with horses. Two posed with their dogs. Seven sent in photos of themselves in a work setting or anvil-side pose. Two donned neckties. Nine chose to be photographed wearing ball caps; two preferred stetsons. One was excluded from the montage of candidates on the front cover of the election guide. The only two bearded candidates are from New England.

One thing they all have in common: they are all men. And they all want the job.

Quarter Horse Web Horseshoe Poll, Certification Article Published

The American Quarter Horse Association (AQHA) has been working with the American Farrier's Association (AFA) lately; the two organizations have an educational partnership exchange.

To that end, the December issue of America's Horse, the AQHA's promotional magazine, has an article about the conduct of an AFA Certification Testing Day in Oklahoma earlier this year.

I highly recommend that anyone who reads this blog find a copy of that magazine (it's not posted online, I checked) and read it. Pay particular attention to the last page, which shows a finished shod foot as presented to the examiner, who then reviews the clinches and explains what is wrong or right with each.

If you know anything about nailing horseshoes, it's interesting to see if you saw what the examiner saw.

My guess is that the nailing shown, imperfect though it may have looked to the examiner's eyes, is of a higher standard than most readers of that magazine would normally see. They might miss the whole point.

What I did find on the AQHA site was a poll of site visitors on the types of shoes their horses wear.

Barefoot was given as a choice, of course, but with the comment "barefoot is better" embedded in the survey question; roughly one-third of the site visitors agreed and said their horses were not shod. If that percentage is indicative of Quarter horse owners in America, then one-third will really disconnect from the AFA's nailing critique in the magazine.

More interesting, though, is that the AQHA listed Natural Balance as a separate category of shoes (bar/therapeutic? normal? sliders? Natural Balance?) To me, Natural Balance is a "normal" shoe.

I wonder how many owners are truly conscious that their horses wear Natural Balance shoes. Apparently five percent of the total is savvy to their brand name shoes, but the actual total might be higher. There are also Natural Balance lookalike shoes sold, and regular shoes can be re-shaped that way. And just to confuse matters, a horse could be shod with sliders made by Natural Balance or therapeutic shoes based on the Natural Balance pattern, as well!

Hoof boots were not listed as a choice. I've just heard about a sliding plate hoof boot that is coming to market; that should be interesting!

The poll is ongoing; check it out here. Results showed that only roughly 52 percent of the total horses were shod with normal shoes; 32 percent were barefoot, 5 percent wore Natural Balance, 7 percent had sliding plates, and 4 percent wore therapeutic or bar shoes.

Thanks to the AQHA for the educational initiative. It's a jungle out here, isn't it?

GAIT ANALYSIS: Western Pleasure Show Classes Under Scrutiny for Gait Anomalies

A meeting in Dallas in September, jointly hosted by American Quarter Horse Association (AQHA) and National Snaffle Bit Association (NSBA), invited the top 100 riders from NSBA, the top 10 riders from open Western Pleasure at AQHA’s World Championship Show from the past three years and a team of judges who specialize in western pleasure.

They took the classes apart and looked at the equitation, the judging rules and especially the gaits and movement and speed of the horses in the ring. A special sub-committee is now working on a video to educate the entire industry on the specifics of Western Pleasure horse movement.

Some of the points to be covered in the video include:

• Placing more emphasis on judging the walk and using the video to educate exhibitors on improving the walk.
• Finding a balance for the amount of time spent judging the jog and the moderate extension of the jog.
• Addressing the head-bob at the lope, why it occurs and ways to avoid or correct it. This included educating exhibitors on lengthening their horse’s stride versus shorter, manmade strides; addressing the importance of conformation and what movements certain horses are physically capable of; and reassuring exhibitors that it is OK to show off the rail and that passing another horse can give exhibitors an opportunity to demonstrate their horsemanship, and show their horse’s ability to guide while maintaining an even cadence and consistent performance
• Educating rank-in-file members and beginning western pleasure competitors on the positive and negative characteristics of western pleasure horses, and on how the discipline continues to improve.
• Additional education for judges and continuing to push for and establish industry standards.
• Varying the gait calls to make it more interesting for horses, exhibitors and spectators.

As far as I know, this is the first time that the head-bobbing lope has been mentioned by Western Pleasure officials. What they describe as "manmade gaits" will confuse readers who are not familiar with this type of showing. How a horse can win a blue ribbon for a head-bobbing lope is something that takes a bit of getting used to, and video will be the best way to get the message across, surely.

For the uninitiated, this sport also has a unique training phenomenon called the "spur stop" or even rating the horse by leg pressure so that the reins don't have to be shortened.

(Sorry, I know that is not a very accurate description. The video should explain the logic behind the spur stop. The absolute perfect cadence of these horses is a script that must be followed and trainers have figured out how to achieve it. The result is that a moving horse need not cover much ground.)

Western pleasure survived the "peanut roller" controversy a decade or so ago and the classes only grew larger, so surely this latest revamp will also move things forward and improve the well-being of these horses.
