Favorite Video Clip: The Show-Off Jumper

Thanks to June Evers of Horse Hollow Press in New York for forwarding this clip of a young Belgian jump prospect. Assuming that this horse didn't break or rupture anything when he landed is testimony to the miraculous design of the equine limb.

The horse, whose name is Gesalme, is said to by Espom Gesmeray (you may remember him from the Athens Olympics in 2004) and is promoted by Béligneux-le-Haras.

Another Country Heard From: Hoof Project Research Center Grows in Texas

Dr. David Hood, director of The Hoof Project, at a recent seminar.

News from Texas is that the new Hoof Project Clinic and research center in Bryan, near College Station, is humming with activity. The clinic is open for the treatment of laminitic horses, and David Hood DVM, PhD is actively directing a team of researchers involved in 14 different studies related to laminitis.

Dr. Hood reports that 35 horses are in residence at the center, either in treatment or for use in studies, which include biomechanics, circulation, metabolism/nutrition, and laminitis pathology. Studies are particularly interested in the pain experienced by horses suffering from laminitis; Hood hopes to not just find ways to relieve the pain but also to determine the nature and source of the pain in order to prevent it.

His previous studies documented that horses with lamintiis suffer from secondary sources of pain. Changes in stance, posture, and gait affect tendons and ligaments in the legs, and joint angles may be altered, leading to arthritis. Even back and neck pain can develop in horses that are standing in abnormal positions for long periods of time. The fact that a horse has chronic laminitis may predispose it other co-existing lamenesses, such as ringbone, collateral ligament injuries, sheared heels, or navicular damage caused by long-term hoof capsule deformation and abnormally high heels.

Watch for announcements from The Hoof Project for the first series of seminars on hoof science to be held at the new facility.

UPenn Laminitis Research Project Hopes to Clarify the Mechanism of Developmental Laminitis

Dr. Hannah Galantino-Homer, senior research investigator of the newly created laminitis research initiative at the University of Pennsylvania School of Veterinary Medicine, is beginning her research in 2008 with a grant from Grayson Jockey Club Foundation.

“Molecular and Cellular Level Studies of Laminitis” is the title of the project.

Currently, laminitis still is so baffling to scientists that researchers tend to be split into two camps (theories) as to cause of the problem — vascular and enzymatic.

“The lack of agreement about the basic pathophysiology of laminitis explains why standard guidelines for therapy are not yet available,” noted Dr. Galantino-Homer in her research statement.

If this project can identify which specific genes and proteins are up-regulated or down-regulated during the first phase of the disease — when identifiable symptoms are not yet manifested — it “will determine the pathways of the disease and allow institution of preventive or interventional treatments sooner,” according to Galantino-Homer.

The first phase of laminitis, the developmental phase, is followed, of course, by the acute phase. One of the frustrations of dealing with the disease is that often by the time it is diagnosed, the horse may be gravely threatened.

Galantino-Homer believes the study “will provide information that we and other investigators can use to verify or elaborate on existing theories about laminitis, explore previously unrecognized cellular and molecular events during laminitis, and validate in vitro models of laminitis.” The latter will facilitate research projects that do not require laminitic horses.

"Lucky" Horseshoes in India Are Not So Lucky for the Horse

In India, shoes from black horses are considered lucky, meaning many horses are continually and carelessly re-shod by poor owners simply to feed the "lucky horseshoe" trade. Yes, it has to be a shoe from a black horse.

Vets from the international equine charity "The Brooke" (Brooke Hospital) in Delhi witnessed this in a black horse called Kalu, who was brought to them in pitiable condition. Kalu had overgrown, cracked and severely damaged hooves caused by years of re-shoeing (but not necessarily re-trimming) and was suffering chronic foot pain.

Brooke vets helped the horse and taught his owner, Bhoora, better shoeing skills, although he looks like he is pointing a very sharp object at Kalu's sole in this photo.

"Now Kalu is happy to be with me," says a grateful Bhoora.

Here's a link to a spiritual web site in India that will send you a horseshoe from a black horse in India for $6.95. They explain the legend, which is similar to the Western superstition about horseshoes. But they also claim that a horseshoe is good Feng Shui. A lot of Freisian and Percheron owners are doing the math...

The Brooke’s mobile vet teams and community animal health workers, and partner organizations worldwide provide free treatment to animals and train animal owners, local healers, farriers, saddlers, feed sellers, harness and cart makers. They currently operate across nine countries in Asia, Africa, Central America and the Middle East with over 750 highly-skilled staff working directly in the field.

The Brooke Hospital was organized in Cairo, Egypt in the 1930s to assist in the care of thousands of surviving American, Australian and British military horses that had been abandoned there at the end of World War I. Their reward for gallant service in war was a lifetime of hard labor on the streets of Cairo and as they aged, their health suffered terribly. However, the horses were so valuable to their owners' survival that the only humanitarian recourse was a campaign to improve their health. A first equine hospital was built...and the rest is history.
Please support the efforts of charitable organizations who put teams of professionals in the field and at disaster sites to help horses. Some day they might show up to help you.

The Evolution of the Horseshoe: Nail Holes of Antiquity

Would anyone care to comment on these 12th century horseshoes from the Museum of London? Yes, that's right: 12th century. That means these shoes were hammered out not long after the Battle of Hastings (1066) when the Normans beat the local Brits.

I have a terrific little booklet call "Old Horseshoes" by Ivan G. Sparkes, and it creates a timeline of horseshoe shapes and details, but it certainly doesn't have any nail holes like these shoes have, although he does reference wavy-rimmed shoes to the Saxon period of British history. (Horseshoes are mentioned in the Domesday Book of 1086.)

According to Sparkes, there is evidence that horseshoes were not deviced to protect horses' hooves, as is so often put forward. He claims that the nails were like keys, and were only nailed halfway into the hoof, in order to provide traction; the heel calks were built up to the same height as the protruding nail heads.

What you see in these nail holes is, of course, a spent hole that looks like it was made by a t-shaped punch, but an argument could be made for a t-shaped nail head wearing down into the soft iron of the shoe. If Sparkes' theory holds, the shoe would last much longer than the nails and go through a sequence of nails as they wore down.

If a modern design nail sat in that hole, you'd end up with a semi-fullered (creased) shoe. Various historical references quoted by Sparkes place the introduction of fullering in the mid-16th or 17th century.

The Circus Farrier

Check out this detail from an old photo for sale on eBay this week. It's from a collection of photos of the Ringling Brothers Barnum and Bailey Circus in the late 1930s or early 1940s. The credit is given to a photographer in Chicago.

The entire image includes a performer perched on the horse's back while he's being trimmed!
