Bisphosphonates Ban: Keeneland, Fasig-Tipton and Ocala Breeders’ Sales Ban Off-Label Use of Popular Navicular Disease Medication in Young Thoroughbreds

Bisphosphonates are a type of medication used to treat osteoporosis in humans. They have been approved by the US Food and Drug Administration since 2014 for treatment of navicular disease in horses older than four. Research in Europe, conducted by Professor Jean-Marie Denoix and others, has also investigated the possible expanded use of one bisphosphonate, tiludronate (Tildren) for other lameness problems, such as bone spavin and osteoarthritic lesions of the thoracolumbar vertebral column. Professor Denoix also led the initial research on Tildren for navicular disease in older horses.

Dual Surveys Compare Veterinarian and Horse Owner Priorities for Equine Research

Colic (gastrointestinal diseases) is considered by both equine veterinarians and horse owners as the most important equine health care problem in need of more answers, according to the results of parallel research surveys conducted by the American Association of Equine Practitioners (AAEP) Foundation and the American Horse Council (AHC) Foundation.

Women's History Month: Saluting nameless women farriers from the past

The oldest image in the Hoofcare and Lameness archives is this engraving from France. The title at the bottom translates roughly to: "To shoe the mule the people are usually intelligent." (Corrections are welcome.) Script at the top states that women understand that the mule responds to caresses more than to force. Image from the University of Texas library archives.

It's International Women's Day. The Internet is buzzing with salutes and tributes and memories of famous women and their contributions to history. While the Hoof Blog honors women today, as everyday, the archive has been opened so we can salute some anonymous women instead of famous ones.

Possible environmental chemical link found to equine metabolic syndrome and related laminitis in Welsh ponies and Morgan horses

Endocrine-disrupting chemicals (EDCs) in a horse’s environment may play a role in the development of equine metabolic syndrome (EMS), a leading cause of laminitis. This finding, made by Morris Animal Foundation-funded researchers at The University of Minnesota, could explain some of the variability in EMS severity that can’t be explained by other commonly measured factors, such as diet, exercise and season.

Laminitis Research Videos: Advances in endocrinopathic laminitis diagnosis, treatment and science

Last week,  31 laminitis research articles, collected from recent editions of the prestigious Equine Veterinary Journal, were made freely available to the public. All 31 articles may be read and downloaded without charge for the next year.

What could make this better? A summary--or three of them, in fact. Today we offer an overview of the research, in the form of three short, concise videos by three of the authors. Each provides an overview of the articles in his or her area of research.

Here are the details: 

100 Years Ago in Hoof Science: Quittor was the urban horse's biggest foot problem

HoofSearch, the index of equine hoof research, has been compiling a bibliography that documents the progress of hoof science on a year by year basis. What were the leading publications back in 1919, and who were the authors?

Laminitis Research: Is IGF-1 the missing link between insulin and laminitis in the horse's foot?

Veterinary researchers in Australia have identified a possible mechanistic link in the horse's foot that may explain how high levels of the hormone insulin cause equine laminitis.

British Horseracing Authority delays requirement of hind shoes on jump horses

Background: In the middle of the 2019 jump racing season in the United Kingdom, a major rule change that had been scheduled to take effect on February 1 is now postponed. The rule would have required all horses to race with shoes on all four feet. This follows a similar 2016 rule change in flat racing, that similarly required all horses in flat turf races to be shod on all feet, unless a declaration is made 48 hours before the race. Today the jump racing rule change was delayed. 

The information below was provided by the British Horseracing Authority.


Following the receipt of further submissions from the National Trainers Federation (NTF) and individual trainers, the British Horseracing Authority (BHA) has made the decision to delay the implementation of an approved rule which requires all jump racing horses to race fully shod. The rule was due to be introduced on February 1, 2019.

The delay is being implemented for a period of no less than six months, in order to allow for a number of actions to take place to further inform the debate on this matter.

The decision to introduce this rule was based on a two-year project which included evaluation of data and consultation with representative bodies including the NTF and Professional Jockeys Association (PJA).

The rule was intended to improve human and equine safety by reducing the chance of a racehorse slipping.

The rule had been agreed by the BHA Board and Rules Committee, and central to this decision were the facts influencing their rule change:

• Approximately 98% of all runners in Jump races in the UK already race fully shod;
• Data highlights that a horse racing partially shod in a jump race is over eight times more likely to slip than one that races fully shod. This equates to one slip for every 350 partially shod runners, compared with one in every 3,000 runners wearing four shoes;
• The introduction of similar requirements for flat racing has worked well and has been received positively;
• An exemption provision exists in the new rule to allow for a horse to race partially shod on legitimate veterinary grounds provided any application is supported by appropriate evidence;
• The PJA advocated introduction of the rule on the grounds of improved safety for horses and their members.

However, subsequent to the rule being communicated to trainers, the BHA has received new submissions from the NTF and individual trainers in which they raise concern about the rule’s implementation. In addition, a delegation of jump jockeys has submitted considerations on the matter, although the PJA remains in support of the rule.

As a result, the BHA has made the decision to evaluate these concerns in more detail before implementing the rule. This will include:

• Discussion at both the annual BHA Equine Welfare Agencies consultation meeting, and the BHA Veterinary Committee, specifically seeking views on the argument that wearing hind shoes increases the risk of tendon injury (particularly bearing in mind 98% of the NH population race fully shod);
• BHA Veterinary Officer Team to commence gathering data on tendon injuries suffered on a racecourse in a jump race that are the result of being struck into, in order to identify whether there is any correlation between the severity of the injury and wearing shoes behind or otherwise;
• Stewards will analyze any horse slip that occurs in a jump race and confirm the status of the horse in relation to shoes, and assess impact of the slip in the context of safety risk to jockeys;
• The NTF/Trainers who oppose the rule amendment are asked to provide any data or scientific evidence to support their view that there is a greater welfare risk to horses racing fully shod than partially.

Following the conclusion of this research, and consideration of further submissions, a final decision will be made around the implementation of this rule.

Laminitis Prevention: British Veterinarians Issue Alert to Prevent Spring Laminitis in Obese Horses

Links between equine obesity and laminitis are well documented, but veterinarians still report an increase in obesity; latest estimates are that as many as fifty percent of all horses in the United Kingdom may be overweight and at risk for related health problems. Today the British Equine Veterinary Association issued an official warning to owners that is valid all over the world.

The 33rd Annual Charles Heumphreus Memorial Lecture will take place February 16, 2019 at the University of California at Davis School of Veterinary Medicine. The event is a tribute to the vet school's longtime resident farrier, the late Charles Heumphreus.

New farrier/vet podiatry organization launched for US professionals

Texas farrier David Gilliam has a vision. The accomplished hunter/jumper farrier stopped talking about the way he thinks things should be and started doing something about it on December 6, when he launched a website for a new synergistic interprofessional association, Equine Soundness Professionals (ESP).

Saddle Research Trust Conference: Dyson research focuses on pain-associated behavior in ridden horses

"Horse, rider, saddlery interactions: Welfare and performance" was the theme of a landmark conference held this weekend in England.

FormaHoof Hoofcare Technology at the AAEP Convention: Is this hoof barefoot, shod...or protected?

FormaHoof is a new 3D hoof support process from Dubai. The hoof is not quite shod, and it's not exactly bare. Top farriers and equine podiatry veterinarians are singing FormaHoof's praises for not only the treatment capabilities of the molded coatings, but also the remarkable amount of sole growth and concavity they see at treatment's end. FormaHoof will be exhibiting at the American Association of Equine Practitioners Convention Trade Show, December 2-5 in San Francisco.

Whatever you call it, it has people talking. And looking. And asking questions. Until this week, FormaHoof seemed like just an interesting idea with a few slick videos on social media and a promise of results for rehabilitating hooves. “Liquid” horseshoes, some people called them. “Invisible” horseshoes, others said.

“3D” horseshoes?  We’ve heard that before, and can buy alternatives that claim the same effect, but for a lot less than the upfront investment in FormaHoof hoof treatment costs. Why, then, are farriers and veterinarians now buying and using the system?

Laminitis Survey Results: Do horse owners value science-based advice? Do they use it?

Equine research is fascinating, much-needed, and worthy of support. But are equine research findings being integrated into the care, feeding, and hoofcare of average horses? A survey in Great Britain set out to see if horse owners were applying research-based practices in their stable routines, using laminitis prevention as an example.

Palatable pergolide paste for PPID: BEVA award for Rendle presentation on clinical research into new treatment option for "equine cushings disease"

Many ponies and horses suffer from pituitary pars intermedia dysfunction (PPID), known in the past as equine cushings disease.  Among the common clinical signs of the endocrine-related condition, seen commonly in older (but not exclusively older) animals are long, non-shedding coats and chronic laminitis. PPID can, in most cases, be successfully managed by the medication pergolide mesylate, which is currently only FDA-approved in a poorly palatable tablet. A recent presentation on an alternative form of the medication has been recognized with a prize from the British Equine Veterinary Association.

Research into what may one day be a significant advance in options for the treatment of horses with pituitary pars intermedia dysfunction (PPID), once known as equine cushings disease, has received an award in the United Kingdom.

Vampire Bats: Why horses should be afraid of vampires--and not just on Halloween

Vampire bats in South and Central America love horse hooves. They frequently feed at the coronet, where the blood is close to the surface. Besides being creepy, vampire bats are the leading reservoir of rabies virus in Central and South America and have recently been identified as a host that easily spreads bartonella bacteria. Newly deforested landscapes are now home to domestic livestock; vampire bat populations have flourished with the captive animals so easily available to bite. Officials in Texas are now warning that common vampire bats have crossed the Rio Grande into the United States.

Until recently, most of us only thought about vampires once a year, on October 31. But that is about to change. While Count Dracula may be a figment of literary imagination, the real-life inspiration for his story is alive and well and spreading rapidly through recently deforested regions of South and Central America.

Horses, horseowners and horse professionals: Consider yourselves warned. Like the killer bees who paved the path, vampire bats may be headed your way. And they're bringing dangerous diseases with them.

Blacksmith Buddies: Vet school students and farriers work together in Florida

What is (or are) Blacksmith Buddies? A few years ago, University of Florida College of Veterinary Medicine students and local farriers joined forces for mutual education and camaraderie. It was such a success that it has gained momentum and now has an extended program of both informal ridealong opportunities for students and multiple educational events for both students and farriers during the school year.
