Grayson Laminitis Research Funding Breaks New Ground: Richardson, Pollitt and Van Eps Join Forces for International Support-Limb Laminitis Prevention Study
Laminitis research figured prominently in the mix of subjects to be studied. In particular, two studies will receive support from the Lexington, Kentucky-based charitable organization.
The first covers the dreadful form of laminitis that led to the death of 2006 Kentucky Derby winner Barbaro. This will be a multiple-year study; "first year" refers to the funding applied for 2011. Andrew van Eps received his PhD at the University of Queensland in Australia by studying laminitis; his previous contributions have included the first studies of the use of cryotherapy to prevent laminitis.
Here are the Grayson descriptions of the new studies:
| Laminar Energy Failure in Supporting-Limb Laminitis | |||||||||||||
| Dr. Andrew Van Eps, University of Queensland--First Year | |||||||||||||
This project is headed by a young researcher, but the co-investigators are world renowned Drs. Dean Richardson and Chris Pollitt.
The researchers will test the hypothesis with a state of the art, minimally invasive technique known as tissue mycrodialysis in conjunction with three dimensional computed tomography to develop effective methods of preventing or minimizing lamellar tissue energy failure. Comments in the Research Advisory Committee evaluations included “may well provide immediately applicable strategies to prevent supporting-limb laminitis” and “really nice grant, new idea about a devastating problem.” Dr. Richardson received second-year funding for his ongoing study of laminitis:
Another completely new study will begin at The Ohio State University, where the mechanism of cryotherapy in averting laminitis will be studied and, hopefully, recreated via pharmacology.

Equine Hoof Lameness, Laminitis Survey Results from British Study; Statistics Announced at National Equine Forum
 |
| Great Britain's Princess Royal addressed the National Equine Forum, where new statistics on horse health were presented. |
 |
| Josh Slater, Professor of Equine Clinical Studies at the Royal Veterinary College and immediate past president of the British Equine Veterinary Association (BEVA), announced the results of the survey, which was pioneered by The Blue Cross animal charity and is supported by BEVA. The survey was conducted in November 2010. |
The survey, which was pioneered by The Blue Cross animal charity and is supported by The British Equine Veterinary Association (BEVA), was carried out last November following two years of pilot schemes. The intention was to find out more about endemic non-notifiable equine diseases that have never before been recorded, such as coughs, skin diseases and lameness.
The results were announced at the Forum by Professor Josh Slater, Professor of Equine Clinical Studies at The Royal Veterinary College, who has been working with The Blue Cross on the survey. Analyzed data from the study will be used to pinpoint current, non-notifiable healthcare issues affecting horses, ponies, donkeys and mules in the UK and is expected to break new ground for all of Europe as well.
Professor Slater explained that the survey should provide a future benchmarking facility for equine disease, welfare, standards of care and codes of practice and it has also confirmed the workability of an important template to monitor the serious threat of infectious and exotic disease in the future.

Equine lameness statistics also figure prominently in the survey and show some variation from oft-quoted statistics about soundness problems in horses.
The results showed that lameness was the most common problem affecting horses (11% of horses surveyed) but that, unexpectedly, the foot was not the most common cause of lameness and that laminitis (3%) was less common than the 7-8% total that previous surveys had suggested.
Weight management was the next most common issue for horse owners, with 9% of horses recorded as overweight and 8% as underweight.
The new statistics are not far from those compiled in the study Equine laminitis in the new millennium: frequency, risk factors and assessing a potential new therapy by Claire E. Wylie et al, presented at the 2009 meeting of the Society for Veterinary Epidemiology and Preventive Medicine. Wylie found that laminitis cases contributes to between 0.11‐28.57% of all equine visits analyzed by veterinarians who participated in her study, with a mean of 5.03% and a median of 3%.
The most often quoted statistics from Britain are from Hinckley and Henderson's 1996 paper presented at the 35th Congress of the British Equine Veterinary Association. (See Hinckley, K.A. and Henderson, I.W. 1996. The epidemiology of equine laminitis in the UK in the 35th BEVA Annual Congress Proceedings) That paper stated: From a study involving 113,000 horses in the UK it was estimated that the total prevalence of acute laminitis in the UK was over 8,000 cases annually, giving a prevalence of 7.1%.
Anyone who reads this blog knows enough to see little red flags popping up right away: there is a big difference in a study like Hinckley's that tracks cases of acute laminitis with a study of all cases of laminitis, like the National Equine Health Survey's, as reported by horse owners.
 |

Another study that is often quoted found a much higher prevalence of laminitis in Great Britain around the same time. Katz surveyed the health of horses at a large charity farm with a population of 1140 horses and ponies, and found an average of 148 episodes of laminitis (prevalence of 13%) occurring each year (between 1997 and 1999), involving 113 animals. (See Katz L, DeBrauwere N, Elliott J, Marr C, Pfeiffer D. The prevalence of laminitis in one region of the UK in Proceedings of the 40th British Equine Veterinary Association Congress.)
None of these statistics really add up. I have often heard Katz's 13% quoted as the nationwide prevalence of laminitis in the UK, when he was actually studying a population of horses that might rightfully be expected to have some sort of laminitis, related to age or neglect circumstances that required their removal to a charity farm. Were those horses a suitable population to use as a sample of the entire national population of horses?
Hinckley's statistics have always been shocking, considering that she was documenting strictly acute cases. Wylie's study, presented as a poster at the conference, does not specify how laminitis was defined. Having her statistic closely matched by the much larger population sampled by the National Equine Health Survey's is encouraging, if their parameters were similar.
That said, a lot depends on when a survey is conducted. Some years have much higher numbers of cases because of weather conditions that encourage grass-related laminitis. The problem with this study's result is that it is tempting to say that education, medication and horse-owner awareness are kicking in and more horses are avoiding laminitis than in the past. But then we immediately see that 9% of the horse population is overweight, and can only wonder if that figure is up or down from previous periods. If that number is down as well, then all the hard work of vets, farriers, feed companies and charities is having an effect and horses in Great Britain are in a lot less pain now than they were 15 years ago. Maybe.
Here's a brief slide show summarizing the National Equine Health Survey in Great Britain (click on right to advance slides):
An interesting extrapolation from the study is that 18 percent of the horses had a problem with weight management (either under- or overweight) vs 11 percent who had suffered from lameness. It's possible that the actual weight problem is much higher, since the statistic allowed the owner to judge his or her own horses' weight suitability.
To clarify the location of lameness: it may sound like news that lameness in the foot was lower than expected, but it should be made clear that lameness location was divided into three groups: foot (3.7%), non-foot (4.5%), and laminitis (3%). If you consider laminitis a lameness of the foot, the combined total would be quite a bit higher than non-foot sources of lameness. However, for the purposes of the study, the statisticians were probably trying to keep their categories separate.
Meanwhile, the British Horse Society reports that its 2011 Laminitis Conference, planned for the end of this month in conjunction with Dodson and Horrells, has been sold out and no more registrations can be accepted.
It's so difficult to compare statistics from different studies or to say that one is the definitive measurement of the most pressing equine health issues. It sounds like the new National Equine Health Survey could be on its way to being the one-stop source for horse health statistics in Great Britain. While it's easy to wonder about the validity of horse owners' judgments about things like their horses' conditions, it's more productive to congratulate the Blue Cross and BEVA for undertaking such a massive effort, and for getting it done. And, most of all, for making the results available to the public. Thank you!

Arkansas Veterinary Practice Act Definitions Sought for Guiding Exclusion of Farriers, Tooth Floaters, Other Professions
Before you click "play" on the video, please take a minute to read this text so you will know what you are watching.
It's time for the politics of horsecare again. Or is it the politics of veterinary care?
We're back in Little Rock, Arkansas, and here are the gentlemen of the House Agriculture, Forestry & Natural Resources Permanent Subcommittee of Agriculture. They need to review all bills under their jurisdiction before they are presented to the legislature. We met them before, in late January, when they heard testimony on House Bill 1099 (video of that hearing is also posted). H.B. 1099 would have exempted a long list of animal care professionals from the all-encompassing but loosely defined description of veterinary medicine in the Arkansas Veterinary Practice Act. That bill was not voted forward by the committee.
So Representative Gary Smith came back again on March 9, with House Bill 1712. This bill was much more specific and only dealt with horsecare. In particular, 1712 would have exempted massage therapy, tooth floating, and farriery and hoofcare, although it would have created a state certification program for equine dental technicians.
The video you'll see in this video begins as the hearing for House Bill 1712. It, however, morphed into a presentation of a second bill; likewise, farriery and hoofcare morphed into "the lawful practice of horseshoeing". There is considerable discussion of what the lawful (or unlawful) practice of horseshoeing might be.
This is a very long discussion, but probably worth your time to have a listen. The second bill, known as House Bill 1763, was received more favorably and seems to be a compromise favored by the state veterinary board. Please note, however, that HB1763 is marked by the state government as "re-referred to committee" on the official state web site rather than approved. Reports in the press indicate that the bill was approved. This is a discrepancy.
For those who don't want to go through the video, the second bill went through an amendment process, in part to clarify the description of horseshoeing. The bill was amended to read: Arkansas Code § 17-101-307(b), concerning the practices that are excluded from the practice of veterinary medicine, is amended to read as follows: (b) This chapter shall not be construed to prohibit: (8) Any person: (A) Engaging in the art or profession of horseshoeing.
The meeting to amend HB 1763 was not videotaped, or the video is not available to the public.
If HB 1763 passes the legislature, it does not exempt massage therapy and tooth floating indefinitely; it only gives them a two-year moratorium from cease-and-desist orders from the veterinary board. After two years, some other bill should be waiting in the wings to take over, or these horse professionals may not be able to work in Arkansas.
Hopefully other states can learn from what is going on in these midwest states (Oklahoma and Texas are two other states with recent legislation) as they struggle with the interpretation of what veterinary medicine is, and isn't. According to the existing law in many states, veterinary medicine pretty much encompasses all care of animals. The time to have exempted professions was back when the draft veterinary practice act was introduced, but no one's ears were up then, or else no one ever thought that cease-and-desist letters would be sent out.
It seems pretty obvious that efforts to combine large and small animals or even cattle and horses, or to combine different professions makes it difficult for legislators and for people from agencies and businesses who would testify. It may be that it's every profession for itself. Arkansas has proven that quite clearly.
Another thing that seems obvious is that the legislators are looking for highly credible testimonies on these subjects. There's no question that they don't know much about the flow of services, or what happens when a horseowner needs some work done on a horse. Before this legislation came up, they probably never gave it a thought beyond the fact that they knew that veterinarians make barn calls. They're getting an education and they're learning that the horse industry in their state employs a lot of people on a lot of levels. And it takes a support crew of professionals of many descriptions to keep a stable of horses adequately prepared for showing, racing or even just recreational riding.
No one who is elected by public votes wants to put people out of work, yet the state government is in the business of enforcing the laws and legislation it has on its books. These legislators have to stand behind their government's previous actions. Change may be necessary, but it may also be incremental...and painstakingly slow.
If I lived in Arkansas and was working in any of these professions, I think I would slow the process down even further and ask for more amendment to HB 1763 by defining each of the professions the way that tooth floating is defined. If someone has a natural hoofcare practice and does not engage in horseshoeing per se, is he or she not exempt? Must a shoe be on the horse for this law to stick? Now's the time to find that out, not when a cease-and-desist letter arrives in the mail. And to get it printed in the bill, not in a verbal assurance.
Maybe you're one of the people affected by legislative rumblings in Arkansas or other states. Maybe you're hoping this will just go away. Be careful what your wish is: it will be back, if people care about preserving your profession. If no one cares, your profession may be lost in a legislative or legal shuffle one day, and your livelihood along with it.

Laminitis Prevention Research: Ponies Adapt to Grazing Time Reduction by Eating More in Less Time
Intake of large amounts of fructan and other rapidly fermentable carbohydrates by grazing ponies has been linked to the development of laminitis. As a result, it has become common practice for horse owners to follow advice from researchers, farriers, veterinarians and nutrition experts to restrict their ponies’ access to pasture, especially at key times of the day/year in order to reduce the risk.
The study, which was conducted at the Institute of Biological, Environmental and Rural Sciences (IBERS) at Aberystwyth University in Wales, in collaboration with the WALTHAM Equine Studies Group, aimed to investigate the effect of grazing restriction on herbage intake and grazing behavior in ponies.
The grazing behaviour of eight ponies was measured daily over a six-week period to assess their voluntary intake of herbage and to monitor the effects of restricting their access to pasture. Two groups of four pony mares were used. Group A had 24-hour access to pasture while the ponies in group B had three hours of pasture access per day and were stabled for the remaining 21 hours, with ad libitum access to haylage and water.
Herbage intake was estimated during the three hours when all the ponies were at pasture by monitoring the change in weight of each individual over the period. Grazing behaviour was analysed from video footage of the two groups using interval sampling. The ponies in group B had higher estimated grazed herbage intakes than those in group A during the three hours studied and this difference was significant during the final week, when they consumed 40% of their total daily dry matter intake as grass in the three hours at pasture. This compared with an intake of grass of around 25% of their daily dry matter ingested during the first week.
Clare Barfoot RNutr is the research and development manager at SPILLERS®, the British feed company. On learning of this research, she said: “This suggests that ponies with reduced access to pasture are capable of ingesting considerable amounts of grass during the time they are turned out and may indeed progressively increase their intake during this time, indicating that the behavior could be learned. The implication is that reducing ponies’ time out on normally managed pastures with the view to limiting the intake of rapidly fermentable carbohydrates may not be as effective as first thought.”

Theo Jansen's Anatomical Inspirations: Abstract Musing Can Help You Understand and Appreciate Hoof Design
Spring is in the air and a hoof blog editor's fancy turns to...kinetic sculpture.
But you'll soon understand why.
To anyone who says we can't improve on the way that horses are trimmed or shod, or the way that lame and sick horses' legs are treated or cared for, I'd have to say we're just not trying hard enough. And the answer is not likely to come from tinkering with the designs and devices we already have in our hands.
Kinetic sculptor Theo Jansen builds 'strandbeests' out of PVC pipe and turns them out on the wild ranges of the sand on Dutch beaches. The goal is for his perpetual motion creations to become permanent, independent citizens of the sands.
 |
| Jansen's kite-like sculptures will trot along the beach on PVC legs and coffin joints. |
You can't help but notice that his sculptures' legs and feet mimic the design of horse' limbs, right down to the single digit and breakover action of forward motion via a rotating distal joint.
 I |
| Maybe Jansen's been reading the Hoof Blog and saw this extreme rocker rehab on a foundered foot from Loic Entwistle's photo files in Germany. I'm sorry I don't have more information about this photo. I don't even know if this is Loic's work. But the image has always intrigued me. It's a thought-provoker. |
Think backwards for a minute. What if you could be Jensen and design a new hoof for the horse, one that would be easier to work on, to keep sound, to serve the horse on multiple surfaces, in multiple environments, under a rider's weights, in different sports?
What would your design parameters be for the lower limb and hoof? Where would you start--at the bottom? in the middle? Would you specify a model with replaceable (transplantable or implantable) parts?
There's no doubt that Nature designed an amazing structure that functions organically with perfection when everything's right. Humans just seem to muck it up, in one way or another. Bioengineering is on its way to being able to identify weak tissue structures; perhaps digital cushion implants will be possible soon, or coronary band grafting will allow rehab to be completed in six weeks instead of six months.
I suspect most of us would be happy to tinker with the parts to improve them, but we like the design just the way nature has given it to the horse, and to us to work on, to ponder, to study, to capitalize upon, or to admire.
Maybe we should invite Theo Jansen to watch our horses run on the racetrack. What we'd end up with in return might be a little different than what you''d see him sketch on a drawing board. Imagine a silky, kite-like kinetic sculpture floating around the infield of a dark racetrack at night, under its own perptual power, making eerie music like a chorus of call-to-the-post buglers playing a duet with every foghorn on the coast of Maine.
People would pay to see (and hear) something like that. I think they'd pay to see lots of things he does. Keep an eye on him, and his beests. I think he's trying to tell us something
