| For years, laminitis has been characterized as a disease of the horse's foot. Treatment has centered on relieving pain to the foot and facilitating healthy new growth. But just as important is understanding what caused the laminitis to occur and treating laminitis as a disease of the entire horse, not just the feet.

Equine Obesity Update: Do Horse Owners Comprehend the Dangers?
14 November 2009 Fran Jurga's Hoof Blog at Hoofcare.com
There's no doubt that the horseowning public in the United States and abroad is becoming more aware of the problem of obesity in horses. Just look at the variety of new feed products and supplements designed to help horses lose weight, and you will see just the first wave of a marketing tsunami aimed at assisting horse owners in reducing the weight of the horses.
The problem may not lie in just recognizing obesity, however. For many horse owners, telling them their horses are fat is akin to telling them that they have spoiled a child with candy. In their eyes, fat horse is a sign of a well-fed and much loved horse, but they may not connect the dots to the real health risks associated with obesity, such as insulin resistance and a high risk for laminitis.
In this video, the British international charity World Horse Welfare updates us on their progress in educating horse owners and also in surveying horse owners for their perceptions of obesity in horses. You'll also see a severely overweight pony that was confiscated by officials as a welfare case because of its obesity. This was the first prosecution of horse owners for welfare violations directly related to overfeeding a horse.
I love the last part, where the pony stands next to a pile of bags of feed equal to the weight he has lost.
Thanks in advance for sharing this video and keeping public awareness of the dangers of equine obesity at the forefront.

Laminitis Prevention: Is Current Body Condition Scoring Irrelevant for Ponies?
by Fran Jurga | 18 September 2009 | Fran Jurga's Hoof Blog
A 9.2 hand, 12-year-old spotted pony named Firefly suffered from overgrown feet and laminitis in England in April 2007. She couldn't walk properly, but her owner refused to have her cared for, nor would she sign the pony over to the World Horse Welfare. A court case ensued and the owner lost her right to own horses for two years.
Here's Firefly in September 2007, on her way to full recovery and adoption to a new home. The research project funded by WHW at the University of Liverpool suggests that it is difficult to assign an objective body condition score to ponies using the system designed for larger horses.
Researchers at the department of clinical science at Britain's University of Liverpool, with support from the World Horse Welfare charity, presented new research at the annual convention of the British Equine Veterinary Association(BEVA) last week.
The question: how accurate is conventional equine body condition scoring for weight loss management when the equine being evaluated is an overweight pony?
The study, entitled Managed Weight Loss in Obese Ponies: Evaluating Weight Change, Health and Welfare, involved five mature, overweight or obese ponies and aimed to restrict their feed intake (on a dry matter basis) to 1% of body weight of a chaff-based complete diet for 12 weeks.
During this time the ponies' weight change, health parameters and behavior were monitored. All ponies remained healthy throughout the whole trial and an appropriate and safe rate of weight loss was achieved.
Clare Barfoot BSc (Hons) RNutr, registered nutritionist and the research and development manager for SPILLERS® (British horse feed company) explained: “Body weight decreased at a steady rate. However, despite significant weight loss, the body condition scores of the ponies didn't change. This highlights the concern that body condition scoring may not be the most effective way to monitor early weight loss in ponies.”
Even in this well-managed study, the feeding activity of the dieting ponies was decreased by 74 percent compared to ad libitum intake, highlighting the need for a practical feeding system that is both effective at managing weight loss but is sensitive to behavioral needs.
The WALTHAM® Equine Studies group was closely involved with this study as it has been with other groundbreaking work on equine obesity, such as showing that an obese body condition score was associated with increased insulin resistance back in 2003, and developing the cresty neck scoring system.
In response to the study, the research group is in the process of developing a new condition scoring system designed specifically for ponies. “This will involve validating the relationship between actual measurements of body fatness and the external appearance of the pony,” said Alex Dugdale, lead researcher for the study at Liverpool University.

Laminitis: Obese Horses and Ponies in Greater Danger
by Fran Jurga | 7 May 2009 | Fran Jurga's Hoof Blog
A British study has examined the factors that affect the likelihood of recovery from grass-related laminitis, and concluded that obese horses are more likely to die.
In the study, members of the British Equine Veterinary Association (BEVA) documented cases over four years and found that when overweight horses develop grass-related laminitis, they tend to have more severe signs than those of optimal weight.
Reporting on the study conclusions, principal investigator and veterinary surgeon Celia Marr said “When (grass-related) laminitis does occur, overweight animals are more likely to die of the disease than their thinner counterparts. The animals with the best outcome tended to be those that had received acepromazine, a drug that improves the blood supply to the feet and relaxes the animal."
Marr's advice to horse owners: "Horse owners and vets are encouraged to ensure that horses and ponies are not allowed to become excessively fat as this can have a significant effect on their health, as we have seen in this study.”
Summary points of the study:
1. 107 cases of acute pasture-associated laminitis were recruited from first-opinion veterinary practices to study factors associated with clinical severity, survival and return to ridden exercise.
2. Of the horses in the study, 83 percent were overweight and there was a trend towards severe laminitis cases having a higher Body Mass Index (BMI).
3. Eight weeks after disease onset, 95% were alive.
4. Lower body weight, optimal body condition, mild rather than severe laminitis and acute/chronic founder were significantly associated with survival.
5. The clinical outcome was judged by a panel of three veterinarians as good in 72% of cases.
6. The clinical outcome was significantly associated with horse type; outcome was bad in none of the small horses compared with 34.1 percent of large ponies/cobs, 32.4 percent of small ponies and 30.0 percent of large horses.
The study was sponsored by the British Veterinary Association Animal Welfare Foundation (BVA AWF) and Merial Animal Health.
Hoof Blog note: Please remember that this study relates only to horses with pasture-type laminitis. There are several types of laminitis and perhaps one thing this study does is accentuate the differences in expectations that horse owners may have in their horses' recovery chances.

Favorite Video: Horse Owners Beware of Seasonal Weight Gain Over Winter Months
by Fran Jurga | 2 December 2008 | www.hoofcare.blogspot.com
 |
Most horses and ponies are not as overtly obese as this pony. The videos posted for you today explain the subtleties of weight gain in horses and their not-so-subtle effects on a horse's health. Chris Pollitt photo. (thanks!)
The red line on the thermometer is dropping. The blankets are out. The feed bucket gets an extra half a scoop. Soon it will be an extra whole scoop. Or two. In the deluxe barns, the heat comes on. "Can you bring the horses in early tonight? It's awfully cold...and make sure Bilbo has both his blankets on, ok?"
As countless horse owners continue to struggle with low-grade chronic laminitis and its more serious counterparts, we still seem to have as many overweight horses standing guard in winter paddocks as we did last winter. In spite of all the diet grain mixes, horse owners still love to feed their horses, just as they love to dress them in blankets. It's a visible sign that the owner cares, and is providing the best possible conditions for the horse. (Isn't it?) When the weather gets cold, adding more grain to the feed tub seems like a sensible, caring thing to do. (Isn't it?)
And when laminitis strikes, horse owners run through a gamut of emotions, from grief to guilt to an outpouring of excessive care and nursing. When, in most cases, it could have been avoided.
In this post you will find a three-part video from World Horse Welfare (formerly the International League for the Protection of Horses), a British-based charity that puts laminitis very high on its list of educational priorities.
World Horse Welfare horse care team leader Samantha Lewis shares good practical information with a horse owner in this video. She talks about the risks of laminitis, winter grazing, blanketing, weight taping, and a lot of other key concepts for horse owners.
She had my attention from the very first sentence: 80 percent of horses in Great Britain are overweight. How can that be? When she examines horses of different sizes and conformations, I start to understand that weight is a very deceptive variable in horses. And I may have been guilty of misjudging some horses in the past, according to Samanta's system.
I hope the regular readers of this blog will refer horse owners to this post to learn about the relationship of weight to laminitis and other health problems. If you're a vet or farrier, please recommend these video clips to your clients.
NOTE: In the shaded portion at the end of this blog article, you will see a small icon that looks like an envelope. If you click on it, you can forward this article (or any article in the entire archive of the Hoof Blog) to anyone you'd like to have this information. I think that the email icon shows up in some browsers and not others; sorry for this inconsistency.
This video set might make a great Christmas present instead of a bag of horse cookies.
Thanks to WHW for making these clips available. There's lots more information about obesity in horses on their website. For information about laminitis, please visit Dr. Chris Pollitt's laminitis research web site.
