Poisoning in horses is not a common occurrence, but when poisoning occurs, effects can be disastrous and far-reaching. Listing all toxic substances is impossible, as virtually everything on the planet can be toxic at sufficiently high dosages. What dose is safe and what dose is toxic varies with each toxin, each animal, and each situation. Factors that influence risk from a toxic substance include animal age, concurrent diseases, exposure to concurrent toxins or drugs, reproductive status, and route of exposure. This article will briefly summarize some of the more common toxic substances that can pose risks to horses in North America.
Herbal Supplements: The use of herbal supplements for horses has become common in recent years. Many people believe that if something is "natural," it must be safe and non-toxic. However, some of the most toxic substances on earth are completely natural (such as botulinum toxin, taxine in yew plants, and nicotine). Many herbal and natural supplements are inherently toxic, and many herbal products contain impurities and unknown amounts of "natural" ingredients. Herbal supplements are not well regulated, and studies investigating risks associated with use of these products in horses are lacking.
Plants, Feeds, and Feed Additives: Pastures can contain toxic plants and grasses that can pose risks at certain times during the year or under certain circumstances. Too many toxic plants exist to list here, and importance varies greatly with geographic location. However, all weeds should be viewed with suspicion and identified if possible. Additionally, grains can be contaminated with seeds from poisonous plants. Many shrubs, trees, and ornamental plants can be toxic to horses.
Hay and feed pellets can pose a toxic risk when unintended substances are incorporated into the feed. These substances include toxic weeds, toxic insects such as blister beetles, and dead animals that can serve as the origin of botulinum toxin production. Rotting, decomposing feeds or improperly stored haylage can also contain botulinum toxin. Pelleted or supplemental feeds can contain contaminants such as ionophores (such as momensin) or antibiotics due to mixing errors or contamination from transport vehicles. By-products from grain distillation can be present in supplemental feeds and can contain mycotoxins and antibiotic residues.

The Science of Wound Ointments for Horses
Equisearch.com - Full Article
A topical wound preparation can have a big impact--positive or negative--on the healing process. Here are tips from a wound-care expert for selecting the right product for your horse's injury.
By Christine Barakat
Your horse comes in from the pasture with a small cut on his chest. Maybe he hit the fence while playing or perhaps it was a tree.
In any case, the wound is fresh, clean and small. No need to call the veterinarian--you can handle this yourself. You reach for a tube of the thick wound ointment you've always used and smear a good-sized glob across the cut. That'll take care of it. Or will it?
Perhaps, says researcher Georgie Hollis, BSc, MVWHA, but it depends on what's in the tube.
The right preparation applied at the right time can protect a wound, support natural healing processes and minimize the risk of complications. But, warns Hollis, use the wrong type at the wrong time and you could actually slow down or even halt healing.
For the past three years, Hollis has been working to help make choosing the right ointment for each situation easier. A former podiatrist, she first observed the challenges of wound healing when she treated foot lesions in diabetic patients. In late 2006, Hollis, motivated by her personal interest in animals and horses in particular, began studying veterinary wound care. She now works with leading equine researchers, such as the University of Liverpool's Derek Knottenbelt, DVMS, MRCVS, in investigating and sharing information about how various treatment techniques affect healing.

Water and Dehydration Study Clarification
TheHorse.com
by: Multiple Authors
A 2008 Equine Veterinary Journal (EVJ) publication examining dehydration in working horses was summarized and printed onTheHorse.com on April 24, 2008, prior to its actual publication in EVJ. It was reviewed and approved by the researcher. The complete publication (in which Dr. Joy Pritchard was first author) was titled "Validity of indicators of dehydration in working horses: a longitudinal study of changes in skin tent duration, mucous membranes, and drinking behavior."
Recently, Dr. Olin Balch, a member of Veterinary Committee of the American Endurance Ride Conference (AERC) contacted Pritchard and TheHorse.com with committee concerns that the summary could be misinterpreted, especially where endurance horses are concerned.
Balch and Pritchard coauthored the following clarification.
Pritchard said, "My research studied changes in physiological parameters in 50 working horses pulling carts or carrying loads at moderate speeds in Lahore, Pakistan, over a period of 5 hours. While these results could be generalized to similar horses in developing countries, the conclusions are not directly transferable to any other horses, endurance or otherwise.
"The results illustrate that--in the sample population studied--neither a set of standardized skin tent tests, nor gingival mucous membrane dryness, nor other clinical parameters including heart rate, respiratory rate, and coat dryness/wetness were associated with hydration status," she continued. "Only volume of water drunk and drinking behavior were significantly associated with hydration status in these animals.
"The EVJ paper states clearly in the discussion and conclusion that working horses may not drink for internal and external reasons. Lack of drinking is not a conclusive sign of normal hydration status in the animals studied."
Balch said, "As a member of the Veterinary and Research Committees of the AERC, I believe that Dr. Pritchard has written a very important paper emphasizing that classic indicators of dehydration in horses (such as skin tent duration and mucous membrane dryness) may be quite misleading. The AERC sanctions approximately 23,000 horse starts in well-organized, veterinarian-supervised endurance rides in the U.S. and Canada annually.
"It is our collective experience, as experienced endurance veterinarians, that it is extremely common for horses in endurance rides to become dehydrated and yet refuse to drink water," continued Balch. "This is especially common early in rides where an excited horse may travel 25 miles without taking a drink. Additionally, we are convinced that exercising horses who refuse to drink water and become extremely dehydrated run the very real risk of suffering metabolic disorders. That is why riders must be attuned to their horses' water intake and take care to assure their horses are drinking adequately during endurance rides. The consequences of severe ileus or other forms of colic following dehydration and electrolyte depletion, although extremely rare at endurance rides, may lead to death.

AHC Seeks to Document Equestrian Access Issues on Public Land
The American Horse Council has launched a new effort to collect information on access issues equestrians are experiencing on federal lands. The center piece of this effort is an online form equestrians can use to report their personal experiences regarding trails and federal lands that have been closed to them or other access issues.
Americans who use horses and pack stock enjoy a unique experience when they ride on trails and public lands. It is an experience that ties them to the 'pioneer' era and provides not only a way to connect with America's vast and unique natural resources but a link with America's history and traditions. It is an experience that cannot be enjoyed without a trail system, trailhead access and areas for camping. It is an experience that Americans enjoyed even before there was a national park system and an experience they want to continue.
Unfortunately, equestrians are seeing an increasing loss of access through trail restrictions, trail closures, and use restrictions. Riders and stock users are being excluded from areas that they have historically traveled through and indeed first opened up. It is a loss of opportunities for riders, families, persons with disabilities, school groups and others. There seems to be a management environment less open to these traditional forms of use. Sometimes restrictions on equestrian use are done intentionally through management plans that reduce, restrict or eliminate horses, horse facilities, camping or grazing restrictions, cross-country travel restrictions or closures. Sometimes the restrictions are indirect though a lack of trail maintenance, or over regulation, or lack of services to the public like facilities that provide saddle and pack animals or parking for horse trailers.
In order to better combat this disturbing trend the AHC is asking equestrians to document examples of trails or entire areas that have been closed to equestrians on federal land (National Forest Service, National Parks Service, and Bureau of Land Management, etc). The AHC is seeking all relevant information concerning these closures such as the reason for the loss of access, details concerning any public process that was involved and the history of equestrian use on the closed trail or area.
The AHC is also interested in examples of attempts to bar equestrian access that have been defeated.
"The reduction of trails, trail heads and the closure of public lands to horses and pack animals is a continuing problem for equestrians. However, there is no centralized, comprehensive database that documents any loss of access and even fewer specific examples," said AHC President Jay Hickey. "We hope by giving equestrians a place to report their experiences we can get a better picture of the problem and use that information to fix it."
The AHC is asking all recreational riders to visit the AHC website and report any access issues they have had using this electronic form https://www.horsecouncil.org/survey.php. This will be a permanent feature of the AHC website.
"The AHC is committed to preserving equine access to public lands. It is very important for these efforts that we have evidence that demonstrates the extent of the problem and the need for action on the part of Congress or the federal land agencies," said Hickey.

Joint supplements - a vet's perspective
Question 1:"what are the best and least expensive joint supplements to use on my horse for healthy joints?"
Question 2: "what are the benefits of Adequan vs Legend?"
Answer by Susan Garlinghouse, DVM, MS:
Answer 1: Here’s my opinion about joint supplements, both oral and injectable.
There’s no data to support that providing any sort of supplement prior to actual clinical signs of degenerative joint disease actually delays its eventual onset. However---if we consider what we ask these horses to do, even the best conditioned, most intelligently managed horse is going to have *some* degree of inflammation in its joints after a ride, and even though that inflammation may be insufficient to appear on an x-ray or in a lameness exam, it makes sense to protect those joints as much as possible. As such, I give my horses joint supplements when they’re working hard; and the 17-year-old campaigner I’m currently riding is getting practically marinated in the stuff, even though he doesn’t have a whisper of lameness, just because he’s working hard and is seventeen years old.
Of the oral forms of supplements, the best data available is from NutraMax Labs, that developed and markets the original oral supplement, Cosequin. They do show a measurable benefit provided by regular dosing, BUT---even the most expensive, name brand stuff out there only has a bioavailability of about 3-4%---which means you have to feed boatloads of it to get a smidgen of it into the circulation where it can eventually be taken up by inflamed joint tissue. Pretty expensive stuff for most of it to end up in a poop pile (though I’m happy to report the flies on my property feeding on that poop have never looked so spry). The bioavailability goes down when you get into the generic versions---even though the ingredient label may still say “chondroitin sulfate”, the label doesn’t tell you the Daltons (size, more or less) of the molecule in question. The bigger (read “cheaper”) the molecule, the less likely it is to be absorbed in the GI tract and thus get used effectively. There’s a good bit of data that supports the notion that most of the generic joint supplements available at Costco don’t do a darn thing, just because the molecule is too big to be absorbed. And remember, the very BEST source out there is only 3-4% available when fed orally.
That being said, I hugely prefer going the injectable route, because then I’m bypassing the GI tract entirely and most of the injected dose is getting to inflamed tissue where it belongs. Yes, I know the injectables are more expensive per dose, but I’d rather pay more for a vial of liquid gold that’s almost entirely bioavailable, then paying a lot less for an oral supplement that’s mostly ending up in the manure dumpster. Even I can do that math. I’ve heard differing things about the oral hyaluronates, but still prefer going the direct injectable route with that as well, for basically the same reasons.
Because I own an animal hospital and mostly work on companion animals for a living, I use the injectables in a whole lot of different species and it helps a bunch, especially in creaky, arthritic old dogs. Sometimes it’s hard to see a tangible difference in horses that are still pretty much moving okay, but I know a dog is feeling better when he starts asking to go for walks again, jumping into the car without help, whatever. I always tell my owners not to expect a miraculous improvement overnight, because we’re not just masking symptoms with a painkiller, we’re approaching the source of the disease process directly, and that takes some time. I usually dispense enough for the initial loading period of six weeks or so and sometimes then I’ll ask the owners if they saw an improvement and would they like a refill. Sometimes they tell me they didn’t see much benefit, so nope, they’ll skip the refill. I can pretty much set my watch that a month later, they’ll be calling for that refill, because they didn’t realize how much better old Duffy was until they STOPPED giving him the Adequan. I’d guess I probably have about a hundred patients on it in my practice at any given time.
I couldn’t tell you the efficacy of the generic injectables. I know they’re out there, but I use the brand name Adequan and/or Legend in my practice, just because I’m positive those are effective, and I need to use that not only for my own animals, but also for my clients.
So, I know you’re looking for something inexpensive to feed, but I’m going to go out on a limb and also assume you want the most bang for your buck. My advice would be to skip all the oral supplements entirely, with the possible exception of some source of omega-3 fatty acids, which have a different mode of action but are still pretty good for assorted inflammatory conditions, including those affecting the joints. The most cost-effective source of the O-3s is maybe a cup or two of freshly ground whole flax seed---grind it up yourself in an electric coffee grinder, stick it in baggies into the freezer and give your horse a baggie once a day.
Take whatever your annual budget is that you were planning on spending on oral joint supplements and figure out how much Adequan, or Legend, or both, that you can afford. Do that. Resis the urge to feed something other than the aforementioned flax seed. You’ll get more benefit from an Adequan or Legend injection once a month, or twice a year, or whatever suits your budget, than you will by feeding the oral supplements on a daily basis---especially if the oral supplement is one of the cheap ones that oh-by-the-way, has such low bioavailability that 99% of it is going into the dumpster.
Hope this helps. BTW, all the above comments also apply to arthritic dogs, kitties, bunnies and darn near every other species out there. I won’t comment publicly on its applicability to humans, because I’m not licensed for that species and the DEA would be sending me nastygrams as soon as they finished tracking down whoever it was that sold propofol to Michael Jackson.
Susan Garlinghouse, DVM
Answer 2:
That’s a really good question, and I’m going to go out on a limb here and assume you’re interested more in a practical answer than debating the p-values and historical influence of the senate subcommittees on its use, so forgive me if I gloss over some of the finer biochemical details. Both Adequan and Legend tend to achieve the same end goal of by slightly different pathways. Both have the end effect of increasing the concentration of hyaluronic acid in joint capsules and tendon sheath (and a few other assorted locations). Hyaluronic acid is a nifty little ‘backbone’ molecule that binds water within the joint fluid---the best analogy I can think of is one of those coat hangers with all the clips on it for hanging pants and skirts and things. The more coat hangers you have, the more things you can grab onto. So, the more hyaluronic acid, the more water molecules you can grab. That’s handy, because water is about the only substance on earth that doesn’t compress under pressure and so is a really great shock absorber within the joints. That helps prevent rubbing and friction within the joint during high-concussion which is likely to result in inflammation and, over time, arthritis.
So Adequan acts by stimulating the cells that line the cartilage (that’s the layer inside the joint capsule that covers the ends of the bones) to naturally produce more hyaluronic acid. Legend is actual hyaluronate itself, which after injection, is preferentially taken up by inflamed tissues throughout the body, including within joints. Dunno how the body ‘knows’ but that applies to lots of different processes in the body we still haven’t figured out but are happy to take advantage of, anyway. Hyaluronate is also commonly one of the substances injected directly into a joint, usually along with a small amount of a long-acting steroid, but that will only directly affect one joint; whereas systemic administration will affect pretty much all the joints within the body, though to a lesser overall extent. If you’ve ever heard of a horse getting his hocks injected (or knee, or fetlock or coffin joint), that’s what they’re talking about. Not something you do lightly, though, because directly injecting a joint is definitely a veterinary procedure that has to be done exactly right.
If you absolutely had to choose between Adequan or Legend, then the general concensus in the online vet community (we have our own discussion groups where we chat about this kind of thing and no, they’re not open to non-vets) is that Adequan is preferred if you have soft tissue involvement (like tendons and ligaments), and Legend is a bit preferred for straight arthritic conditions. Adequan, of course, also benefits arthritic conditions as well, but seems a bit better for general wear-and-tear. If you want the absolute best of both worlds, then do both, and that’s what I do for my horses that are working hard or have some issues they’re dealing with.
If I had to choose between one or the other for preventative maintenance, then I would probably go with Adequan, because I think it benefits tendon and ligaments as well as strictly joints a little better, and I want to cover as many bases as possible. For an older horse with DJD, then I think you’ll get more benefit with Legend. As I said, though, the gold standard would be both but hey, we can’t all wake up with Oprah Winfrey’s budget every morning.
Someone else asked me if they could only afford a few injections a year if there would be any ‘spiking’ effects and no, there’s no downside to less frequent dosing except that you’re just not getting as much benefit as you would with frequent administration. If I had to time it around a riding season, I would probably use up my budget starting a month or so before the first ride, when presumably, you’re starting to ramp up workouts. If you can give the horse some additional during the season, better. If you can give them some more right at the end of the season when they’re about ready for a rest and probably have some active inflammation to one extent or another, that would be great.
The other question someone asked me was whether this was something an owner could do, versus having to call out the vet. Adequan is an intramuscular injection, so most owners can do that. Some drugs (like procaine penicillin) you have to be careful to keep out of veins and such, but Adequan isn’t a problem if you happen to hit a vein. Some of the racetrack people prefer Adequan IV, though I go IM myself. Legend might be bioavailable if you injected it IM, but is best IV---so if an owner were comfortable doing an IV injection themselves, fine. It’s legal for an owner to administer meds to their own horse by any route, but starts getting into gray areas doing it to anyone else’s horse, aside from potential liability problems if you do it wrong. So if your vet is willing to supply you with either Adequan and/or Legend, and/or you’re otherwise able to obtain it somewhere (I don’t know if you can buy it online without a prescription, you probably can), and you’re comfortable injecting your own horse, go for it.
Hope this helps.

Hyaluronate is also commonly one of the substances injected directly into a joint, usually along with a small amount of a long-acting steroid, but that will only directly affect one joint; whereas systemic administration will affect pretty much all the joints within the body, though to a lesser overall extent. If you’ve ever heard of a horse getting his hocks injected (or knee, or fetlock or coffin joint), that’s what they’re talking about. Not something you do lightly, though, because directly injecting a joint is definitely a veterinary procedure that has to be done exactly right.
If you absolutely had to choose between Adequan or Legend, then the general concensus in the online vet community (we have our own discussion groups where we chat about this kind of thing and no, they’re not open to non-vets) is that Adequan is preferred if you have soft tissue involvement (like tendons and ligaments), and Legend is a bit preferred for straight arthritic conditions. Adequan, of course, also benefits arthritic conditions as well, but seems a bit better for general wear-and-tear. If you want the absolute best of both worlds, then do both, and that’s what I do for my horses that are working hard or have some issues they’re dealing with.
If I had to choose between one or the other for preventative maintenance, then I would probably go with Adequan, because I think it benefits tendon and ligaments as well as strictly joints a little better, and I want to cover as many bases as possible. For an older horse with DJD, then I think you’ll get more benefit with Legend. As I said, though, the gold standard would be both but hey, we can’t all wake up with Oprah Winfrey’s budget every morning.
Someone else asked me if they could only afford a few injections a year if there would be any ‘spiking’ effects and no, there’s no downside to less frequent dosing except that you’re just not getting as much benefit as you would with frequent administration. If I had to time it around a riding season, I would probably use up my budget starting a month or so before the first ride, when presumably, you’re starting to ramp up workouts. If you can give the horse some additional during the season, better. If you can give them some more right at the end of the season when they’re about ready for a rest and probably have some active inflammation to one extent or another, that would be great.
The other question someone asked me was whether this was something an owner could do, versus having to call out the vet. Adequan is an intramuscular injection, so most owners can do that. Some drugs (like procaine penicillin) you have to be careful to keep out of veins and such, but Adequan isn’t a problem if you happen to hit a vein. Some of the racetrack people prefer Adequan IV, though I go IM myself. Legend might be bioavailable if you injected it IM, but is best IV---so if an owner were comfortable doing an IV injection themselves, fine. It’s legal for an owner to administer meds to their own horse by any route, but starts getting into gray areas doing it to anyone else’s horse, aside from potential liability problems if you do it wrong. So if your vet is willing to supply you with either Adequan and/or Legend, and/or you’re otherwise able to obtain it somewhere (I don’t know if you can buy it online without a prescription, you probably can), and you’re comfortable injecting your own horse, go for it.
Hope this helps.

Why Horses Stumble
TheHorse.com
Heather Smith Thomas
Some horses stumble or stub their front toes frequently, with the toe hitting the ground while the knee is still bent and the leg collapses instead of taking weight. The horse's head and neck drop down, but he usually catches himself by rapidly extending the other leg. Most of these horses are not lame, yet might occasionally fall to their knees or go down with a rider. The habitual stumbler might manage fine when running free, but tends to trip and stumble when being ridden or led. The stumbling horse is frustrating to ride, and he can be dangerous.
Stumbling can be caused by a number of things, including long toes, long feet, hoof imbalance, laziness or boredom, and in some instances devious behavior--a few horses learn they can get out of work if they stumble because a concerned rider thinks there is something wrong and ends the ride. Stumbling can also be due to inadequate conditioning (such as a young horse unaccustomed to carrying a rider, or a horse whose muscles are out of shape), poor conformation, incoordination, joint problems, chronic foot pain, damage to the central nervous system (brain and spinal cord), brain disorders such as narcolepsy (sudden attacks of sleep), or weakness due to fatigue or illness.

Suspensory treatment: Mending With Marrow
TheHorse.com
by: Heather Smith Thomas
Suspensory ligament injury is a common problem in athletic horses, and it is often slow to heal, with a high recurrence rate when a horse returns to work. Douglas Herthel, DVM, of Alamo Pintado Equine Clinic in Los Olivos, Calif., has been using bone marrow in a new technique for treating these injuries. He began his study in 1995, looking at bone marrow, which contains stem cells, monocytes, platelets, and fat.
"A recent unpublished survey that was done at UC Davis indicates this is the single most common cause of lameness in the show horse," says Herthel of suspensory ligament injury. "It can affect almost any horse that is in athletic performance.
"The experience we had in treating these during the past 25 years--prior to stem cell therapy--was fairly dismal," he continues. "Ours is a referral practice, and we usually got the cases after they'd been looked at and treated numerous times. We were averaging only 20% success in return to full work."

Study: Offering Water an Accurate Gauge of Dehydration
Thehorse.com - Full Article
by: Christa Lesté-Lasserre
April 24 2008
If you lead a horse to water, you might not be able to make him drink, but it's still a great way to gauge whether he needs that water or not, according to recent British research examining working horses and dehydration levels.
The researchers found that the commonly used "skin tent test" (pinching up a section of skin to note the time it takes to return to its normal position) varies greatly according to the horse's age, the humidity of the coat, and the site of the skin tested. Furthermore, it has no significant connection with the actual state of hydration in the horse, according to the study.
Because of this, the skin tent test is not a valid method for evaluating dehydration in horses, said Joy Pritchard, PhD, DVM, co-author of the study and a researcher at Bristol University. Pritchard is also head of animal welfare at Brooke Hospital for Animals, a U.K.-based charity that focuses on equids in developing countries.

House Funding Bill Excludes Animal Identification System
Thehorse.com - Full Article
by: Pat Raia
June 16 2009
The National Animal Identification System (NAIS) will receive no new funding under a 2010 spending bill proposed by the U.S. House of Representatives Agriculture, Rural Development, and FDA appropriations subcommittee. Chairwoman Rosa L. DeLauro (D-Ct.) announced bill details on June 11.
The NAIS is a nationwide livestock database designed to help federal and state agencies locate and track the movement of animals in the event of disease outbreaks or natural disasters.
The program uses data provided by livestock producers and property owners to assign identification numbers to individual animals and to properties where animals are born or reside. Registry participation is voluntary. But the program has failed to attract substantial support among livestock producers.
"There is overwhelming concern about NAIS registration becoming mandatory. There is also opposition to the whole concept by some (who fear) that they will have to ID their animals to move them through commerce," said Nancy Robinson, vice president of government and industry affairs for the Livestock Marketing Association.

Horses React to Human Heart Rates, Study Finds
Thehorse.com - Full Article
by: Nancy Zacks
July 01 2009
An increase in a human's heart rate affects the heart rate of the horse they are leading or riding, researchers at the Swedish University of Agricultural Sciences recently reported.
Linda Keeling, PhD, and colleagues tested horses and riders to see if humans inadvertently communicate fear and anxiety to horses. Using heart rate as a fear indicator, the researchers asked 20 people with varying levels of horse experience to walk and ride 10 horses from Point A to Point B four times. The researchers told participants an umbrella would open as they rode or led the horse on the fourth pass. The umbrella never opened, but heart rates in both horses and humans increased during the fourth trip between the points, when the human expected the umbrella to open.
"The increase in the horses' heart rates probably means that they are more alert and prepared to react to any potential danger," Keeling said. "In the wild, horses are adapted to respond to other animals in their group. A startle reaction is more likely when the horse is very alert."

So what happens to the Mongolian horses after the event?
July 1 2009 - Karen Chaton Enduranceridestuff.com
I wrote and asked the Aventurists that question a couple of days ago, and still have not gotten a response. However, I did get a couple of answers from Long Rider’s who have ridden in Mongolia.
I was wondering what might happen to the horses after they do their 25 mile (40 km) section of the Mongol Derby. Somehow, they need to get back home! Obviously the (possibly up to 26 used on each leg) horses won’t be hauled back home in a trailer. The consensus is that most likely the animals will be turned loose to find their way back home. It sounds like these are pretty smart horses.
Yet, that effectively doubles the distance that they must go. Granted, without the rider on their return trip. I know the website states that this race is not a test of endurance for the horse. I would consider it a test of endurance for my own endurance horse to be ridden 25 miles one day and then be turned around and set loose to find their way home in the next few days. Hopefully these guys will let the horses stay a day or two and rest and rehydrate and eat well before sending them on their way.
I have a quote from Bonnie Harpp who has ridden in Mongolia: “No Mongolian is going to give up his best horse for such a race. Horses are a spiritual symbol to Mongolians. They will pull out a few old nags or, I believe, go out and pull some of the more acceptable looking horses off the steppe. There are no barns there or corals. It is entirely different. People here would never believe it.”
I did the math to figure out how many 25 mile legs each rider will have to do per day in order to finish the entire race within a week. Since this is an event challenging the endurance of the rider rather than the horse I would think that each rider would be riding at least 50, 75 or 100 miles per 24 hour period. You couldn’t finish in three weeks if you only rode 25 miles per day. If you rode 50 miles per day, which would take two Mongolian horses each going 25 miles every single day - and you didn’t take any days off you would be riding for 12 days.
Most very fit endurance riders I know would be knocked on their butt riding 24 different horses 25 miles each for 12 days straight. I think they would find it very difficult riding their own same horses that distance in that same time period. Especially given the more extreme and rough conditions that these participants are sure to encounter. Endurance riders in the US are pretty spoiled and used to lots of creature comforts. These guys aren’t going to finish every night to a nice meal (after having lunch possibly provided, or at least easily made themselves) with a shower and a nice already made bed waiting for them. They are going to have a rough time.

Endurance riding techniques help Sir Ranulph Fiennes climb Everest
Horseandhound.co.uk - Full Article
Liz Peplow
22 June, 2009
Endurance riding techniques were behind Sir Ranulph Fiennes' successful Everest attempt last month, his wife Louise has told H&H.
When the 65-year-old adventurer conquered Mount Everest on his third attempt on 21 May, he attributed his success to his wife.
"He told me he owed his achievement to me, which was really something for him to admit," said the endurance rider, who, as Louise Millington, was a member of Endurance GB's Cheshire Group, before she married Sir Ranulph and moved to Exmoor in 2005.
"I have been indoctrinating him with endurance principals — fundamentals like hydration, avoiding build-up of lactic acid and using electrolytes."
Louise said how, as part of his training, she accompanied him to a marathon in Singapore.
"I got him to drink properly and to eat lots of pasta and slow-release energy bars," she explained. "He finished an hour and a half quicker than before. He was tired, but not ill.

Can Natural Hoof Care Reverse Laminitis?
Debra R. Taylor DVM, MS, DACVIM at the Auburn University College of Veterinary Medicine thinks it's possible, and is doing the research to prove it. EasyCare, Inc has helped by providing funds and encourages those who have an interest in natural hoof care to do the same. EasyCare's donation helps fund intern Adam Cooner.
Dr. Taylor is recording and studying the results of natural hoof care on chronic laminitis cases. Hoof care practitioner Pete Ramey and his wife, Ivy, are currently traveling to Auburn every three weeks to expand the preliminary study - hopefully to include 50 horses. The study has consistently shown rotation reversal, increased sole thickness and profound improvement in levels of soundness. Several case horses have also demonstrated reversal of distal descent of P3. The goal is to publish this data as a scientific paper; it would be the first time a successful method of reversing chronic laminitis has been published. If you have a laminitic horse you would like to add to the study (and can haul to the University) please contact Dr. Taylor at the vet school. Boarding is available at nearby farms.
Dr. Taylor has begun additional studies to prove out the clinical relevance of the research findings of Robert Bowker VMD, PhD. This summer she will use ultrasonography, cadaver dissection, histology, radiography, MRI and CT to establish parameters for evaluating lateral cartilage and digital cushion development. This preliminary cadaver study will pave the way for a planned study to track the caudal foot development in live horses over time using radiography, ultrasonography, MRI and/or CT.
Currently, there are a limited number of veterinarians in the field that recognize the significance of internal foot development, and its ramifications to the horse's longevity and soundness. Experts in the field of hoof imaging, rarely address the anatomy, structure or health of the lateral cartilages, the digital cushion or heel depth when interpreting MRI results on horses with heel pain - in other words, half of the total volume of the foot is rarely taken into consideration. This study linking Bowker's cadaver studies to MRI, ultrasound and radiographic parameters should become critical to the future of lameness treatment and prevention.

Woman, horse hike across US
photo:Ann Byrns and her horse, Winnie, rest in Ellenville on Wednesday. They're heading to a new life in California.By Stephen Sacco
Times Herald-Record
Posted: June 19, 2009 - 2:00 AM
ELLENVILLE — Ann Byrns' problems used to center on financial strife. But on Wednesday, her biggest problem was finding a spot to park her horse and herself for the night.
Byrns is walking across country — from Massachusetts to California — with her rescued 3-year-old mustang named Winnie.
Less than a year ago, Byrns owned a retail shipping business in Amherst, Mass. The business hit hard financial times, with the recession delivering the fatal blow. By August, at age 57, she lost her business and life savings.
Isha Gregory, Byrn's 27-year-old daughter, and her husband had the solution: come live with us in Paradise, Calif.
But it's a long way to Paradise — about 3,000 miles. And though Byrns could afford to get herself there on money from a small pension she receives from the University of Connecticut — where she worked before opening her own business — she didn't have the money to transport Winnie.
"So, I decided to walk with my horse," Byrns said. "I made a commitment to Winnie and I wasn't going to lose her." Byrns says on her Web site that Winnie gave her something to wake up for in the morning during the darkest days when she was losing her business. She also states on her site that she wants to draw attention to the plight of the mustang.
Byrns' son has created a Web site for the trip, that started June 3, and also bought his mother a notebook computer, where she blogs and checks her e-mails. People can sign up to become "fans of Winnie" as a way of funding Byrns' journey.
On Wednesday, Byrns was in Ellenville, where she had stopped so Winnie, who carries a saddle pack of supplies and camping gear, could see a veterinarian. Byrns has health insurance through her retirement benefits from the university, and Winnie has health insurance through a gift from a patron.
The journey is a slow one: an average of about 7 miles per day, and no more than 13 to 14 miles per day, tops. On this schedule she will be arriving in California sometime in 2010.
"Most people have been really great to us," said Byrns. "When something happens, there always seems to be an angel there to help." People, however, haven't been so responsive to Byrns' sign urging them to pass them by "slow," she said.
"As a horsewoman, I find the prospect of walking across country with a horse overwhelming," said Cori Nichols of Norwegian Wood Farm in Kerhonkson. "But (Byrns) is very self-sufficient and has it all planned out."

Probiotics and Prebiotics

May 01 2009
Stress, illness, and age can disrupt beneficial microflora in the horse's gastrointestinal tract; here are tips on keeping these microbes healthy.
Lately, we have seen commercials that promote striking the balance of "good bugs" in our own gastrointestinal (GI) tracts. Our local grocery likely has a variety of colorfully packaged yogurts boasting "live and active cultures." These products are designed to keep the good microflora happy and reduce the amount of detrimental bugs in our guts, but the jury is largely still out on their efficacy. Similarly, horses' GI tracts also need to reach this balance, but since these animals have a unique digestive system that enables them to process and utilize forages, different types of bugs are required.
Microbes in the hindgut (the large intestine and cecum) of the horse break down and ferment fibrous portions of roughages, producing volatile fatty acids that serve as a significant energy source. These microbes also create B vitamins and other nutrients essential to the health and well-being of the animal, and they help reduce the risk of overgrowth of potentially harmful bacteria such as Salmonella and Clostridium difficile. The microbial population (which includes bacteria, protozoa, yeasts, and fungi) of the hindgut must be healthy, and its numbers must be at appropriate levels for proper digestion. Bacteria make up the largest group, but the other good bugs play an important role.
When the levels of the good bugs wane--as in cases of stress, travel, or antibiotic administration--there are ways to replenish them with the help of probiotics and prebiotics. And while not available in your supermarket aisle, these equine products are readily available elsewhere. It's important to note there is limited scientific evidence in peer-reviewed journals on probiotics and prebiotics, so ask your veterinarian to advise you on the use of these products and where to find them.

No Sugarcoating: Diagnosing and Managing the Insulin-Resistant Horse
Thehorse.com - Full Article
by: Emmy Widman, Washington State University College of Veterinary Medicine
October 19 2008
Insulin resistance can lead to Type II diabetes in people. In horses, it can lead to what is called equine metabolic syndrome (EMS).
"We have diagnosed five or six horses (with EMS) here at Washington State University's Veterinary Teaching Hospital during the past year," said Nicki Wise, DVM, a WSU second-year equine medicine resident. "Most presented with chronic laminitis, which is the one of the biggest problems for horses that have EMS."
Beyond chronic laminitis, a horse's appearance could raise suspicions of EMS.
"Often, horses with EMS have abnormal fat deposits over their neck, rump, tail, and eyes," Wise said. "The disease is closely related to Cushing's disease. Technically it is different, but a lot of the signs are the same. Generally, the disease is not life-threatening, but it will probably shorten their lifespan if these horses are not managed properly."
Ponies, Arabians, and Paso Finos are among the common breeds that the condition is found in, but any horse can suffer from it. EMS also tends to occur in middle-age to older horses, and those that are obese and have a sedentary lifestyle.

Insulin resistance can lead to Type II diabetes in people. In horses, it can lead to what is called equine metabolic syndrome (EMS).
"We have diagnosed five or six horses (with EMS) here at Washington State University's Veterinary Teaching Hospital during the past year," said Nicki Wise, DVM, a WSU second-year equine medicine resident. "Most presented with chronic laminitis, which is the one of the biggest problems for horses that have EMS."
Beyond chronic laminitis, a horse's appearance could raise suspicions of EMS.
"Often, horses with EMS have abnormal fat deposits over their neck, rump, tail, and eyes," Wise said. "The disease is closely related to Cushing's disease. Technically it is different, but a lot of the signs are the same. Generally, the disease is not life-threatening, but it will probably shorten their lifespan if these horses are not managed properly."
Ponies, Arabians, and Paso Finos are among the common breeds that the condition is found in, but any horse can suffer from it. EMS also tends to occur in middle-age to older horses, and those that are obese and have a sedentary lifestyle.

Easyboot Gaiter R&D and Improvements
From the horse's mouth
June 15, 2009
I've been testing several different Easyboot Gaiter designs and I'm seeing some very good results. I'm currently testing gaiters on the Easyboot Glove (my favorite hoof boot) and plan to update the entire EasyCare hoof boot range after we decide on the new design.
One of the designs that is working very, very well is a new concept that has an internal liner. The liner is attached but moves independently of the outer gaiter. Carol Layton of Australia has been using an internal neoprene cuff with much success and her testing started me toward the new design.

Water: The Overlooked Nutrient
Thehorse.com - Full Article
by: Kentucky Equine Research Inc.
May 17 2009, Article # 14174
The most important nutrient in the horse's diet is one that is rarely added to feeds: water. Although it is often overlooked in discussions involving equine nutrition, water could be considered the first limiting nutrient of all horses, as they cannot survive for as many days without water as they can without feed.
The amount of water required by the horse is determined by the magnitude of water losses from its body. These losses occur through feces, urine, respiratory gases, and sweat and, in the case of lactating mares, milk.
These losses are affected by the amount, type, and quality of the feed consumed, environmental conditions and the health, physiological state, and physical activity of the horse. Horses will generally consume as much water as they need if given access to a palatable water source.
Horses at rest in a moderate climate will generally consume between three and seven liters of water per 220 lb (100 kg) of bodyweight. This translates to around 4-9 gallons for an 1,100-lb (500-kg) horse.

Montana Horse Slaughter Bill Becomes Law
Thehorse.com - Full Article
by: Pat Raia
May 04 2009, Article # 14098
A measure promoting privately-owned horse processing plant development in Montana became law on Friday when Gov. Brian Schweitzer allowed the bill to lapse into law.
HB 418 insulates prospective plant developers from permit and licensing challenges on environmental and other grounds, and awards attorney and court fees to plaintiffs in cases District Courts deem harassing or without merit.
The measure automatically became law after Schweitzer declined to sign or veto it 10 days after it reached his desk.
Schweitzer previously vetoed the bill, and sent an amended version back to the legislature. But legislators returned the bill to its original form and sent it back to Schweitzer a second time.

Hard at Work or Hardly Working? Equine Work Intensity
Thehorse.com - Full Article
by: Kentucky Equine Research Inc.
May 11 2009, Article # 14148
Optimal nutrition of the performance horse hinges foremost on the exercise it performs. Just as the diet of a human bodybuilder is dissimilar to that of a marathon runner, most horses are fed with performance goals in mind. Therefore, accurately assessing the level of work performed by a horse is essential in determining the amount and type of feed offered.
Energy is produced by aerobic or anaerobic metabolism. The breakdown of carbohydrates, fats, and protein into energy with the involvement of oxygen is termed an aerobic reaction.
Because oxygen is required, this energy-producing process is slow. The conversion of glucose or glycogen to lactic acid does not require oxygen and is therefore an anaerobic reaction, a process that produces energy quickly. Equine nutritionists divide work into three classes based on how horses derive energy from their bodies to fuel exercise.
High-intensity, short-duration work includes performance events with a primary sprint component...

Feeding Fat for Energy and Performance
Thehorse.com - Full Article
by: Karen Briggs
July 01 1997, Article # 688
If there was a nutritional buzzword that was started in the '90s, it was fat. We fitness-conscious (and frequently overweight) North Americans still might not fully understand the differences between "good" cholesterol and "bad" cholesterol, but we all know how to count our fat grams! While we struggle to keep our diets as low-fat as possible, fat has a different focus when it comes to our horses because it's only in recent years that we've recognized the value of raising the fat level in an equine athlete's diet.
Of course, the average human diet (at least in North America) contains well over that recommended 30 grams of fat per day that nutritionists enthusiastically endorse. The horse's natural diet, in contrast, contains almost no natural fat at all. Forages and fibers contribute none, and most grains fed to horses only contain between 2% and 3.5% fat overall. While this leaves the horse at low risk for cardiovascular clogging, it does mean that, traditionally, carbohydrates have been considered the obvious and "natural" energy source for performance horses, and fat rarely has been considered, beyond that little splash of corn oil that's considered good for a shiny coat. Only in the last couple of decades have we begun to realize that fat is also a valuable energy source--and one with many advantages.
Why Feed Fat?
High-fat diets (anything over and above the 2% to 3.5% supplied by a standard grain-plus-forage diet) provide several perks, most notably in terms of energy production for high-level equine performance. Pound for pound, fat supplies almost 2 1/2 times as much energy as the equivalent weight of carbohydrates or starches (traditionally supplied by grains such as oats, corn, or barley). So, if you want to supply more energy to your horse without increasing his overall feed intake, supplementing the fat in his diet can be an excellent way to accomplish that.

Recreational Trails Program Up For Reauthorizatioin
May 5, 2009
The American Horse Council is working to preserve the Federal Highway Administration's Recreational Trails Program. If Congress does not take action this year this program could no longer be available to recreational riders.
The RTP provides funding directly to the states for recreational trails and trail-related facilities for both non-motorized and motorized recreational trail uses. It was created in 1991 as part of the Intermodal Surface Transportation Efficiency Act of 1991 and was last re-authorized in 2005 as part of the Safe, Accountable, Flexible, and Efficient Transportation Equity Act: A Legacy for Users, this law is about to expire. The RTP will have to be re-authorized in the next national surface transportation program bill if it is to continue.
Since its inception the RTP has provided approximately $677 million for thousands of state and local trail projects across the country, including many that benefit equestrians. RTP projects consist of construction, maintenance and restoration of trails and trail related facilities as well as the acquisition of easements or property for trails.
Although each state manages its own program, 30% of RTP funds must be spent on non-motorized projects like equestrian trails, 30% on motorized, and 40% percent on multiuse projects.
"The RTP is one of the few sources for federal funding of trail projects that are not on federal land. The program is a great resource for equestrians to fund projects in their state and local parks," said AHC Legislative Director Ben Pendergrass.
In the coming months Congress is expected to begin work on the next 5 year highway bill. The AHC, in conjunction with a broad coalition of recreational trail users is requesting that Congress not only re-authorized the RTP, but also increase funding for the program to $555 million to be spent over the five years of the bill.
The AHC urges recreational riders to contact their members of Congress to voice support for this program. "This is a great program and I hope equestrians will take the time to call or write their Representatives and Senators and let them know this program is important to the horse community," said AHC President Jay Hickey.

USEF Drugs and Medications Guidelines - download pdf
The United States Equestrian Federation (USEF) is the national governing body for equestrian sport and is a member of the U.S. Olympic Committee. The USEF is responsible for enforcing the rules of 27 breeds and disciplines. Formerly this organization was known as the American Horse Shows Association (AHSA). The name may have changed, but the mission of its Equine Drugs and Medications Program has stayed the same since the program's inception in 1970.
Over the past 38 years, the Equine Drugs and Medications Program has worked to protect the welfare of equine athletes and ensure the balance of competition. Currently, the program utilizes veterinarians and technicians around the country to collect blood and urine samples from horses competing at USEF events.
The USEF also contracts with the American Quarter Horse Association (AQHA) to enforce the AQHA'S drug rules by collecting samples at Quarter Horse competitions for analysis. Additionally, the USEF is responsible for testing competitions throughout the United States that are operated under the rules of the Federation Equestre Internationale (FEI), the international governing body of equestrian sport headquartered in Lausanne, Switzerland.
In 2007, almost 17,000 blood and urine samples were collected and analyzed by the program, representing nearly 13,000 horses randomly selected for testing. Since 1995, the USEF has operated its own equine drug testing and research laboratory.
Drugs and medications are classified by the USEF's Drugs and Medications Rule as being permitted, restricted, or forbidden.
Permitted substances include dewormers, antibiotics (except procaine penicillin), anti-fungals, antiprotozoals, vitamins, electrolytes, and anti-ulcer medications. Caution is urged if one is using so-called herbal or natural products, since plants are commonly the source for pharmacologically potent, forbidden substances such as cocaine, reserpine, and marijuana.
Restricted medications include specific non-steroidal anti-inflammatory drugs (NSAIDs), methocarbamol (muscle relaxant), and dexamethasone (corticosteroid). Restricted drugs are allowed to be present in the horse at the time of competition provided they do not exceed the levels specifically set for each drug.
Currently, no more than two approved NSAIDs are permitted in a horse's system at the same time, as long as neither is found in excess of respective restrictive levels. One exception to this regulation is flunixin and phenylbutazone, which are not permitted in a horse at the same time. A seven-day withdrawal from one of these two NSAIDs is recommended before initiating treatment with the other. In addition to flunixin and phenylbutazone, other NSAIDs that are allowed below restrictive levels include: naproxen (Naprosyn), meclofenamic acid (Arquel), firocoxib (Equioxx), diclofenac (Surpass), and ketoprofen (Ketofen).
Very specific dose and time recommendations are published for all restricted medications to aid competitors, trainers, and veterinarians in maintaining compliance with the USEF's drug rules.
Forbidden medications and substances include those that may affect the cardiovascular, respiratory, or central nervous system or have a behavior-altering affect. This includes any stimulant, depressant, tranquilizer, local anesthetic, psychotropic substance, or drug that might affect the performance of a horse and/or pony, including corticosteroids and analgesics. Some forbidden medications may be used for legitimate emergency treatment if proper steps are taken.

ELCR Helps Horsemen Join Forces
Date: May 6, 2009
ELCR Helps Horsemen Join Forces with other Recreation Groups to Improve Trail Safety and Enjoyment of Public Lands
A group of national and state trail advocacy organizations representing equestrian, OHV, and bicycle interests recently completed a collaborative effort to develop a new guide called "Sharing Our Trails - A Guide to Trail Safety and Enjoyment". The guide is intended to be used in a variety of ways such as incorporation in trail brochures, magazine articles and trail education programs of all types.
The purpose of the guide is to improve safety and improve trail satisfaction for all trail enthusiasts on multiple-use trails. To quote the document itself, "In many parts of the country trails are open to and shared by equestrians , OHV riders, bicycle riders, runners and hikers. Trail sharing can and does work when people respect each other and work cooperatively to keep each other safe."
Deb Balliet, CEO of The Equestrian Land Conservation Resource stated "We all recognize that there are techniques and practices that will keep trail enthusiasts safe and improve the quality of our experiences. This guide represents the efforts of a broad range of trail enthusiasts working together to develop an understanding of each other's needs and develop a guide that specifically tells trail enthusiasts what steps to take when they meet on the trail".
Jack Terrell, Senior Project Coordinator for the National Off-Highway Vehicle Conservation Council said "Understanding other trail enthusiasts' needs, particularly when it comes to safety, is critical to minimizing conflicts and maximizing the enjoyment of all trail enthusiasts. This guide goes a long way toward promoting that understanding among everyone on the trail".
Daphne Green, Deputy Director of the California State Parks OHMVR Division stated "We are proud to work with the organizations involved in this effort to devise programs and initiatives to minimize user conflicts, increase safety, and enhance enjoyment of our public recreation opportunities".
Lori McCullough, Executive Director of Tread Lightly!, Inc. said "The Tread Lightly! ethic has always encouraged respect and courtesy between all trail enthusiasts, but conflicts still occur. This joint effort in educating all recreationists on the best practices for sharing trails shows common ground and collaboration can lead to improved trail experiences for all".
Jim Bedwell, Director of Recreation, Heritage and Volunteer Services for the US Forest Service stated "The groups that came together to produce the guide for sharing trails on our public lands are to be commended for their view of "the big picture." Outdoor recreation provides many benefits to people, communities, and the economy. An attitude of sharing increasingly scarce resources and cooperating safely is paramount to sustaining these benefits."
Tom Ward, California Policy Director for the International Mountain Bicycling Association (IMBA) said "This set of guidelines was developed after an extraordinary collaboration between equestrians, mountain bikers, hikers and motorized trail users. It includes suggested rules of etiquette, which provide understanding between users, and will create a safe and enjoyable experience for all. IMBA was pleased to be involved in this effort."
Organizations and agencies involved in the development of the guide include the American Endurance Ride Conference, Americans for Responsible Recreational Access, American Motorcyclist Association, American Trails, Back Country Horsemen of America, BlueRibbon Coalition, California State Parks Off-Highway Motor Vehicle Recreation Division, Cycle Conservation Club of Michigan, Equestrian Land Conservation Resource, International Mountain Bike Association, Leave No Trace Center for Outdoor Ethics, Loomis Basin Horsemen's Association, Motorcycle Industry Council, National Off-Highway Vehicle Conservation Council, Off-Road Business Association, Open Beaches- Trails, Recreational Off-Highway Vehicle Association, Specialty Vehicle Institute of America, Tread Lightly!, United Four Wheel Drive Associations, and United States Forest Service.

Equine Sarcoid Treatment Recommendations, WEVA 2008
Thehorse.com - Full Article
by: Stacey Oke, DVM, MSc
April 23 2009,
The equine sarcoid is an unpredictable skin tumor capable of wreaking havoc on a horse's body. While not technically a "cancer" (neoplasm) in the pathological sense, sarcoids are often considered as such because they are a potential career- and even life-ending condition.
"Even the most benign-looking small lesion can erupt into a potentially catastrophic mass in a short period of time," reported Derek Knottenbelt, OBE, BVM&S, Dipl. ECEIM, MRCVS, from the Philip Leverhulme Hospital at the University of Liverpool in the United Kingdom at the 10th International Congress of World Equine Veterinary Association.
Despite the availability of multiple surgical, medical, and even holistic/alternative therapies, the sarcoid remains a clinical challenge because:
* The cause of sarcoids remains undetermined;
* There are six distinct clinical types of sarcoids each with different presentations;
* Obtaining a definitive diagnosis via biopsy is not widely embraced because interfering with a sarcoid in any way can cause a massive and uncontrollable expansion of the lesion, and;
* A myriad of treatment options exist, yet the prognosis is always "very guarded" and serious complications can arise secondary to treatment.
