What can I give my horse to prevent tie-up?
Alternatively consider having your forage analysed, ideally choosing a low WSC hay over a low WSC haylage. Additional vitamin E and selenium may help to support muscle health and reduce the risk of tying up. Daily intakes of 1500-2500iu of vitamin E and 2-2.5mg of selenium have been suggested.
Which diets cause tying up in horses?
Diets high in starch and sugars (for example those that contain large amounts of grain based feeds) are well known to make tying up occur more frequently and severely. For horses with the PSSM form of tying up, we recommend that all feeds containing grains be removed from the diet completely.
What is the best diet for a thoroughbred horse?
RER Diet. This diet is for a 500 kg (1100 lb) thoroughbred in hard work. Note that cereal grains are providing less than 20 percent of this horse’s daily digestible energy requirement and that vegetable oils and high fat feeds like rice bran are supplying 24% of the horse’s daily digestible energy requirement.
How much vitamin E do you give a horse for tying up?
Adding vitamin E to the diet of horses prone to tying-up is also recommended to increase the muscle membrane integrity. Amounts up to 5,000 IU per day of vitamin E have been found to be effective at decreasing muscle enzyme leakage out of the cells.
What to feed horses prone to tying up?
So for horses prone to tying up use cooked grains like corn, barley and rice in place of oats. Tip 5 – Reduce or remove the grains or grain based feeds from the diet on days off. Horses fed their full ration on rest days seem to be more likely to be affected by tying up once they resume work.
How do I stop my horse from tying up?
Daily exercise is essential, either in the form of turnout, longing, or riding. Sometimes medications such as dantrolene given to fasted horses 90 min before exercise can be helpful in preventing anticipated episodes of tying-up. Another form of tying-up is polysaccharide storage myopathy (PSSM).
How long does it take for a horse to recover from tying up?
After an episode of tying-up, the muscle cells usually heal completely within three to four weeks without any scarring. If the damage is severe, you may notice that the horse's muscle mass decreases in size as the body removes the damaged proteins. The muscle mass usually returns within two to four months.
Can too much protein cause a horse to tie up?
Additionally, a horse that consumes too much protein will be at an even greater risk of contracting diseases and be predisposed to other symptoms such as hypothyroidism, tying up, kidney problems, and arthritis to name a few.
Can you give banamine to a horse that is tying up?
Non-steroidal anti-inflammatory drugs such as bute or banamine should be minimized as they impair kidney function. Lasix should never be used unless the horse is in renal failure and has IV fluids in place. There are specific medications such as Dantrolene that are effective in helping untie the muscle.
What causes muscle tying up in horses?
Polysaccharide storage myopathy (PSSM) has been identified to be the most common cause of tying up in Quarter Horses and Draft breeds (some specify the Draft horse disease EPSM). It is a primary muscle disorder characterized by the accumulation of unusable carbohydrate the muscle cells.
How do you stop lactic acid build up in horses?
Burning fat for fuel lowers lactic acid levels Fat, when used as an energy source (as compared to starches and protein), contributes to a decrease in lactic acid buildup in the muscle. Horses conditioned to use fat as energy have more stamina and recover faster after exercise.
How do you stop lactic acid build up?
Your body naturally gets rid of lactic acid through metabolism. Taking deep breaths, staying hydrated, and reducing exercise intensity are the best ways to maximize natural lactate clearance.

Why is it important to turn out horses with RER?
Turnout for horses with RER is beneficial, because it helps keep them moving, and being turned out with another compatible horse may help keep them calm. Days off should be kept to a minimum and, when possible, shouldn’t be consecutive.
Can horses eat low NSC?
Veterinarians recommend feeding PSSM horses diets low in NSC, because these carbohydrates have a direct impact on muscle glycogen; however, RER doesn’t affect muscle glycogen stores, so the reduced NSC is for a different reason. Horses with RER might tend toward excitability and tension, and high-NSC diets are more likely to cause these behaviors, ...
Do horses tie up when exercised?
However, when researchers increased calorie and high-starch concentrate intake, the horses became more likely to tie up.
What is a horse that ties up?
Horses and ponies prone to tying up can be broadly categorised into one of two types; those where susceptibility is linked to an underlying muscle condition such as Recurrent Exertional Rhabdomolysis (RER) or Polysaccharide Storage Myopathy (PSSM), and those who do not have an underlying muscle condition.

While waiting for the vet to arrive, make the horse more comfortable by removing tack, blanketing if it’s cold or providing shade if it’s hot, and holding up water for the horse to drink (he may not be able to lower his head to the ground). If possible, try not to move the horse.
What is RER in horses?
Recurrent Exertional Rhabdomyolysis (RER) is the term used to describe repeated episodes of tying up specifically due to an inherited abnormality with how calcium is regulated in muscle. This form of chronic tying up has been studied largely in Thoroughbreds, but has also been found in Standardbreds and Arabians.
What causes a horse to tie up?
Sporadic tying up is a temporary or occasional problem in muscle cells that may be caused by things like by fatigue, heat exhaustion, or electrolyte imbalance. It may occur in any age, breed, gender, or discipline and is not an inherited condition. Examples include a polo pony used in a match before he was fit enough to compete, a three-day eventer on an especially hot and humid day, or an endurance horse depleted of electrolytes after a 50-mile race.
Why do horses tie up?
For many years, tying up was thought to be the result of the build-up of lactic acid in muscles. However, due to advances in exercise physiology and muscle diagnostic testing, it has now been shown that lactic acid build-up in horses does not cause tying up. In fact, veterinarians and scientists now know that tying up is a syndrome ...

What is a horse tying up?
All of these horses have a form of tying-up. Researchers have classified the general disease known as tying-up into distinct syndromes. The definitions Recurrent exertional rhabdomyolysis (RER), polysaccharide storage myopathy (PSSM), and equine polysaccharide storage myopathy (EPSM) are common myopathies or muscle disorders.
How much starch should a horse eat daily?
At the very minimum, horses should receive at least 1% of their body weight in forage daily. One notable exception to this plan exists. Grain hays such as oat or barley hays should be avoided because high-starch grain kernels may be clinging to stems, and these will only serve to increase starch in the diet.
What is RER in horses?
RER appears to be an abnormality in muscle contraction brought about by excitement and exercise. This discovery was based on research that involved harvesting a sliver of muscle from between two ribs. The muscle was then evaluated to determine how it reacts in various conditions. Muscle from horses with RER reacted differently than muscle ...
Why does RER react differently to horses?
Muscle from horses with RER reacted differently than muscle from normal horses in that it was much more sensitive to contractions induced by certain agents. The contracture reaction indicated a possible problem with the way calcium is regulated inside the muscle cell.
How to know if a feed is low in starch?
If it is not clear whether a feed is low in starch and sugar, check out the ingredient list. It might reveal low-starch feedstuffs like soy hulls and beet pulp.
Do horses use glycogen?
Affected horses are able to use glycogen to fuel their muscles just as normal horses do. However, PSSM horses pull glucose from the bloodstream and deposit it into muscle tissue more quickly than normal horses, thereby creating more glycogen than normal horses.
Is grass hay good for horses?
Diets should be created in an effort to reduce starch intake and replace those calories with fat and fermentable fiber. Forage Good-quality grass or legume hay is acceptable for horses engaged in regular exercise. For those that are idle or perform minimal exercise occasionally, a clean grass hay is sufficient.
What causes a horse to tie up?
Once a horse has succumbed to an episode of tying-up, the chances are that they will be susceptible in the future. The following causes and solutions are relevant in maintaining bodyweight, yet reducing further attacks: 1 Dehydration and electrolyte imbalances — sodium deficiency is commonly found in diets of horses prone to tying-up. This affects the balance of electrolytes, which stimulate excessive calcium excretion, leading to inability to relax and contract muscles. It is therefore essential to provide electrolytes daily. Salt should be at the top of the ingredients list, ahead of glucose or dextrose. 2 Mineral and vitamin deficiencies — absorption rates can be affected by age. Provide a quality concentrate or broad-spectrum mineral and vitamin supplement containing high levels of antioxidants in chelated or bioplex form to assist the removal of free radicals. Many vets advise the addition of selenium and vitamin E supplementation to the diet. This is recommended if you are feeding large amounts of oil and will certainly aid recovery, but to prevent repetition of tying-up, the cause, not the symptoms, should be treated. 3 Hormonal fluctuation — this may be relevant to many mares, as it is believed that fluxes in the hormone oestrogen may influence specific minerals and vitamins as well as thyroid levels, all of which can trigger an attack. Susceptible mares can therefore succumb to an episode of tying-up at specific stages of their season. Apparently, chestnut mares are most prone.
What is azoturia in horses?
Azoturia. Nutrition plays an important role when trying to prevent tying up in horses, so here is a useful case study and sample diet from equine nutritionist Christ ine Smy for a horse that is susceptible to the condition, which is also known as azoturia.
How much fat should I feed my horse?
For a 1,000-pound horse, this is about two cups of oil (1 pound), or 5 pounds of a 20% fat feed, or 3.3 pounds of a 30% fat rice bran. Why fat? By replacing grain with fat, glycogen won't accumulate as easily.
What does it mean when a horse ties up?
Tying up in horses is characterized by muscle stiffness and pain, sweating, blowing, trembling, reluctance to move, and often discolored urine (brown) that's triggered by exercise. Tying up results when the energy supply to perform these functions is insufficient. The medical term for tying up is rhabdomyolysis-which means skeletal muscle (rhabdo) ...
What happens when a horse burns fat?
When a horse burns glucose or fat as a fuel, an inevitable end product is "free radicals," forms of oxygen that are very unstable.
How does a horse's body change?
During the process of properly conditioning/training a horse, his body goes through many changes. More blood vessels appear in the muscle, bringing the oxygen needed to efficiently generate energy. The muscle stores more energy in the form of fat around the muscle cells and glycogen directly inside the cells.
How to get a horse in shape?
Don't overwork your horse as you try to get him in shape. Supplement your horse's diet with vitamins and minerals, as needed. A horse on good hay with a salt source should be able to maintain mineral and electrolyte balance. Try to give fit horses exercise time, even on their days off.
Can horses have magnesium?
Horses vary quite a lot in how sensitive they are to low body levels of magnesium; that is, how likely they are to show symptoms. Some of this is just individual variation, some related to differences in other mineral levels in their diets. Either way, the point is that even though this is a nutritional issue, it's entirely possible to have only one horse in a group showing symptoms.
Can a horse be unfit to tie up?
Overworking an unfit horse may cause tying up, and so can underworking a fit one. Horses that are fit can be more prone to tying up if they spend one or two days confined to a stall, especially on a full grain feeding. This phenomenon has never been formally studied, but any trainer can tell you it's true.
