What should you feed a horse with PSSM?
Forage and feed choices for PSSM horses are centered on minimizing sugar and starch intake. Forage requirements. Forage can be supplied as pasture, hay, or hay alternatives such as pellets or cubes. Well-maintained pastures should contain low-sugar grasses and few legumes (clover, alfalfa or lucerne).
What should a foundered horse not eat?
Horses that have foundered should eat hay. Do not feed oats, corn, or molasses. Your horse needs to be on low sugar, and low starch diet, and some senior feeds may fit the bill and be the right choice for horses prone to founder, but always read the label.
Can you feed alfalfa to a foundered horse?
Alfalfa hay can cause horses to founder and develop laminitis due to the excess nutrients provided by the high quality hay if too much is fed. If switching from grass hay to alfalfa, generally less alfalfa is required to provide the same nutrients present in the grass hay.
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.
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.
How do you stop lactic acid build up in horses?
In practice, administration of 50 mL of NEUTRADEX® in the feed daily, is helpful in preventing tying-up in some horses. NEUTRADEX contains an acid buffer which neutralises the lactic acid produced in muscles during hard or fast exercise.

These low-starch feeds should be fed with good-quality grass hay or a maximum of 50 percent alfalfa hay. Regular turnout for as much time as possible is critical to successful management of PSSM horses.
Is beet pulp good for PSSM horses?
To the contrary, beet pulp is very low in starch and sugar, usually containing only 2-10% total carbohydrates. Thus, it is a safe feedstuff for horses with metabolic concerns such as equine Cushing's syndrome, insulin resistance and polysaccharide storage myopathy (PSSM/EPSM).
Can you ride a horse with PSSM1?
Once conditioned, some PSSM1 horses thrive with 4 days of exercise as long as they receive daily turn out. For riding horses with type 2 PSSM1, a prolonged warm-up with adequate stretching is recommended.
How do I stop my horse from foundering?
To avoid grass founder:Allow the horse to fill up on hay before turning out on grass for a few hours.Place a grazing muzzle on horses predisposed to foundering to limit their forage intake. Grazing muzzles limit grass intake but allow the horse to exercise throughout the day.
How do you treat founder?
In horses that have developed founder due to dietary causes, it is advised to stop feeding all grain products and remove the horse from pasture. Some horses will require treatment with a nasogastric tube to remove excess feed from their gastrointestinal tract if they have overeaten.
Can you feed oats to a foundered horse?
There is increasing awareness that owners can safely feed whole oats to their horses due to the fact that the starch in oats is highly digestible. This starch is quickly broken down into sugars in the small intestines and is usually absorbed long before reaching the caecum.

What is a tie up in horses?
What is Tying Up? Equine Rhabdomyolysis (ERS) or ‘tying up’ is a condition that causes the muscles running over the hind quarters to tighten and cramp up. It may also be referred to as set-fast, Azoturia or Monday morning disease.
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.
What is a PSSM horse?
PSSM involves a defect in carbohydrate utilisation and/or storage in the muscle and commonly affects Quarter Horses and their crosses (Paints & Appaloosas), Draughts, Warmbloods and Morgans, although cases in Anglo-Arabs, Andalusians and Cobs have also been reported in the UK. Triggers include high starch/ cereal diets, ...
How long does it take for a horse to adjust to high oil?

What causes a person to tie up?
Triggers include under- exercising and over-feeding, electrolyte imbalances and low forage, high cereal/starch diets.
What to do when a horse is tied up?
When any exercise-induced tying-up episode occurs, the activity should be immediately stopped and the horse evaluated. Treatments can vary from case to case, depending on the cause, however general parameters for treatment include: Maintain hydration. Replenish electrolytes. Provide pain management.
What is the best supplement for horses?
Electrolytes, such as sodium, potassium, and calcium, are crucial for proper muscle function, and must be provided especially when a horse is sweating excessively and working hard. Adding vitamin E to the diet of horses prone to tying-up is also recommended to increase the muscle membrane integrity.
What is a tying up episode in horses?
Equine tying-up episodes can be categorized depending on the cause of the muscle damage: This fact sheet will focus on exertional rhabdomyolysis (ER). Exertional rhabdomyolysis refers to an episode of tying-up induced by activity and/or exercise. It has also been referred to as azoturia and “Monday Morning Sickness.”.
What is it called when a horse doesn't have the ability to use sugar?
This condition is called PSSM. PSSM can be classified into two categories, Type I and Type II.
What hormones are used to store glucose in horses?
Insulin is a hormone that allows the body to take the sugar (glucose) from dietary carbohydrates and store it in the form of glycogen for future use. Horses with PSSM have an enhanced ability for glucose storage into skeletal muscle, as well as a higher than normal sensitivity to insulin.
What happens when a horse is unable to move?
Typically occurs shortly after the onset of exercise or after exercise completion. Slight, sometimes unnoticeable cramping, or in more severe cases the horse may be reluctant to move. Lower back, gluteal, and thigh muscles become firm and painful. The gait becomes short and stiff.
What is it called when a horse has a muscle contraction?
This condition is called tying-up, or rhabdomyolysis, and is comparable to severe cramps that a human might experience. During these episodes, muscles become damaged and unable to function properly.
How to prevent a horse from tying up?
Consistent, calm exercise is an important part of preventing an episode of tying up in these horses.
How to make a horse comfortable?
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 is a chronic tying up?
Chronic Tying Up. On the other hand, “Chronic Tying Up” is an internal problem with the muscle tissue itself. It may still be triggered by exercise and affected by diet, management, and other factors. However, with this form of tying up there is some underlying defect in muscle structure or function causing horses to have repeated episodes.
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 ...

With vet guidance, the horse may be put into a stall or other confined area since the horse should move as little as possible for the next 24 - 48 hours.
What does it mean when a horse is tied up?
An acute episode of tying up, which often begins within 20 minutes of light exercise, is characterized by reluctance to move, tucked-up abdomen, quivering in the flank, significant sweating and muscle stiffness. Hindquarters are most often affected but the back, abdomen and forelimbs may also be involved. Horses will have markedly elevated serum ...
How much glycogen does a horse have?
Muscle biopsy studies from Dr. Stephanie Valberg in 1992 revealed that horses affected with PSSM store 1.5 to 4 times the muscle glycogen as normal horses.
What is genetic mutation in horses?
Valberg and supported by the American Quarter Horse Association (AQHA), found a genetic mutation was responsible for the abnormal polysaccharide in type 1 PSSM horses. A genetic test is commercially available through the University ...
How long can a horse stay asymptomatic?
Since this is less invasive than the muscle biopsy, many horse owners opt for the genetic testing. PSSM horses can remain asymptomatic for years (average age of first appearance of symptoms is 6 years) until there is some change in their schedule, such as being laid off due to injury or not getting regular exercise due to weather.
What is PSSM in horses?
PSSM and Horse Tying Up: A Matter of Genetics, Exercise and Nutrition. Polysaccharide storage myopathy (PSSM) was first identified in 1992 as one of the causes of exertional rhabdomyolysis (ER) in horses, which is muscle damage from exercise, commonly known as tying up.
Why do horses have Monday morning disease?
The term “Monday Morning Disease” was coined due to the frequency of symptoms appearing in working draft and carriage horses on the Monday following a weekend of rest, while consuming a full ration of oats or sweet feed.
What color is a horse's urine?
Horses will have markedly elevated serum creatine kinase (CK) of more than 35,000 U/L and may have myoglobin in the urine, giving it a reddish-brown color .
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.

Tying up is a painful condition for a horse and a frustrating one for you as an owner.
What is tying up?
Tying up, also called ‘exertional rhabdomyolysis’ is a group of diseases that cause muscle damage and pain during and immediately following exercise.
Dietary management of horses with tying up
Both forms of tying up benefit from close dietary management. Following are five rules you should follow to formulate diets for horses that tie-up:
Combine good feeding with good management
A well balanced diet containing the right amount of energy from fibre, starch and oil with all requirements for vitamins and minerals being met is only part of the puzzle for effectively managing both PSSM and RER forms of tying up.
Avoiding the knots
Following good dietary management by minimising sugar and starch intake, providing 13 to 25% of daily energy intakes as oil or high fat feeds, meeting all essential vitamin and mineral requirements including those for electrolytes and antioxidants and providing a regular exercise routine that remains within the horse’s level of fitness will all help to keep your tying up prone horses muscles ...
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.
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.
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.
What does it mean when a muscle is tying up?
Blood tests will show elevated levels of muscle enzymes. Tying up is best described as an energy crisis in the muscle cell. It takes energy for the muscle to contract. However, it also takes energy for the muscle cell to be able to release the contraction.
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.
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) ...
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.
What should be included in a horse's diet to prevent tying up?
The diet should be adjusted to include a balanced vitamin and mineral supplement, high-quality hay, and a minimum of carbohydrates (such as grain and sweet feed).
What is the best medicine for horses to avoid tying up?
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). It is characterized by the accumulation of glycogen (storage form of sugar) and an abnormal sugar (polysaccharide) ...
What type of horse has PSSM?
Type 1 PSSM occurs in many Quarter Horses and related breeds, draft breeds, some warmblood breeds and several other breeds as well. It has not been identified in Thoroughbreds to date. This mutation causes PSSM horse’s muscle to continually make glycogen.
Why do horses get sore after exercise?
Affected horses develop stiffness, muscle cramping and soreness with light exercise probably due to a deficit of energy generation in their muscles . Some horses with this disorder also have an increased sensitivity to insulin further increasing storage of sugar (glycogen) in the muscle.
Why do horses tie up?
Some horses are healthy athletes that tie-up sporadically likely due to exercise in excess of their training level, electrolyte depletion, or dietary imbalances. They respond well to rest, a gradual return to a graduated training regime, and balancing the diet. Other horses will suffer from chronic episodes of tying-up that can be debilitating.
Is tying up a disease?
In other words, tying-up is not one disease, but several different diseases that have similar signs and different causes. Therefore, the management of a Thoroughbred that suffers from tying-up would differ from the management of a Quarter Horse that is tying-up, would differ from the management of a backyard pleasure horse ...
Is there a cure for tying up?
Since there are several causes, some of which appear to be inherited, there is no single cure. Typical signs of tying-up include a horse which becomes stiff, sweats, and is reluctant to move. Researchers have learned a great deal about tying-up—or exertional rhabdomyolysis—in recent years.
