Tying up or myositis

What is myositis ? 

Myositis, also commonly known as Tying up or Monday morning disease, is a disease that destroys the horse’s skeletal striated muscles. Its symptom is generalised cramps which are very painful for the horse. It can appear sporadically (for example during or following strenuous exertion or following a stressful situation) or recurringly. Myositis can also be a chronic genetic disease called RER or PSSM (type I and type II). RER (Recurrent Stress Rhabdomyolysis) is linked to a lack of calcium regulation in muscle cells while PSSM (Polysaccharide Storage Myopathy) is linked to an energy storage problem in muscle cells.

What should you feed a horse with myositis ?

Good diet management can be effective in preventing a resurgence of PSSM. Since this disease is linked to poor energy absorption, the horse’s diet should minimise the supply of glucose in the blood, as its metabolism converts it into polysaccharides (which cannot be used to respond to exertion). A low starch (contained in cereals) and carbohydrate horse feed is therefore strongly recommended. The ideal ration for your horse should be high in fibre (almost exclusively fodder, if possible) and fat. It is also very important to reduce the ration when the horse is not working or is recovering from an injury or illness. H150 horse feed (fibres and pellets) is suitable for horses with myositis. It is not only low in starch, it also contains antioxidants as well as pre-biotics and probiotics to promote intestinal transit.

What feed supplements can you give to a horse with myositis ?

In order to protect the horse’s muscle cells against oxidative stress, vitamin E and selenium-based feed supplements may be recommended for your horse.

You can add them to its ration to boost its metabolism for proper muscle mass functioning and better recovery after exercise. C600 horse feed supplement improves the cardiac function of the horse and eliminates toxins, such as CPK and AST, thanks to the omega 3 and antioxidants it contains.

What other factors should be taken into account to prevent myositis ?

In addition to proper management of the horse’s diet (adjusting the ration and avoiding overeating), there are other things that can help your horse, such as a calm environment (myositis can be triggered by stress in some cases) and regular and progressive training (resting in stalls is to be avoided).
