What is myositis horse?
Equine immune-mediated myositis (IMM) is a disease occurring in Quarter horses and QH-related breeds that typically causes rapid and severe symmetrical wasting of the topline muscles, often following exposure to or vaccination against respiratory infection by Streptococcus equi, the organism responsible for equine “ …
What is horse myopathy?
Myopathies are diseases that primarily cause damage to muscles. They may be present at birth (congenital) or occur due to nutritional imbalances, injury, or ingestion of a poisonous substance. Myositis is an inflammatory reaction in muscle.
How is IMM treated?
IMM is remarkably responsive to corticosteroids. Typical therapy consists of dexamethasone (0.05 mg/kg) for 3 days, followed by prednisolone (1 mg/kg for 7 to 10 days) tapered by 100 mg/week over 1 month.
What is Nonexertional rhabdomyolysis?
Nonexertional rhabdomyolysis, or “tying up not caused by exercise”, is characterized by severe muscle pain, stiffness and reluctance to move. Horses can lie down and have difficulty rising due to severe muscle pain.
What is PSSM1 in horses?
Polysaccharide storage myopathy (PSSM1) is characterized by the abnormal accumulation of the normal form of sugar stored in muscle (glycogen) as well as an abnormal form of sugar (amylase-resistant polysaccharide) in muscle tissue. By definition horses with PSSM1 have a distinctive genetic mutation in the gene.

What does it mean when a horse is losing muscle?

What causes muscle atrophy in an old horse?

What to do about muscle wasting in horses?
In addition to a well-rounded, fortified diet, supplementation with immune- and muscle-supporting nutrients may help horses with inflammaging and sarcopenia. Certain long-chain omega-3 fatty acids, specifically docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), reduce body-wide inflammation and strengthen the immune system.
