What is the difference between HYPP and PSSM?

Type 1 PSSM is a common cause for tie-up signs in Quarter Horses, Paints, Appaloosas, and warmbloods. PSSM can often be managed with diet and exercise changes but there is no cure or medication used to treat it. HYPP is an inherited muscle disease causing an abnormality in how muscle cells manage electrolytes.

What does a horse with PSSM look like?

The clinical signs of a PSSM episode are typically associated with tying-up. These signs are most commonly muscle stiffness, sweating, and reluctance to move. The signs are most often seen in horses when they are put into initial training or after a lay-up period when they receive little active exercise.

What is selenium good for in horses?

Selenium is required for equine muscle development and growth. Along with Vitamin E, it is a component of proteins that prevent muscle conditions such as tying up (nutritional myopathy or exertional rhabdomyolysis). This essential mineral is also important for reproductive health.
