What is the 5 panel test for horses?

What does a horse with PSSM look like?
Horses with PSSM can exhibit symptoms without exercise. During an episode, horses seem lazy, have a shifting lameness, tense up their abdomen, and develop tremors in their flank area. When horses stop moving they may stretch out as if to urinate.
Is alfalfa good for horses with PSSM?
Many PSSM horses tend to be easy keepers, making high-fat diets hard to feed without resulting in obesity. 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.
How do you prevent PSSM in horses?

Well-maintained pastures should contain low-sugar grasses and few legumes (clover, alfalfa or lucerne).

What kind of mutation causes PSSM in Quarter Horses?
