Dietary management with PSSM in horses is very important to understand. Reducing the amount of starch and sugar in the diet of horse's with PSSM is the most effective way to stop episodes of tying-up. To do this -
Use low sugar, low starch forages as the base of the diet.
Do not feed any cereal grain or grain by-product (wheat, oats, barley, corn, rice, sorghum, triticale, rye, and by-products like pollard and bran)
Use additional oil and high energy fibres to add additional calories to the diet when needed.
Make sure all vitamin and mineral requirements are met, paying particular attention to selenium, vitamin E and the electrolyte minerals (sodium, chloride and potassium)
