Certain horses do best on low sugar (ESC) & starch grains / concentrates, such as those with metabolic concerns, ulcers, PSSM etc. Horses with metabolic conditions should strive for feeds with combined sugar and starch under 10%. For these horses, owners turn to feed companies to help provide them with safe options. Almost every grain company offers a low sugar and starch option. Some may market them as “Low Carb”, “Low Starch”, or simply “Safe”. Can owners rely on the information printed on the front of these bags? The sad answer is No.
