Answer:

In human nutrition, the glycemic index provides a physiological classification of foods useful in developing nutritional programs for patients with insulin resistance or noninsulin-dependent diabetes. Lacking effective application of glycemic response and glycemic index data of horse feeds, the focus has been instead on restricting starch and simple sugar intake in horses. There is currently a trend in the horse feed industry to manufacture low or controlled starch feeds, with claims of reducing the risk of grain-associated metabolic disorders; however, lack of reports elucidating the effect of various starch intakes on relevant outcomes leaves questions regarding exact concentrations of dietary starch for horses that may be considered “low.” Sufficient research supports limiting starch to no more than 2 g starch/kg BW/meal in order to avoid overload to the hind gut, but more research is needed to link minimum meal concentrations of starch for avoidance of other conditions that have been associated with dietary starch (e.g., gastric ulcer syndrome or equine metabolic syndrome). Recent work suggests that starch intake should be limited to <1 g starch/kg BW/meal in order to reduce risk of equine gastric ulcer syndrome (Luthersson et al 2009). An examination of glycemic and insulinemic responses to increasing starch intake of a mixed grain concentrate indicated that feeding <1.1 g starch/kg BW/meal resulted in lower glycemic and insulinemic responses, compared to meals up to 2 g starch/kg BW (Vervuert et al 2009b). A similar study in this laboratory examined glycemic responses to intakes of oat grain NSC (calculated as ESC + starch) ranging from 0.6 to 2.0 g/kg BW (Hoffman et al 2009). The glycemic response, calculated as the incremental area under the curve (AUC), plotted against NSC intake indicated a threshold of glycemic sensitivity (i.e. the inflection point, or knot) after which higher NSC intakes produced equally high AUC, at as little as 0.3 g NSC/kg BW/meal (Hoffman et al 2009).
