The percentage of starch and ESC (Ethanol Soluble Carbohydrates) are the measurements I use to evaluate the non-structural carbohydrates in a feed. NSC is mathematically calculated from the following: %NSC = 100 – (moisture + NDF + CP + Fat + Ash) and thus is an indirect empirical (mathematical) determination. The empirical score that one sees as % NSC has variables and inconsistencies when comparing feedstuffs. The Integrity Adult/Senior (No Molasses) contains 5.5% starch and 5.9% ESC. Integrity Lite – No Molasses contains 1.6% starch and 5.9% ESC. Integrity Timothy contains 13.2% starch and 7.4% ESC.
