One of the classifications of carbohydrates comprising monosaccharide and disaccharide sugars which are digested by enzymes in the small intestine and once broken down and absorbed contribute to blood glucose. The ESC content is included in the Water Soluble Carbohydrate WSC fraction which also incorporates more complex oligosaccharides, polysaccharides and fructans. The ESC figure is thus always smaller than the WSC value on a feed label. It gives an indication of how much of a ‘’sugar hit’’ the feed packs.
