Water soluble carbohydrates (WSC)
Water soluble carbohydrates are a summary of the ESC (sugars) and fructans causing the WSC content of the hay always be higher relative to the amount of sugar analysed within the hay. When hay is soaked in water, part of the WSC can be soaked out of the hay. This is why it is important to know the sugars as well as the WSC within the forage to know how much of the carbohydrates can be soaked out of the hay.
WSC is currently only analysed in hay samples.
