Feed Test Results: Acid Detergent Fibre (ADF)

ADF consists of cellulose, lignin, bound protein, and acid insoluble ash portions of a feed. Since these constituents are quite indigestible, ADF is a negative indicator of energy level in forages and grains, i.e., as ADF increases, digestible energy is decreased. Early-cut forages contain less ADF and a more energy than late-cut forages. Legumes generally have lower ADF and a higher net energy than grasses at comparable stages of maturity.
