  • Authorities of almost all countries require manufacturers of food & feed products to declare the fiber content as part of the nutritional table
  • Weende Method
    The oldest analytical procedure still in use today, in which fiber concentration is measured as crude fiber (CF)
  • Neutral Detergent Fiber (NDF) Method
    A method developed by Van Soest, being now the most common measure of fiber used for animal feed analysis
