Get an overview of new global standard methods for determination of detergent fibers aNDF, ADF and ADL
Feed value and ration calculations have traditionally been based on chemical composition data including crude fiber (Weende method).
In recent years, new models for the calculation of feed values including detergent fiber have found a wider application. Learn more about these methods via a complimentary 30 minute webinar to be held by Dr. Jürgen Möller, Senior Chemist/Regulatory Affairs on 28th January 2010. Two sessions will be held: 0900 CET and 1600 CET. Click on the relevant time for registration.
Topics to be discussed include:
- Crude fiber (CF) determination and its limitations
- Amylase treated neutral detergent fiber determination (aNDF)
- Acid detergent fiber determination (ADF) and
- Lignin (ADL) determination

An article describing a FOSS-pioneered standard for analysis of fibre in feedstuffs has been published in the Journal of AOAC INTERNATIONAL.
The article entitled ‘Gravimetric Determination of Acid Detergent Fibre (ADF) and Lignin (ADL) in Feed: Interlaboratory Study’ has been written by Dr Jürgen Möller of FOSS. It describes the method behind the new global standard for ADF and ADL that has recently been approved by CEN and ISO (EN ISO 13906:2008).

The standard method described in the article is based on the AOAC Official Method 973.18. It will enable official bodies to require fibre guarantees on livestock feed labels and allow international trade on basis of a harmonised protocol.
The standard is also important for the ISO 17025 accreditation of laboratories using the FOSS Fibertec™ system and for the development of NIR prediction models. Laboratories no longer need to worry about the validity of their methods - by following the standard, the results will be valid worldwide. The Fibertec instrument is an optimal solution and was used at 18 of the 22 laboratories involved in the inter-laboratory study behind the new standard.
