title: [Proposal for an efficient crude fiber determination in routine analysis].
abstract: On the basis of the method described in the standard TGL 21875/07--method II in GDR--and proved effective in practise, a rationalised method of the determination of crude fibres has been worked out. This method is described in detail; it makes greater than 60 individual determinations of crude fibre per worker and day possible. In contrast to the conventional determination of crude fibres (standard 21875/07--method I) this method is more efficient and its degree of standardisation is considerably higher. The results achieved on the basis of the conventional method of the determination of crude fibres (standard TGL 21875/07--method I Lepper-method) and the suggested method of determination with various feedstuff samples at the Zentralstelle für Futtermittelprüfung und Fütterung (Central Institution for Feedstuff Investigation and Feeding) Halle-Lettin and Department of Animal Nutrition of the Forschungszentrum für Tierproduktion (Research Centre for Animal Production) Dummerstorf-Rostock show that there are no statistically significant differences between the crude fibre values ascertained according to the two methods. Method II of the standard TGL 21875/07 should be replaced by the suggested method of determination because this method directly registers the crude fibre content.
