Use of Detergents in the Analysis of Fibrous Feeds. I. Preparation of Fiber Residues of Low Nitrogen Content

Abstract Anionic, cationic, and nonionic detergents in different buffering media were examined for their capacity to dissolve nitrogenous constituents in forage dry matter, in the interest of preparing fiber of a low nitrogen content. Of the combinations examined, cetyl trimethyl ammonium bromide in strongly acid solution and sodium lauryl sulfate in slightly alkaline solutions appeared most effective.
