Abstract
Almost a century has elapsed since Henneberg and Stohmann [1] proposed a method for the determination of "crude fibre" in feeding- stuffs. Their method, the so-called "Weende procedure", required feeding-stuffs to be digested for half an hour alternately with 1.25 per cent H2SO,. and 1.25 percent KOH. With certain well-known modifications, this procedure is perpetuated in the Fertilizers and Feeding-Stuffs Regulations as suitable for routine analysis but, because of modern investigations into the digestibility of crude fibre and the importance of this fraction in estimating starch equivalent values, improvements have been sought. In this paper two aspects of the suitability of the determination in its present form are described, in relation to "fodders" and to "concentrates".
