The case has been made often regarding the futility of keeping crude fiber as anything but an index of historical appeal when it comes to define fiber quantity and quality in a feed or ingredient. Ruminant nutrition scientists have developed a new fiber system based on two better chemical analytical values, namely acid-detergent fiber (ADF) and neutral-detergent fiber (NDF), but it is of rare if any use for monogastric animals.
