TL;DR: In addition to NDF, new improved methods for total dietary fiber and nonstarch polysaccharides including pectin and beta-glucans now are available and are also of interest in rumen fermentation.

TL;DR: In this paper, a new enzyme, Bacillus subtilis enzyme Type IIIA (XIA), has been proposed to replace the original XIA and has received AOAC approval and is rapidly displacing other amylases.
Abstract: There is a need to standardize the NDF procedure. Procedures have varied because of the use of different amylases in attempts to remove starch interference. 'Ihe original Bacillus subtilis enzyme Type IIIA (XIA) no longer is available and has been replaced by a less effective enzyme. For fiber work, a new enzyme' has received AOAC approval and is rapidly displacing other amylases in analytical work. This enzyme is available from Sigma (Number A3306, Sigma Chemical Co., St. Louis, MO). The original publications for NDF and ADF (43, 53) and the Agricultural Handbook 379 (14) are obsolete and of historical interest only. Up to date procedures should be followed. Tnethylene glycol has replaced 2-ethoxyethanol because of reported toxicity. Considerable development in regard to fiber methods has occurred over the past 5 yr because of a redefinition of dietary fiber for man and monogastric animals that includes lignin and all polysaccharides resistant to mammalian digestive enzymes. In addition to NDF, new improved methods for total dietary fiber and nonstarch polysaccharides including pectin and B-glucans now are available. The latter are also of interest in rumen fermentation. Unlike starch.

TL;DR: The apparent digestibility of 20 rendered animal protein ingredients from various origins was determined in three digestibility trials and Spray-dried blood products (whole blood, blood cells, blood plasma) were highly digestible (ADC protein=96-99%).

TL;DR: The relationship between plant genetics and silica metabolism is virtually uninvestigated, although reviews from plant physiology indicate it is a major factor in rice straw quality, which may contribute to higher straw value with rice yield.

TL;DR: Three double-marker systems were used to calculate duodenal flows of organic matter, non-ammonia N (NAN), microbial N and NDF, and the most suitable was AIA, followed by INDF6, INDF41 and IADF41, and ADL was the least acceptable marker.
