Use of Detergents in the Analysis of Fibrous Feeds. II. A Rapid Method for the Determination of Fiber and Lignin
TLDR
The acid-detergent fiber method (ADF) as mentioned in this paper is a fiber method based on cetyl trimethylammonium bromide to dissolve proteins in acid solution.Abstract:
The capacity of cetyl trimethylammonium bromide to dissolve proteins in acid solution has been utilized in development of a method, called acid-detergent fiber method (ADF), which is not only a fiber determination in itself bnt also the major preparatory step in the determination of lignin. The entire procedure for determining fiber and lignin is considerably more rapid than presently published methods. Compositional studies show ADF to consist chiefly of lignin and polysaccharides. Correlations with the new fiber method and digestibility of 18 forages (r = —0.79) showed it to be somewhat superior to crude fiber (r = —0.73) in estimating nutritive valué. The correla-read more

Effects of Acomastylis rossii tannins on a mammalian herbivore, the North American pika, Ochotona princeps
TL;DR: Results demonstrate that although pikas constitutively produce salivary tannin-binding proteins, animals consuming a high-tannin diet of Acomastylis rossii exhibited lower dry matter, protein and fiber digestion and excreted higher concentrations of detoxification by-products.

Influence of level of maize cob meal on nutrient digestibility and nitrogen balance in Large White, Mukota and LW 〈 M F 1 crossbred pigs
TL;DR: In this paper, the authors compared the digestibility of organic matter (OM), neutral-detergent fiber (NDF), acid-Detergent fibre (ADF), hemicellulose and nitrogen (N) and N balance in Mukota (M), Large White (LW) and the LW × M F1 pigs.

TL;DR: It is demonstrated that the amount of added organic matter and macronutrients such as nitrogen and phosphorus, the biochemical organic compound classes (mostly soluble fraction and proteins), and the operational temperature are important factors affecting the overall efficiency of bioremediation.

TL;DR: In this paper, the fate of above-ground residue into soil organic matter (SOM) was tracked using isotopically labelled (13C and 15N) residue over 12 months in a pasture soil in sub-tropical Australia.

TL;DR: The depressive effects of sinigrin breakdown products on VFI were not compounded by the additional presence of DMDS which, on the contrary, lessened the depression of VFI caused by ACN.
