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

Use of principal component analysis to assess factors controlling net N mineralization in deciduous and coniferous forest soils
TL;DR: In this paper, the authors investigated the relationship between the net N mineralization rate and the initial mineral N content in three different forest sites (Belgium): a mixed deciduous forest with oak (Quercus robur L. and Quercus rubra L.) and birch (Betula pendula Roth) as dominant species, a decidable stand of silver birch and a coniferous stand of Corsican pine (Pinus nigra ssp. Laricio).

Interaction of position, litter type, and water pulses on decomposition of grasses from the semiarid Patagonian steppe
TL;DR: The results of this mesocosm experiment support the idea that controls other than water availability may dominate aboveground mass loss, while a combination of recalcitrant litter and water penetration in the soil profile are critical factors determining belowground decomposition, which is ultimately mediated by biotic degradation.

Resistance of leaf and stem fractions of tropical forage to chewing and passage in cattle.
TL;DR: It was concluded that VI of tropical forages was associated with the resistance of LP to breakdown by chewing during both eating and rumination and that the patterns of escape of small particles from the reticulo-rumen were only partially explicable in terms of particle dimensions, and that other properties of the particles may be of importance.

The study of several modifications of the neutral detergent fibre procedure
TL;DR: In this paper, eight modifications of the original procedure for the determination of neutral detergent fibre (NDF) in feeds were compared and two modifications yielded NDF values that were not significantly different from the original method.

Intake, by sheep, and digestibility of chickweed, dandelion, dock, ribwort and spurrey, compared with perennial ryegrass
TL;DR: The true dry matter digestibility of chickweed, dandelion, dock and leafy ribwort was as high as that of ryegrass, but the in vivo Digestibility of all five dicotyledonous species was higher than might have been predicted from their digestibility.
