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

Sunlight Doubles Aboveground Carbon Loss in a Seasonally Dry Woodland in Patagonia.
TL;DR: It is demonstrated that direct photodegradation and its legacy, associated with increased microbial access to labile carbohydrates, are responsible for the acceleration of aboveground C turnover in this Mediterranean-type climate.

Effect of monensin on gain and forage utilization by calves grazing Bermudagrass.
TL;DR: The use of 200 mg monensin/head/day improved calf gains by 23 to 45% and increased estimated feed efficiencies by 21 to 36% on Bermudagrass pastures.

Characterizing lignin: Combining lignin phenol, methoxy quantification, and dual stable carbon and hydrogen isotopic techniques
TL;DR: In this paper, the Zeisel method was used to cleave the ether bonds with hydroiodic acid to yield iodomethane which can be analyzed by gas chromatography (GC).

High CO2 effects on postharvest biochemical and textural properties of white asparagus (Asparagus officinalis L.) spears
TL;DR: In this article, the effects of high CO 2 concentration (10% CO 2, 17% O 2 ) on the changes of functional cell wall components (pectic substances, hemicellulose, cellulose, lignin), mechanical properties, content of free soluble sugars (sucrose, glucose, fructose), and respiration activity were studied in harvested white asparagus spears stored at 10 and 20°C.

Continuous in-house acidification affecting animal slurry composition.
TL;DR: In this paper, a full-scale study was performed, comparing pig slurry from normal in-house slurry management with acidification from housing with daily inhouse acidification to pH 5.5.
