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

Moose Browsing on Scots Pine along a Gradient of Plant Productivity
TL;DR: Pines growing in unproductive habitats experience more damage by moose than those growing in more productive habitats, which suggests that trees in un productive habitats are qualitatively different, e.g., more palatable to moose, and/or less able to recover from browsing.

The effect of physiological state (lactating or dry) and sward surface height on grazing behaviour and intake by dairy cows
TL;DR: In this article, the effect of physiological state lactating vs. non-lactating (dry) on grazing behaviour and herbage intake by Holstein-Friesian cows was examined on grass pastures maintained at 5, 7 or 9 cm sward surface height (SSH), typical of those provided under continuous variable stocking management.

TL;DR: The white-rot fungi Ganoderma lucidum, Phanerochaete chrysosporium, Pleurotus ostreatus, P. pulmonarius and Trametes sp were used for biological pretreatment of Eucalyptus grandis sawdust as discussed by the authors.

Food selection by the silver leaf monkey,Trachypithecus auratus sondaicus, in relation to plant chemistry.
TL;DR: Differences in chemical measures for items eaten and not eaten were not statistically significant but trends indicate that leaves may have been selected for their lower fibre content and greater digestibility, and the role of tannins and phenolics in food selection is discussed.

How cellulose-based leaf toughness and lamina density contribute to long leaf lifespans of shade-tolerant species
Kaoru Kitajima,Kaoru Kitajima,Anna-Maria Llorens,Carla Stefanescu,Marta Vargas Timchenko,Peter W. Lucas,S. Joseph Wright +6 more
TL;DR: In this paper, the authors found that cellulose and lamina density jointly enhance leaf fracture toughness, and these carbon-based physical traits, rather than phenolic-based defence, explain species differences in herbivory, leaf lifespan and shade survival.
