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

Seasonal and age-related variation in the needle quality of five conifer species.
TL;DR: It is suggested that the abundance of Lepidoptera on conifer is not determined by levels of general foliar constituents and the role of other hostplant factors in shaping lepidopteran utilization of conifers is discussed.

The effect of raw carrot on serum lipids and colon function.
TL;DR: Two hundred grams of raw carrot eaten at breakfast each day for 3 weeks significantly reduced serum cholesterol, increased fecal bile acid and fat excretion, and modestly increased stool weight, which suggests an associated change in bacterial flora or metabolism.

Leaf litterfall, fine-root production, and decomposition in shrublands with different canopy structure induced by grazing in the Patagonian Monte, Argentina
Analía Lorena Carrera,Analía Lorena Carrera,Mónica B. Bertiller,Mónica B. Bertiller,Cecilia Larreguy +4 more
TL;DR: Changes in canopy structure induced by grazing disturbance such as those explored in this study could reduce leaf litterfall mass and increase the concentration of secondary compounds of both leaf litter and fine roots leading to slow N release to soil during decay.

Organic waste treatment and C stabilization efficiency
TL;DR: In this paper, the stability of waste C was evaluated by determining mass losses of C during aerobic and anaerobic waste treatment and CO 2 evolution during decomposition in soil using materials of the same origin.

TL;DR: In this article, the authors used a free-air temperature enhancement (FATE) system in a controlled warming-grazing experiment in 2006 and 2007 to test the hypothesis that grazing modifies the response of soil solution DOC concentration to experimental warming.
