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

Urea ammoniation compared to urea supplementation as a method of improving the nutritive value of wheat straw for sheep
Swp Cloete,NM Kritzinger +1 more
TL;DR: Both ammoniation and urea supplementation of wheat straw significantly improved the apparent digestibility of CP as well as the N-balance, which was significantly reduced by 22,1 % compared to urea supplemented wheat straw.

CO2 emissions and mineral nitrogen dynamics following application to soil of undigested liquid cattle manure and digestates
TL;DR: In this paper, the authors carried out an incubation experiment to measure CO2 emissions and soil mineral N dynamics following addition to soil of: ammonium sulphate (AS); digested cattle slurry-maize mix (DSMM); LF and SF of DSMM; undigested cattle SLurry (US); and US and LF of US.
