With the application "Crude fiber determination in animal feed" and the automatic fibre extractor FIBRETHERM, feed laboratories can determine the crude fibre content reliably and standardised.
The crude protein content is obtained by multiplying total nitrogen by 6.25. Crude fibre “Weende” methods, based on acid hydrolysis followed by alkaline hydrolysis, such as AFNOR NF V03-40 (1993). Crude fibre is a default estimate of the cell wall content, which is actually 2 to 4 times higher.
sample – moisture – Crude Protein – Crude Fat. In addition, Crude Fibre determination by acid hydrolysis with 1,25% H 2 SO 4 is used for the extraction of sugars and starch, followed by alkaline hydrolysis with 1,25% NaOH, which removes proteins and some hemicellulose and lignin (fig. 1). Crude Fibre is commonly used to estimate • History:
determine the nutrient content of a mixed feed or a particu lar ration component. decrease feed costs through lower-cost rations and more efficient utilization. evaluate forage production practices such as plant species selections, fertilizer schedules, and time of harvest (age of regrowth)
The FIWE Series is suitable for Crude Fiber (CF) determination and fiber fractions. Benefits of FIWE Advance are: • 6 positions simultaneously and unsupervised
Crude fibre, also known as Weende cellulose, is the insoluble residue of an acid hydrolysis followed by an alkaline one. This residue contains true cellulose and insoluble lignin. It is also used to assess hair, hoof or feather residues in animal byproducts.
24 lip 2012 · Crude fiber always underestimates the actual fiber content of a forage, and while the crude fiber measurement must appear on labels, it is not a number that is particularly helpful in understanding the analysis of a horse feed.
