Determination of Acid Detergent Fiber (ADF), Neutral Detergent Fiber (NDF), and Acid Detergent Lignin (ADL)

Acid detergent fiber (ADF) is a measurement of the content in cellulose, lignin, cutin and insoluble minerals in the cell wall and is determined as the residue remaining after degradation, for example, with an acid detergent solution consisting of diluted sulfuric acid and cetyl-trimethyl-ammonium bromide.

Neutral detergent fiber (NDF) is a measure of the total insoluble fiber found in a ration. The individual components that contribute to the neutral detergent fiber are hemicellulose, cellulose, lignin and some protein fractions. In feeds, NDF has a strong correlation with total organic matter digestibility and energy estimates. As feeds mature, the neutral detergent fiber value increases and digestibility decreases. This is the reason to ensure that only the highest quality roughage is given to lactating cows. In feeds, increased NDF values ​​are generally attributed to decreased dry matter intake.

A measure of the quality of feeds is the percentage of acid detergent fibers (ADF) and neutral detergent fibers (NDF) they contain. ADF and NDF levels are critical as they affect animal productivity and digestion.

Acid detergent fibers and neutral detergent fibers are important measures used in feed consumed by animals. The two calculations are based on the digestibility of plant material found in an animal's food. Farmers use these two calculations to determine how much food an animal needs and how much energy the animal will get from the food consumed.

Acid detergent lignin (ADL) is part of a sequential analysis developed to determine the digestibility and feed quality characteristics of feed samples such as alfalfa and various grasses. This analysis includes the gravimetric determination of neutral detergent fiber (NDF), acid detergent fiber (ADF), and ADL. NDF is a measure of the total cell wall content (cellulose, hemicellulose and lignin). Subtracting the ADF value from the NDF value results in an estimate of the hemicellulose content, while subtracting the ADL value from the ADF value results in an estimate of the cellulose content.

Determination of acid detergent fiber (ADF), neutral detergent fiber (NDF) and acid detergent lignin (ADL) with its trained and expert staff and advanced technological equipment, among the numerous test, measurement, analysis and evaluation studies it has given for businesses in various sectors. also provides services.
