Name Definition
a (DM)

Immediately degradable dry matter fraction (%) in the model of ruminal degradation y = a+b (1-e-ct) (Ørskov and MacDonald, 1979).

a (N)

Immediately degradable nitrogen (N) fraction (%) in the model of ruminal degradation y = a+b (1-e-ct) (Ørskov and MacDonald, 1979).

ADF

Acid Detergent Fiber, fraction of the cell walls according to Van Soest, considered to be roughly equivalent to true cellulose and lignin.

Alanine

Amino acid. Often abbreviated ALA.

AME poultry

Apparent metabolizable energy, poultry. Difference between the gross energy in the feed and the gross energy in the droppings and gasses, not corrected for nitrogen retention.

AMEn broiler

Apparent metabolizable energy, nitrogen-corrected, for broilers.

AMEn broiler, ground

Apparent metabolizable energy, nitrogen-corrected, for broilers fed ground feed.

AMEn broiler, pelleted

Apparent metabolizable energy, nitrogen-corrected, for broilers fed pelleted feed.

AMEn cockerel

Apparent metabolizable energy, nitrogen-corrected, for cockerels.

AMEn cockerel, ground

Apparent metabolizable energy, nitrogen-corrected, for cockerels fed ground feed.

AMEn cockerel, pelleted

Apparent metabolizable energy, nitrogen-corrected, for cockerels fed pelleted feed.

AMEn poultry

Apparent metabolizable energy, N-corrected, poultry. Difference between the gross energy in the feed and the gross energy in the faeces, urines and gasses, corrected for a nitrogen balance of 0.

Arginine

Amino acid. Often abbreviated as ARG.

Ash

Ash remaining after incineration, a rough approximation of mineral matter.

Aspartic acid

Amino acid. Often abbreviated ASP.
