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.
