Animal feed

Near infrared reflectance spectroscopy (NIRS) anal

Agriculture; Animal feed

Rapid and low-cost computerised method to analyse forage and grain crops for their nutritive value. NIRS uses infrared light to determine protein, fibre, energy and mineral content.

Is metabolizable energy minus the heat increment of feeding. The net energy system divides energy requirements into net energy for maintenance (NEm) and net energy for growth (NEg) or net energy for ...

Net energy for growth (NEg)

Agriculture; Animal feed

An estimate of the energy value of a feed used for body tissue gain (weight gain) above that required for maintenance.

Net energy for lactation (NEL)

Agriculture; Animal feed

An estimate of the energy value of a feed used for maintenance plus milk production during lactation and for maintenance plus the last two months of gestation for dry, pregnant cows.

Net energy for maintenance (NEm)

Agriculture; Animal feed

An estimate of the energy value of a feed used to keep an animal in energy equilibrium, neither gaining weight nor losing weight.

Neutral detergent fibre (NDF)

Agriculture; Animal feed

Commonly called "cell walls". NDF gives a close estimate of fibre constituents of feedstuffs as it measures cellulose, hemi-cellulose, lignin, silica, tannins and cutins.
