Name | Definition |
---|---|
OM |
Organic matter. Difference between dry matter and ash (mineral content). |
OM digestibility, pepsin |
Organic matter digestibility estimated by an in vitro method using pepsin, such as the one developed by Tilley and Terry (1963), which involves rumen liquor and pepsin. |
OM digestibility, pepsin-cellulase |
Organic matter digestibility estimated by an in vitro method combining pepsin and a cellulase enzyme. |
OM digestibility, ruminants |
Organic matter digestibility for ruminants, calculated as percentage of digestible (total tract) organic matter in the organic matter of the feed. |
OM digestibility, ruminants (gas production) |
Organic matter digestibility for ruminants estimated from the volume of gas produced after 24 hour of incubation (GP, ml/200mg DM) and the proportion of crude protein (CP, % DM) as established by Menke and Steingass (1988): OMD (%) = 24.91 + 0.72222 GP + 0.0815 CP |
Organic matter |
Difference between dry matter and ash (mineral content). |
Oxalate |
Oxalate, salt of oxalic acid, found in many plants. Oxalate crystals may cause problems, either by mechanical action or because they retain calcium in a non available form. |
