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
Difference between dry matter and ash (mineral content).
