However the amount of oxygen expressed per unit surface is generally higher for debris than for oxidized activated carbons.
Intake of GE and metabolizable energy, and energy retained, all expressed per unit of metabolic body weight, did not differ among treatments.
In conclusion, in vitro CH4 measurement can be indicative of the trend of in vivo CH4 production from different combinations of sources and levels of starch when in vivo CH4 is expressed per unit eRFOM, but not when expressed per unit OM ingested.
Across the diets tested, 24-h in vitro CH4 (ml/g of incubated OM) correlated well with in vivo CH4 expressed per unit of eRFOM (R2 = 0.54; P=0.040), but not when expressed per unit of OM ingested (R2 = 0.04; P=0.878).
However, when expressed per unit of dry matter intake, folate DF and ARS were greater when cows were fed FS and they increased linearly with the proportion of UFA in the supplement.
Nutrient digestibility in the rumen, expressed in kilograms per day, was greater or tended to be greater for SDP cows, but differences were no longer significant when expressed per unit of nutrient ingested.
In comparison with 100% GS, CH4 production was 11 and 8% reduced for the 100% CS diet when expressed per unit of DM intake and per unit fat- and protein-corrected milk, respectively.
When the optimized CB FSB was used to treat synthetic aquaculture wastewater, with three bed expansions and four levels of C/N, total ammonia nitrogen removal rate expressed per unit of expanded bed volume was high, from 629 to 881 g m−3 day−1.
Results are expressed per unit surface area.
Then this difference can be expressed per unit cell or square unit area.
The enzyme activity was expressed per unit time per mg of protein.
