Dietary peNDF content was determined from the sum of the proportion (dry matter basis) of dietary dry matter retained either on the 2 screens (8- and 19-mm) or on the 3 screens (1.18-, 8-, and 19-mm) of the Penn State Particle Separator multiplied by the neutral detergent fiber content of the diet.
The peNDF contents were determined by multiplying the proportion (dry matter basis) of feed retained on the 2 screens (8 and 19 mm) of the Penn State Particle Separator by the NDF content of the diet, and were 10.5, 11.8, and 13.8% for the low, medium, and high diets, respectively.
After this procedure, the samples were treated with ethanol/water in 1 1 (v/v) proportion, dried in a stream of nitrogen gas, and baked for 15 min at 110°C in order to dry completely.
Pearson Chi-square tests were performed to assess the univariate relationships between management systems and the following variables; parity distributions, proportion dried off quarters, AI versus natural mating, season for first AI, proportion of milk samples negative for pathogens, and proportion of milk samples from clinical mastitis negative for pathogens.
In operation, the process involves the proportioning, drying, and mixing of the lead-bearing materials and fluxes, followed by their injection into the reaction shaft, where they are ignited by a heated blast of commercially pure oxygen.
Combined effects of single-gene mutations (G), harvest stage (HS) and sample drying technique (DT) on the proportion of dry matter (DM) and starch degraded ruminally in situ and post-ruminally in vitro were evaluated using four near-isogenic lines in Oh43 inbred background: floury-2 (fl2), opaque-2 (o2), sugary-2 (su2), waxy-1 (wx1) genes and normal Oh43.
Through optimisation of the foam column operating conditions the proportion of dry matter retained in the fermenter was increased from 88%to95%5%, in contrast to dry matter retention of 66% for fermentation without the new design.
Increasing the proportion of dry hay increased sorting.
The whole aqueous biomass was transferred onto the IR dryer, and water was evaporated by infrared radiation to estimate the proportion of dry biomass.
The cyanobacteria typically accumulated a narrower range of FAMEs that were mostly saturated, but were capable of accumulating a larger quantity of lipid as a proportion of dry weight (M. laminosus, 37.8% fully saturated FAMEs).
On the other hand, increasing the forage particle size in a diet containing a high amount of concentrate increased the proportion of dry matter retained on a 1.18-mm screen from 37.5 to 42.0% and extended the rumination time by 100 min/d, as well as increasing the ruminal mat consistency.
