Frequency of lying bouts decreased (estimate = −1.90 ± 0.63 bouts/d) and average bout duration increased (estimate = 15.44 ± 3.02 min) with the use of deep bedding.
In the NE, daily lying time increased with the use of deep bedding (estimate = 0.80 ± 0.31 h/d) and as average days in milk (DIM) of the focal cows increased (estimate = 0.08 ± 0.04 h/d for a 10-d increase in DIM).
These observations explain the initial increase of deep bed filtration efficiency and the following monotonic decrease.
The percentage of patients with head bed position > 30° (49% vs 77%, P < 0.001) and the use of deep vein thrombosis prophylaxis (61% vs 82%, P < 0.001) increased after the use of the checklist during the rounds.
The final multivariable model, which explained 36% of the variation in severe hock injuries, included the use of automatic scrapers and deep bedding.
This case was produced by the prolonged heating of wrought iron packed in a deep bed of glowing charcoal.
A trickling filter is simply a tank filled with a deep bed of stones.
Generally, for people experiencing difficulties with sleep, spending less time in bed results in deeper and more continuous sleep, so clinicians will frequently recommend eliminating use of the bed for any activities except sleep (or sex).
Deep bed filtration of suspension in a porous medium is considered.
This article presents a comprehensive review of the literature related to deep bed filtration theories.
