Oral fluid samples were collected in 9 weekly samplings from all pens in 3 barns on one production site beginning shortly after placement of weaned pigs.
Tear fluid samples were collected between 9 am and 4 pm, with no statistically significant differences in collection times between control and keratoconus subjects.
Six fluid samples were collected from various reservoirs in the Middle East.
Fluid samples were collected from 20 sampling ports to determine dissolved TCE concentrations.
Ruminal fluid samples were collected through the cannula at 0, 2, 4, 6, and 8 h after feeding.
Study Design: Amniochorion and amniotic fluid samples were collected from gestational age matched groups of women undergoing cesarean delivery before term.
During wk 12 and 16, rumen fluid samples were collected via esophageal tubing for pH, ammonia N, and volatile fatty acid analyses.
Milk production and composition were measured twice daily from d 11 to 21 of each period, and rumen fluid samples were collected on d 21.
Rumen fluid samples were collected to determine pH, volatile fatty acids, and NH3 concentrations, and Co-EDTA was used to determine fractional liquid passage rate.
Rumen fluid samples were collected at 3 h post feeding and the cell populations were calculated for the same, since a 3 h post feed would allow sufficient cell proliferations and adherence of few species on feed particles and microbes.
Apparent digestibility, lactation performance, N and energy balance, and CH4 emission were measured in climate respiration chambers, and rumen fluid samples were collected using the oral stomach tube technique.
