The accepted solution to this problem has been to find, during a pretrial period, a couple of sampling times in the diurnal pattern when the fecal concentration of [Cr.
Although these alkanes were dosed only once daily, Mayes et al (1986) observed relatively low diurnal variation in fecal concentration of [C.
Where F32 is the mean fecal concentration of even chain n-alkane after CRC dosed, [B.
32] are the herbage and fecal concentrations of the odd-chain ([C.
At the end of each experiment, fresh feces were collected from three randomly selected pigs in each pen to determine the fecal concentration of carbon dioxide and ammonia.
2006) found that fermented feed decreased the fecal concentration of ammonia of weanling pigs because the fermentation of protein was reduced in the gastrointestinal tract.
In our study of a wild herd of American plains bison (Bison bison), we hoped to determine whether environmental covariates could explain variations in the fecal concentrations
of corticosterone (CORT), thus elucidating spatiotemporal variations in the stress state of the herd.
At week 3, the fecal concentrations
of Lactobacillus and E.
If we eat uranium-rich algae (spirulina #3 and #4), as shown in Table 3, we can expect fecal concentrations
representing the uranium intake.
4) Although sex steroid hormone concentrations in excreta have been evaluated, (5-7) no studies have compared fecal concentrations
with blood levels or gonadal status.
The highest fecal concentrations
of virus were detected in 11 (69%) participants after their clinical signs had resolved.
of all the bacteria in the cocktail increased, compared with their basal levels in all patients.
