The results from Sar et al (2004b) are so different to previous results reported from that
group that it could be that the units on the graphs reported in the paper may be in error. If the
values for rumen nitrate and nitrite concentrations (μg/ml) were actually nitrate-N and nitrite-N,
then the peak nitrate would be 9.3 mmol/L and peak nitrite 2.0 mmol/L and the results would then
fit with their other studies in sheep not acclimated to nitrate.
