ABSTRACT
1H NMR spectra were acquired on plasma samples obtained from the mesenteric artery, hepatic
portal vein and the hepatic vein of steers (n=6) to demonstrate a NMR-based metabolomic approach
to study splanchnic metabolism. The metabolic differences between the different plasma samples
(arterial, portal, hepatic) were examined by partial least square regressions (PLSR) on the obtained
spectra. These analyses revealed spectral differences that could be ascribed to changes in the level
of propionate, β-hydroxybutyrate, lactate, acetate, n-butyrate and glucose, which was supported by
biochemical analyses.
