Figure 7From: Proton nuclear magnetic resonance spectroscopy based investigation on propylene glycol toxicosis in a Holstein cow1H NMR spectra obtained on ruminal fluid samples obtained 0.5 h after feeding from the two control cows (a+b) and the cow responding abnormally to propylene glycol (PG) (c). The arrows indicate the signals that are lower in intensity in the cow responding abnormally to PG supplementation compared with the two control cows: 1: isopropanol/isobutyrate, 2: lactate, 3: acetate, 4: acetone, 5: citrate, 6: methyl acetate, 7: various smaller esters and alcohols.Back to article page
