Abstract Background It is unknown which metabolites are responsible for propylene glycol PG -induced toxicosis and a better understanding of the underlying mechanisms explaining incidences of abnormal behaviour of dairy cows fed PG is therefore needed. Methods The study included three cows of which one developed PG toxicosis. In order to investigate how the metabolism of PG differed in the cow developing toxicosis proton nuclear magnetic resonance NMR spectroscopy was applied on ruminal fluids and blood plasma samples obtained before and after feeding with PG. .
