Figure 2From: Metabolomic changes in polyunsaturated fatty acids and eicosanoids as diagnostic biomarkers in Mycobacterium avium ssp. paratuberculosis (MAP)-inoculated Holstein–Friesian heifersHCA of significant metabolite changes in serum differentiating between MAP-inoculated and control heifer calves. Heifer calves were aged between 1-month and 19-months of age. Major patterns of metabolite accumulation during the experiment are indicated by the numbered clades (1,2,3 and 4).Back to article page
