Fig. 3From: Diurnal variation of NMR based blood metabolites in calves fed a high plane of milk replacer: a pilot studyTwenty-four hour mean values (a, b) and mean baseline and 4-h postprandial concentrations (c, d) of blood metabolites in Holstein calves fed elevated plane of nutrition twice daily. Data are expressed as means ± SE. For each time point, * = significant difference at P < 0.05; ** = significant difference at P < 0.01Back to article page
