Unpredictable Feeding Impairs Glucose Tolerance in Growing Lambs
Figure 2
Glucose and free fatty acid response to insulin tolerance test.
Plasma glucose (A,B) and free fatty acid (ffa)(C,D) concentrations during insulin tolerance test (ITT) before (A,C) and after (B,D) the six week dietary intervention in regularly fed (C) and unpredictably fed (U) sheep. Values are mean±SEM. ** p<0.01 for difference between C and U groups in the timing of nadir plasma glucose concentration. Time effect p<0.001, group × time interaction p<0.001; group effect p = 0.06 for plasma free fatty acid (ffa) concentrations after the intervention (D).
