Effect of diet treatment on whole blood glucose and serum insulin. a Glucose levels in each diet treatment group (ABX, COC, and NABX) over time. b Change in glucose levels in response to diet over time. c Insulin levels in each diet treatment group (ABX, COC, and NABX) over time. d Change in insulin levels in response to diet over time. Values for the change in glucose or insulin were normalized to individual animal baseline (d24) measurements and then averaged across treatment groups for each age (d31, d45, d71). Within diet treatment but between age, points or bars with different lowercase letters have significant differences between ages within a diet treatment (P ≤ 0.05). Within age but between diet treatment, brackets with: * denotes significant differences between diet treatments at P ≤ 0.05; ** denotes significant differences between diet treatments at P ≤ 0.01
