  1. 1MFI = mean fluorescence intensity
  2. 2T = treatment, S = sampling time, T × S = treatment × sampling time interactions.
  3. W = abruptly weaned, C = non-weaned (control) calves.
  4. a, b, cWithin a row, least squares means without a common superscript differ (P <0.05).
  5. x, yWithin a column (day) for each variable, least squares means without a common superscript differ (P <0.01). 2Baseline is defined as d 0 for each variable. Data presented are least squares means ± s.e.m.
