Effect of abrupt weaning at housing on percentage a) CD4+ and b) CD8+ lymphocytes (least squares mean ± s.e.m., %) and c) CD4: CD8 ratio (least squares means ± SEM) in beef calves. W = abruptly weaned calves, C = non-weaned (control) calves. a, b, cBetween days, least squares means without a common superscript differ (P <0.05). x, yWithin a day, least squares means without a common superscript differ (P <0.05). T × S = treatment × sampling time point interaction. Baseline is defined as d 0 for each variable.
