Effect of abrupt weaning at housing on a) WC1⁺ and b) MHC Class II⁺ lymphocytes (least squares mean ± s.e.m., %) in beef calves. W = abruptly weaned calves, C = non-weaned (control) calves. ^{a, b, c}Between days, least squares means without a common superscript differ (P <0.001). ^{x, y}Within a day, least squares means without a common superscript differ (P <0.01). T × S = treatment × sampling time point interaction. Baseline is defined as d 0 for each variable.
