T = treatment, S = sampling time, T × S = treatment × sampling time interaction.

CS = concentrate supplement prior to abrupt weaning (n = 10). NCS = no concentrate supplement prior to abrupt weaning (n = 10).

¹Levels of significance: NS = P > 0.05, * = P < 0.05, ** = P < 0.01, *** = P < 0.001. ^{a, b, c}Within a row, least squares means without a common superscript differ (P <0.05).

²CD62L = L-selectin marker.

³Mean fluorescence intensity = MFI.
