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

1Levels of significance: NS = P > 0.05. * = P < 0.05. a, bWithin a row, least squares means without a common superscript differ (P <0.05).

2PHA = Phytohaemagglutinin.

3ConA = Concanavalin A.

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