  1. T = treatment, S = sampling time, T × S = treatment × sampling time interaction.
  2. 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).
  3. 2PHA = Phytohaemagglutinin.
  4. 3ConA = Concanavalin A.
  5. CS = concentrate supplement prior to abrupt weaning (n = 10). NCS = no concentrate supplement prior to abrupt weaning (n = 10).
