  1. a: IBW Inoculation before weaning, IDW Inoculation during weaning
  2. b: Body weight before euthanization
  3. c: Lambs from same triplets were considered as blocks factor
  4. d: Values with different letters within a row were significantly (or significant trend) different according to pairwise comparison
