From: Differences in host breed and diet influence colonization by Campylobacter jejuni and induction of local immune responses in chicken

  1. BT and LT, which were fed with either bf or lf, were orally inoculated with approximately 104 CFU of C. jejuni at 1 (Experiment 1) or 22 (Experiment 2) dph
  2. BT broiler-type birds and LT layer-type bird fed with either bf  broiler feed or lf layer feed, CFU colony forming units, dpi days post inoculation, dph days post hatch
  3. abDifferent superscript letters indicate significant differences between groups of the same age at the indicated days post C. jejuni inoculation (n = 6/group, p < 0.05)
