Figure 1.
Incidence and relative abundance of bacterial strains given on day of hatch in chicken samples collected on d 2, 7, and 17. Experiment 1 done in broilers (A), experiment 2 in layers (B). For each treatment incidence is shown on the left while relative abundance is shown on the right. Levels in exposed chicks shown in red, in non-exposed control chicks shown in blue. In experiment 1 n = 5 for all groups except for P. salanitronis Yara001 in the cecum, P. plebeius Yara004 in the jejunum, and R. torques Yara008 in the jejunum in which n = 4, and P. salanitronis Yara001 in the jejunum in which n = 2. In experiment 2, n = 6 for all except for L. salivarius Yara018 for which n = 5 in both cecum and jejunum. Statistical analysis was done by using t test in JMP 16 and GraphPad Prism 6. Results are presented as Mean ± SD. * 0.01 ≤ P <0.05, ** 0.001 ≤ P < 0.01, *** P < 0.001, **** P < 0.0001.
