Experiment 2.1: GC-MS results showing carvacrol concentrations (µM) in amniotic fluid (A), blood (B), and yolk (C) at 9 h after in ovo injection of oregano essential oil (OEO) in combination with polysorbate 80 (p80) at 4 different ratios (ratio p80:OEO 0:0, 0:1, 0.5:1, and 1:1, n = 6 per ratio), injected into the amniotic fluid on incubation d 17.5 (LSmeans ± SEM).
a-cLSmeans within a tissue lacking a common letter differ (P ≤ 0.001).
