  1. a Values are means of eight replicates per treatment. Means within the same row not sharing a common uppercase superscript letter differ significantly (P ≤ 0.05). EO, essential oil contained 25 % thymol and 25 % carvacrol as active components; SEM, pooled standard error of the mean; ND, not detected
  2. b Linear and quadratic responses of intestinal thymol or carvacrol concentrations to dietary EO dosages
