Table 8 Analytical concentrations of thymol and carvacrol in intestinal digesta

From: In vitro antibacterial activity of thymol and carvacrol and their effects on broiler chickens challenged with Clostridium perfringens

Item a Dietary EO concentration (mg/kg) SEM P-value Linear b Quadratic b
0 60 120 240
Thymol (μg/g digesta) ND 0.21B 0.46B 0.80A 0.076 <0.001 <0.001 0.586
Carvacrol (μg/g digesta) ND 0.20B 0.29B 0.71A 0.076 <0.001 <0.001 0.677
  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
