  1. aValues are means of eight replicates per treatment. SEM pooled standard error, EO essential oils
  2. bWhen the interaction between C. perfringens challenge and EO supplementation was not significant, linear and quadratic polynomial contrasts were performed on the main-effect means to EO dosages
