  2. 1Values represent the mean of twelve pens with four pigs per pen. The dietary treatments were: PC (positive control); NC (negative control, 150 kJ/kg DE lower than the PC diet); EO (NC diet supplemented with 0.025% EO product which contained at least 4.5% cinnamaldehyde and 13.5% thymol).
  3. a,bMeans in the same row with different superscripts are significantly different (P < 0.05).
