SEM, standard error of the mean; IBW, initial body weight; FBW, final body weight; ADG, average daily gain; ADFI, average daily feed intake; G:F, gain to feed ratio; DO, diarrhea occurrence.
NC, negative control: basal diet; PC, positive control: NC+125 mg performance-enhancing antibiotic (enramycin 8%)/kg diet; EO100, NC+100 mg essential oil blend/kg diet; EO200, NC+200 mg essential oil blend/kg diet; EO400, NC+400 mg essential oil blend/kg diet.
DO (%) = dividing the sum of DO by the total number of observations in each treatment and then multiplying by 100%.
Averages with different uppercase superscripts in the same row differ significantly by the Student-Newman-Keuls test (p<0.05).
Averages with different lowercase superscripts in the same row differ significantly by the Tukey-Kramer test (p<0.05).
