  1. BW body weight, ADG average daily gain, ADFI average daily feed intake, F/G feed conversion
  2. NC negative control, SP positive control (chicks were challenged with S. pullorum from 8 to 10 days of age); EOL, EOM, EOH chicks supplemented with 30 mg/kg, 60 mg/kg, 100 mg/kg Artemisia argyit essential oil, respectively.
  3. a–cMeans within a row with different superscripts are significantly different (P < 0.05). P-value represent the difference comparison between group NC, SP, EOL, EOM and EOH groups.
