  1. a,b Means in the same row with different superscripts are significantly different. (P < 0.05)
  2. 1control = basal diet + PBS; CP = basal diet + CP administration; L-LJ = basal diet with 1.0 × 105 cfu BS15/g diet + CP administration; H-LJ = basal diet with 1.0 × 106 cfu BS15/g diet + CP administration. Pen (n = 6 per treatment group) was used as the experimental unit for initial weight, final weight, DWG, FI, FCR and survival rate. An individual bird (n = 12 per treatment group) was used as the experimental unit for abdominal fat, breast and thigh percentages
  3. 2 DWG daily weight gain, FI feed intake, FCR feed conversion ratio (FI/body weight gain)
  4. 3% = percentage of 42-day body weight
