Effects of BLJ on composition of cecal microbiota at the phylum levels. a) Composition of caecal microbiota of the broiler chickens at phylum level. b) Comparison of the relative abundances of the two main bacterial phyla. A = a basal diet + unchallenged; B = a basal diet with 500 mg/kg of BLJ + unchallenged; D = a basal diet + challenged; and G = a basal diet with 500 mg/kg of BLJ + challenged
