  1. CTL: control diet without any antibiotic or prebiotic; VIRG: control diet supplemented with 16.5 g/ton virginiamycin; LXOS: control diet supplemented with 1 g/kg xylo-oligosaccharides; HXOS: control diet supplemented with 2 g/kg xylo-oligosaccharides; SEM: standard error of the mean. Each mean represents six replicate cages with five broilers per cage. a,bMeans in the same row with different superscripts differ (P < 0.05).
