Effects of ABX treatment on the growth performance, mortality rate and immune organ index of broiler chickens with cages and ground litter floor pens. The body weight (A), body weight gain (B), feed intake (C) and feed conversion ratio (D) were analyzed by weighted. The spleen index (E), thymus index (F) and bursa of fabricius index (G) were analyzed by weighted. All graphs are presented as mean, with the standard deviation (SD) shown via the whiskers. The main effect and interaction effects were analyzed using the general linear model (GLM) procedure, with the P values for the main effects written out below each plot. The one-way ANOVA and multiple comparisons were performed when interactive effects differed significantly. Cage: cage control group; Cage + ABX: cage with ABX group; Litter: ground litter control group; Litter + ABX: ground litter with ABX group
