cCON, chick control group; Cipro, ciprofloxacin lactate treatment group; cCCAB, chicks from the CCAB group. Significant differences in comparison with the cCON group are expressed as *P < 0.05 and **P < 0.01 by ANOVA and post-hoc least square difference test. n = 6 chicks per group at each time point.
