"After hatch, a total of 168 chicks were weighed individually (mean weight 47.0 +/- 0.5g) and used in a completely randomized design with two treatments and six repetitions, with 14 animals per repetition. Animals in the control group (CG) were administered 0.2 mL of Marek's vaccine suspended in sterile saline solution subcutaneously, whereas the animals in the antimicrobial-administered group (AG) received 0.2 mL of Marek's vaccine suspended in sterile ceftiofur solution (0.2 mg ceftiofur sodium)."

Cloacal swabs were randomly collected from two animals per repetition before vaccination (day 0) and at 3, 5, 7, 9, 11 and 14 days post-hatching
