No: unchallenged broilers received aliquot of dilution at d 10. Yes: challenged broilers received sporulated 10⁴ oocysts of E. tenella, E. acervulina, and E. maxima at d 10. Control: a corn and soybean meal basal diet, anticoccidial: control diet + 60 g nicarbazin and 60 g narasin per ton of feed, oregano: control diet + 500 ppm oregano oil, and clove: control diet + 500 ppm clove oil.
