SR, RBWG, OPG index, cecal LSI, and ACI were calculated using the formulae described in the Materials and methods.
Mock represents the non-challenge control in which chickens received food and water without any treatment.
ET represents the ET challenge control in which chickens were inoculated with ET without any treatment.
A3 and A1 represent EM treatment 3 days before and 1 day after ET infection, respectively.
ACI, anticoccidial index; EM, extract and essential oil mixture (non-toxic concentrations of Punica granatum L., Plantago asiatica L., Bidens pilosa L., Acalypha australis L., Pteris multifida Poir, and Portulaca oleracea L. Sp. Pl. extracts and Artemisia argyi Levl. et Vant. and Camellia sinensis [L.] O. Ktze essential oils); ET, Eimeria tenella; LSI, lesion score index; OPG, oocysts per g of excreta; RBWG, relative body weight gain; SR, survival rate.
