Figure 2.

Cecal lesion score of broiler chickens infected with different dosages of Eimeria tenella on 6 days post-infection. Cecal lesion score was measured in the T0 (treatment 0; Sham-challenged with phosphate-buffered saline); T1 (treatment 1; challenged with 6250 sporulated oocysts of E. tenella); T2 (treatment 2; challenged with 12,500 sporulated oocysts of E. tenella); T3 (treatment 3; challenged with 25,000 sporulated oocysts of E. tenella); T4 (treatment 4; challenged with 50,000 sporulated oocysts of E. tenella) groups on 6 days post-infection. Different letters at the same time point represent significantly different (p < 0.05) by utilizing the Kruskal–Wallis test followed by the Dwass, Steel, Critchlow-Fligner post hoc test.
