1 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). At each time point, orthogonal polynomial contrasts analysis was conducted to see linear pattern (L) and quadratic pattern (Q) among the treatments.
