| Amp | 100 | 87.36 | 13.68 | 84.01 | 173.35 |
| Amp + Sul | 100 | 93.44 | 15.85 | 85.36 | 177.29 |
| Tolt | 100 | 82.88 | 30.95 | 54.68 | 150.99 |
| NegCntr | 100 | 100 | 0 | – | 200 |
| PosCntr | 100 | 69.64 | 100 | – | 67.56 |
AST: Anticoccidial sensitivity test = (average lesion score in infected-unmedicated group – average lesion score in medicated group)/average lesion score in infected-unmedicated group × 100%. AST ≥ 50% was judged to be sensitive and < 50% was resistance; ACI: Anticoccidial index = (rate of relative body weight gain + survival rate) – (lesion score + oocyst value). An ACI value of ≥160 indicated sensitivity; a value < 160 indicated resistance, Oocyst value = (OPG output of each group/OPG output of PosCntr group) × 100; Tolt: toltrazuril; Amp: amprolium hydrochloride; Amp + Sul: Amprolium hydrochloride + sulfaquinoxaline sodium; NegCntr: uninfected-unmedicated negative control; PosCntr: infected-unmedicated positive control.
