Result for Percentage Optimum Anticoccidial Activity (POAA).
| Treatment | Initial Body Weight (g) | Final Body Weight (g) | GSR | POAA % |
|---|---|---|---|---|
| Amp | 213.74 ± 2.44 | 374.20 ± 0.66 | 1.75 | 86.58 |
| Amp + Sul | 227.25 ± 1.59 | 398.86 ± 4.10 | 1.76 | 88.96 |
| Tolt | 217.55 ± 14.52 | 369.77 ± 21.97 | 1.70 | 59.49 |
| NegCntr | 236.69 ± 4.53 | 420.35 ± 3.40 | 1.78 | 100.00 |
| PosCntr | 217.64 ± 7.15 | 345.54 ± 7.85 | 1.59 | 0.00 |
POAA: Percent Optimum Anticoccidial Activity = (GSR in medicated group – GSR in infected-unmedicated group)/(GSR in uninfected-unmedicated group – GSR in infected-unmedicated group) × 100%, GSR (growth and survival ratio) = final body weight divided by initial body weight. POAA > 50% was judged to be sensitive and ≤50% was resistance; Tolt, toltrazuril; Amp, amprolium hydrochloride; Amp + Sul: Amprolium hydrochloride + sulfaquinoxaline sodium; NegCntr: uninfected-unmedicated negative control; PosCntr: infected-unmedicated positive control.
