Coxiril®, containing 0.5 % diclazuril, is intended for the control of coccidiosis in turkeys for fattening at concentrations between 0.8 and 1.2 mg diclazuril/kg complete feed. The highest proposed use level (1.2 mg diclazuril/kg feed) is considered safe for turkeys for fattening. Diclazuril has no substantial antibacterial activity.
