Coxiril®, containing 0.5 % diclazuril, is intended for use in the control of coccidiosis in guinea fowl at concentrations between 0.8 and 1.2 mg diclazuril/kg complete feed. Since diclazuril from Coxiril® is considered safe for turkeys for fattening with a margin of safety of 12-fold the intended dose, this conclusion can be extrapolated to guinea fowl, which is a physiologically similar minor species.
