Formulations containing triazinones, selected from toltrazuril, ponazuril and diclazuril, a polynuclear iron(III) polysaccharide complex compound which are suitable for the simultaneous control of coccidiosis and anaemic states in animals and which exhibit a low amount of free iron ions even after storage, while the formulations comprises Ca2+and Na+in a molar ratio of Ca2+:Na+from ≥ 0 to ≤ 3. In one embodiment the triazinone is toltrazuril and the polynuclear iron(III) polysaccharide complex compound is iron(III) dextran glucoheptonate.本發明係關於一種包含三酮及多核鐵(III)多醣錯合物之調配物，該等三酮係選自托曲珠利(toltrazuril)、泊那珠利(ponazuril)及地克珠利(diclazuril)，該等調配物適用於同時控制動物中之球蟲病及貧血狀態且其甚至在儲存之後仍呈現少量游離鐵離子，同時該等調配物以≥0至≤3之Ca2+:Na+莫耳比包含Ca2+及Na+。在一個實施例中，三酮為托曲珠利且多核鐵(III)多醣錯合物為聚葡萄糖葡庚糖酸鐵(III)。
