Toltrazuril solution and preparation method thereof

The invention aims to disclose a toltrazuril solution and a preparation method thereof. Each 100mL of toltrazuril solution comprises the following components by weight: 2 to 5g of toltrazuril, 20 to 50mL of polyethylene glycol 400, 20 to 50g of propylene glycol, 0 to 40mL of anhydrous ethanol and a proper amount of ethanolamine. Compared with the prior art, the toltrazuril solution has the advantages that medicament resistance is avoided, the intracellular development stage of various coccidia and various medicament-resistant coccidium strains can be controlled by only using the toltrazuril solution for two days, and the safety is high, so that the toltrazuril solution can exert an optimal effect without affecting the growth and the utilization rate of a feed; and the toltrazuril solution can be mixed with multiple medicaments for use, remarkably reduces the death rate, realizes quick recovery and quick growth, saves resources, is easy to control and suitable for large-batch production, and fulfills the aims of the invention.
