Abstract: An anticoccidial composition which comprises a compound of the formula ##SPC1##Intimately dispersed in an inert edible carrier, wherein R.sub.1 and R.sub.2 are each hydrogen, an aliphatic acyl group, an aromatic acyl group or a heterocyclic acyl group, and at least R.sub.1 and R.sub.2 is said heterocyclic acyl group; or a salt thereof.The composition is a preventive and curative anticoccidial agent for poultry and domestic animals. Particularly, it shows a significant activity against chronic coccidiosis caused by Eimeria acervulina.The composition is less toxic for animals, besides it has an advantage that it is also effective for coccidiosis caused by coccidia resistant to the known anticoccidial agents.
