Used primarily in veterinary medicine, especially in poultry and livestock, to control and treat coccidiosis—a parasitic disease affecting the intestinal tract. It is effective against various species of Eimeria that cause significant production losses in chickens and other birds. Often administered through drinking water or feed, it helps reduce mortality and improve weight gain in infected animals. Also used as a growth promoter in some regions, though its use is regulated due to concerns about residue and antimicrobial resistance. Its application is typically limited to specific phases of animal rearing, especially in young birds during high-risk periods.
