Used primarily in veterinary medicine to treat protozoal infections, especially trichomoniasis and histomoniasis in poultry and other birds. It is effective against anaerobic bacteria and certain parasites, making it valuable in managing infections in livestock. Commonly administered through feed or water, it helps reduce mortality and improve growth performance in affected flocks. Due to potential toxicity and carcinogenic concerns, its use is restricted in food-producing animals in some countries, and withdrawal periods are enforced to prevent residues in meat and eggs.
