Used primarily as a coccidiostat in poultry farming, it prevents and controls coccidiosis, a parasitic disease affecting the intestinal tract of birds. It works by interfering with the thiamine uptake of coccidia parasites, effectively inhibiting their growth and reproduction. Commonly added to feed or drinking water, it is widely applied in broiler and layer operations to maintain flock health and improve growth performance. Also used in calves and other livestock to manage intestinal parasites. Its non-antibiotic nature makes it suitable for use in programs aiming to reduce antibiotic reliance in animal production.
