Sulfanitran is primarily used in the veterinary field as an antiprotozoal and antibacterial agent. It is commonly added to animal feed to prevent and control coccidiosis, a parasitic disease affecting the intestinal tracts of poultry and livestock. By inhibiting the growth of harmful protozoa, it helps improve the health and growth rates of animals, ensuring better productivity in farming operations. Additionally, it is sometimes used in combination with other drugs to enhance its effectiveness against a broader range of pathogens. Its application is particularly significant in the poultry industry, where maintaining animal health is crucial for food safety and supply.
