Coccidiosis is a parasitic disease that has a substantial negative impact on the poultry industry. It is caused by Eimeria tenella species resulting in hemorrhagic inflammation and the risk of contracting other diseases is increased. Anticoccidial drugs and live vaccines are currently the primary methods for preventing and controlling coccidiosis. This study was designed to research the study of Eimeria tenella infection in broiler chickens, emphasizing pathological changes and treatment.
