Treatment and Prevention of Ascariasis in Turkeys

Ascaridiosis in turkeys is a parasitic disease caused by Ascaridia galli, one of the most prevalent helminth infections in poultry. This disease is particularly widespread among turkeys raised in semi-intensive or free-range systems and leads to decreased productivity, stunted growth, weakened immunity, and economic losses. Clinical signs include loss of appetite, weakness, poor feather condition, diarrhea, and growth retardation. In severe cases, it can result in mortality. Diagnosis is mainly based on microscopic examination of feces, where characteristic Ascaridia galli eggs can be identified. Necropsy of deceased birds may reveal large, white worms in the intestines, confirming the diagnosis. Treatment involves the use of broad-spectrum anthelmintic drugs such as albendazole, fenbendazole, levamisole, and piperazine, which are administered through feed or drinking water in specific doses. Correct dosing and treatment duration are essential for effective control. Preventive measures include regular disinfection of cages and equipment, maintaining hygienic and dry conditions, ensuring clean feed and water, and conducting periodic veterinary monitoring. Prophylactic deworming every 3–4 months is recommended to reduce infection risk. This study highlights the biology, epidemiology, clinical presentation, diagnosis, treatment, and prevention of ascaridiosis in turkeys, emphasizing the importance of early detection and control to maintain flock health and productivity.
