Duck arthritis syndrome
1. Main symptoms.
Most of the diseased ducks were articular swelling, mostly in the tarsal joint, followed by the knee joint, hip joint and toe joint. The joint was swollen, purplish red, hot on palpation, soft at the beginning of the disease, and then gradually hardened, showing severe claudication or inability to walk, reduced food intake, gradual weight loss, and increased mortality.
2. Preventive measures.
The disease is related to a variety of bacterial infections, such as staphylococci, salmonella, Riemerella anatipestifer and so on. In the feeding system, we should adhere to the "all in and all out", strictly disinfect, and take corresponding prevention and control measures against Riemerella anatipestifer infection. Duck breeders also need to do a good job in disinfecting breeding eggs and hatching equipment to prevent the vertical spread of salmonella. At ordinary times, we should pay attention to prevent feed pollution, especially fish meal and meat meal, and pay attention to bacteriological examination. Remove sharp foreign bodies in duck house mattress and sports ground to prevent staphylococcal infection.
