First, the incidence Miquan wool workers raised 2,000 chickens. When they were 18 days old, some chickens were found to be lack of energy, decreased feed intake, and increased water intake. They used bursa vaccine twice as much water, combined with antiviral drugs and antibiotics. After the treatment, the ideal result was not received. There was a death on the 20th day, and the death rate was on an upward trend. The number of deaths on the 21st day reached 20. Second, the clinical symptoms The diseased chickens were yellow and white, and the severe chickens were white rice soup-like feces, with their heads closed, eyes closed, cold, and the feathers were dull and dull and dull. Some chickens have perianal feathers that are contaminated with faeces and have scrofula. Third, the necropsy changes Chest muscles and leg muscles have strips of hemorrhage, swelling of the bursal of Fabricius, obscure mucous membranes after cutting of the bursa of Fabricius, surface bleeds or chronic hemorrhages, kidneys with varying degrees of swelling, pale, with urate Deposition, glandular stomach junction, dark brown hemorrhagic necrosis zone, intestinal mucosal bleeding. Fourth, diagnosis Based on the above, combined with the prevalence of local diseases, it is diagnosed as Infectious Bursal Disease. V. Treatment 1. Treatment plan Three intramuscular muscle cells were injected intramuscularly with yolk antibody (1 ml/body) and amikacin (2 ml/10 chickens). The poison g is concentrated twice during the day; it can be consumed alone in the evening for 3 days. 2. Drug analysis Poly I: Inducing the body to produce interferon, blocking viral replication, and can enhance the efficacy of yolk antibody. Yolk antibody-neutralizing bursa virus. Poison gram - antiviral and antibacterial double-effect combination, combined with polymyosin to prevent virus replication, can also prevent secondary bacterial infection. Clinton relieves kidney damage caused by Bursal Disease. 3. Treatment advice In addition to strengthening the daily disinfection work, we must also pay attention to the vaccination work, and recommend the use of multi-valent seedlings for prevention, which can often achieve better preventive effects. Severe symptoms of diarrhea in affected chickens can be controlled by the use of antispasmodic drugs (eg, engravers). At the same time, we must pay attention to improving the environment and strengthening ventilation, especially at night.

Since bursal disease causes kidney damage, the use of sulfonamides, quinine, aminoglycoside and other kidney-damaging drugs is minimized during the disease.
