Newcastle disease

Newcastle disease in quail mostly occurs in the late stage of chicken Newcastle disease epidemic. The virus invades the body and causes sepsis. The mortality rate is high. The disease can occur all year round, but it occurs frequently in spring and autumn. The saliva and feces of sick birds contain a large number of viruses, which infect healthy birds through feed, drinking water and utensils. Sick birds can also spread the virus through the air when they cough or sneeze. At the beginning of the disease, neurological symptoms generally appear, with the head backward or sideways, fluid flowing from the mouth, loss of appetite, pulling green and white pupa, soft shell eggs and white shell eggs, and usually die within 2-3 days. Acute cases develop difficulty breathing, neurological disorders, and soon die. For young quails aged 40-70 days, the incidence is higher, and the incidence is lower than 7 months. Mortality was 50% at the time of onset before laying, and decreased to 10% at the time of onset after laying, but the course was longer and egg production was significantly reduced. Post-mortem symptoms are mainly hemorrhagic lesions of the glandular stomach, intestine, and ovary, especially needle-like bleeding points or bleeding spots on the mucosa at the junction of the esophagus and glandular stomach. There is no specific cure for this disease, and prevention should be the primary focus. A Newcastle disease vaccine is the most effective way to prevent this disease. Newcastle disease Ⅱ vaccine can be used, drinking water immunization, 3 consecutive times. For the first time at 4 days of age, diluted with 1 ml of a series II attenuated vaccine plus 1000 ml of cold water for drinking, and 15,000 ml of water for every 1,000 chicks. The second time at the age of 20, drink about 2000 ml. The third time at 50 days of age, drink about 5000 ml. The night before the immunization of drinking water, the water supply was stopped, causing quail to have thirst, and the water with vaccine was put in the next morning so that all quails could drink water and finished drinking within 2 hours.
