How to treat viral duck hepatitis? Meat duck viral hepatitis is actually an acute infectious disease of ducklings. It spreads fast and has a short course. The mortality rate of new epidemic areas is as high as 90%. In almost all batches of duck-raising areas, the mortality rate is about 30%, which often causes huge losses to the duck industry. Today, let's learn about the diagnosis and prevention of viral hepatitis in meat ducks. First, clinical symptoms At the beginning of the disease, the body temperature of the meat duck was normal. As the age increased, the condition developed. The diseased duck appeared unstable and lack of energy. When walking, the feet were opened outwards, and the cicadas, sputum, diarrhea and claws were severely dried. Some fell to the ground because of diarrhea. The sick duck landed on the back, struggling but still unable to stand, and some appeared high, turned to the head, unstable standing, twisted neck, etc., then the meat duck tongue extended, the feathers around the eye circle were wet, tears, feces thin, coughing, snoring Phenomenon, staying in the corner of the duck house, individual squatting or lying on the side, the feed intake is greatly reduced, the sick duck is thin. Second, the diagnosis points The main lesions of the disease are in the liver and gallbladder. The liver is swollen, the texture is soft, and it is easy to tear. The autopsy shows that the hepatomegaly is pink or khaki, and the surface has deep purple bleeding spots or plaques ranging from needle tip to rice. A preliminary diagnosis can be made based on the above points, and a laboratory test is required to confirm the diagnosis. Third, prevention and treatment Choose regular duck seedling suppliers to purchase seedlings, strengthen feeding management, provide high-quality full-price feed, supply clean drinking water, and do a good job in duck house hygiene and disinfection. Add detoxification to the feed to prevent mildew in the feed. The early onset of viral hepatitis in ducklings is rapid, so it is necessary to highlight the word "early" for the prevention and treatment of this disease. Early prevention without disease, early measures to prevent the loss to a minimum. The female duck can be vaccinated twice with the duck virus attenuated vaccine, the first time 15 days before laying, each subcutaneous or intramuscular injection of 1 ml, and then injected 2 ml every 7 days or so. Two to three weeks after the second vaccination, the eggs produced by the breeding ducks can be used for seeding, and the hatched ducklings have strong natural passive immunity. After the onset of the duck population, the body's resistance will be reduced, so it is particularly prone to cause enteritis or secondary disease such as enteritis, colibacillosis and infectious serositis. Therefore, while using antiviral drugs, it is also necessary to use antibacterial drugs. At the same time, strengthen feed nutrition and improve the breeding environment. After the onset of the duck population, it is necessary to increase the content of vitamins and minerals in the feed, enhance ventilation, and discharge the dirty gas in the house. When the density of ducks is high, they should be properly grouped. To prevent excessive moisture in the duck house, replace the litter in time. In order to avoid the aggravation of the disease due to stress factors, the environment inside and outside the duck shed should be kept relatively quiet. Because there is no specific treatment for this disease, it can be supplemented with calcium. In addition to symptomatic treatment of ferrets, fever, anti-virus, and supplemental electrolysis, supplementing physical strength, the most important thing is to supplement calcium.
