1. Symptoms of duck viral hepatitis
Ducks with viral hepatitis suffer from mental atrophy, shrunken heads and hunched backs, anorexia, diarrhea, loose feathers, slow movements, closed eyes and lethargy, and twitching legs. Before death, it is in an angled arch retraction posture, and within a few hours after the onset of neurological symptoms, it dies of exhaustion due to dyspnea.

Cherry Valley Duck House is sprayed with 100 poison or other antiviral disinfectant once a day, and the site is sprayed with 2% to 3% caustic soda once a day.
2. Emergency immunization
Emergency vaccination of anti-duck viral hepatitis high immune serum or duck viral hepatitis high immune yolk, 0.5 to 1.0 ml each, combined with ribavirin mixed intramuscular injection, can effectively control the epidemic and reduce mortality. At the same time, mix with astragalus polysaccharide, vitamin C, ciprofloxacin lactate for 3 days.
3. Prevent the spread of pathogens
Strengthen feeding management, prohibit non-breeders from entering duck houses, prevent the spread and spread of pathogens, and reduce stress factors. Five days after taking the above measures, the outbreak was brought under control.
3. Prevention of duck viral hepatitis
Strengthen feeding management, establish a strict sanitation and disinfection system, and improve the awareness of epidemic prevention Before entering the hatching, the immunity of the breeding duck farm to the disease should be understood, and if the female duck is indeed immune, the female antibody of the chick can be maintained for about 2 weeks. If the environmental health status of the rearing is poor, active immunization of duck viral hepatitis vaccine is recommended at 10 to 14 days of age. If the cherry valley duck hen is not immunized, the chicks should be immunized at 1 day of age. Once the disease occurs in chicks, yolk antibodies should be injected quickly, which can quickly and effectively reduce mortality and prevent the spread of pathogens. Passive immune prophylaxis can also be performed with yolk antibodies, and the duration of a single immunization is 5 to 7 days.
