Using duck equipment can effectively reduce the outbreak of viral hepatitis

I believe that many farm owners have heard the word viral hepatitis. It is a viral disease that can be widely spread in ducks. Viral hepatitis is famous for its rapid onset, rapid spread and high mortality. Many farm owners have heard about viral hepatitis and lost their courage. It also makes many farms bankrupt. When it comes to the disease, it is manifested as a reverse attack. The pathogenic bacteria of the disease It is duck hepatitis virus. Viral hepatitis usually targets ducklings within 21 days of age. Ducklings between four and five weeks of age can also be infected. Even the adult ducks with weak constitution also have the risk of infection. However, the adult ducks will not be infected, but become virus carriers and infect other ducklings. In addition, the disease may appear in all seasons of the year, but it is usually more likely to appear in spring. There are many ways of transmission of the disease, including feed, water source, utensils, human contact and even the whole site. The feces of the first two months after recovery may also be the transmission medium.
The use of duck raising equipment can effectively reduce the incidence rate of the disease. Because of the overall design of the duck raising equipment and the feeding environment, the media can be cleaned up quickly. In the past, the incidence rate of the disease was one hundred percent, the mortality rate was ninety percent, the morbidity and mortality rate decreased gradually with the increase of age. Now, the incidence rate of the duck was reduced to below fifty percent after using the duck raising equipment.
