Special attention should be paid to the prevention of rat damage. Doors and windows should be installed to prevent rats. Carefully formulated diet: According to the different ages of geese, carefully formulated feed, appropriate feeding of green material. We must do a good job in epidemic prevention work: Disinfect the pigs before and after they are sold, use 2% formalin, or disinfect with lime powder. The geese who used the epidemic prevention needles were selected to enter the field, or the geese serum was injected immediately after entering the geese. Influenza can be controlled by injection of kanamycin and streptomycin.
