Especially in the newly cultured areas and batch rearing, it is not difficult to see the devoured farmers (farms). Gosling plague virus is spread mainly through the secretions of sick goose, excrement, eggs, and water, feed, utensils, and venues used by gooses. The prevention and control results are summarized below. Goslings have a disease age of 2 to 30 days, the incidence of which is 5 to 20 days old, and the mortality rate is 75 to 100%; rarely more than one month. The most acute type of disease is most commonly seen in goslings aged 3 to 10 days after hatching. There are no early symptoms and the disease suddenly fell to the ground. Acute onset is more common in 5-15 days old goslings, the course of disease is 1 to 2 days, and the main manifestations are pull-white diarrhea, atrophy, hoarseness, no feeding or feeding, but no swallowing, and the food is thrown off. Walking slowly after hours, doze off, only drinking water, do not eat, serous secretions often flow out of the nostrils, eye socket depression, neck elbow, can not stand up, after the shock death.

In addition, the hatchery and utensils should be sterilized with 2% caustic soda or 0.2% sodium hypochlorite or 20% caustic liquor or 30% hot straw grey water.

With the fresh blood of the gosling and the rehabilitation goose, add 2.5 to 5% sodium citrate solution. Each goose neck is injected subcutaneously with 1.5 to 2.5 ml. After 24 hours, it is injected once again, which has good preventive and therapeutic effects. If the affected goose is infected with other bacterial diseases, each gosling should be intramuscularly mixed with 1000-2000 units of gentamycin, one for morning and evening, and two days for two to three days for gentamicin.

Each 10 goslings use Tongcheng Tiger 5 to 10 grams per day, nutmeg 20 to 25 grams, and chilly days add Guizhi 5 to 10 grams of Jianshui to soak in rice or the liquid and rice flour are slurried to feed sick geese. 2 to 3 days, the effect is significant, up to 70%.
When goslings are treated, combined with adjuvant therapy, 100 mg of VB1 tablets, 7 to 10 tablets of cod liver oil pills, 100 mg of Gantai Lok, and appropriate amounts of glucose and minerals should be added to improve the curative effect per kilogram of feed.
