At present, farms are heavily polluted, and viral hepatitis, escherichia coli, and some viral diseases of ducks occur from time to time. Sometimes, mixed infections occur and losses are large. In order to improve the efficiency of breeding ducks, the use of drugs is summarized as follows:
1. After infection of a duck with a pathogen, there are occasional secondary viral infections due to reduced resistance. Therefore, antiviral drugs may be added at the same time as the use of antibacterial drugs.
2. Do not change drugs frequently. If a drug does not work for 2 to 3 days, consider choosing a new treatment plan. When using antibiotics, it should be doubled for the first time. Generally, 2 to 3 different broad-spectrum antibacterial drugs can be used during treatment. Only one drug can be used for prophylaxis.
3. When dispensing water or ingredients, you should have a good grasp of the amount of water or feed used in the mix, so that it can be served within 1 hour. If the medicine is mixed, it should be uniform.
4. As soon as the incoming ducklings are bumpy along the way, and the ducklings have a greater stress on the environment, the brooding house is not completely sterilized. It is very easy for the ducklings to develop. At this time, the prevention of the administration of the ducklings can inhibit the occurrence of the disease. It can improve the immunity of ducks and it is important for rearing. When ducklings are stressed, such as transport, transfer, refueling, climate change, etc., antibiotics and electrolysis should be used for prevention.
5. The ducklings were given hyperimmune serum within 24 hours of introduction, 1.0 to 1.5 ml each, and 4 to 5 days were injected with inactivated oil adjuvant adjuvanted with duck infectious serositis, 1.0 ml each.
6. It is easy to induce respiratory diseases by spraying the disinfectant in the duck house. Therefore, preparations with less irritation to the respiratory tract should be used, such as complexed iodine preparations, etc., or pre-dose for meat ducks.
