1. Ensure effective disinfection. At present, aldehydes, alkalis, halogens, peroxides, and quaternary ammonium salts can be used to disinfect the farm environment. Clean and rinse before disinfection, and then spray the liquid disinfection. In addition to determining the appropriate drug concentration when choosing a disinfecting drug, the cost of the drug should also be considered.
2. Follow the order of disinfection. When the duck farm is sterilized, it shall follow the dirt road after the first clean road (the road that transports feed, etc.) (the road where the dredger truck runs); the duck farm area shall be prepared, and the duck rearing area shall be prepared; the duck area shall be firstly planted, and the commercial duck area shall be used first. Disinfection tanks in duck houses are strictly prohibited from borrowing or mixing.
3. Note the frequency of disinfection. Under normal circumstances, not less than twice a week in the audience and with duck disinfection; during the onset, insist on sterilizing ducks every day.
Second, a sound immunization program for basic immunization can prevent diseases from happening. Duck immunization should avoid peak egg production, duckling immunity should consider the presence of maternal antibodies. The duck farm can introduce vaccines for immunization in a timely and appropriate manner according to the conditions in the region and the disease.
Vaccine immunity is a stress on the duck population. In order to reduce this stress, electrodialysis can be added to feed or drinking water. When using oil emulsions to inactivate vaccines, first return the vaccine to room temperature. In hot summer weather, when vaccinating, it is necessary to ensure sufficient drinking water first, and try to arrange immunization time in the morning when it is cool. In immunization, shake the vaccine. When vaccinating tissue attenuated vaccines, the entire immune time is best controlled within one and a half hours.
Third, establish a scientific disease prevention system
1. Turn off the entrance. It is forbidden for outside vehicles and personnel to enter the field; they must be hand-sterilized and enter the production area before they can enter through the disinfecting channel (with disinfecting water tank and ultraviolet light).
2. Prevent cross-infection. Breeders are prohibited from stringing and stringing to prevent cross-infection. The environment in the area should be kept clean and free of pollution. Do not lightly spread the infectious diseases to birds, and prevent their feces from contaminating the feed and sports grounds; adhere to the regular disinfection of the whole area and ducks, and sterilize them every day during the onset; do a good job of eradicating rodents and mosquitoes Flies work. Dead ducks and anatomy must be detoxified.
3. Do a good job of disease prevention. According to drug susceptibility testing, clinical drug use, age and season of onset, combined with production practices, access to the field of preventive drug program. When choosing drugs, avoid using fake and inferior veterinary drugs to delay the illness.
4. Do a good job of monitoring the disease. Routine monitoring of the disease in duck farms in addition to highly pathogenic avian influenza, duck plague, duck viral hepatitis, but also based on local conditions, select other necessary diseases for monitoring.
