Select drugs, scientific drugs, and do a good job in environmental disinfection.
Ensure effective disinfection
Currently available for the farm environment disinfection of drugs: aldehydes (formaldehyde, glutaraldehyde), alkalis (fire alkali, quicklime), halogens (chlorinated preparations have bleaching powder, disinfection Wang, Wei Wei, etc., iodine preparations have iodine Oxygen) peroxides (peroxyacetic acid) and quaternary ammonium salts (poisonous). Before cleaning, rinse and rinse to prevent the presence of organic substances such as feces, urine, sepsis, body fluids, etc., and then spray the liquid to disinfect.
In addition to determining the appropriate drug concentration when choosing a disinfecting drug, the cost of the drug should also be taken into consideration. After a comparative calculation, several disinfecting drugs suitable for this field are finally obtained in order to rotate the drug. In this way, it not only plays a role in disinfection, but also reduces the cost of disinfection, and can extend the use time of disinfectants in the field.
Follow the order of disinfection
When the duck farm is sterilized, it should follow the first clean road (the road that transports feed, etc.), and the rear dirt road (the road where the dredger truck runs); the duck farm area and the rear duck farm area are prepared; the first duck area, and the later commercial duck area. . Disinfection tanks in duck houses are strictly prohibited from borrowing or mixing.
Pay attention to the disinfection frequency
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.
Follow the procedures, use the vaccine, and do a good job of basic immunization.
In order to prevent the occurrence of infectious diseases, the farm must establish a reasonable immunization program to protect the health of the duck population. There may be more than one type of infectious disease in a group of ducks. The nature of vaccines (bacteriophage) that can be used to prevent these infections is not the same. The antibodies produced in ducks are sufficient to withstand the attack of pathogenic microorganisms (immunity). Period) is also different. Therefore, when a certain duck population uses multiple vaccines (bacterins) to prevent different diseases, it is necessary to formulate the number and time of vaccination according to the immune characteristics of various vaccines (bacterins), which is used in practice. Immunization program. A reasonable immunization program can well prevent the occurrence of the disease and minimize the stress response caused by the immunization of the vaccine to the ducks. The immunization of ducks should avoid the peak of egg production and the duckling immunity should consider the presence of maternal antibodies. . Vaccination of ducks should reduce the waste of human and material resources and improve the quality of immunity. The key is to look at the immune effects. The duck farm can introduce timely and appropriate vaccines for immunization according to the conditions of the region and the disease. For example, duck hepatitis virus must be immunized in areas with high viral hepatitis or threatened areas.
Vaccine immunity is a stress on the duck population. In order to reduce this stress, electrodialysis can be added to feed or drinking water. In different seasons, immunization should pay attention to some different details. When using an oil emulsion to inactivate a vaccine, first return the vaccine to room temperature. Otherwise, the vaccine injected into the subcutaneous tissue will form a vaccine group and it will not be easily absorbed. In summer, when the climate is hot, when the vaccine is vaccinated, it is necessary to ensure sufficient drinking water and try to immunize. The time is cool in the early morning. In the immunization, the vaccine should be shaken continuously so that each duck can obtain equal and effective antigen immunity. When the attenuated virus vaccine is inoculated, the entire immune time should be controlled within one and a half hours to prevent the vaccine from affecting the virus's immune activity if it is exposed for a long time in an overly temperatureed duck house.
Focus on the big issues, take care of the details, and establish a scientific disease prevention system.
Put a good entrance at the entrance to the gate and strictly sign “Population prevention, refused to visitâ€. Specially guarded and no outside vehicles and personnel are allowed to enter the market. When entering the production area, they must be hand-sterilized and sterilized and the disinfecting channel (with disinfecting water tank and UV light) can enter. .
To prevent cross-infection, each breeder must prohibit cross-cutting 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. Diseased ducks and anatomical diseases must be treated in a non-hazardous manner. They must not be allowed to pollute the environment and cause human-made diseases.
Do a good job of disease prevention and treatment Veterinarians should be diligent in dissecting the dead duck. The disease should be tested in time in the laboratory, and drug treatment should be selected based on the drug sensitivity test results. After the initial administration, the veterinarian should still follow the treatment until he is cured. The veterinarian obtains this site's preventive drug program based on drug sensitivity test, clinical drug use, age of onset and season, combined with production practice. When choosing drugs, avoid using counterfeit and inferior veterinary drugs to delay the illness and lead to serious economic losses.
Do a good job of monitoring the disease
According to the actual situation in the local area, an epidemic disease monitoring plan shall be formulated. The epidemic disease routinely monitored at a meat duck farm shall be monitored in addition to highly pathogenic avian influenza, duck gizzard, and duck viral hepatitis, and other essential diseases should be selected in accordance with the local actual conditions. .
