Prevention and control methods of porcine circovirus

At present, there is no effective treatment for the disease, and all sick pigs end in death. Once sick pigs are found, they should be eliminated immediately. Sometimes, due to the large number of sick pigs, it is difficult to start, and it is necessary to isolate the sick pigs to a pig house far away. At present, the vaccine is still in the research stage, and good management is very important. Specific measures are as follows:

first

Cultivate suckling piglets, wean them in time, prevent the occurrence of yellow and white dysentery, give suckling pigs high-quality complete feed and enhance their immune function. Only strong piglets can resist this disease.

second

Attach importance to and strengthen the vaccination of common concurrent infections. Because of blue ear disease, parvovirus disease, pseudorabies, streptococcosis and so on. Often complicated or secondary to this disease, sows and newborn piglets should be vaccinated accordingly to reduce or avoid concurrent infection as much as possible, which can reduce the harm of this disease and is conducive to the rehabilitation of this disease.

third

Comprehensive control measures include the following points: ① strict access system should be implemented in piglet houses; 2 Don't mix pigs from different sources, and don't combine pigs of different months in the same pigsty; ③ appropriately reduce the feeding density of piglets; ④ Pay attention to biological safety measures in pig farms, and reduce or avoid environmental stress factors (temperature, humidity, air leakage, harmful gases, etc.). ); ⑤ Do a good job of epidemic prevention and hygiene in pig farms, such as immunization, deworming and drug control. To ensure that pigs are in a healthy and stable immune state; ⑥ Reasonable temporary disinfection and air disinfection. After the sick pigs are eliminated, the pigsty should be thoroughly disinfected with pigs, and the pigsty should be disinfected with air.
