What should farmers do during immunization? Now, vaccination is still the best way to prevent pig disease, but it is important to note that during vaccination, that is, when pigs are least stimulated, there is still a lot of work to be done if you don't want to fail. . First, pay attention to the reaction of pigs after vaccination Although the technology of vaccination is very mature today, there are still cases where the pig may become unwell. Therefore, after immunization, pay close attention to the pig's reaction. If the pig has an adverse reaction, it is best to ask the local veterinarian or animal epidemic prevention staff for immunological side effects. Otherwise, it is very likely to cause unnecessary casualties. Second, eliminate potential stress factors Pigs are actually in a sub-health state before the immune system is formed after vaccination. At this time, pigs are more likely to be stressed or even sick than usual. Therefore, it is best to check carefully to eliminate all potential factors that may cause a stress response in pigs. For example, is the ventilation condition of the pig house excellent, whether the air quality is up to standard; whether the temperature of the pig house is suitable, whether it is too cold or overheated; whether the humidity of the pig house is scientific, whether it is too moist or excessively dry; whether the breeding density of the pig house is reasonable, The pig has not enough space for activities and so on. In addition, after the vaccination, the pigs should not rush to change the feed or circle or group. Only when the immunity is actually formed, the pigs are completely prevented from being stressed, so as to ensure the quality of the immunization. Third, eliminate all disease-fighting microorganisms As we have already said in the second point, pigs are sub-healthy after a short period of immunization, so pigs are also the most susceptible to illness during this time. If the sanitary conditions of the pig house are not good and the pathogenic microorganisms are flooded, the probability of disease in the pig will increase greatly. In general, the disinfection program on the farm should be strictly carried out within 21 days after the immunization of the pig. Don't let the idlers wait to enter the farm. All the used utensils on the farm are also strictly disinfected, including the breeder entering and leaving the farm. In this way, the pathogenic microorganisms can be completely eliminated. 4. If necessary, make a waiver Even if all the surrounding work is done better, sometimes because of the differences in individual pigs, or the relationship between vaccine quality and dosage, it is impossible to guarantee 100% immunization success. Therefore, in addition to observing the response of the pig just after the vaccination, it is necessary to follow up the observation later. Generally, within three weeks after the vaccination, the immune effect of the pig should be tested in a comprehensive manner so that it can be found which immune antibodies are not formed. Pigs that do not form effective antibodies should be replenished. If it is a vaccine problem, it is best to replace the vaccine to ensure a healthy immune effect. The above is the specific work that the farmer needs to do during the immunization of the pig, for your reference only.
