Core role
Stimulate specific immunity: Vaccines stimulate pigs to produce antibodies against specific pathogens (such as viruses and bacteria), allowing pigs to quickly clear or neutralize pathogens when exposed to wild viruses, avoiding disease
Forming a herd immune barrier: When most pigs are immunized, it can block the chain of disease transmission and protect individuals who are not immunized or have failed to immunize
Reduce economic losses: effectively prevent and control highly pathogenic and high mortality diseases (such as swine fever, foot-and-mouth disease, blue ear disease), reduce treatment costs, death losses, and decreased production performance
Ensuring public health safety: Some pig diseases are zoonotic (such as pseudorabies and certain types of foot-and-mouth disease), and immunization of pig herds can indirectly reduce the risk of human infection
Common vaccines and their protective targets
Swine Fever Vaccine: Preventing Classical Swine Fever (CSFV), protecting piglets until they are sold, and requiring 3-4 general immunizations per year
Foot and mouth disease vaccine: Due to the fast spread and high harm of foot-and-mouth disease, it is usually immunized once every quarter and five times a year
Pig Blue Ear Disease Vaccine: Immunization for breeding pigs before mating, first immunization for piglets at 3 weeks of age, reducing reproductive disorders and respiratory symptoms
Pseudo rabies vaccine: can be administered 3-4 times per year, while protecting sows, fetuses, and piglets
Japanese encephalitis vaccine: Immunization once a year in April to prevent summer reproductive disorders
Viral diarrhea vaccines (such as PEDV, TGEV): Immunization with live and inactivated vaccines at 40 and 20 days before delivery, respectively, to protect suckling piglets with maternal antibodies
Precautions
Vaccination only for healthy pigs: poor immune response under disease, stress, or sub-health conditions may lead to side effects
Strictly follow the immunization program, including the age of first immunization, duration of booster immunization, and vaccination interval (interval between live vaccines ≥ 7 days)
Standardized operation: One pig, one needle, vaccine should be warmed up to 20-25 ℃, and drug interference should be avoided (e.g. antibiotics should not be used for one week before and after live vaccines)
