However, depending on the vaccine, in the past, the focus of the prevention and treatment of swine infectious diseases was to eliminate pathogens and strengthen immunization work. Today, this concept should be changed to recognize the pig's own health and improve disease resistance. This is also the need to achieve healthy farming and food safety.
Do not blindly vaccinate pig farms (households) before vaccinating pigs, first of all to understand the local pig disease epidemic situation, targeted, and reasonable immunity. Injecting too many kinds of vaccines, the pig's immune system will be strongly stimulated, which is not good for pig health and has poor immune effect. Note that any vaccine can only be given to healthy pigs. If a certain epidemic is prevalent in the local area, check whether the healthy pig should be vaccinated, and find a veterinarian to avoid it is in the disease incubation period or invisible infection, resulting in a large-scale epidemic after vaccination.
Strengthen management before and after inoculation 1 week before and after vaccination of pigs, add Astragalus polysaccharide and electrolysis multi-dimensional in pig feed to reduce stress reaction, prohibit the use of antibacterial drugs, but disinfect early or frequently, after vaccination, carefully observe The pig's reaction, prepare the drug, and deal with it in time.
Don't inject expired vaccines. Go to the animal husbandry department to buy vaccines. If the bottle wall is broken, the label is unclear, the record is unknown, it is not kept as required, and the vaccine that is nearing the expiration date should not be used.
Mastering the injection dose of vaccination too much, easy to cause vaccine response, immune paralysis; if the amount of injection is too small, the antigen is insufficient, and the preventive effect is not achieved. Shake well before vaccination, carefully watch the label and instructions for use, and inject as strictly as required. Record the manufacturer, date of inoculation, and dose of inoculation in detail.
Vaccination against pregnant sows is a weakly toxic vaccine that can cause premature birth, miscarriage, and stillbirth in pregnant sows. It is best to inject during the empty period.
Do not vaccinate the newborn pigs too late or too late. By feeding, you can get maternal antibodies, premature vaccination, first, the pigs have poor immune response, and second, they will be interfered by maternal antibodies. Late injections cause maternal antibodies to resolve, increasing the chance of contracting the disease.
Do not inject a variety of vaccines at the same time, pigs need to produce antibodies for a certain period of time. Simultaneous injection of multiple vaccines will interfere with each other and affect antibody formation. When injecting different vaccines, they should be separated by 10 days.
Syringes with strict disinfection needle syringes must be disinfected first, and the unused vaccine should be buried or strictly disinfected to prevent poisoning.
