What are the precautions for giving pigs vaccinations?
Giving pigs vaccinations is an unavoidable issue for every @#@227@#@ household. If applied properly, it will achieve satisfactory results; otherwise, it will cause undue losses to pig production.
1. The pig's health condition should be checked. Sick pigs cannot be injected with vaccines. If a sick pig is injected with a vaccine, it will not only fail to prevent disease but will also worsen the pig's condition. Also, when injecting pigs with vaccines, every pig in the herd should be injected, and none should be missed.
2. It is necessary to accurately grasp the injection timing of vaccines and the immunization period of each vaccine. The time for various vaccines to begin producing immunity in the pig's body and the immunization period are different. For example, swine fever vaccine can produce immunity 4 days after injection, with an immunization period of one year; swine erysipelas vaccine produces immunity 14 days after injection, with an immunization period of 6 months; swine pneumonia vaccine produces immunity 14 days after injection, with an immunization period of 9 months. Before the vaccine produces immunity and after the immunization period is exceeded, pigs may become ill. Therefore, it is necessary to accurately grasp the injection timing of vaccines and the immunization period of vaccines, and promptly inject pigs with preventive vaccines.
3. Vaccines should be used correctly. Live vaccines should be stored at -15°C. Those not stored under the prescribed conditions must not be used. Vaccines should be used within the validity period. Those exceeding the validity period and those not used up on the same day after vaccine preparation must not be used. When using vaccines, inject according to the prescribed quantity, otherwise the preventive effect will be affected. At the same time, when injecting vaccines, disinfection should be done well, such as for syringes, needles, tweezers, etc. Insist on changing the needle after each injection, and disinfect the injection site with 5% iodine tincture.
In addition, after injecting the vaccine, pay attention to observing the pig's feed intake, activity, and defecation, and pay attention to checking the pig's body temperature to see whether there is any abnormality. For sick pigs with more obvious reactions, timely symptomatic treatment should be given.
