First, three kinds of immunization in pigs According to the timing of immunization, immunization can be divided into three types: preventive immunization, taboo immunization and temporary immunization. In order to prevent the occurrence of infectious diseases or related diseases, regular and planned immunization of healthy pigs is called preventive immunization. So vaccination is targeted and planned. However, the recent immunization is to vaccinate pigs that are not infected with the disease when there is an epidemic situation in pigs or a large number of pigs are sick, so as to quickly control the spread of the virus. Therefore, emergency immunization is fast and safe. However, the cost and dosage of emergency immunization are relatively high, and it is rarely used in real life. The so-called snack immunization is to vaccinate pigs in order to avoid epidemics during transportation or introduction.
Second, there are many immunization methods for pigs. Subcutaneous injection can be injected under the ear of pigs or injected on both sides of the neck. Muscle injection is mostly injected in the plump part of pigs. The common inoculation method is skin puncture, which can dip the vaccine into the pig's skin with a seed needle or pen tip. There are also methods of nasal inoculation and oral inoculation.
Three. Precautions for immunization When you first start immunization, you should pay attention to the following situations. Before vaccination, scientific vaccination procedures should be formulated, and farmers should choose scientific and reliable vaccines for their pigs. At the same time, before vaccination, it is also necessary to check whether the bottle in which the vaccine is stored is damaged and whether the color of the vaccine is discolored. When carrying out vaccination work, it is necessary to determine the number of vaccinated pigs and check the health status of pigs in time. After the mission, syringes, vaccine bottles, etc. It should be disinfected before processing.
