Vaccination methods of Pig Vaccine

Raising pigs is the most common in our daily life, the daily sales of pork is very large, and its market demand is also the largest. Therefore, the breeding area of pigs is also the largest. When raising pigs, we need to do a good job of vaccination in order to ensure the normal growth of pigs. At the time of vaccination, we need to pay attention to its vaccination method, so the editor brought you the vaccination method of pig vaccine today, let's take a look at it!

1. Subcutaneous injection

Subcutaneous injection is now a common method of vaccinating pigs, and most vaccines are vaccinated through subcutaneous injection. Subcutaneous injection is mainly through the injection of vaccine into the subcutaneous tissue of pigs. Then the capillaries in the subcutaneous tissue of the pig absorb it into the blood, and then through the blood circulation to the lymphoid tissue, so that the pig has an immune response. When injected subcutaneously, most of the sites are under the skin of the ear root. However, it should be noted that the absorption of subcutaneous tissue is relatively slow, so oil vaccine is not suitable for subcutaneous injection.

2. Advanced immunity

Advanced immunization is also a major method of vaccination for pigs. Piglets are mainly vaccinated when they eat colostrum. The purpose of advanced immunization is to prevent the vaccine from being affected by maternal antibodies and to ensure that the vaccine virus can occupy the target of virus replication as soon as possible. So that piglets can be stimulated as soon as possible to produce basic immunity in the body. The main purpose of advanced immunization is to vaccinate classical swine fever vaccine and reduce the harm of classical swine fever.

3. intranasal vaccination

Intranasal vaccination is a method of mucosal immunization in pigs. Because mucous membrane is the main portal invaded by most pathogens, more than 95% of infections are caused by mucous membrane. Mucosal immunization can not only stimulate local immunity in pigs, but also establish the corresponding common mucosal immune system function. This system can recognize and respond to antigens inhaled or ingested in the mucosal surface. At present, porcine pseudorabies gene deletion vaccine is mainly used.

4. Other methods

Intramuscular injection is also more common, is to inject the vaccine into the muscle, but to ensure that the length of the injection needle, to ensure that it can be injected into the muscle. Then there is oral vaccination, but because the temperature and pH of the digestive tract of pigs will have a greater impact on the vaccine, so it is not used much. Then the vaccination against asthma in pigs is intratracheal injection and intrapulmonary pigsty. Finally, there is acupoint injection, which is generally carried out when using a vaccine to prevent diarrhea, and its immune response is still very good.

The above is a brief introduction of pig vaccination methods. That's all for today's introduction. This article is for reference only. I hope it can help you all.
