Instructions for use of the swine fever vaccine and contraindications
Swine fever is considered a dangerous disease that often leads to the death of animals. Therefore, in order to protect piglets from such a disease, it is necessary to vaccinate. Before the introduction of the vaccine against swine fever, one should read the instructions for its use, as well as its detailed description.
Release form, composition and packaging
Before using a vaccine, you need to familiarize yourself with what components it is made from. The medicine is produced in the form of a powder, which is used for subcutaneous administration. A vaccine is made from an attenuated virus strain. There are two types of this tool. Concentrated and non-concentrated formulations can be found in veterinary pharmacies. They differ in the amount of the virus contained. Concentrated agents are used in medicine much more often.
Outwardly, the medicine looks like a dry whitish or pinkish powder, which must be dissolved with saline before use. During production, the powder for the preparation of the solution is packed into glass bottles, which are hermetically sealed with special stoppers. To prevent the product from scattering, the bottle caps are reinforced with an additional aluminum cap. The volume of such bottles is three milligrams.
This is enough to prepare 10 doses of vaccines. The vials are placed in separate boxes along with instructions for use.
When is the vaccine used?
It should be noted that after the introduction, such a vaccine does not start working immediately. It will take about fourteen hours for the animal to begin to develop immunity to the plague. Moreover, such vaccination is carried out annually, since 10-12 months after the injection of the solution, the immune properties weaken, and the piglet may contract the plague. Therefore, it is used only to improve the functioning of the immune system of animals. The drug has no medicinal properties. It is useless to introduce it to individuals who have already contracted the classic plague.

Instruction for vaccination against classical swine fever
In order for the cultured dry vaccine to help protect piglets from classic plague, it is necessary to understand the instructions for its use. The drug is administered as follows:
- Solution preparation. First you need to prepare a solution that will be administered to the animals. The powder is mixed with sterile saline. At the same time, two milliliters of the drug are consumed per dose of the vaccine. Sometimes the dosage can be increased. It all depends on the age and weight of the pig.
- Vaccine administration. The agent is administered intramuscularly. The inner thigh or the lower part of the neck is selected for insertion. Be very careful when vaccinating. The procedure must be carried out using sterile instruments. A separate needle is used for each pig. It is contraindicated to use the same needle repeatedly.
- Observation. After vaccination, the animals must be observed for two weeks. At the same time, it is recommended that they periodically be examined by a veterinarian and monitored the body's reaction to the injected drug.
Side effects and contraindications
Although the vaccine is safe for piglets, there are a number of side effects and contraindications that you should be aware of before using it. Veterinarians advise against vaccinating sows three weeks before farrowing, as this can adversely affect pregnancy. Also, you should not give the vaccine to too small piglets, whose age is less than one and a half months.
It is contraindicated to use the vaccine, which is in the same syringe, along with other medications and drugs. This can impair the effectiveness of vaccinations.
Some animals start to show side effects after being given the vaccine. Most often, after the injection, the body temperature rises. It rises to 39-40 degrees. Such temperature indicators persist for 2-3 days, after which they begin to drop. However, if the fever persists for a week, you should see your veterinarian. The vaccine may have weakened the pig's immune system and will have to administer additional medications to get rid of the fever.
Storage conditions
To prevent spoilage, the vaccine will have to be stored under suitable conditions. It is recommended to keep the packages with the preparation indoors, protected from sunlight. The air in it should not be too humid, and the temperature should be kept at the level of 3-5 degrees Celsius. In such conditions, the product will not deteriorate for a year and a half. If the drug has been kept in unsuitable conditions for a long time, it will have to be disposed of.
Conclusion
Some farmers are faced with swine fever, due to which many of the animals on the farm die. To keep them safe, you need to vaccinate regularly. However, before that, you should familiarize yourself with the indications for the administration of the vaccine, as well as with the features of its use.
