What are the points for attention to immunize pigs? Explain the main points in detail!

We all know that vaccination can prevent some diseases. We remember that when we were young, our uncle raised a lot of pigs. After we bought them home, we would invite the staff of the epidemic prevention station to come home to vaccinate the pigs. So what are the points for attention in the process of immunization? The main points are as follows:

1. Determination of vaccination time for pigs

The first immunization time should be determined according to the level of maternal antibody, the pollution of pig farm, the health status of pigs (pay attention to the hidden virus or atypical disease), the variety of vaccine, the duration of immunity and so on.

two。 Quality selection of Pig Immunization Vaccine

The choice of vaccine quality is related to the effect of pig vaccination, so when vaccinating, you must choose vaccines purchased by the government or vaccines with approval numbers produced by manufacturers certified by GMP, and do not buy them in some illegal business units, so as to avoid buying fake and shoddy vaccines. Do not use if expired, discoloration, pollution, mildew, shaky clots or foreign bodies, no or unclear labels, cracked vaccine bottles, lax corks, vacuum-lost vaccines or frozen liquid vaccines are found.

3. Safety Protection of Pig Immunization

(1) vaccination protection of immunized personnel

Immune vaccination personnel need to pay attention to the protection of personnel, require to wear overalls or protective clothing, rubber boots, disposable hats, gloves, wear masks if necessary, no smoking and diet. It must be strictly sterilized when leaving the pigsty.

(2) vaccination of pigs against Baoding.

Pigs can use unarmed Baoding, noose Baoding, recumbent Baoding and so on to reduce the harm of pig dishonesty to immune personnel as much as possible.

4. Aseptic procedure of pig vaccination

(1) Disinfection of instruments

The preventive injection process should be strictly disinfected, the syringe should be washed and boiled, the needle should be changed head by head, and a syringe should not be mixed with a variety of vaccines.

(2) Disinfection of injection site

Pigs need to be injected with iodine tincture or alcohol for disinfection, disinfection should reverse hair disinfection.

(3) change the needle

The needles used for pig vaccination are preferably one needle per pig to avoid cross-contamination, especially in cases of emergency immunization or recessive infection in pigs on the farm.

5. Correct use of vaccine

Before use, you must carefully read the instructions for the use of the vaccine to understand its use, usage, dosage and matters needing attention. In use, direct sunlight should be avoided, and attention should be paid to keeping the normal temperature. The vaccine just taken out from the refrigerator should be warmed up. After opening, it should be used up as soon as possible, and after dilution, it should be used within the time specified in the vaccine instructions.

6. Pay attention to stress response

After the pigs are vaccinated, the feeding management should be strengthened to reduce stress. In case of inevitable stress, anti-stress agents can be added to drinking water, such as water-soluble multi-dimensional, vitamin C, etc., which can effectively alleviate and reduce various stress reactions and enhance immune effect.

7. Points for attention before and after vaccination

(1) one week before and after vaccination, do not use drugs such as adrenocorticosterone that inhibit immune response.

(2) for attenuated vaccines, do not use antimicrobials for a week before and after immunization.

(3) it is forbidden to feed lees, antibiotic dregs (such as lincomycin dregs, oxytetracycline dregs, etc.) and fermented feed 2 hours before and after oral vaccine, so as not to affect the immune effect.

Conclusion: the above is about the introduction of the effect of immunization to pigs, hoping to help farmers in need. This paper is integrated with relevant professional knowledge.
