The most complete immune procedure in pig farm

I. Pig farm immunization procedure

1. 7-day-old injection of mycoplasma pneumoniae attenuated lyophilized vaccine (for pigs with purified disease)

2. Intramuscular injection of 2ml polyvalent inactivated vaccine against edema disease of piglets at the age of 15 days

3. At the age of 20 days, 4 doses of attenuated classical swine fever vaccine were injected intramuscularly:

4. 30-day-old injection of inactivated vaccine against blue ear disease (PRRS) (used in positive pig farms) (used according to instructions)

5. At the age of 35 days, the inactivated vaccine of foot-and-mouth disease was selected. (use according to the instructions)

6. At the age of 40 days, paratyphoid vaccine (live vaccine of Salmonella cholerae C500 attenuated strain of porcine cholera) must be injected intramuscularly or orally.

7. At the age of 56 days, 4 doses of attenuated classical swine fever vaccine were injected intramuscularly. (strengthened seedlings)

8. At the age of 60 days, 1 dose or 4 oral doses of Streptococcus suis attenuated strain freeze-dried live vaccine were injected subcutaneously or orally.

Description:

1. Type O foot-and-mouth disease oil emulsion inactivated vaccine is used in areas threatened by foot-and-mouth disease. More than 50 kilograms of pigs are injected with 3 milliliters; 25-50 kilograms of pigs are injected with 2 milliliters; 10-25 kilograms of pigs are injected with one milliliter.

two。 Inactivated vaccine or attenuated vaccine of porcine transmissible gastroenteritis epidemic diarrhea is injected every October.

Note:

1.。 Attention should be paid to the effect of drugs on the immune effect of the vaccine before and after the use of the vaccine. Special attention should be paid to immunosuppressive drugs and antimicrobial drugs that can kill and inhibit the vaccine.

two。 When allergy occurs, 0.2-1 ml epinephrine is injected subcutaneously or intramuscularly, and 10 times dilution is required for intravenous injection.

3. Vaccine immunization should usually be carried out in the healthy state of pigs, and the immunization procedure is often adjusted by many factors such as the health status of pigs. Adjust the immunization procedure under the guidance of a veterinarian. Classical swine fever and foot-and-mouth disease should be forcibly immunized by the state, and the vaccine can be collected directly from the local veterinary prevention station or asked to be injected free of charge.

4. In order to make the vaccine work better, effective management measures must be taken to reduce the pathogenic microorganisms in the environment.

5. The above immunization procedure is only a guide, and each farm should be selected according to the disease status and existing problems of their own pig farms.

6. The period of lactation is a key link. In order to reduce the chance of piglets being infected by sows, isolation early weaning or drug early weaning can be used and weaned within 4 weeks.

7. The guidance is more comprehensive and detailed, but not every pig farm or pig farmer must follow it.

? two。 Pig farm health care procedure

1. 1-3 days old. Injection or oral injection of anti-dysentery gold needle 1 ml / head and Xianrekang 1 ml / head. Just once.

2. 7-10 days old: "Ailexiao" or "Qingwen Baidu Powder" (which can be added to the feed according to the proportion of 0.2-0.4%) was added to the diet of suckling pigs to induce food.

3. 12-14 days old: oral or injection of antidysentery gold needle 2 ml / head, once. Add "Shuqite" or "Qingwen Baidu Powder" to the feed for three days; castration.

4. 18-22 days old: oral "Zhi dysentery Golden Needle" or "Qianrekang" for three days.

5. 28-30 days old: in feed or drinking water, add "Fuzheng jiedu Powder" or "Lvyuanhong" or "Qingwen Baidu Powder" once a day for three days. The effect of preventing edema disease is better than that of edema disease vaccine. You can be weaned at this time.

6. 38-40 days old: ① was treated with Fangtong "Changshun" tablet or deworming powder once, and "Qingwen Baidu Powder" was taken orally at the same time. ② also adds "Eloxiao" or "Shuqi" to the feed to prevent a variety of bacterial and viral diseases.

7. 50-60 days old: add "Ailexiao" in the proportion of 0.2% in the feed, and add "Qingwen Baidu Powder" according to 0.1-0.15g / kg to prevent streptococcosis, toxoplasmosis and piglet edema disease for 10 days.

8.61-out (fattening period): ① was fed with "Ailexiao" for 35 days in the first 15 days of each month, and "Qingwen Baidu Powder" plus Shuqi for about 5 days after 15 days, in order to improve immunity and prevent viral diseases such as blue ear disease, circovirus, influenza, digestive tract, respiratory tract, eperythrozoon, streptococci and blood infection. ② was treated with Fangtong Escherichia tablets or deworming powder every 40 days or so. ③ was cross-used with "double-stranded quaternary amine complex iodine disinfectant" and Fangtong Wudi disinfectant to disinfect the pig house and environment at least twice a week.

Another immunization program:

(1) Suckling piglets

1. Asthma: the standard immunization is the first immunization on the 21st day, and then immunized again 3 weeks after weaning (only once is recommended for some vaccines). If the asthma in the pig farm is more serious, the first exemption can be advanced to 10 Mel for 14 days.

two。 Laner's disease (PRRS, which must be immunized only when the presence of Laner's disease has been confirmed in this field). The first immunization was given on the 21st day, and the second immunization was performed 3 weeks after weaning. If you are infected at an early stage, you can give the first exemption as early as 8-10 days.

3. Porcine atrophic rhinitis: in addition to inoculating sows, piglets can be immunized for the first time in 21 days and immunized again 3 weeks later.

4. E. coli: if the pig farm has edema disease, the piglets need to be immunized before weaning.

(2) weaning and growing pigs: according to the actual situation of each farm, according to the time of occurrence of the disease, and according to the secondary immunity to lactating piglets, immunity at this stage shall be carried out at an appropriate time.

Mainly include: classical swine fever, foot-and-mouth disease, pseudorabies, Escherichia coli (edema disease), Salmonella, infectious pleuropneumonia, Pasteurella multocida, porcine erysipelas, streptococci and other vaccines.

(3) pre-breeding sows and reserve sows:

During the first immunization, immunization should be carried out 5 and 2 weeks before mating, respectively.

Mainly include: swine erysipelas? Parvovirus? Leptospira

The following diseases can also be immunized at this stage.

Classical swine fever

? Foot-and-mouth disease (if the disease occurs in suckling piglets, the sows can be immunized before giving birth)

? Pseudorabies (if the disease occurs in suckling piglets, the sows can be immunized before giving birth)

? Blue ear disease (PRRS, immunized only when the presence of blue ear disease has been confirmed in this field)

(4) pre-parturition sows and reserve sows-the following immunization can be given to sows before delivery to increase the antibodies in colostrum. Parturient sows should be immunized twice 5 and 2 weeks before delivery, and parturient sows should be immunized once 2 weeks before parturition.

? E. coli? Constrictive rhinitis? Transmissible gastroenteritis
