Attention! Seven taboos of pig vaccination to avoid blind vaccination
When purchasing vaccines, the vaccine dosage plan should be made according to the number of pigs fed and the immunization period of the vaccine
1. avoid the injection of outdated vaccines
When purchasing vaccines, the vaccine dosage plan should be made according to the number of pigs fed and the immunization period of the vaccine, and the vaccine should be purchased in the regular livestock sector. Do not buy vaccines with broken bottle walls, unclear bottle labels or unknown records, and do not buy vaccines that are not retained as required and are approaching the expiration date.
2. avoid blind vaccination
Before immunizing pigs, professional pig farmers and pig farms should first investigate and study the laws and conditions of the epidemic of local pig diseases, formulate reasonable immunization procedures, and be targeted.
3. avoid giving pregnant sows vaccine
The vaccine is a weak virus that can cause miscarriage, premature birth or stillbirth in sows. For breeding sows, it is best to inject vaccine one month before mating, which can prevent sows from abortion caused by vaccination during pregnancy, and can improve the immunity of piglets.
4. avoid too much or too little vaccination
Too much vaccine injection often causes vaccine reaction, too little is insufficient antigen, can not achieve the preventive effect. The vaccine should be shaken well before use so that the sediment is mixed evenly. Look carefully at the bottle label and instructions for use, give injections strictly according to the required dosage, and specifically record the injection dosage, date, vaccine origin, factory time, etc. to prevent leakage.
5. avoid giving piglets vaccine too early
Newly born piglets can obtain maternal antibodies from the mother (if the sow has been immunized prenatal), which can effectively resist diseases. In addition to special circumstances (such as advanced immunization), they are generally vaccinated early. If the premature injection of vaccine, one is the poor immune response of piglets, the two is to interfere with the maternal antibody. Therefore, piglets injection of classical swine fever vaccine should be at the age of 20-25 days of age first free, 60 days of age need to strengthen the immune once.
6. avoid injection when the disinfection is not strict
When the vaccine is injected, it is necessary to make full disinfection preparation. The injection device, needle, tweezers, etc. must be disinfected in advance. The alcohol cotton ball should be prepared 48 hours ago. During immunization, a pig should be replaced with a needle for each injection to prevent poisoning and bacteria. At the same time, before and after the pig immune injection, but also to avoid large-scale disinfection flow and the use of antibacterial drugs.
7. avoid two vaccines at the same time
After vaccination, pigs need a certain amount of time to produce antibodies. If the two vaccines are injected at the same time, the vaccines will interfere with each other, affecting the formation of antibodies, and the effect is often poor. Therefore, two different vaccines should be injected for 5-7 days, preferably more than 10 days.
