Matters needing attention in Pig Immunization
Pigs are immunized once, twice or more times every year, but pigs still suffer from immunized infectious diseases, causing great losses. What's the reason? This has a lot to do with the matters needing attention that do not pay attention to immunization. As a result, we give a reminder to the vast number of pig farmers.
First, pay attention to buying vaccines from reliable departments. Vaccines or vaccines need to be managed in a special way so that they do not fail. Before purchasing a vaccine or vaccine, it is necessary to confirm whether the department selling the vaccine has a certain technical strength to ensure the effectiveness of the vaccine or vaccine.
Second, pay attention to the failure period of the vaccine or vaccine. When purchasing a certain vaccine or vaccine, you must pay attention to the expiration period, ensure that it can only be purchased within the period of validity, and record the name, manufacturer, batch number, instructions, expiration period, purchasing department and purchase date of the vaccine or vaccine for reference.
Third, pay attention to the advance dilution of the vaccine or vaccine. In rural areas, the number of pigs raised by each household is relatively small, or a single pig farmer can use more than one bottle of vaccine or vaccine, so it is necessary to pre-select the diluted vaccine or vaccine, and then distribute it to users in sterilized vials according to the household dosage. These vials should be brought back in containers containing cold water and used as soon as possible, preferably within 2-4 hours. Never use overnight diluted vaccines or vaccines again. Overnight diluted vaccines or vaccines should be disinfected and disposed of.
Fourth, pay attention to the storage and transportation of vaccines or vaccines. Vaccines or vaccines should be stored and transported at temperatures below 0 ℃ or 2-8 ℃.
Pay attention to avoid diluting vaccines and vaccines in direct sunlight. Vaccines or vaccines should be diluted and distributed in the shade.
Be careful not to vaccinate sick and weak pigs. The immune system of weak pigs is weak, and they can not withstand the attack of vaccine or vaccine, or even aggravate the disease after vaccination or vaccine. Therefore, we should wait for the sick pig to recover before vaccination or vaccine.
Seventh, pay attention to pregnant sows injected with vaccine or vaccine, the operation must be careful, so as not to cause miscarriage.
Pay attention to the application of antibiotics and disinfectants before and after vaccination or vaccine. Antibiotics and disinfectants should not be given to pigs 3 days before vaccination and 3 days after vaccination. Especially in vaccination, antibiotics should not be used within 1 week before vaccination and 10 days after vaccination, otherwise they should be immunized again after 2 weeks of rehabilitation.
Pay attention to the disinfection of instruments and vaccine bottles after vaccination with live vaccines or live vaccines.
Pay attention to the oral administration of the vaccine, mix the vaccine with feed and water taboo acid, can not use rancidity and fermented feed, can not use hot water, hot food. The utensils must be washed with alkaline water before feeding bacteria, and the best size for raising pigs is to feed the vaccine separately, so that each pig can receive the prescribed dose of vaccine. the vaccine must be fed on an empty stomach, preferably in the early morning, after 30 minutes after bacteria feeding.
11. If there is an epidemic around after vaccination or vaccination, the immunity should be strengthened again in order to strengthen the immunity.

High temperature, high humidity, high vigilance against pig parahaemophilus disease
With the increase of temperature and humidity, the incidence of bacterial diseases in pigs will increase, and more attention should be paid to Haemophilus parasuis infection. Haemophilus parasuis only infects pigs and can affect young pigs from 2 weeks to 4 months of age. It mainly occurs before and after weaning and during the nursery stage. It is usually seen in pigs aged 5 to 8 weeks. The incidence rate is 10%~15%. In severe cases, the mortality rate can reach 50%. Acute cases tend to occur first in healthy pigs. Sick pigs fever (40.5~42℃), depression, decreased appetite, dyspnea, abdominal
