The current hot and humid weather provides better external conditions for the survival of animal pathogens in vitro and poses a greater threat to the health of the herd. Under the situation that the price of pigs is climbing, it is crucial to strengthen the prevention and control of infectious diseases in pig farms, especially export pig farms. (1) Scientifically formulating immunization procedures The farm should analyze the epidemic pattern and characteristics of the epidemic according to the epidemic situation in the region and the farm over the years, and determine the type of vaccine needed. All types of infectious diseases that are more popular in the local area and have a major impact on production and reproduction are all vaccinated. Different vaccination strategies are adopted according to the different uses of pigs and different age groups. Before the inoculation, blood samples can be taken to the Jiuding Pig Disease Diagnosis Laboratory for testing. We can provide a scientific diagnosis and immunization program according to the specific conditions of the farm. Then you can follow the diagnosis and the plan. In order to prevent two or more infectious diseases, it is possible to use a combination vaccine according to the situation, that is, a single vaccine that can produce resistance against various diseases. However, for infectious diseases that are more prevalent in many areas (such as swine fever), it is best to use a single vaccine, that is, a single vaccine that is resistant to the disease. (2) Strengthen the pre-vaccination inspection and preservation of vaccines Before inoculation of live animals, it is necessary to check and confirm from two aspects. First, carefully check the vaccine for instructions. It is necessary to select a vaccine with the national competent authority to approve the production number or the import approval number, and carefully check whether the inside and outside of the vaccine is complete and whether the vaccine label is clear. Check the manufacturer, date of manufacture, and expiration date of the vaccine, and check whether the container has cracks, whether the seal is tight, whether there is any foreign matter in the bottle, clot, freezing, sedimentation or turbidity. The second is to observe the health of the pig. Pigs with frailty, morbidity, and incubation period are not suitable for vaccination, and pigs in late pregnancy should be used with caution or not. (3) Strictly regulate the method of inoculation Vaccination methods include nose drops, eye drops, water, spray, subcutaneous injection, and intramuscular injection. Among them, intramuscular injection is most commonly used. When using intramuscular injection, the first is to choose the appropriate size and length of the injection needle. Generally, the lyophilized vaccine uses a No. 7 needle, and the oil emulsion vaccine uses a No. 12 needle. Second, syringes and needles must be autoclaved as required or selected unused syringes. Third, the injection site should be correct. The injection of live pigs is generally selected from the back of the neck, the inner thighs or the buttocks (as shown below), and the direction of the needles is perpendicular to the skin. Fourth, the injection site should be disinfected. Before immunization, 75% alcohol or 5% iodine should be used to wipe around the needle site of the body. (4) Nursing after vaccination In the short-term injection of vaccines, very few pigs developed an allergic reaction, which showed uneasiness, sudden fall, vomiting, and salivation. Should pay attention to observation, timely rescue, rescue method can be injected with 1-3 ml of 0.1% adrenaline muscle. At the same time, it is necessary to strengthen the management of feeding. Some slight reactions after injection of seedlings, such as reducing food, are normal phenomena and can be restored without treatment. If the reaction is severe for a few days, if the body temperature rises, you can inject 10 ml of fresh egg white into the muscle or injection.
