Pig vaccine injection should pay attention to matters

I. INTRODUCTION The purpose of swine vaccination is to artificially induce the immune system of pigs to produce immunity that is as close as possible to natural infections without any harm caused by natural infections. Effectiveness and safety of swine vaccines are required for the development process. The tests were all required to be approved for listing through various tests and inspections conducted by the original developer and the competent authority. However, after using the vaccine, the farmers had different evaluations of the vaccines used, and the actual values ​​of the differences were thoroughly discussed.
Second, pig vaccine injection should pay attention to matters Pig farms to use vaccine to prevent pig disease before the need to consider the following matters in order to achieve results.
(1) Diseases of pigs diagnosed with diseases other than those known to cause serious industrial losses such as swine fever and pseudorabies must be vaccinated against the disease. Other diseases are caused by the environment and management of the livestock farm itself. There are different and different needs, and these diseases need to be diagnosed first and then consider the above conditions before making choices so as to avoid disappointment due to improper expectations.
(II) Assessment of epidemic situation and loss Pig diseases have certain epidemics, such as onset age, morbidity, and mortality rate. Although the epidemic situation may change due to other factors, the epidemic can basically be used as the cause of the disease. Identification and favorable reference for immune timing selection.
(III) Selection of vaccines As already mentioned, legally listed vaccines need to undergo various tests and inspections by the original manufacturer, the competent authority of the government of the manufacturing country, and the competent authority of the Chinese government. Therefore, the vaccine that is legally listed is selected as the vaccine. The basic guarantee is that due to the different diseases of the target vaccine, the types of induced immunity (cellular immunity and humoral immunity) are also different, so the choice of vaccine is also different. The types of vaccines available on the market can be divided into live attenuated virus (bacteria) vaccines, inactivated vaccines and vaccines, and toxoid vaccines. Different vaccines need different adjuvants to enhance, prolong their effects, and improve their safety. They can be divided into water quality, oil quality, etc. Therefore, it is necessary to understand the protective antigens of various pathogens during vaccine selection. And the type of immunity to choose the vaccine.
(d) The development of immunization and development of immunizing antibodies in pigs should be considered during the appropriate period of immunization and the duration of immunization. And other factors. In the overall epidemic prevention system for swine farms, vaccine prevention and control is an indispensable link, but often there are many diseases in pig farms that need to be vaccinated in similar periods. Therefore, various vaccines are being dragged when planning a vaccination plan. Whether it can be played at the same time in order of priority, whether or not to use mixed vaccines and how many times it needs to be played, how many are needed, etc., all need to be considered.
(5) Precautions to be taken when the vaccine is administered Although the effectiveness of the vaccination depends on the quality of the vaccine product, if the vaccine is kept and the vaccine is not read after reading the instructions of the manufacturer, it often becomes the main cause of the failure of vaccination.
Vaccine preservation: refrigerated at 2 ~ 7°C
The vaccine-injected device should be washed after each use, and physically (such as retort) should be sterilized and then stored in a plastic syringe to be used next time or every time it is replaced.
Find out the number and number of pigs to be vaccinated and calculate the number of vaccines.
Before use, place it in cold water, take it out before the injection and dry it. The freeze-dried vaccine should be diluted with diluent, and the mixed ones should be shaken and mixed evenly.
Unless the specification mentions that the two vaccine products can be mixed, different vaccines cannot be mixed.
A fixed needle was used to draw the vaccine, and other needles were used to inject the pigs.
Different types of needles are used for pigs of different days of age and different injection sites, and the needles must be kept sharp without barbs.
In addition to the need for injection of swine fever at day-old age, the vaccine should be injected into healthy pigs. Allergic pigs should only be injected with epinephrine, and the number of injections should be counted and recorded.
