How to use poultry vaccine properly

Bacteria (bacteria) seedlings are an important tool for the prevention and control of infectious diseases. Only proper use can make the body produce enough immunity, so as to resist the invasion and pathogenic effects of foreign pathogenic microorganisms. In the case of poultry (bacteria) vaccines, the following general knowledge must be understood during use. 1. Vaccination (bacteriophage) seedlings are only used for the prevention of the health of the flock of poultry, and they have no therapeutic effect on infected birds, and the immunization effect of emergency vaccination cannot be fully guaranteed. 2, must develop the correct immunization program. Since the species, age, maternal antibody levels and the type of disease (bacteria) seedlings of birds are not the same, it is advisable to Monitor and monitor the level of antibodies and dynamics of the flock prior to the use of the disease (bacteria) seedlings, or to refer to relevant experts. , Manufacturers recommended immunization procedures, and then according to the specific circumstances, together with experienced veterinarian division to develop immunization procedures. 3, the correct use of disease (bacteria) seedlings. At present, there are two major types of bacterin (bacteria) seedlings: attenuated vaccines and inactivated vaccines. The bactericidal seedlings in attenuated vaccines need to be cryopreserved and transported, otherwise they will fail. Inactivated vaccines include oil emulsions, propolis preparations, aluminum hydroxide preparations, etc., and can be stored at room temperature, but the best preservation effect is 2°C-8°C. Be careful not to be exposed to sunlight or freezing, and to recover before use. To room temperature; should carefully check the name of the disease (bacteria) seedlings and the prevention of disease is consistent with whether it is valid within the use of the inoculation equipment such as syringes, needles, dropper, etc. should be cleaned, disinfected and kept dry; diluted vaccine (bacteria) seedlings In this case, only specific diluents such as Marek's disease vaccine-specific dilutions should be used and the prescribed methods should be followed. Inactivated bacteriophage should not be diluted or blended; Inoculate the bacterin (bacteria) seedlings, and ensure that the inoculation dose is accurate. Do not arbitrarily increase or decrease the dose; use fixed needles when sucking out bacterin (bacteria) seedlings, and not use needles that have been in contact with birds, and the sterilized bacteria have been sucked out. ) Seedlings can not be re-injected into the bottle to prevent contamination. The diluted vaccine should be used up within a limited time. Unused vaccines should be disinfected and destroyed; they must be used when inoculated with attenuated vaccines. A few days before and after Internally, stop giving all kinds of antibacterial drugs; two or more than two kinds of epidemic (bacteria) vaccines can not be mixed arbitrarily or at the same time, so as not to affect the immune effects they deserve, produce toxic and side effects and aggravate the stress response; poultry only before slaughter No oil adjuvant or aluminum hydroxide adjuvant vaccine should be given within 6 weeks. 4. After inoculation of the disease (bacteria) seedlings, it is necessary to strengthen the feeding and management of the flock and reduce the impact of stress factors on the birds. The use of attenuated vaccines and inactivated vaccines is also a weak stress for poultry, and it usually takes about 1-2 weeks after inoculation of the vaccine to produce a certain degree of immunity. During this period, more detailed management work must be done. Do not think that the use of Miao is finished. It is appropriate to add some nutrients such as vitamin C to the feed in the feed, add anti-stress drugs to the drinking water, reduce heat, congestion, humidity, poor ventilation, excessive concentration of harmful gases, etc. The influence of factors to ensure that the body successfully generates sufficient immunity. Pay special attention to prevent the infection of pathogenic microorganisms, otherwise it may lead to immune failure.
