What do you need to pay attention to for immunization of sheep? In the process of breeding, it is very important to immunize the flock, and some flocks have various adverse reactions during immunization. Therefore, in order to avoid this, the next small series will come. Let me talk about the immunization precautions of the sheep and hope to help everyone.
1. Maintain the temperature and humidity of the breeding house, and require the farm house to have proper illumination and good ventilation. At the same time, it is necessary to do daily disinfection management.
2. Develop a scientific and rational immunization program and select a vaccine with appropriate virulence or strain.
3. Before immunization, the immunization should be carried out in strict accordance with the instructions for use of the vaccine. The injection site should be accurate, the inoculation method should be standardized, and the inoculation dose should be appropriate.
4. Conduct a health check on the flock before immunization to understand its health. For morbidity, mental, appetite, abnormal body temperature, thin, young, old, late pregnancy sheep, do not vaccinate or suspend vaccination.
5. The quality, storage conditions and shelf life of the immunized vaccine should be carefully checked. If necessary, a small group of animals should be inoculated first, and then a large group of immunizations.
6. Before the immunization of the flock, avoid the sheep from being subjected to stress reactions such as cold, transfer, transportation, dehydration, sudden refueling, noise, and fright. 3-5 days before and after immunization, add instant multi-dimensional, or VC, VE, etc. in drinking water to reduce stress response.
7. Provide nutritious and balanced high-quality feed to the sheep before and after immunization to improve the non-specific immunity of the sheep.
8. For sheep with a history of allergic reactions, before the injection of the vaccine, 5 mg of 0.1% epinephrine hydrochloride is injected subcutaneously before the vaccine.
