Vaccination precautions for swine herds

When raising pigs, it is inevitable that pigs get sick. Pig farmers will vaccinate pigs in order to effectively prevent and control changes, but many farmers lack the knowledge of vaccination and often fail to vaccine. bring huge losses to the whole pig farm. So what should pigs pay attention to when they are vaccinated? Let's get to know it.

1. Vaccine selection and purchase

When farmers vaccinate pigs, they should investigate and study the local epidemic diseases and make reasonable immunization procedures, which should not be vaccinated blindly, resulting in unnecessary waste. When choosing and purchasing a vaccine, it is necessary to formulate the dosage of the vaccine according to the breeding quantity and the vaccine period, and choose to go to the formal department to buy the vaccine. It is not suitable to buy the vaccine whose bottle wall is broken, the bottle label is unclear or the record is not clear. Vaccines that are about to expire should not be purchased.

2. Pay attention to the amount of injection

The amount of vaccine injection is also more important, too much injection will often cause vaccine response, too little injection will lead to the reduction of antigen, can not achieve the importance of disease prevention. Shake the vaccine fully before use, so that its sediment is fully mixed evenly, strictly according to the bottle label and instructions during injection, and make relevant records to avoid leakage or repeated injection.

3. Injection object

The vaccine itself is a weak virus, so we should pay attention to the object when injecting. The health status of the pig herd will affect the success rate of the vaccine. When a certain disease occurs in the pig herd, the vaccine will not only not play the role of immunity. On the contrary, it will also lead to the death of pigs, or cause the spread of the epidemic. In addition, it is not suitable to vaccinate sows, which will cause miscarriage or stillbirth in sows. It is best to inject vaccines one month before mating, which can not only prevent miscarriage and stillbirth, but also pass the resistance of piglets. Pay attention to the time of piglet injection, the resistance of piglets is poor, should not be injected prematurely, early injection will interfere with its maternal antibody, generally in 20-25-day-old injection, 60-day-old to strengthen an immunity.

4. Pay attention to disinfection

Vaccination is to do adequate disinfection work, for needles, syringes, tweezers and other appliances must be disinfected in advance, each injection to change a needle, after the immune injection to carry out large-scale disinfection work. In addition, when injecting the vaccine, we should not pay attention to the two kinds of vaccine at the same time, otherwise the vaccines will interfere with each other and affect the formation of antibodies, and the effect will often be poor. Generally, it is necessary to inject another vaccine at intervals of more than 7-10.
