Vaccination is an effective method to stimulate the animal body to produce specific resistance to transform susceptible animals into susceptible animals. Planned immunization is still one of the important measures to prevent and control livestock and poultry infectious diseases.
According to the transmission mode, invasive route and operability of each pathogenic microorganism, there are many methods for vaccination, such as nasal drops, eye drops, drops, sprays, drinking water, and spices. Specific to each vaccine, there may be one or more inoculation methods, but in actual production, different immune methods are often selected in consideration of operability, convenience, economy, and different growth stages of livestock during immunization. It is not uncommon for immunization to fail due to improper vaccination methods, even causing serious adverse reactions or the onset of infection. Therefore, different vaccines should be selected according to the actual production and their own conditions, in order to receive a good immune effect.
Drinking water immunization has been applied by most farmers because of its advantages of convenience, effort, and immunity. However, many breeders still do not fully understand the operating procedures and detailed implementation details of drinking water immunization, and cannot fully exert the effect of drinking water immunity, thus causing immune failure. Therefore, if you want to make drinking water immune to receive the best results, you must follow the following principles:
Rinse the water system and drinker thoroughly before drinking water, but do not rinse with detergent and disinfectant.
3 days before and after the immunization of drinking water, add an appropriate proportion of vitamin electrolytes, such as Vibo 100, etc. in the drinking water to reduce the immune stress.
Add 0.3% to 0.5% non-fat dry milk or a special vaccine protectant to drinking water, such as Rippo's “Zhengboâ€, and then add the vaccine to reduce the impact of heavy metal ions in the water on the vaccine.
Water for immunization should be deep well water or cold boiled water. Drinking water should not contain any substances that inactivate the vaccine, such as chlorine, zinc, copper, iron and other ions; if using tap water (in some tap water contains bleach) must be boiled for 3 minutes to 5 minutes, and then put it overnight before use.
In order for all chickens to have a thirst to drink into the vaccine water, they must be stopped for 2 hours to 4 hours before immunization (depending on the season and Shervin). Generally speaking, the summer is short (1 hour~3 Hours) long winter (3 hours to 4 hours).
According to the difference in the effect of chicken body on the vaccine response during the day, drinking water immunity is best performed in the morning to reduce the impact of the external environment (sunshine, temperature) on the vaccine.
Drinking fountains are adequate and reasonably placed. Each chicken should be provided with a drinking trough. At the same time, the chickens should be driven to make sure that each chicken can drink vaccine water. When the drinking fountains are insufficient, the vaccine can be carried out in batches. Used now to prevent the vaccine from failing over time.
When drinking water is immunized, the dose of vaccine should not be too large, generally 2 times to 4 times, so as to prevent individual chickens from drinking too much and causing adverse effects.
Diluted vaccine water should be appropriate, not too much or too little, according to the size of the immunized chickens, the length of time, the temperature of the water temperature to determine the amount of drinking water, vaccine water should be finished in 1 and a half hours to 2 hours . The water consumption of each chicken is generally as follows (for reference only):
7 to 14 days of age each 10 ml to 25 ml; 19 days to 25 days of age 35 ml to 45 ml each; 50 days after each 50 ml to 60 ml.
In order to accurately determine the amount of drinking water required, the amount of drinking water in the birds in the same period of time can be determined continuously after determining the age of immunization, and the average amount is used to determine the amount of drinking water.
When the vaccine is turned on, it should be carried out in water to prevent external contamination. After pouring into the water, stir it with a clean wooden stick or glass rod to mix the vaccine and water. Quickly add the vaccine to the drinking fountain and try to keep the chickens drink as much as possible. Vaccine water.
For larger flocks, vaccination may be preceded by partial vaccination. Specific methods: Dissolve 2/3 of the vaccine in 2/3 of the drinking water for chickens to drink. After the drink is finished, dissolve the remaining 1/3 of the vaccine into the remaining 1/3 of drinking water and add drinking water. In the device, this can not only reduce the vaccine failure, but also help to grasp the amount of drinking water. However, in order to ensure that more than 2/3 of chickens can drink vaccine water at the same time, this method must be used to ensure sufficient water levels.
After dilution, the vaccine should not be exposed to sunlight. To ensure that the vaccine is fully absorbed in chickens, it is best to add feed after 1 hour after the vaccine is finished.
2 days before and 3 days after immunization, disinfection with water or spray disinfection is not allowed, and antiviral drugs or antibacterial drugs cannot be used.
Drinking fountains cannot be made of metal. It is best to use nontoxic plastic or enamel containers.
Before the diluted vaccine water is consumed, no other drinking water is available until the immunized chickens drink water after drinking the vaccine.
