1. Drinking water immunization
- ideal to be used1Flocks over the age of weeks in order to obtain immunity through uniform drinking water. Although simple and easy to do by drinking water, there is also a risk of immune failure due to poor management due to vulnerability to flock status and drinking water systems.
- Before immunization3~4The water line is cleaned every day, and the drinking water pipe is carefully and thoroughly cleaned with high-pressure water in the direction of reflux, and then continuously3~ 4Days in drinking water to add acidifier.
- Before drinking water immunization1Day, check the drinker and nipples are clean and normal, at this time in the water pipe can not be disinfected, disinfection can lead to vaccine inactivation. Ensure that all water disinfection systems are turned off and that there is only clean water in the water pipes.
- Make the flock thirsty before giving the vaccine30-90minutes or longer(Depends on the climate and the degree of thirst).
- Thoroughly empty the plumbing system to ensure that all water is drained, especially the bottom of the tank and the lowest part of the plumbing (retained water where the waterline is bent).
- -General drinking water immunization predicts the amount of drinking water is about the amount of drinking water the day before.1/7.
-Dissolves in every liter of water2. 5grams of skimmed milk powder( Avoid the formation of clumps), the vaccine dose should meet the number of chickens immunized according to the age of the day. Completely mixed( With plastic stirring rod)Vaccine solution. Keep the vaccine solution cool and avoid exposure to direct sunlight.
-Check whether all drinkers and nipples are filled with milk water. In the special case of using nipple drinkers, open the water pipe at the other end to allow the air enclosed in the pipe to be discharged to ensure that the vaccine solution reaches the other end.
-Check the entire chicken house to ensure that all chickens are drinking the vaccine solution.
-After drinking, open the water pipe valve and turn to normal drinking water.
-All equipment used for the preparation of vaccine solutions should be clean and free from signs of disinfection.
-The quality of the water should be in line with human drinking standards, mineral content does not exceed the standard.
2, spray
-This method is carried out by spraying the vaccine solution, and the sprayed particles should contain a sufficient number of live vaccine particles in contact with the ocular mucosa and the respiratory tract in order to proliferate there. The immune response is initially local and then systemic
-In particular, the spray method is suitable for lower virulence virus vaccines, and the first or repeated immunization by respiratory tract( such as newcastle diseaseIVDepartment andC30Infectious bronchitisH120Other Vaccines).
-In all cases, immunization should be carried out in accordance with the manufacturer's instructions, and vaccines that are not suitable for spray immunization are not recommended.
-The effectiveness of spray immunization and the severity of respiratory reactions after vaccination depend primarily on the size of the droplets in contact with the eyes and respiratory tract of chickens. Generally speaking, the droplets are determined by the structure of the machine equipment, and the droplets are determined150μ30μ is not equal, the smaller the droplet, the longer the duration of sealing is required, otherwise there is no sufficient droplet adhesion on the mucosa, which will easily lead to insufficient immunity.
According to the equipment and temperature conditions used, the amount of water should be adjusted appropriately so that the spray of the chickens continues15-20Minutes.-Multi-channel spray (manual and equipment spray at the same time).A successful spray should make the head of the chicken all wet.
Chicken immunization is actually an important part of the breeding process, good chicken seedlings with good immunization, in order to obtain good immunity, so as to improve the production efficiency of laying hens.
