Proper vaccination procedure will ensure that your flock is protected against certain health challenges. The following are the procedures and considerations for three different vaccination methods: water, spray and injection. Always remember to follow vaccine manufacturer instructions when storing and preparing the vaccine.
Water vaccination is, in general, the least stressful for the birds and less labor-intensive for farm staff. Be sure to properly store, handle, and mix the vaccine.
Preparing waterlines for vaccine
- Turn off chlorine and run vaccine stabilizer 24 hours before vaccination
Day of vaccination
- Flush tank and pump with clean water
- Turn off water to flock (6:00 am preferably)
- Raise drinkers so the birds can't reach (7:00 am)
- Fill tank with required water to last for 2.5 - 3 hours (normally this is about 25-30% of the daily water consumption)
- Mix vaccine and stabilizer in a clean bucket (used only for vaccinations) and add to tank, stir vigorously
- Include dye to track vaccine water
- Turn on pump and flush drinker lines until dye comes out at the far end of the line
- Dump all bell drinkers into a bucket until blue dye appears, prior to lowering the lines
- Be certain all nipple line cups are blue prior to lowering the lines
- Restrict water access for 1 - 1.5 hours (calculate back from the time the drinkers were raised)
- Lower drinkers to bird level and allow access
- Stir the flock every 15 minutes to encourage drinking
- Vaccine should be consumed in about 2.5 - 3 hours
- Perform 100 bird tongue checks to confirm vaccination accuracy
- Return to normal water sanitation system about three hours after vaccine is finished
Below are some common considerations when performing spray vaccination.
- Provide for 500 or 1000 doses more than the total number of animals to vaccinate (as per the vaccine manufacturer instructions)
- Add water into the bottles and homogenise the solution in the bottle
- Using the syringe, fill up the contents of the bottle from the bottle into the spray container
- Once ready, the vaccination must be done within one hour
- In the summer during hot temperatures, spray the vaccine in the morning when temperatures are the lowest
- Droplets should be uniform
- When spraying, walk across the barn from front to back, covering all areas of the barn
Below are some common considerations when performing injection vaccination.
- Use clean, disinfected syringes and new needles. Change the needles every 100 injections
- Check the that the volume injected corresponds with the amount recommended by the vaccine manufacturer
