FIELD VACCINATION 3.2.3 Using a Medicator or Proportioner A medicator or a proportioner can be used to deliver vaccine through the drinker lines to the birds. Medicators and proportioners are connected inline to the drinking system. Before Vaccination » Flush the drinker lines with fresh water to eliminate residues. Vaccine Preparation » Calculate the amount of water needed so the vaccine is consumed in about 90 minutes. This amount should be approximately 30% of the daily water intake. COBB VACCINATION MANAGEMENT GUIDE » Prepare the vaccine following manufacturer’s instructions and guidelines in section 3.2.
Mix vaccine into a container or containers large enough to hold the required volume of mixed vaccine. » Prime the medicator with the vaccine solution. Bypass or remove water filters during vaccination. Vaccine Administration » Open the end of the drinker line. One staff member must observe the water coming out of the end of the drinker line until the dye solution (the vaccine) is visible (see photos page 20). When the dye is visible, close the end of the drinker line. » Lower the drinker lines to allow the chickens to consume the vaccine.
» Every 15 to 20 minutes, check the vaccine solution to ensure the pump is operating correctly and that the vaccine is still flowing through the drinker lines. 21
