FIELD VACCINATION 3.1 Spray Vaccination with Backpack Sprayer System (cont.) Sprayer Maintenance » Fully charge batteries prior to use. » Change batteries after spraying 114 liters (30 gallons) of liquid or when the sprayer has been sitting unused for an extended time. » Thoroughly rinse the tank with 3.8 liters (1 gallon) of distilled water at the end of each day or if changing vaccines. COBB VACCINATION MANAGEMENT GUIDE » Remove and clean or replace the filter as needed. » Clean the outside of the sprayer using a damp cloth and a mild detergent. » Rinse the tank and pump thoroughly by spraying distilled water through the sprayer after using a bleach solution.
Use a final rinse of isopropyl alcohol and spray before emptying and storing. » Store the sprayer upside down in an area where it will not be exposed to temperature extremes. » Periodically check all hoses and connections for signs of wear. Replace as needed. Before and during vaccination, one person should walk ahead of the vaccinators so that the flock will naturally move apart and keep the birds from piling against the back wall. This division of the flock will help ensure a more uniform vaccination of the birds and will reduce stress for the flock during the process.
After vaccination the farmer or service technician should walk through the house to adjust lighting and equipment if needed and to verify that the bird behavior and distribution have returned to normal. ANIMAL WELFARE TIPS 15
