BRONCHITIS VACCINE

Delaware Type, Modified Live Virus

DIRECTIONS FOR USE, READ CAREFULLY

Description

This vaccine is formulated from a modified strain of Delaware Type Infectious Bronchitis Virus. The virus was received from the University of Delaware and was modified for high immunizing capability and milder reaction, i.e. snicking. The virus is grown under exacting standards of quality control in eggs produced by healthy chickens in closely supervised flocks.

Shor-Bron-D Indications For Use

This product has been shown to be effective for the vaccination of healthy chickens 1 day of age or 2 weeks of age or older against infectious bronchitis virus, Delaware type. Duration of immunity has not been established. For more information regarding efficacy and safety data, see productdata.aphis.usda.gov.

Vaccination Programs

Many factors must be considered in determining the proper vaccination program for a particular farm or poultry operation. To be fully effective, the vaccine must be administered to healthy receptive chickens held in a proper environment under good management. In addition, the response may be modified by the age of the chickens and their immune status. Seldom does one vaccination under field conditions produce complete protection for all individuals, in a given flock. The amount of protection required will vary with the type of operation and the degree of exposure that a flock is likely to encounter. For these reasons a program of periodic revaccination may be required.

Preparation Of Vaccine

FOR DRINKING WATER OR COARSE SPRAY USE

DO NOT OPEN AND MIX THE VACCINE UNTIL READY TO BEGIN VACCINATION. USE VACCINE IMMEDIATELY AFTER MIXING.

1. Remove the tear-off seal and stopper from the vial containing the lyophilized vaccine.

2. Carefully pour clean, cool, non-chlorinated water into the vaccine vial until the vial is approximately two-thirds full.

3. Insert the rubber stopper and shake vigorously until all material is dissolved.

4. The vaccine is now ready to be applied as per label in accordance with the directions below. For best results, be sure to follow directions carefully!

Drinking Water Administration

FOR CHICKENS TWO WEEKS OF AGE OR OLDER

1. Do not use any disinfectants in the drinking water for 48 hours before vaccinating and 24 hours after vaccination.

2. Withhold water from the chickens until they are thirsty.

3. Calculate the water volume needed so the vaccine will be consumed in approximately 2 hours.

4. Optional: as an aid in preserving the virus, add a vaccine stabilizer to the stock solution or to the tank containing clean, cool, non-chlorinated water. Agitate thoroughly. Follow the manufacturer’s rate of administrations and wait time.

5. Add rehydrated vaccine from vial to the water and mix thoroughly.

6. Turn on tank valve or automatic dosing system.

7. Provide as sole source of drinking water until all vaccine-water solution has been consumed.

Coarse Spray Administration

FOR CHICKENS ONE DAY OF AGE OR OLDER

Calculate the water volume needed. For example, a machine which dispenses 21 ml to a box of 100 chickens - total volume for 10,000 doses is 2,100 ml of non-chlorinated water. For coarse spray in chicken houses, follow manufacturer’s direction for the particular spray machine. Add rehydrated vaccine and mix thoroughly.
