NEWCASTLE-BRONCHITIS VACCINE

B1 Type, LaSota Strain, Mass & Conn Types, Live Virus

Description

This live virus vaccine, is prepared from the proven Clone 30 strain of Newcastle disease virus and the regular Massachusetts and Connecticut types of bronchitis virus. The viruses have been propagated using SPF embryonated eggs.

Intervet’s research team cloned several lentogenic ND virus strains from separate possible sub-populations within these strains. These clones were then extensively tested for immunogenicity and reactivity. One clone, designated ND Virus Clone 30, was selected and proven to be of the same order of reactivity as the classical Hitchner B1, but provided considerably better protection.

Combovac-30 Indications For Use

Coarse Spray or Drinking Water - Vaccination of healthy chickens two weeks of age or older to aid in the prevention of Newcastle disease and Massachusetts and Connecticut types bronchitis.

Vaccination Programs

Many factors must be considered in determining a sound vaccination program for a particular farm or poultry complex. To be fully effective, the vaccine must be administered properly to healthy, receptive birds maintained in a proper environment under good management. In addition, the response may be influenced by the age of the birds and their immune status. Seldom does one live virus vaccination under field conditions produce lifetime protection for all individuals in a given flock. The level of immunity required will vary with operational practices and the degree of exposure. Therefore, a program of periodic revaccinations may be necessary.

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 tap 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 for drinking water or coarse spray use 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 the water from the chickens until they are thirsty. Withholding periods will vary from 2 to 8 hours according to age of chickens and weather conditions.

3. Scrub waterers and rinse thoroughly with fresh, clean water. Do not use disinfectants for cleaning waterers.

4. Mix rehydrated vaccine with clean, cool, non-chlorinated tap water in accordance with the chart below:

As an aid in preserving the virus, 100 g (3.2 oz.) of non-fat powdered milk may be added to each 38 liters (10 U.S. gal. or 8 Imp. gal.) of water used for mixing vaccine. Add the dried milk first and agitate thoroughly. Then add the rehydrated vaccine from the vial and mix thoroughly.

5. Distribute the vaccine solution, as prepared above, in the waterers provided for the chickens. Avoid placing waterers in direct sunlight.

6. Provide no other drinking water until all the vaccine-water solution has been consumed.

Coarse Spray Vaccination

1. Initial spray vaccination should be coarse spray, i.e. Hardi®.

2. Do not use any disinfectants or skim milk in sprayer.

3. Use sprayer only for administration of vaccines.

4. Shut off all fans while spray vaccinating. Turn on fan immediately after spraying. Be careful in hot weather.
