Description
POLYBRON® B1 is formulated from carefully selected strains of infectious bronchitis viruses of Mass. and Conn. types (Polybron®) and the B1 strain of Newcastle virus. The viruses are grown under exacting standards of quality control in eggs produced by healthy chickens in closely supervised flocks.
Gentamicin is added as a preservative.
Precaution(s): Store vaccine in refrigerator under 45°F (7°C). Use entire contents of each vial when first opened. Burn containers and all unused contents.
Caution(s): Only vaccinate healthy chickens.
Consult your poultry pathologist for further recommendations based on conditions existing in your area at any given time.
The vaccination program for replacement pullets should not be started after chickens are 16 weeks of age.
Chickens should not be placed on contaminated premises. Exposure should be avoided immediately after vaccination because it takes up to 10 days to develop resistance.
All susceptible chickens on the same premises should be vaccinated at the same time. If this is not possible, then strict isolation and separate caretakers should be employed for non-vaccinated units. Efforts should be taken to reduce stressful conditions at the time the vaccine is administered.
Notice: All Schering-Plough Animal Health vaccines released for sale meet the requirements of the licensing authority (U.S. Department of Agriculture) in regard to safety, purity, potency and the capacity to immunize normal, susceptible chickens.
The capacity of this vaccine to produce satisfactory results depends upon many factors including, but not limited to, conditions of storage and handling by the user, administration of the vaccine, health and responsiveness of individual animals and the degree of field exposure.
