Blackleg & Gas-Gangrene Vaccine for Cattle and Sheep:
 


PRESENTATION :

Contains Blackleg vaccine and Gas-gangrene vaccine.
Bivalent Clostridial Vaccine is a liquid with a yellow coloured precipitate which resuspends on shaking , containing formalin inactivated clostridial antigens precipitated with potash alum.


 
 
 
 


INDICATIONS :
For the active immunisation of livestock, particulary cattle and occasionally for sheep against clostridial diseases caused by Cl, chauvoei ( blackquarter / blackleg and post - parturient gengrene) and Cl. Septicum (braxy and gas - gangrene ).


 
 
 
 


DOSAGE AND ADMINISTRATION :

Primary ( sensitising ) Revaccination dose dose
Cattle 5 ml 3 ml
Sheep 3 ml 2 ml

The container should be shaken well before doses are withdrawn . Administration is by subcutaneous injection. An initial course of immunisation is necessary comprising a primary (sensitizing) dose and a second dose which creates good immunity . The interval between these doses should be not less than 3 weeks. The primary course should be completed about 2 weeks before maximum immunity is required which may be either a period of high risk or during calving . calves born from cattle immunized with bivalent vaccine two weeks before calving should be protected until they are about 8 weeks of age . Because of the presence of maternally - derived antibodies, which may interfere with vaccination, these calves should not be vaccinated until they are 8 weeks of age. Calves born from cattle vaccinated with a 5 ml sensitizing dose should not be given their first dose of bivalent until they are 10-12 weeks of age, because the extended presence of maternally - derived antibodies may interfere with earlier vaccination . Revaccination is required at 6 monthly intervals for continuous protection, but if the risk is seasonal annual vaccination may suffice.


 
 
 
 


PRECAUTION :
Part - used bottles should be disposed of at the end of each day’s operation, as under field conditions it may be difficult to avoid accidental contamination of the vaccine .
As with all vaccines occasional hypersenitivity reactions may occur. In such cases appropriate treatment such as adrenalin or antihistamines should be administered without delay .
