Expand All
    • Glanvac® 6 B12 provides sheep with protection against cheesy gland and the main clostridial diseases with the added benefit of correcting cobalt deficiencies.
    • The prevention of cheesy gland in sheep flocks improves fibre production and increases the quality of sheep meat.
    • Cobalt is an essential trace element which is important for the production of vitamin B12 in the rumen. Cobalt deficiency can severely affect energy production which results is reduced fibre and meat production.


    • Maintains a high level of broad disease protection in the breeding flock.
    • Improves lambing and weaning percentages by preventing clostridial deaths such as pulpy kidney and tetanus
    • Improves meat quality through cheesy gland protection, ensuring export and domestic customers receive a quality product.
    • Improves fleece quality and quantity by protecting against cheesy gland.
    • Maintain a high level of vitamin B12 in pregnant and lactating ewes during periods of high requirement.


    • For the control of caseous lymphadenitis (cheesy gland); prevention of enterotoxaemia (pulpy kidney disease), prevention of tetanus, prevention of black disease, prevention of malignant oedema (blackleg-like disease) and swelled head in rams, prevention of blackleg in sheep and lambs.
    • Treatment and prevention of vitamin B12 deficiency in sheep, in areas of known or suspected cobalt deficiency.

  • Dose rate: 1mL for all classes of sheep

    Injection site: subcutaneously in the side of the neck just behind or below the base of the ear.


    Lambs need 2 doses:

    • First ‘priming’ dose at marking;
    • Second ‘booster’ dose at weaning


    Previously unvaccinated ewes need 2 doses:

    • First ‘priming’ dose at the time of joining or scanning;
    • Second ‘booster’ dose approximately 4 weeks before the expected date of lambing


    Other classes of previously unvaccinated sheep need 2 doses:

    • First ‘priming’ dose
    • Second ‘booster’ dose approximately 4 weeks after


    Previously vaccinated sheep need ‘annual booster’ vaccinations:

    • For ewes vaccinate 4 weeks before the expected date of lambing.
    • This should pass temporary immunity to their lambs in the colostrum, or first milk, to protect them for the first 6 to 8 weeks of their lives.

    Where possible give the annual booster at least 2 weeks prior to the time of maximum risk, e.g. transfer to lush pasture or grain feeding in the case of enterotoxaemia.
