The vaccine is given as a 1ml dose under the skin. All sheep should receive 1ml, irrespective of body weight. To ensure accuracy, it is better to use a 1ml fixed volume vaccinator, rather than an adjustable dose model. Behind the ear is a popular injection site. If a different vaccine (e.g. 5 in 1) is being given at the same time, it should be given at a different site e.g. on the opposite side of the neck. As with all vaccines self-injection of Barbervax could be painful.
A one-handed “safety” vaccinator is recommended to reduce the hazard.
The schedules that follow have been tailored for spring lambing flocks in the Northern Tablelands of NSW. Barbervax users lambing at other times of the year or in different parts of the country should email
info@barbervax.com.au for a customised vaccination programme or seek advice from their re-seller, vet or sheep advisor.
