Vaccinating Sheep


Most vaccines have important timings, but TOXOVAX and Androvax Plus are the most important to get right. Talk to us to ensure your timing is right.


Camplylobacter is present on virtually all New Zealand farms. On unvaccinated farms, lamb losses (usually in 2 tooths) can exceed 9%, so its worth doing. Campyvax4 is the vaccine that covers the widest range in NZ and stimulates an excellent immune response.


Toxoplasmosis is also extremely common. Transmitted via cats, toxoplasmosis can be a significant cause of abortion. This vaccine is a live vaccine, and a single dose generates lifelong immunity. Because vaccination is with a live vaccine, this cannot take place within 4 weeks of mating (can cause abortions).

Androvax® plus

A vaccine that increases fecundity in breeding ewes, increasing lambing percentage by an average 20%. Raises antibody levels, causing a change in hormone production which temporarily blocks the release of eggs from the ovaries. More eggs mature and when antibody levels fall these extra eggs are released, thus increasing the number of lambs born. Please talk to a vet if you are considering using this for the first time.

(An alternative is Ovistim - Talk to us for more information).



If we are going to have a salmonella year, this one is shaping up nicely - ewes are worth a fortune and there is plenty of feed around. The main risk period for us is early summer until late autumn. If you have had trouble before, consider vaccinating the ewes now.

As always, if you have any queries please contact one of the vets in person or by phone. Each clinic has a neat little software tool to help sort out dates for your flocks. When your vaccine arrives in clinic you will get a call asap (Toxovax arrives on Tuesday afternoons).


We adocate using a clostridial vaccine pre lambing for ewes. Traditionally  based around a 5 in 1 vaccine such as Ultravac 5 in 1 or Multine, many farmers are now using Ultravac 6 in 1 SD and Covexin 10 in 1 for high value stock, and for animals in challenging situations (e.g. rapidly growing young stock grazing crops behind wires). Emerging clostridial bugs such as Clostridium sordelli are causing stock losses in flock/herds well covered by the traditional 5 in 1 vaccination.
