Vaccinating with Toxovax has been shown to help prevent losses caused by Toxoplasmosis induced abortion storms and the lowered reproductive performance of affected ewes.
Vaccinations need to be timed around the date you plan to introduce the ram. Your vet can help plan an appropriate vaccination schedule for your farm to take control of your flocks performance.
Toxovax is a single dose vaccine that provides breeding ewes with lifetime protection against the effects of Toxoplasmosis. Vaccination with Toxovax increases lambing percentage by an average of 3% and decreases the incidence of dry ewes by an average of 14%.
Toxovax is a live vaccine, has a short shelf life and is made to order. Please order your Toxovax from your vet clinic at least four weeks before you need to use it, which should be at least 8 weeks before mating, to ensure supply.
Administered by intramuscular injection to non-pregnant ewes in the anterior (front) half of the neck. One injection only, at least 4 weeks before mating.
Pack size: 100 or 200 dose packs.
Toxoplasmosis in susceptible breeding ewes causes abortions, stillbirths and neonatal deaths. Research indicates that ewes infected with Toxoplasma in early gestation experience fetal death and resorption. This is often mistaken for ewe infertility and results in the unnecessary culling of otherwise fertile animals. Ewes infected in mid-gestation or later are likely to abort, or give birth to stillborn or weak lambs that fail to thrive.
Toxoplasmosis costs you in three ways:
Toxoplasmosis occurs throughout New Zealand. In fact, research shows it has been present on 100% of New Zealand sheep farms. Every sheep flock can be affected by ongoing insidious fetal losses and abortion storms. Ewe hoggets and two tooths are at most risk, but any ewe that contracts Toxoplasmosis for the first time while she is pregnant is likely to lose her lamb/s.
Often the farmer sees a reduced scanning percentage and a lot of late or dry ewes. Abortions are not always seen.
